Overall Summary

Study Background and Main Findings

This study presents a large-scale empirical analysis of AI usage across economic tasks, using over four million conversations from Claude.ai mapped to the O*NET database. The analysis reveals that AI usage is primarily concentrated in software development and writing tasks, accounting for nearly half of the observed usage. However, approximately 36% of occupations show AI usage in at least a quarter of their associated tasks, indicating a broader diffusion. The study distinguishes between AI usage for augmentation (57%) and automation (43%), finding a slightly higher prevalence of augmentation. AI usage peaks in occupations with wages in the upper quartile and those requiring considerable preparation (e.g., a bachelor's degree). The study acknowledges limitations, including the data being from a single platform and potential biases in the methodology.

Research Impact and Future Directions

The study provides a novel and valuable contribution to understanding AI usage in the economy by leveraging a large dataset of Claude.ai conversations and mapping them to the O*NET database. The framework allows for granular, task-level analysis and dynamic tracking of AI adoption. However, the study's conclusions are primarily correlational, not causal. The analysis demonstrates associations between AI usage and various factors (occupation, wage, skills), but it cannot definitively determine cause-and-effect relationships. For instance, while AI usage is higher in certain occupations, it's unclear if AI *causes* changes in those occupations or if pre-existing characteristics of those occupations lead to greater AI adoption.

The practical utility of the findings is significant, offering a framework for monitoring AI's evolving role in the economy. The task-level analysis provides valuable insights for businesses, policymakers, and workers seeking to understand and adapt to the changing landscape of work. The findings regarding augmentation versus automation are particularly relevant, suggesting that AI is currently used more as a collaborative tool than a replacement for human labor. However, the study's focus on a single platform (Claude.ai) limits the generalizability of the results to other AI systems and user populations.

The study provides clear guidance for future research, emphasizing the need for longitudinal studies, investigation of causal relationships, and expansion to other AI platforms. It acknowledges key uncertainties, such as the long-term economic impacts of AI adoption and the potential for bias in the data and classification methods. The authors appropriately caution against over-interpreting the findings and highlight the need for ongoing monitoring and analysis.

Critical unanswered questions remain, particularly regarding the causal mechanisms driving AI adoption and its impact on employment and wages. While the study identifies correlations, it cannot determine whether AI usage *causes* changes in occupational structure or productivity. The limitations of the data source (a single AI platform) and the potential for bias in the model-driven classification fundamentally affect the interpretation of the results. While the study provides a valuable snapshot of AI usage, it's crucial to acknowledge that the findings may not be representative of the broader AI landscape or the overall workforce. Further research is needed to address these limitations and to explore the long-term consequences of AI adoption.

We map conversations from Claude.ai to occupational categories in the U.S. Department of Labor's O*NET Database to surface current usage patterns. Our approach provides an automated, granular, and empirically grounded methodology for tracking Al's evolving role in the economy. (Note: figure contains illustrative conversation examples only.)
First Reference in Text
Provide the first large-scale empirical measurement of which tasks are seeing AI use across the economy (Figure 1, Figure 2, and Figure 3) Our analysis reveals highest use for tasks in software engineering roles (e.g., software engineers, data scientists, bioinformatics technicians), professions requiring substantial writing capabilities (e.g., technical writers, copywriters, archivists), and analytical roles (e.g., data scientists).
Description
  • Framework Overview: The figure serves as an overview of the research framework. The key aspect is the mapping of conversations from Claude.ai, an AI assistant, to occupational categories as defined in the U.S. Department of Labor's O*NET (Occupational Information Network) database. The O*NET database is a comprehensive resource that describes various occupations and the tasks, skills, knowledge, abilities, and other characteristics associated with them.
  • Mapping Process: The figure illustrates the process of connecting user conversations with the AI to specific tasks within those occupational categories. This involves analyzing conversations to identify the relevant tasks being performed and then categorizing these tasks according to the O*NET framework. The illustrative conversation examples provided in the figure (though not numerically specified in the caption) provide concrete instances of how these connections are made.
  • Additional Framework Aspects: The framework also includes the use of wage data and augmentative vs. automative task categorizations. Augmentative tasks refer to how AI can be used to augment human capabilities, whereas automative tasks are those where AI can be used to automate tasks. Finally, the figure also includes a section on skills breakdown, that are relevant to human-AI conversations.
Scientific Validity
  • Alignment with Objective: The figure's caption aligns with the study's objective of providing an empirical measurement of AI usage across different economic tasks. By grounding the analysis in the O*NET database, the study leverages a standardized and well-established framework for categorizing occupations and tasks. The mention of an 'automated, granular, and empirically grounded methodology' suggests a rigorous approach to data collection and analysis, enhancing the credibility of the findings.
  • Temporal Context: The caption's reference to 'current usage patterns' acknowledges the dynamic nature of AI adoption and the need for ongoing monitoring. While the caption itself does not delve into specific methodological details, it sets the stage for a more in-depth discussion of the data analysis techniques employed in the study, which should be elaborated upon in the methods section.
  • Limitations: It would strengthen the scientific validity to briefly mention the limitations inherent in using conversation data from a single AI platform (Claude.ai) and the potential biases that may arise from this specific data source.
Communication
  • Clarity and Summary: The caption effectively summarizes the core purpose of Figure 1, highlighting its role in measuring AI usage across the economy and linking it to the methodology used (Claude.ai conversations mapped to O*NET). The parenthetical note is helpful in managing reader expectations, clarifying that the figure contains illustrative examples rather than comprehensive data.
  • Technical Language: The phrase 'automated, granular, and empirically grounded methodology' is informative for a scientific audience, conveying the rigor and detail of the approach. However, for a broader audience, a slightly more accessible phrasing might improve understanding without sacrificing precision.

First Reference in Text
Provide the first large-scale empirical measurement of which tasks are seeing AI use across the economy (Figure 1, Figure 2, and Figure 3) Our analysis reveals highest use for tasks in software engineering roles (e.g., software engineers, data scientists, bioinformatics technicians), professions requiring substantial writing capabilities (e.g., technical writers, copywriters, archivists), and analytical roles (e.g., data scientists).
Description
  • Overall Structure: The figure presents a series of bar charts showing the relative amount of AI usage within the top six occupational categories. Each category is broken down into individual occupations listed in the O*NET database, showing the percentage of total conversations associated with each. For example, 'Computer and Mathematical' occupations show 37.2% of all conversations, with specific titles like 'Computer Programmers' (6.1%) and 'Software Developers, Systems Software' (5.3%) listed below.
  • Granularity of Data: Within each occupation, specific tasks are also listed, along with their percentage contribution to that occupation's AI usage. For instance, within 'Computer and Mathematical' occupations, 'Develop and maintain software' accounts for 16.8% of AI usage, while 'Program and debug computer systems and machinery' accounts for 6.9%. This provides a granular view of AI application within each field.
  • O*NET Explanation: The 'O*NET occupations' are classifications from the U.S. Department of Labor's Occupational Information Network (O*NET) database. This database categorizes jobs based on required skills, knowledge, and activities. The percentage values represent the proportion of Claude.ai conversations that are associated with tasks falling under each specified occupation or task category, providing a measure of AI usage within those areas.
Scientific Validity
  • Empirical Support: The figure provides empirical support for the claim that AI usage is concentrated in specific occupational categories, particularly software engineering. The hierarchical structure allows for a detailed examination of AI adoption at different levels of granularity, from broad categories to specific tasks.
  • Mapping Accuracy: The validity of the figure depends on the accuracy of the mapping between Claude.ai conversations and O*NET occupations and tasks. This mapping process should be clearly described in the methodology section, including any validation steps taken to ensure the reliability of the assignments. It would also be valuable to discuss potential sources of error or bias in the mapping process.
  • Category Selection: The choice of the 'top six' occupational categories should be justified based on a clear and objective criterion (e.g., overall AI usage). Presenting data for a larger number of categories or including a category for 'other' occupations would provide a more comprehensive picture of AI adoption across the economy.
Communication
  • Clarity of Purpose: The caption clearly states the purpose of Figure 2: to present a hierarchical breakdown of AI usage across the top six occupational categories. The phrase 'highest levels of appearance in Claude.ai interactions' is specific and accurately reflects the data source and metric used.
  • Accessibility: For a general audience, the term 'hierarchical breakdown' might benefit from a brief explanation. However, for a scientific audience familiar with data visualization, the term is likely sufficient. The caption could be enhanced by explicitly stating the criteria used to determine the 'top six' categories (e.g., overall AI usage).

Provide the first large-scale empirical measurement of which tasks are seeing AI use across the economy (Figure 1, Figure 2, and Figure 3) Our analysis reveals highest use for tasks in software engineering roles (e.g., software engineers, data scientists, bioinformatics technicians), professions requiring substantial writing capabilities (e.g., technical writers, copywriters, archivists), and analytical roles (e.g., data scientists).
Description
  • Visual Representation: The figure likely consists of a set of horizontal bar graphs. Each bar represents an occupational category. There are two bars for each occupation, one represents the percentage of Claude.ai conversations that are associated with that occupation, and the other represents the percentage of the US workforce that are in the same occupation. This allows for a direct comparison of AI usage and real-world employment.
  • Key Trends: The caption highlights a key trend that the occupations with the most usage in Claude.ai are tasks associated with software development (37.2%), technical writing (10.3%), and analytical tasks. The occupations with the lowest usage in Claude.ai are tasks associated with physical manipulation or extensive specialized training.
  • BLS Data: The U.S. Bureau of Labor Statistics (BLS) data provides a baseline for understanding the overall composition of the U.S. workforce. The BLS collects data on employment, unemployment, earnings, and other labor market characteristics. By comparing the AI usage data with the BLS data, the researchers can identify occupations that are disproportionately represented in AI interactions.
Scientific Validity
  • Methodological Soundness: Comparing AI usage data with the overall occupational distribution in the U.S. economy is a scientifically sound approach for identifying potential biases and understanding the broader implications of AI adoption. This comparison helps to contextualize the AI usage patterns and assess whether AI is being used in a representative manner across different sectors.
  • Data Comparability: The validity of the comparison depends on the accuracy and comparability of the occupational categories used in the Claude.ai data and the BLS data. It is essential that the researchers have carefully mapped the occupational categories to ensure consistency and avoid introducing bias. The methodology section should provide details on this mapping process.
  • Limitations of BLS Data: It is important to acknowledge potential limitations in the BLS data, such as the level of granularity in the occupational categories and the potential for measurement error. The researchers should also consider whether the BLS data accurately reflects the current state of the U.S. economy, given that labor market conditions can change rapidly.
Communication
  • Clarity of Purpose: The caption clearly indicates the purpose of Figure 3: to compare the distribution of occupations represented in the Claude.ai usage data with the overall occupational distribution in the U.S. economy. This comparison provides valuable context for interpreting the AI usage data, highlighting potential biases or over/under-representation of certain sectors.
  • Summary of Findings: The caption effectively summarizes the key findings, noting the high representation of software development, technical writing, and analytical tasks, and the low representation of occupations involving physical manipulation or specialized training. This provides a concise overview of the main trends revealed by the figure.
  • Source Transparency: The reference to the U.S. Bureau of Labor Statistics (BLS) as the source for U.S. representation data is crucial for transparency and allows readers to assess the reliability and validity of the comparison. Specifying that the U.S. representation is computed as 'the fraction of workers in each high-level category' provides a clear definition of the metric used.

Figure 7: Distribution of automative behaviors (43%) where users delegate tasks to AI, and augmentative behaviors (57%) where users actively collaborate with AI. Patterns are categorized into five modes of engagement; automative modes include Directive and Feedback Loop, while augmentative modes are comprised of Task Iteration, Learning, and Validation.

Figure 7: Distribution of automative behaviors (43%) where users delegate tasks to AI, and augmentative behaviors (57%) where users actively collaborate with AI. Patterns are categorized into five modes of engagement; automative modes include Directive and Feedback Loop, while augmentative modes are comprised of Task Iteration, Learning, and Validation.
First Reference in Text
Assess whether people use Claude to automate or augment tasks (Figure 7) We find that 57% of interactions show augmentative patterns (e.g., back-and-forth iteration on a task) while 43% demonstrate automation-focused usage (e.g., performing the task directly).
Description
  • Visual Representation: Figure 7 likely presents a pie chart or bar graph showing the distribution of automative and augmentative behaviors. The two main categories are 'automative behaviors' and 'augmentative behaviors'. Automative behaviors are those where the user delegates tasks to the AI, and they are made up of 'Directive' and 'Feedback Loop' modes. Augmentative behaviors are those where the user collaborates with the AI, and they are made up of 'Task Iteration', 'Learning', and 'Validation' modes.
  • Key Finding: The key finding is that augmentative behaviors (57%) are slightly more prevalent than automative behaviors (43%). This suggests that users are more likely to actively collaborate with AI than to simply delegate tasks to it. This may reflect the current limitations of AI capabilities, or a preference for human control and oversight in certain tasks.
  • Automative Behaviors: 'Automative behaviors' are those where the user delegates tasks to the AI, and they are made up of 'Directive' and 'Feedback Loop' modes. 'Directive' mode is where the human gives the AI a single instruction to complete, without much interaction. 'Feedback Loop' mode is where the human and AI engage in iterative dialogue, with the human mainly providing feedback.
  • Augmentative Behaviors: 'Augmentative behaviors' are those where the user collaborates with the AI, and they are made up of 'Task Iteration', 'Learning', and 'Validation' modes. 'Task Iteration' mode is where the human and AI iteratively refine a task, with the human refining AI outputs. 'Learning' mode is where the human seeks understanding and explanation from the AI, and 'Validation' mode is where the human uses AI to check or validate work.
Scientific Validity
  • Significance of Findings: The figure provides empirical evidence on the relative prevalence of automation and augmentation in human-AI interactions. This distinction is important for understanding the potential impact of AI on the labor market, as automation may lead to job displacement, while augmentation may enhance human productivity and creativity.
  • Classification Method: The validity of the figure depends on the accuracy of the method used to classify conversations into the different modes of engagement. This classification method should be clearly described in the methodology section, including any validation steps taken to ensure the reliability of the classifications. It should also be shown that the categorization is robust and accounts for edge cases.
  • Potential Variations: It is important to acknowledge that the distribution of automative and augmentative behaviors may vary depending on the specific tasks being performed and the characteristics of the users. Further analysis is needed to explore these potential variations and identify the factors that influence the choice of collaboration mode.
Communication
  • Clarity of Distribution: The caption clearly presents the distribution of automative and augmentative behaviors, providing the percentages for each category (43% and 57%, respectively). This offers a concise overview of the overall balance between these two modes of AI usage.
  • Mode Categorization: The caption effectively lists the five modes of engagement and assigns them to either the automative or augmentative category. This provides a clear and structured understanding of the different types of human-AI interactions being analyzed. The use of specific names for each mode (Directive, Feedback Loop, Task Iteration, Learning, Validation) enhances the clarity and memorability of the taxonomy.
  • Accessibility: For a broader audience, brief examples of each mode of engagement would enhance the caption's accessibility. However, for a scientific audience familiar with the concepts of automation and augmentation, the current level of detail is likely sufficient.

First Reference in Text
Analyze how wage and barrier to entry correlates with AI usage (Figure 6 and Table 2).
Description
  • Table Structure: Table 2 likely presents a breakdown of AI usage across different 'Job Zones'. Job Zones are categories defined by the U.S. Department of Labor's O*NET database, and they represent the amount of preparation needed for a human to perform the duties of a given occupation. The table likely consists of several columns, with each row corresponding to a different Job Zone.
  • Relative Usage Rates: The table shows 'relative usage rates compared to baseline occupational distribution'. This means that the researchers are comparing the percentage of AI conversations associated with each Job Zone to the percentage of the U.S. workforce that is in the same Job Zone. This comparison reveals whether AI usage is over- or under-represented in different Job Zones, relative to their overall presence in the labor market.
  • Key Finding: The key finding is that AI usage 'peaks in Job Zone 4'. This means that the relative usage rate is highest for occupations requiring considerable preparation, such as a bachelor's degree. The 'lower usage in zones requiring minimal or extensive preparation' suggests that AI tools may not be well-suited for either very simple or very complex tasks.
Scientific Validity
  • Analytical Approach: Analyzing AI usage in relation to occupational barriers to entry is a valuable approach for understanding the factors that influence AI adoption. The use of Job Zones as a measure of barriers to entry provides a standardized and well-defined framework for this analysis.
  • Mapping Accuracy: The scientific validity of the table depends on the accuracy of the mapping between AI conversations and Job Zones. This mapping process should be clearly described in the methodology section, including any steps taken to ensure the reliability of the assignments. Potential sources of error or bias in the mapping process should be acknowledged.
  • Limitations of Job Zones: It is important to consider potential limitations in the Job Zone classification system, such as the granularity of the categories and the potential for subjectivity in assigning occupations to different zones. The researchers should also acknowledge that other factors, such as the availability of AI tools for different occupations and the regulatory environment, may also influence AI adoption.
Communication
  • Clarity and Conciseness: The caption provides a clear overview of Table 2's purpose: to analyze AI usage in relation to occupational barriers to entry. It clearly defines the range of Job Zones being considered (1 to 5) and provides a concise summary of the key finding: peak usage in Job Zone 4.
  • Accessibility: The parenthetical descriptions of each Job Zone (e.g., 'minimal preparation required', 'extensive preparation required') enhance the caption's accessibility for a broader audience. The explicit mention of 'a bachelor's degree' as an example of the preparation required for Job Zone 4 further clarifies the meaning of the different levels of preparation.

Figure 4: Depth of AI usage across occupations. Cumulative distribution showing what fraction of occupations (y-axis) have at least a given fraction of their tasks with AI usage (x-axis). Task usage is defined as occurrence across five or more unique user accounts and fifteen or more conversations. Key points on the curve highlight that while many occupations see some AI usage (~36% have at least 25% of tasks), few occupations exhibit widespread usage of AI across their tasks (only ~4% have 75% or more tasks), suggesting AI integration remains selective rather than comprehensive within most occupations.

First Reference in Text
As shown in Figure 4, we find that AI task use follows a heavily skewed distribution.
Description
  • Cumulative Distribution: Figure 4 presents a cumulative distribution function (CDF). A CDF plots the probability that a real-valued random variable X takes on a value less than or equal to x. In this case, the y-axis shows the cumulative fraction of occupations, and the x-axis shows the fraction of tasks within each occupation that utilize AI. So, for any point on the curve, the y-value tells us the proportion of occupations for which at least that proportion of their tasks are being performed using AI.
  • Axis Interpretation: The x-axis represents the 'fraction of tasks with AI usage'. A value of 0.25 on the x-axis means that 25% of the tasks associated with a particular occupation are being performed with the assistance of AI. The y-axis indicates the 'fraction of occupations'. A value of 0.36 on the y-axis at the x-axis value of 0.25 means that 36% of occupations have at least 25% of their tasks performed with AI.
  • Task Usage Definition: The caption defines 'task usage' as 'occurrence across five or more unique user accounts and fifteen or more conversations'. This is a threshold applied to filter out tasks that are only performed sporadically or by a small number of users. It implies that the data used to generate the figure only considers tasks with a substantial level of adoption across multiple users of Claude.ai.
Scientific Validity
  • Appropriateness of CDF: The use of a cumulative distribution function (CDF) is appropriate for visualizing the distribution of AI usage across occupations. The CDF effectively illustrates the proportion of occupations that have at least a certain fraction of their tasks performed with AI. The CDF is a standard statistical tool for visualizing distributions, and its use is well-justified in this context.
  • Justification of Thresholds: The definition of 'task usage' as 'occurrence across five or more unique user accounts and fifteen or more conversations' is a reasonable approach for filtering out noise and focusing on tasks with substantial adoption. However, the specific thresholds (five users and fifteen conversations) should be justified based on methodological considerations and sensitivity analyses. The impact of varying these thresholds on the overall results should be explored.
  • Complementary Analyses: The CDF provides a valuable overview of the depth of AI integration across occupations, but it does not reveal information about which specific tasks are being performed with AI or the impact of AI on task performance. Complementary analyses that delve into the specific tasks and their associated outcomes would provide a more complete picture of AI adoption.
Communication
  • Clarity and Conciseness: The caption provides a clear and concise summary of the figure's content, including the type of visualization (cumulative distribution), the variables represented on each axis (fraction of occupations vs. fraction of tasks with AI usage), and the definition of 'task usage'. The inclusion of key data points (36% and 4%) further enhances its informativeness.
  • Key Takeaway: The caption effectively highlights the main takeaway from the figure: that AI integration remains 'selective rather than comprehensive'. This provides a valuable interpretation of the data and guides the reader's understanding of the figure's significance.
  • Accessibility: For a broader audience, the term 'cumulative distribution' might benefit from a brief, intuitive explanation. However, for a scientific audience familiar with statistical visualizations, the term is likely sufficient. The caption effectively uses approximations (~36% and ~4%) to convey the key data points without overwhelming the reader with precise numbers.

the occupational skills exhibited by the moel in relevant to a given Claude.ai conversation, shown in Figure 5.
Description
  • Visual Representation: The figure likely presents a horizontal bar chart displaying the distribution of various occupational skills. Each bar represents a specific skill (e.g., critical thinking, writing, programming), and the length of the bar indicates the percentage of Claude.ai conversations in which that skill is exhibited.
  • O*NET Skills: The skills are derived from the O*NET database, which identifies 35 occupational skills that are essential for workers to perform tasks across different jobs. These skills encompass a wide range of abilities, including cognitive, interpersonal, and physical skills.
  • Skill Distribution: The caption notes that skills like critical thinking, writing, and programming have a high presence in AI conversations. This suggests that AI is being used to support tasks that require these cognitive abilities. The figure probably shows that skills like equipment maintenance and installation are uncommon, which suggests that AI is not frequently used for tasks that require physical manipulation.
Scientific Validity
  • Empirical Support: The figure provides empirical support for the claim that AI interactions are more strongly associated with cognitive skills than with manual skills. This finding aligns with the broader trends observed in AI adoption, where AI is often used to augment or automate tasks that require cognitive abilities.
  • Skill Identification Method: The validity of the figure depends on the accuracy of the method used to identify the occupational skills exhibited in Claude.ai conversations. This method should be clearly described in the methodology section, including any validation steps taken to ensure the reliability of the skill assignments. Further analysis should also consider whether Claude's responses are reflecting actual skill performance, or simply reflecting default conversational behaviors.
  • Limitations of O*NET Skills: It is important to acknowledge potential limitations in the O*NET database, such as the comprehensiveness of the skill list and the potential for overlap between different skills. The researchers should also consider whether the O*NET skills accurately reflect the current demands of the labor market.
Communication
  • Clarity and Summary: The caption clearly summarizes the figure's content, highlighting the distribution of occupational skills exhibited in Claude.ai conversations. The use of specific examples (critical thinking, writing, programming, equipment maintenance, and installation) enhances the clarity and informativeness of the caption.
  • Key Takeaway: The caption effectively conveys the main takeaway from the figure: that cognitive skills are more prevalent in AI interactions than manual skills. This provides a valuable insight into the nature of AI adoption and its potential impact on different types of work.

Description
  • Visual Representation: Figure 6 likely presents a scatter plot. The x-axis represents the annual wage of an occupation, likely in US dollars. The y-axis represents a measure of Claude.ai usage within that occupation. Each point on the plot represents a different occupation. The position of the point reflects the wage and AI usage level for that occupation. The higher a point is, the more that occupation uses Claude.ai.
  • Key Trends: The caption indicates that occupations like Computer Programmers and Software Developers are 'notable outliers'. This means that these occupations have a higher-than-expected AI usage level for their respective wage ranges, relative to the general trend. The lowest and highest wage percentiles have 'substantially lower usage rates'. This means that occupations in the lowest and highest wage ranges have a lower AI usage than occupations at mid-range wages.
  • Wage Data: The wage data is sourced from the U.S. Census Bureau. The U.S. Census Bureau is a primary source of data on the U.S. population and economy, including income and wage statistics. The 'upper wage quartile' refers to the top 25% of wage earners in the U.S. workforce. This is used as a benchmark to measure the wages of different occupations.
Scientific Validity
  • Analytical Approach: The figure presents a valuable analysis of the relationship between AI usage and occupational wages. The use of a scatter plot is appropriate for visualizing the relationship between two continuous variables. The identification of outliers and the overall trend provides a basis for further investigation into the factors that may influence AI adoption.
  • Data Accuracy: The validity of the figure depends on the accuracy of the wage data and the AI usage data. The researchers should clearly describe the sources of these data and any steps taken to ensure their reliability. Potential sources of error or bias in the data should be acknowledged.
  • Causality: While the figure reveals a correlation between AI usage and occupational wages, it does not establish a causal relationship. Other factors, such as the nature of the tasks performed in different occupations and the availability of AI tools for those tasks, may also influence AI adoption. Further research is needed to explore the underlying mechanisms driving the observed relationship.
Communication
  • Clarity and Conciseness: The caption provides a clear and concise summary of the figure's content: the relationship between occupational usage of Claude.ai and annual wages. It effectively highlights the key findings, including the concentration of usage in mid-to-high wage professions and the lower usage rates at both extremes of the wage spectrum.
  • Key Findings: The mention of 'notable outliers' (Computer Programmers and Software Developers) draws attention to specific occupations that deviate from the general trend, providing valuable insights into the factors that may influence AI adoption. The reference to the U.S. Census Bureau as the source for wage data ensures transparency and allows readers to assess the reliability of the data.
  • Accessibility: For a broader audience, the term 'wage percentiles' might benefit from a brief, intuitive explanation. However, for a scientific audience familiar with statistical concepts, the term is likely sufficient. The caption effectively uses the phrase 'upper wage quartile' to convey the general location of the peak usage, without overwhelming the reader with precise wage values.

grouped into automative vs. augmentative behaviors, listed in Table 1.
Description
  • Collaboration Patterns: Table 1 likely contains a detailed breakdown of the five distinct collaboration patterns. These patterns describe how humans and AIs interact and collaborate in different scenarios. Each pattern probably has a distinct name and a description. The description will specify how the human and AI interact, the type of tasks involved, and the overall goal of the collaboration.
  • Broad Categories: The two broad categories mentioned in the caption likely represent a higher-level classification of the collaboration patterns. These categories probably represent different approaches to AI integration, such as 'automation' and 'augmentation'. Each collaboration pattern in the table should fall under one of these two categories.
  • Automative vs. Augmentative: Since the reference text mentions 'automative' vs. 'augmentative' behaviors, the two categories mentioned in the caption will likely represent the extent to which AI automates tasks for humans versus augments human capabilities.
Scientific Validity
  • Framework Value: The taxonomy provides a valuable framework for categorizing and analyzing human-AI collaboration patterns. The use of distinct patterns and broad categories allows for a structured and systematic examination of the different ways in which people integrate AI into their workflow.
  • Pattern Distinctiveness: The scientific validity of the taxonomy depends on the clarity and distinctiveness of the collaboration patterns. The patterns should be mutually exclusive and collectively exhaustive, meaning that each conversation can be classified into only one pattern, and that all possible conversations can be classified into one of the patterns.
  • Classification Method: The taxonomy's validity also depends on the method used to classify conversations into the different patterns. This classification method should be clearly described in the methodology section, including any validation steps taken to ensure the reliability of the classifications. It is crucial to have inter-rater reliability to ensure that different raters classify the same conversations into the same categories.
Communication
  • Clarity and Overview: The caption clearly introduces Table 1 as a taxonomy of human-AI collaboration patterns. It states that conversations are classified into five distinct patterns, grouped into two broad categories. This provides a clear overview of the table's structure and content.
  • Accessibility: The phrase 'how people integrate AI into their workflow' is accessible and effectively conveys the focus of the taxonomy. The caption effectively summarizes the core purpose of the table without overwhelming the reader with technical details.

Figure 8: Comparative analysis of task usage patterns between Claude Sonnet 3.5 (New) and Claude Opus models, showing differential preferences in usage. Sonnet 3.5 (New) demonstrates more usage for coding and technical tasks, while Opus is more used for creative writing and educational content development.
First Reference in Text
Our analysis reveals clear specialization in how these models are used (Figure 8).
Description
  • Visual Representation: Figure 8 likely presents a set of bar charts or a similar visual representation comparing the usage patterns of Claude Sonnet 3.5 (New) and Claude Opus across different tasks. The figure shows the differential preferences in task distribution for the two Claude models. The tasks would likely be aligned vertically, with the percentage point difference in task distribution between the two models shown for each task.
  • Model Specialization: The caption notes that Sonnet 3.5 (New) demonstrates more usage for coding and technical tasks. This suggests that this model is better suited for tasks that require logical reasoning, problem-solving, and attention to detail. The caption also notes that Opus is more used for creative writing and educational content development. This suggests that this model is better suited for tasks that require creativity, imagination, and communication skills.
  • Percentage Point Difference: The figure displays a 'percentage point difference in task distribution'. A percentage point is the arithmetic difference of two percentages. For example, if Sonnet 3.5 (New) has 10% usage for coding tasks, and Opus has 5% usage for coding tasks, then the percentage point difference is 5 percentage points. This is a useful way to compare the relative usage of the two models across different tasks.
Scientific Validity
  • Significance of Findings: The figure provides valuable insights into the specialization of different AI models for specific tasks. This information is important for understanding the capabilities and limitations of different AI models and for guiding their appropriate use.
  • Measurement Method: The validity of the figure depends on the accuracy of the method used to measure task usage patterns for each model. This method should be clearly described in the methodology section, including any steps taken to ensure the comparability of the data across the two models. This would involve controlling for any confounding factors that may influence the observed differences.
  • Statistical Significance: It is important to consider whether the observed differences in task usage patterns are statistically significant. A statistical test should be used to determine whether the differences are likely due to chance or reflect a real specialization of the models. Further exploration is needed to determine whether the observed differences in task usage translate into differences in task performance or user satisfaction.
Communication
  • Clarity and Conciseness: The caption clearly describes the figure as a comparative analysis of task usage patterns between two specific Claude models, Sonnet 3.5 (New) and Opus. It highlights the key finding: differential preferences in usage, with Sonnet 3.5 (New) favored for coding and technical tasks, and Opus for creative writing and educational content development.
  • Key Findings: The caption effectively summarizes the specialization of each model, providing a concise overview of their respective strengths. This allows readers to quickly understand the figure's main message and its implications for AI adoption.

Figure 9: Example subsection of the generated O*NET task hierarchy. Our hierarchy contains three levels: 12 top-level tasks, 474 middle-level tasks, and 19530 base-level (O*NET) tasks.
First Reference in Text
We instead construct this as a classification over a hierarchy of task labels (Figure 9), inspired by Morin and Bengio [2005], Mnih and Hinton [2008].
Description
  • Task Hierarchy: Figure 9 likely presents a tree-like diagram illustrating a portion of the generated task hierarchy. The hierarchy is a way of organizing a large number of tasks into a structured framework. The O*NET database contains a very large number of tasks. Creating a hierarchy of tasks is helpful in reducing complexity.
  • Hierarchy Levels: The hierarchy consists of three levels: top-level tasks, middle-level tasks, and base-level tasks. The base-level tasks are the original tasks from the O*NET database. The top-level and middle-level tasks are broader categories that group related base-level tasks together. The number of tasks at each level is specified in the caption: 12 top-level tasks, 474 middle-level tasks, and 19530 base-level tasks.
  • O*NET Database: The O*NET database is the U.S. Department of Labor's Occupational Information Network (O*NET) database. The O*NET database is a comprehensive resource that describes various occupations and the tasks, skills, knowledge, abilities, and other characteristics associated with them. The figure shows an 'example subsection', meaning it only shows a small portion of the whole task hierarchy.
Scientific Validity
  • Hierarchical Classification: The use of a task hierarchy is a sound approach for organizing and classifying a large number of tasks. Hierarchical classification is a common technique in machine learning and other fields for dealing with complex datasets.
  • Hierarchy Generation Method: The scientific validity of the figure depends on the method used to generate the task hierarchy. This method should be clearly described in the methodology section, including the criteria used to group tasks together at different levels of the hierarchy. The hierarchy needs to be meaningful and reflect real-world relationships between tasks. The validity could be strengthened by conducting human validation.
  • Established Techniques: The reference to Morin and Bengio [2005] and Mnih and Hinton [2008] suggests that the researchers are drawing on established techniques for hierarchical classification. It would be helpful to explain how these techniques were adapted and applied to the specific context of O*NET tasks.
Communication
  • Clarity and Structure: The caption clearly introduces Figure 9 as an example of the generated O*NET task hierarchy. It specifies the three levels of the hierarchy and the number of tasks at each level, providing a concise overview of the hierarchy's structure.
  • Accessibility: The use of the term 'O*NET task hierarchy' is appropriate for a scientific audience familiar with the O*NET database. However, for a broader audience, a brief explanation of the purpose and benefits of creating such a hierarchy would enhance the caption's accessibility.

Figure/Table Image (Page 19)
Figure 10: We observe minimal difference in our measurements of AI use across occupational categories when measuring by number of conversations versus number of accounts
First Reference in Text
As shown in Figure 10, the patterns of AI usage across occupations remain remarkably stable regardless of which approach we use.
Description
  • Visual Comparison: Figure 10 likely presents a visual comparison (e.g., side-by-side bar charts or a scatter plot) of AI usage across different occupational categories. The two methods of measuring AI usage are 'number of conversations' and 'number of accounts'. The first is a raw count of the number of individual conversations with Claude.ai, and the second is based on the number of unique user accounts engaging in those conversations.
  • Occupational Categories: The 'occupational categories' are classifications from the U.S. Department of Labor's Occupational Information Network (O*NET) database. These are categories of similar jobs that share common skill sets, education levels, and work activities. By comparing the AI usage measurements across these categories, the researchers are able to assess whether certain types of jobs are more likely to involve AI interactions.
  • Minimal Difference: The caption states that there is 'minimal difference' in the AI usage measurements between the two methods. This suggests that the overall patterns of AI usage across occupational categories are similar regardless of whether one counts the number of conversations or the number of unique user accounts. If there were a large difference, it would suggest that certain users are having far more conversations than others.
Scientific Validity
  • Robustness of Results: The figure provides evidence that the AI usage measurements are robust to the choice of measurement method. This increases confidence in the reliability of the findings and suggests that the observed patterns are not simply artifacts of the specific measurement approach used.
  • Statistical Methods: The scientific validity of the figure depends on the appropriateness of the statistical methods used to compare the two sets of measurements. The researchers should specify which statistical tests were used to assess the degree of agreement between the two measures (e.g., correlation coefficient, paired t-test).
  • Implications of Minimal Difference: It is important to consider the potential implications of the 'minimal difference' observed. While the overall patterns may be similar, there may still be subtle differences that are masked by the aggregate-level analysis. Further investigation could explore whether certain occupational categories exhibit larger discrepancies between the two measures.
Communication
  • Clarity and Summary: The caption clearly states the main finding: minimal difference in AI usage measurements across occupational categories, regardless of whether measured by number of conversations or number of accounts. This conveys a sense of robustness in the results.
  • Accessibility: The caption is concise and avoids technical jargon, making it accessible to a broad audience. It effectively communicates the central message without overwhelming the reader with unnecessary details.
Figure 11: Most prevalent top-level tasks.
Figure/Table Image (Page 22)
Figure 11: Most prevalent top-level tasks.
First Reference in Text
At the top-level (Figure 11), we see that IT, technology, and associated related tasks dominate the distribution, at nearly 50% of conversations.
Description
  • Visual Representation: Figure 11 likely presents a horizontal bar chart or a similar visual representation displaying the most prevalent top-level tasks. Each bar represents a different top-level task, and the length of the bar indicates the percentage of Claude.ai conversations associated with that task. These are the highest level categories in the O*NET task hierarchy.
  • Key Finding: The reference text notes that IT, technology, and associated related tasks dominate the distribution, accounting for nearly 50% of conversations. This suggests that AI is being used primarily to support tasks related to information technology and related fields. The figure probably shows a sharp drop-off in usage for tasks after IT, technology, and associated related tasks.
  • Top-Level Tasks: The term 'top-level tasks' refers to the highest level of categorization in the O*NET task hierarchy that the researchers created for their analysis. The O*NET (Occupational Information Network) is a database containing a large number of tasks. Rather than classify conversations directly into the tasks in O*NET, the authors created a hierarchy of tasks, in which similar O*NET tasks are grouped together.
Scientific Validity
  • Empirical Support: The figure provides empirical support for the claim that AI usage is concentrated in specific task areas, particularly IT and technology. This finding aligns with the broader trends observed in AI adoption, where AI is often used to automate or augment tasks that are computationally intensive or data-driven.
  • Classification Method: The validity of the figure depends on the method used to classify conversations into the different top-level tasks. This classification method should be clearly described in the methodology section, including any validation steps taken to ensure the reliability of the classifications. The validity could be strengthened by conducting human validation.
  • Level of Aggregation: The figure presents data at a high level of aggregation (top-level tasks). While this provides a useful overview of the main trends, it may mask important variations in AI usage at lower levels of the task hierarchy. Further analysis is needed to explore these potential variations and identify the specific tasks within the IT and technology domain that are driving the observed dominance.
Communication
  • Conciseness: The caption is concise and clearly identifies the figure's content: the most prevalent top-level tasks. This is directly informative but lacks detail about the underlying data or its implications.
  • Accessibility: For a broader audience, the caption could benefit from a brief explanation of what 'top-level tasks' refers to in the context of the study. Given it's in the Discussion section, it assumes the reader knows that it is a reference to the O*NET task hierarchy.
Figure 12: Most prevalent middle-level tasks.
Figure/Table Image (Page 23)
Figure 12: Most prevalent middle-level tasks.
First Reference in Text
At the middle-level (Figure 12), the data reveals more granular task patterns.
Description
  • Visual Representation: Figure 12 likely presents a horizontal bar chart displaying the most prevalent middle-level tasks. Each bar represents a different middle-level task, and the length of the bar indicates the percentage of Claude.ai conversations associated with that task. Middle-level tasks are intermediate categories in the O*NET task hierarchy.
  • Granular Task Patterns: The reference text states that 'the data reveals more granular task patterns' at the middle level. This suggests that Figure 12 provides a more detailed breakdown of AI usage compared to Figure 11, highlighting specific tasks that are driving the overall trends. The figure will likely show a wider variety of tasks than Figure 11, and these tasks will be more specific than the top-level tasks.
  • O*NET Task Hierarchy: The O*NET task hierarchy is a way of organizing the tasks listed in the U.S. Department of Labor's Occupational Information Network (O*NET) database. The researchers classified the tasks into three levels: top, middle, and base. This classification helps to identify patterns of AI usage at different levels of granularity.
Scientific Validity
  • Increased Granularity: The figure provides a more detailed view of AI usage patterns compared to Figure 11, allowing for a more nuanced understanding of how AI is being used across different tasks. This increased granularity is valuable for identifying specific areas where AI is having the greatest impact.
  • Task Classification: The scientific validity of the figure depends on the consistency and reliability of the task classification method. The researchers should ensure that the middle-level tasks are well-defined and that conversations are consistently assigned to the appropriate task categories. The validity could be strengthened by conducting human validation.
  • Category Definition: It is important to consider the potential for overlap and redundancy among the middle-level tasks. The researchers should address whether the categories are mutually exclusive and clearly defined to avoid skewing the results. A more robust analysis could account for the dependencies and relationships between different tasks.
Communication
  • Conciseness: The caption is concise and accurately identifies the figure's content: the most prevalent middle-level tasks. However, it lacks context about the figure's significance or relationship to the top-level tasks presented in Figure 11. A more informative caption could briefly explain why analyzing middle-level tasks is valuable.
  • Accessibility: For readers unfamiliar with the study's methodology, the term 'middle-level tasks' might not be immediately clear. A brief reminder of the hierarchical task structure would improve accessibility. Given it's in the Discussion section, it assumes the reader remembers the task hierarchy.
Figure 13: Most prevalent base-level (O*NET) tasks.
Figure/Table Image (Page 23)
Figure 13: Most prevalent base-level (O*NET) tasks.
First Reference in Text
At the base-level (O*NET tasks, Figure 13), we see highly-specific technical operations.
Description
  • Visual Representation: Figure 13 likely presents a horizontal bar chart displaying the most prevalent base-level tasks. Each bar represents a specific base-level task, and the length of the bar indicates the percentage of Claude.ai conversations associated with that task. These are the most granular tasks defined in the O*NET database, before the researchers grouped them into a hierarchy.
  • Specific Technical Operations: The reference text highlights that these base-level tasks are 'highly-specific technical operations'. This suggests that the figure provides a detailed view of how AI is being used to support very specific and technical activities in the workplace. The figure probably presents a long list of tasks, with the percentages indicating the relative frequency of each task in Claude.ai conversations.
  • O*NET Database: The O*NET database is the U.S. Department of Labor's Occupational Information Network (O*NET) database. This database is a comprehensive resource that describes various occupations and the tasks, skills, knowledge, abilities, and other characteristics associated with them. The base-level tasks represent the most detailed level of task description in the O*NET database.
Scientific Validity
  • Granular View: The figure provides the most granular view of AI usage patterns in the study, allowing for the identification of specific tasks that are being supported by AI. This level of detail is valuable for understanding the practical applications of AI in the workplace.
  • Task Classification: The scientific validity of the figure depends on the accuracy and reliability of the task classification method. The researchers should provide evidence that the conversations were accurately assigned to the appropriate base-level tasks. Given the large number of tasks, this classification process is likely to be complex and require careful attention to detail. The validity could be strengthened by conducting human validation.
  • Task Overlap: It is important to consider the potential for task overlap and redundancy at the base level. The researchers should address whether the tasks are mutually exclusive and clearly defined to avoid skewing the results. A more robust analysis could account for the dependencies and relationships between different tasks.
Communication
  • Conciseness: The caption clearly identifies the figure's content as the most prevalent base-level (O*NET) tasks. The directness is effective for a scientific audience, although it offers limited context on the figure's specific contribution to the analysis.
  • Accessibility: For readers less familiar with the O*NET database, a brief reminder of what O*NET is and what 'base-level tasks' represent would be helpful. Assuming prior knowledge of the O*NET hierarchy may limit comprehension for some readers.

Figure/Table Image (Page 28)
Figure 14: Comparison between the prevalence of occupational categories when determined via direct assignment compared to clusters at various aggregation levels.
First Reference in Text
We visualize these relationships in several ways. Figure 14 directly compares the prevalence of occupational categories between direct assignment and cluster-based approaches at different aggregation levels.
Description
  • Visual Representation: Figure 14 likely presents a series of scatter plots. Each scatter plot compares the prevalence of occupational categories as determined by direct assignment and cluster-based approaches at a specific aggregation level. The x-axis represents the prevalence (percentage) of an occupational category as determined by the direct assignment method, and the y-axis represents the prevalence of the same occupational category as determined by the cluster-based approach.
  • Direct Assignment vs. Cluster-Based: The 'direct assignment' method refers to the primary method used in the study, where individual conversations are directly classified into occupational categories based on their content. The 'cluster-based approach' is a secondary method used to validate the primary method, where conversations are first grouped into clusters, and then the clusters are assigned to occupational categories.
  • Aggregation Levels: The 'aggregation levels' refer to different levels of granularity in the cluster-based approach. At higher aggregation levels, more conversations are grouped into each cluster, resulting in a less detailed representation of the data. The caption does not specify what statistical measure is used to compare direct assignment and cluster-based approaches.
Scientific Validity
  • Robustness Assessment: Comparing the results of direct assignment and cluster-based approaches is a valuable method for assessing the robustness and validity of the study's findings. If the two methods yield similar results, this increases confidence that the observed patterns are not simply artifacts of the specific method used.
  • Clustering Method: The scientific validity of the figure depends on the appropriateness of the methods used to generate the clusters and assign them to occupational categories. The clustering algorithm and the criteria used to evaluate the quality of the clusters should be clearly described in the methodology section. The scientific validity could be strengthened by assessing the correlation.
  • Method Limitations: It is important to consider the potential limitations of both the direct assignment and cluster-based approaches. The direct assignment method may be subject to bias due to the subjectivity of human coders or the limitations of automated classification algorithms. The cluster-based approach may be sensitive to the choice of clustering parameters and the method used to assign clusters to occupational categories.
Communication
  • Clarity and Purpose: The caption clearly states the purpose of Figure 14: to compare the prevalence of occupational categories as determined by two different methods: direct assignment and cluster-based approaches. It also mentions that the comparison is made across various aggregation levels, which is a key element of the analysis.
  • Accessibility: While the caption is informative, it lacks context for readers who are not already familiar with the 'direct assignment' and 'cluster-based approaches' mentioned. A brief explanation of what these methods entail would improve accessibility.

First Reference in Text
Figure 15 shows how category prevalence varies across all aggregation levels, while Figure 16 presents the correlation metrics alongside mean squared error measurements.
Description
  • Visual Representation: Figure 15 likely presents a series of bar charts. Each set of bars would represent an occupational category. Each bar within a set represents the prevalence of the occupational category as determined by a specific method (direct assignment or cluster-based) at a specific aggregation level. The aggregation level is defined by the cluster size.
  • Direct Assignment vs. Cluster-Based: The 'direct assignment' method refers to assigning conversations directly to occupational categories based on their content. The 'cluster-based' approach involves first grouping conversations into clusters based on similarity and then assigning the clusters to occupational categories. The point is to see how the prevalence changes as we change the cluster size.
  • Comparison of Prevalence: The figure allows for a comparison of how the prevalence of different occupational categories changes as the aggregation level varies. This is important for understanding the sensitivity of the results to the choice of aggregation level and for identifying potential biases or artifacts that may arise from different methodological choices.
Scientific Validity
  • Robustness Assessment: The figure provides valuable information about the robustness of the study's findings to different methodological choices. By comparing the prevalence of occupational categories across different aggregation levels, the researchers can assess whether the observed patterns are consistent and reliable.
  • Clustering Method: The scientific validity of the figure depends on the appropriateness of the methods used to generate the clusters and assign them to occupational categories. The clustering algorithm and the criteria used to evaluate the quality of the clusters should be clearly described in the methodology section.
  • Potential Biases: It is important to consider the potential for bias in both the direct assignment and cluster-based approaches. The direct assignment method may be subject to bias due to the subjectivity of human coders or the limitations of automated classification algorithms. The cluster-based approach may be sensitive to the choice of clustering parameters and the method used to assign clusters to occupational categories.
Communication
  • Clarity and Purpose: The caption clearly identifies the figure's purpose: to show how the prevalence of different occupational categories varies across different aggregation levels when using direct assignment versus cluster-based assignment. This provides a valuable insight into the stability of the results across different methodological choices.
  • Accessibility: While the caption is informative for a scientific audience, it might benefit from a brief explanation of what 'prevalence of occupational categories' specifically refers to. Is it the percentage of conversations, user accounts, or something else? This would improve the caption's accessibility for a broader audience.

Figure 16: Comparison of occupational category distributions between direct assignment and cluster-based approaches at various aggregation levels, evaluated using different correlation metrics (Pearson, Kendall, Spearman) and Mean Square Error (MSE). These metrics provide complementary views of how well the cluster-based categorization aligns with analysis on conversations directly.
First Reference in Text
Figure 15 shows how category prevalence varies across all aggregation levels, while Figure 16 presents the correlation metrics alongside mean squared error measurements.
Description
  • Visual Representation: Figure 16 likely presents a series of plots showing how different correlation metrics and the Mean Squared Error (MSE) vary with the aggregation level. The x-axis of each plot likely represents the aggregation level (e.g., cluster size), and the y-axis represents the value of the corresponding metric (correlation coefficient or MSE).
  • Occupational Category Distributions: The 'occupational category distributions' refer to the relative frequencies of different occupational categories in the dataset. These distributions are obtained using two different methods: 'direct assignment' and 'cluster-based approaches'. These methods are then compared using statistical metrics.
  • Correlation Metrics and MSE: The correlation metrics (Pearson, Kendall, Spearman) are statistical measures of the linear association between two variables. In this case, they measure the degree to which the occupational category distributions obtained through direct assignment and cluster-based approaches are correlated. A higher correlation coefficient indicates a stronger agreement between the two methods. Mean Squared Error (MSE) represents the average squared difference between direct assignment and cluster-based approaches.
Scientific Validity
  • Rigorous Evaluation: The figure provides a rigorous evaluation of the alignment between two different methods for categorizing conversations, using a variety of statistical metrics. This approach enhances the credibility of the study's findings by demonstrating the robustness of the results to different methodological choices.
  • Choice of Metrics: The use of different correlation metrics (Pearson, Kendall, Spearman) is appropriate for capturing different aspects of the relationship between the two distributions. Pearson's correlation measures the linear association, while Kendall's correlation measures the ordinal association. The use of MSE provides a complementary measure of the overall difference between the distributions.
  • Metric Interpretation: The scientific validity of the figure depends on the appropriate application and interpretation of the statistical metrics. The researchers should clearly justify the choice of metrics and discuss any limitations or assumptions associated with their use. Also, it is important to consider the number of data points used in each correlation and whether this number is sufficient to provide stable estimates of the correlation coefficients.
Communication
  • Clarity and Comprehensiveness: The caption clearly and comprehensively describes the figure's purpose: to compare occupational category distributions obtained through direct assignment and cluster-based approaches. It explicitly mentions the use of different correlation metrics (Pearson, Kendall, Spearman) and Mean Square Error (MSE) to evaluate the alignment between the two methods.
  • Nuanced Interpretation: By stating that these metrics provide 'complementary views' of alignment, the caption prepares the reader for a nuanced interpretation of the results, suggesting that no single metric is sufficient to fully capture the relationship between the two categorization methods.
  • Accessibility: While the caption is informative for a scientific audience, it assumes familiarity with correlation metrics and Mean Square Error. A brief, intuitive explanation of these concepts would improve accessibility for readers with less statistical background.

Figure 17: Comparison between the prevalence of occupations when determined via direct assignment compared to clusters at various aggregation levels.
First Reference in Text
We visualize these relationships in several ways. Figure 17 directly compares the prevalence of occupations between direct assignment and cluster-based approaches at different aggregation levels.
Description
  • Visual Representation: Figure 17 likely presents a series of scatter plots, each comparing the prevalence of occupations as determined via direct assignment versus cluster-based approaches at a specific aggregation level. Each point on the scatter plot represents a different occupation. The x-coordinate represents the prevalence of the occupation using direct assignment, and the y-coordinate represents the prevalence of the same occupation using the cluster-based approach.
  • Direct Assignment vs. Cluster-Based: The 'direct assignment' method refers to assigning conversations directly to occupational categories based on their content. The 'cluster-based approach' involves first grouping conversations into clusters based on similarity and then assigning the clusters to occupational categories. The purpose of the figure is to assess the validity of the cluster-based approach by comparing it to the direct assignment method.
  • Aggregation Levels: The 'aggregation levels' refer to different levels of granularity in the cluster-based approach. Higher aggregation levels mean that more conversations are grouped into each cluster, resulting in a less detailed representation of the data. The figure likely shows a series of scatter plots, each corresponding to a different aggregation level, to assess how the agreement between the two methods changes with the aggregation level.
Scientific Validity
  • Robustness Assessment: The figure provides a valuable assessment of the validity and robustness of the study's findings by comparing the results obtained using different methodologies.

Figure 18: Prevalence of top occupations when determined via direct assignment compared to clusters at various aggregation levels.
First Reference in Text
Figure 18 shows how occupation prevalence varies across all aggregation levels, while Figure 19 presents the correlation metrics alongside mean squared error measurements.
Description
  • Visual Representation: Figure 18 likely presents a series of horizontal bar charts. Each bar chart compares the prevalence of the 'top occupations' using direct assignment and cluster-based approaches at a specific aggregation level. The x-axis represents the prevalence of occupations in the data, and the y-axis lists the top occupations.
  • Methodologies Compared: The 'direct assignment' method refers to the primary method of assigning conversations directly to occupational categories. The 'cluster-based' approach involves grouping conversations into clusters and then assigning the clusters to occupational categories. These alternative methods are compared at different aggregation levels to measure the robustness of the approach.
  • Aggregation Levels: The 'aggregation levels' indicate the size of the conversation clusters (e.g., cluster sizes of 50, 100, 250). Higher aggregation levels mean larger clusters and less granularity. By comparing results across different aggregation levels, the researchers can assess the sensitivity of their findings to the choice of clustering parameters.
Scientific Validity
  • Robustness Assessment: The figure provides a valuable assessment of the robustness of the study's findings by comparing the prevalence of top occupations across different methodological choices and aggregation levels. This helps to address potential concerns about bias or artifacts in the data analysis.
  • Clustering Validity: The scientific validity of the figure depends on the rigor of the clustering method. It's important to specify the clustering algorithm used, the criteria for determining cluster similarity, and any steps taken to validate the resulting clusters. It would be helpful to know how the occupations were assigned to clusters.
  • Selection Bias: The selection of 'top occupations' may introduce a bias. It's important to justify the criteria used for selecting these occupations and to consider the potential impact of this selection on the overall results. The results may be skewed based on which occupations were selected.
Communication
  • Clarity and Purpose: The caption accurately describes the figure's purpose: to compare the prevalence of top occupations as determined by direct assignment and cluster-based approaches across varying aggregation levels. It clearly conveys that the figure examines the consistency of occupation prevalence across different methodological choices.
  • Selection Criteria: The phrase 'top occupations' implies a selection process. The caption could be improved by briefly mentioning the criteria used to determine which occupations were considered 'top' (e.g., highest overall prevalence, highest usage, etc.). This would provide valuable context for interpreting the figure.

The figure likely shows how the correlation metrics and MSE change as the aggregation level varies, providing insights into the sensitivity of the results to the choice of clustering parameters.
  • Correlation Metrics and MSE: The Pearson correlation coefficient measures the linear relationship between two variables. Kendall's tau measures the ordinal association between two variables. Spearman's rank correlation coefficient measures the monotonic relationship between two variables. Mean Squared Error (MSE) measures the average squared difference between two sets of values. These metrics give an overall view of the agreement between direct and cluster-based assignment.
Scientific Validity
  • Rigorous Assessment: The figure presents a valuable and rigorous assessment of the validity of the cluster-based approach by comparing it to the direct assignment method using multiple statistical metrics. This strengthens the confidence in the study's findings by demonstrating the robustness of the results to different methodological choices.
  • Metric Selection: The choice of correlation metrics (Pearson, Kendall, and Spearman) is appropriate for capturing different aspects of the relationship between the two distributions. The use of MSE provides a complementary measure of the overall difference between the distributions.
  • Metric Interpretation: The scientific validity of the figure depends on the correct application and interpretation of the statistical metrics. It is essential to ensure that the assumptions underlying each metric are met and that the results are interpreted in the context of the specific research question.

Figure 20: Comparison of median salary by task usage between direct assignment and clusters of size ~1,500. In both cases, task usage is highest for occupations with a median salary between $50,000 and $125,000.
First Reference in Text
Figure 20 shows the difference in usage by median salary between direct assignment and cluster assignment.
Description
  • Visual Representation: Figure 20 likely presents two scatter plots, or potentially overlapping scatter plots, comparing median salary to task usage. One scatter plot shows the results for the direct assignment method, and the other shows the results for the cluster-based approach with a cluster size of approximately 1,500. The x-axis represents the median salary of occupations, and the y-axis represents task usage.
  • Direct Assignment vs. Cluster-Based: The 'direct assignment' method refers to the primary method used to classify conversations directly into occupational categories and tasks. The 'cluster-based' approach is a secondary method used to validate the primary method, where conversations are first grouped into clusters, and then the clusters are assigned to occupational categories and tasks.
  • Key Finding: The key finding is that task usage is highest for occupations with a median salary between $50,000 and $125,000 in both the direct assignment and cluster-based approaches. This suggests that there is a relationship between income and AI adoption in this range.
Scientific Validity
  • Relationship Assessment: The figure provides a valuable assessment of the relationship between median salary and task usage, providing insights into the economic factors that may influence AI adoption. The use of both direct assignment and cluster-based approaches strengthens the validity of the findings.
  • Data Accuracy: The scientific validity of the figure depends on the accuracy and reliability of the median salary data and the task usage measurements. The researchers should clearly describe the sources of these data and any steps taken to ensure their quality.
  • Confounding Factors: It is important to consider the potential for confounding factors that may influence the observed relationship between median salary and task usage. Other factors, such as the nature of the tasks performed in different occupations and the availability of AI tools for those tasks, may also play a role. Also, it is important to establish the statistical significance of the relationship.
Communication
  • Clarity and Summary: The caption clearly summarizes the figure's purpose: to compare the relationship between median salary and task usage, as measured by both direct assignment and cluster-based approaches. It also highlights the key finding: task usage peaks for occupations with a median salary between $50,000 and $125,000.
  • Specific Details: The caption specifies that the cluster size is ~1,500. This is helpful for understanding the level of aggregation used in the cluster-based approach. The use of a salary range ($50,000 to $125,000) provides a concise way to communicate the peak usage range.
  • Accessibility: While the caption is informative for a scientific audience, it assumes familiarity with the terms 'direct assignment' and 'cluster-based approaches'. A brief explanation of these methods would improve accessibility for readers with less background knowledge.

Figure 21: Number of occupations recovered at each aggregation level compared to direct assignment.
First Reference in Text
Figure 21 illustrates this pattern, showing which occupations were identified by each method and where these sets overlap.
Description
  • Visual Representation: Figure 21 likely presents a bar chart or a similar visual representation, displaying the number of unique occupations identified at each aggregation level. The x-axis likely represents the aggregation level, and the y-axis represents the number of unique occupations. There will be a bar for the direct assignment method, and other bars for cluster-based approaches at different aggregation levels.
  • Methodologies Compared: The 'direct assignment' method refers to the primary method used to classify conversations directly into occupational categories. The 'aggregation level' refers to the cluster size used in the cluster-based approach. Higher aggregation levels mean larger clusters and less granular data.
  • Comparison of Occupations: The figure is designed to show the extent to which the cluster-based method identifies the same occupations as the direct assignment method. If the cluster-based method identifies fewer occupations than the direct assignment method, it suggests that the clustering process may be losing information or combining distinct occupations into broader categories.
Scientific Validity
  • Assessment of Recovery: The figure provides a useful assessment of the ability of the cluster-based approach to recover the occupations identified by the direct assignment method. This is important for understanding the limitations of the cluster-based approach and for determining the appropriate level of aggregation to use in the analysis.
  • Methodological Validity: The scientific validity of the figure depends on the accuracy and reliability of the methods used to assign conversations to occupational categories and to generate the clusters. The criteria used to define an occupation as 'recovered' should be clearly specified. There needs to be a clear definition of what is considered a 'recovered' occupation.
  • Potential Biases: It is important to consider potential biases in the direct assignment method, which may lead to an overestimation of the number of unique occupations. It is also important to consider the potential for the cluster-based approach to identify new or emerging occupations that are not captured by the direct assignment method.
Communication
  • Clarity and Purpose: The caption clearly states the figure's purpose: to show how the number of occupations identified varies across different aggregation levels when compared to the direct assignment method. This indicates that the figure is used to assess how well the cluster-based assignment recovers the occupations identified by the direct assignment method.
  • Accessibility: The caption is concise and avoids unnecessary jargon, making it relatively accessible. However, readers unfamiliar with the study's methodology might benefit from a brief explanation of what 'recovered' means in this context (e.g., identified as having significant AI usage).

First Reference in Text
We visualize these relationships in several ways. Figure 22 directly compares the prevalence of tasks between direct assignment and cluster-based approaches at different aggregation levels.
Description
  • Visual Representation: Figure 22 likely presents a series of scatter plots, with each plot comparing task prevalence determined via direct assignment versus the cluster-based approach at a given aggregation level. The x-axis represents task prevalence (percentage) using the direct assignment method, and the y-axis represents task prevalence using the cluster-based method.
  • Methodologies Compared: The 'direct assignment' method refers to assigning conversations directly to specific tasks based on their content. The 'cluster-based' approach involves grouping conversations into clusters based on similarity and then assigning the clusters to tasks. This is a comparison of these two methods.
  • Aggregation Levels: The 'aggregation levels' refer to the cluster size used in the cluster-based approach. Higher aggregation levels mean larger clusters and less granular data. The figure will show how the agreement between the two methods changes as the aggregation level varies.
Scientific Validity
  • Robustness Assessment: The figure provides a valuable assessment of the robustness of the study's findings to different methodological choices. If the direct assignment and cluster-based approaches yield similar results for task prevalence, this increases confidence in the reliability of the findings.
  • Methodological Validity: The scientific validity of the figure depends on the accuracy and reliability of both the direct assignment and cluster-based methods. It is important to ensure that the task classifications are consistent and that the clustering algorithm is appropriate for the data.
  • Potential Biases: It is important to consider the potential for bias in both the direct assignment and cluster-based approaches. The direct assignment method may be subject to bias due to the subjectivity of human coders or the limitations of automated classification algorithms. The cluster-based approach may be sensitive to the choice of clustering parameters and the method used to assign clusters to tasks.
Communication
  • Clarity and Purpose: The caption clearly states the figure's purpose: to compare the prevalence of tasks as determined by direct assignment and cluster-based approaches at various aggregation levels. This indicates that the figure is used to assess the stability of task prevalence estimates across different methodologies.
  • Accessibility: While the caption is concise and informative for a scientific audience, it could benefit from a brief reminder of the roles of 'direct assignment' and 'cluster-based' approaches in the overall analysis. This would improve accessibility for readers who may have forgotten the details of these methods.

Figure 23: Prevalence of top tasks when determined via direct assignment compared to clusters at various aggregation levels.
First Reference in Text
Figure 23 shows how task prevalence varies across all aggregation levels, while Figure 24 presents the correlation metrics alongside mean squared error measurements.
Description
  • Visual Representation: Figure 23 likely presents a series of horizontal bar charts. Each chart compares the prevalence of tasks derived from direct assignment with prevalence of tasks derived from cluster-based assignment, at various aggregation levels. The x-axis represents the prevalence of a task, and the y-axis represents the top tasks.
  • Assignment Methods: The 'direct assignment' method refers to classifying a conversation directly to tasks. In contrast, 'cluster-based' assignment first groups conversations into clusters, and then assigns each cluster to tasks. This comparison is performed for 'top tasks', which are the tasks that have the highest prevalence of AI usage.
  • Aggregation Levels: The 'aggregation levels' refer to the different granularities of the cluster-based approach, and these likely correspond to the number of conversations in a cluster. As the number of conversations in a cluster increases, the number of tasks likely decreases.
Scientific Validity
  • Robustness: The figure provides a useful comparison of task prevalence across different methodologies, and this is important for assessing how sensitive the results are to the choice of methodology. This helps to ensure that the findings are not simply artifacts of the data analysis techniques.
  • Methodological Validity: The scientific validity of the figure rests on the appropriateness of the methods used to assign tasks. This includes both direct assignment and cluster-based assignment. The clustering algorithm should be specified and justified. The criteria used to define a task as 'prevalent' or 'top' must be justified.
  • Potential Bias: The choice of 'top tasks' could introduce bias. The researchers should clearly justify the criteria used for selecting these tasks and acknowledge any potential limitations. A wider range of tasks should be considered to confirm results.
Communication
  • Clarity and Purpose: The caption clearly indicates the figure's purpose: to compare the prevalence of 'top tasks' as determined by two methods (direct assignment and cluster-based) across different aggregation levels. This sets the expectation that the figure will show a comparison of task prevalence based on different methodological choices.
  • Accessibility: While the caption is concise, it lacks information about how 'top tasks' were selected. Specifying the selection criteria (e.g., tasks with the highest overall prevalence) would enhance the caption's informativeness. Also, readers unfamiliar with the terms 'direct assignment' and 'cluster-based' might find a brief explanation beneficial.

The x-axis of each plot likely represents the aggregation level, and the y-axis represents the value of the corresponding metric.
  • Task Distributions: The 'task distributions' refer to how conversations are classified into the base-level tasks defined in the O*NET database. The goal is to see how the task distributions are affected by different approaches.
  • Assignment Methods: The 'direct assignment' method refers to the primary method used to classify conversations directly into tasks, while the 'cluster-based approaches' represent an alternative approach. The figure is designed to show the extent to which the cluster-based assignments agree with the direct assignments.
  • Statistical Metrics: The Pearson correlation coefficient measures the linear relationship between two variables. Kendall's tau measures the ordinal association between two variables. Spearman's rank correlation coefficient measures the monotonic relationship between two variables. Mean Squared Error (MSE) measures the average squared difference between two sets of values.
Scientific Validity
  • Assessment of Alignment: The figure provides a valuable assessment of the alignment between two different methods for classifying conversations into tasks. The use of different correlation metrics and MSE provides a comprehensive evaluation of the agreement between the two approaches.
  • Statistical Validity: The scientific validity of the figure depends on the appropriate application and interpretation of the statistical metrics. It is important to ensure that the assumptions underlying each metric are met and that the results are interpreted in the context of the specific research question. The statistical power of the analysis should also be considered.
  • Potential Biases: It is important to consider the potential for bias in both the direct assignment and cluster-based approaches. It is also important to consider that each of the statistical metrics have their own strengths and weaknesses.
Communication
  • Clarity and Scope: The caption clearly outlines the figure's purpose: comparing task distributions from direct assignment and cluster-based methods. It also highlights the use of correlation metrics and MSE, emphasizing the comprehensive approach to evaluating the alignment between the two methodologies.
  • Accessibility: The caption could be improved by briefly stating what 'task distributions' represent in the context of the study. Is it the overall prevalence of certain tasks, the relationship between tasks, or something else? This would make it easier for readers to understand the figure's main message.

Description
  • Visual Representation: Figure 25 most likely presents a bar chart. The x-axis probably represents the aggregation level used in the cluster-based approach. The y-axis represents the number of occupations. There are two sets of bars: one showing the occupations found through the direct assignment method, and one or more showing the occupations found through the cluster-based method. The height of the bars indicates the number of occupations identified by each method at each aggregation level.
  • Methods Compared: The 'direct assignment' method refers to the baseline against which the cluster-based approach is being evaluated. This method assigns conversations directly to an occupation. 'Aggregation level' refers to the size or number of conversations that are grouped together into a cluster. A higher level would mean that more conversations are grouped together.
  • Assessment of Recovery: The figure assesses how well the cluster-based method can reproduce the occupations identified by the direct assignment method. In other words, it shows whether the cluster-based analysis can 'recover' the same occupations that were identified using the direct assignment method.
Scientific Validity
  • Importance of Figure: This figure is important for understanding the limitations of the cluster-based approach. By quantifying the number of occupations recovered at each aggregation level, the researchers can assess the trade-off between computational efficiency and accuracy. This assessment is critical for selecting the appropriate aggregation level for the analysis.
  • Methodological Accuracy: The scientific validity of the figure depends on the accuracy of the methods used to assign conversations to occupations in both the direct assignment and cluster-based approaches. It's important to account for false positives and false negatives in each method.
  • Recovery Criteria: The criteria for determining whether an occupation is 'recovered' at each aggregation level should be clearly defined. For example, is there a minimum percentage of conversations that must be assigned to a given occupation for it to be considered 'recovered'? The sensitivity of the results to these criteria should also be assessed.
Communication
  • Clarity and Conciseness: The caption is reasonably clear in stating that the figure compares the number of occupations 'recovered' by the cluster-based method at various aggregation levels to those identified by the direct assignment method. However, the term 'recovered' needs further clarification for those unfamiliar with the validation process.
  • Accessibility: To enhance accessibility, the caption could briefly explain what 'recovered' means in this context: e.g., occupations that the cluster-based method also identifies as having significant AI usage, consistent with the direct assignment method. This could be in the form of a parenthetical.

Description
  • Visual Representation: Figure 26 likely presents a set of bar charts or a line graph showing the relationship between aggregation level and the average number of tasks assigned to the top occupations. The x-axis likely represents the aggregation level (e.g., cluster size), and the y-axis represents the average number of tasks assigned to the top occupations.
  • Key Variables: The 'top occupations' are a subset of occupations selected based on some criteria (e.g., highest AI usage). The 'number of tasks assigned' refers to the number of tasks from the O*NET database that are associated with a given occupation, based on the conversation data.
  • Aggregation Levels: The 'aggregation level' refers to the cluster size used in the cluster-based method. Higher aggregation levels mean larger clusters and less granularity. The expectation that higher aggregation levels will result in fewer average tasks per occupation reflects the fact that larger clusters are likely to encompass a broader range of tasks, diluting the association between specific occupations and specific tasks.
Scientific Validity
  • Impact of Aggregation: The figure provides a valuable assessment of the impact of aggregation level on the number of tasks assigned to occupations. This is important for understanding the sensitivity of the analysis to the choice of clustering parameters.
  • Methodological Validity: The scientific validity of the figure depends on the appropriateness of the methods used to assign tasks to occupations and to generate the clusters. The criteria used to define an occupation as 'top' must be justified. The method needs to account for tasks that may be present in multiple occupations.
  • Potential Bias: It is important to consider the potential for bias in the selection of 'top occupations'. The researchers should clearly justify the criteria used for selecting these occupations and acknowledge any potential limitations. The analysis should also consider the statistical significance of the observed trend.
Communication
  • Clarity and Purpose: The caption clearly conveys the figure's purpose: to show how the number of tasks assigned to 'top occupations' changes with different aggregation levels. It also states the expected trend: that higher aggregation levels result in fewer average tasks per occupation.
  • Context and Rationale: The phrase 'As expected' suggests that this trend is theoretically justified or consistent with prior findings. It would be helpful to briefly explain why this trend is expected. Also, there is no mention of how these 'top occupations' were determined.
  • Accessibility: For a scientific audience, the level of detail is probably sufficient. However, a brief explanation of how tasks were assigned to occupations would be valuable for a broader audience.
