This paper investigates human detection of AI-generated text, finding that "expert" annotators (frequent LLM users) significantly outperform both non-experts and most automatic detectors, achieving 99.3% accuracy compared to the best automatic detector's 98%. The study reveals that experts rely on cues like "AI vocabulary," formulaic structures, and originality, while non-experts perform at chance level. Notably, the majority vote of five experts correctly classified all articles in Experiment 1, even with evasion tactics like paraphrasing. However, humanization, particularly with the 01-PRO model, reduced expert confidence, indicating challenges posed by advanced AI.
The study provides compelling evidence that humans who frequently use LLMs for writing tasks, termed "experts," can effectively detect AI-generated text, outperforming most existing automatic detectors. The research clearly distinguishes between correlation and causation by demonstrating that it is the specific experience with LLMs that leads to this enhanced detection ability, not simply general writing expertise. However, the study does not establish a definitive causal link between specific training methods and improved detection accuracy, as training was not explicitly manipulated.
The practical utility of these findings is substantial. The identification of specific clues used by experts, such as "AI vocabulary" and formulaic structures, offers valuable insights for developing more effective detection methods and training programs. The study also highlights the potential of human-machine collaboration, where human expertise can complement and enhance automated detection systems. These findings are particularly relevant in contexts where the integrity of information is crucial, such as journalism, academia, and online content moderation.
While the study provides clear guidance on the potential of human expertise in detecting AI-generated text, it also acknowledges key uncertainties. The effectiveness of the identified clues may evolve as LLMs become more sophisticated, and the study's focus on American English articles limits the generalizability of the findings to other languages and writing styles. Furthermore, the study primarily focuses on the detection of AI-generated text and does not delve deeply into the ethical implications of increasingly sophisticated evasion techniques.
Several critical questions remain unanswered. For instance, what specific training methods are most effective in enhancing human detection capabilities? How can human-machine collaboration be optimized to maximize detection accuracy and efficiency? Additionally, the study's methodology has limitations that could affect the conclusions. The reliance on self-reported LLM usage to define expertise could introduce bias, and the relatively small sample size of expert annotators limits the generalizability of the findings. Future research should address these limitations by employing more objective measures of expertise, using larger and more diverse samples, and exploring the effectiveness of different training interventions.

Implementation: Elaborate on how the focus on modern LLMs and evasion attempts differentiates this study from previous research, for instance: "Unlike prior studies that primarily examined earlier language models, this research specifically addresses the challenges posed by state-of-the-art LLMs like GPT-4O and Claude-3.5, which exhibit significantly improved text generation capabilities."
This high-impact improvement would significantly enhance reader engagement and provide a clearer roadmap for the paper. The Introduction section should not only introduce the problem and methodology but also offer a glimpse of the main results.
Implementation: Briefly mention the main findings, such as: "Our results demonstrate that individuals who frequently use LLMs for writing tasks exhibit remarkable accuracy in detecting AI-generated text, outperforming existing automatic detection methods."
This medium-impact improvement would enhance the clarity of the introduction by providing a brief definition of "humanization." As this is a key concept in the study, defining it early on will improve reader comprehension.
Implementation: Provide a concise definition of humanization, for example: "Humanization, the process of modifying AI-generated text to make it appear more human-like, is also investigated as a potential evasion tactic."
This low-impact improvement would provide further context for the study's scope. While the focus on non-fiction articles is mentioned, briefly explaining the rationale behind this choice would strengthen the introduction.
Implementation: Add a sentence justifying the focus on non-fiction articles, such as: "We focus on non-fiction articles due to their prevalence in online information dissemination and their susceptibility to manipulation by AI-generated content."

An annotator can highlight texts, make their decision, put confidence, and write an explanation. This AI-generated article was based off of In Alaska, a pilot drops turkeys to rural homes for Thanksgiving, written by Mark Thiessen & Becky Bohrer, was originally published by Associated Press on November 28, 2024.
The section clearly outlines the experimental design, including the task setup, article selection, and annotator details. The use of paired articles and a within-subjects design helps control for confounding variables and increases the study's internal validity.
The use of both TPR and FPR provides a comprehensive evaluation of both human and automatic detectors, allowing for a balanced assessment of their performance.
The section provides a detailed analysis of the differences between expert and nonexpert annotators, including the clues they use and their accuracy rates. This analysis sheds light on the cognitive processes involved in detecting AI-generated text.
The paper clearly defines the two populations of annotators: "experts" and "nonexperts," based on their self-reported use of LLMs for writing-related tasks. This distinction is crucial for understanding the study's findings and their implications.
This low-impact improvement would enhance the clarity of the article selection criteria. While the term "lay audiences" is commonly used, providing a more specific definition within the context of this study would help readers better understand the target audience for the selected articles.
Implementation: Provide a more specific definition of "lay audiences" in the context of this study. For example: "We restrict our study to English nonfiction articles of fewer than 1K words geared towards lay audiences, defined as readers without specialized knowledge in a particular field."
This medium-impact improvement would provide readers with a better understanding of the specific lexical clues that expert annotators use to detect AI-generated text. As "AI vocabulary" is a key finding, elaborating on this concept within this section would strengthen the paper's contribution.
Implementation: Provide a more detailed explanation of "AI vocabulary" and include a few examples. For instance: "Expert annotators identified certain words and phrases commonly used by LLMs, which we term "AI vocabulary." Examples include words like "vibrant," "crucial," and "significantly," as well as phrases like "embark on a journey" and "delve into the intricacies."
This medium-impact improvement would strengthen the study's methodology by providing a clear rationale for the selection of specific LLMs. As the choice of LLMs can significantly impact the results, explaining the reasoning behind these choices would enhance the study's transparency and reproducibility.
Implementation: Briefly explain why GPT-4O and CLAUDE-3.5-SONNET were chosen for Experiments 1 and 2, respectively. For example: "GPT-4O was selected for Experiment 1 as it was the most widely used LLM at the time of the study. CLAUDE-3.5-SONNET was chosen for Experiment 2 to assess the generalizability of expert performance to another state-of-the-art LLM with a significant user base."
This high-impact improvement would enhance the study's external validity by acknowledging and addressing a potential source of bias. While the use of paired articles helps control for content variation, the fact that AI articles are generated based on human-written articles could introduce a bias that favors human detection.
Implementation: Acknowledge the potential bias introduced by generating AI articles based on human-written articles and discuss its implications. For example: "While generating AI articles based on human-written counterparts allows for controlled comparisons, it may also introduce a bias, as the AI models are essentially mimicking the structure and style of human-written articles. This could potentially make it easier for annotators to detect the AI-generated text. Future research could explore using independently generated AI articles to further assess the robustness of human detection capabilities."

Table 2: On average, nonexperts perform similar to random chance at detecting AI-generated text, while experts are highly accurate.
Table 3: Performance of expert humans (top), existing automatic detectors (middle), and our prompt-based detectors (bottom), where each cell displays TPR (FPR). Colors indicate performance bins where darkest teal is best, orange is middling, and purple is worst. We further mark closed-source (7) and open-weights (S) detectors. The majority vote of expert humans ties Pangram Humanizers for highest overall TPR (99.3) without any false positives, while substantially outperforming all other detectors. While the majority vote is extremely reliable, individual annotator performance varies, especially on 01-PRO articles with and without humanization. Prompt-based detectors are unable to match the performance of either expert humans or closed-source detectors.

The section provides a thorough comparison between human experts and automatic detectors, using multiple state-of-the-art detectors and a variety of metrics (TPR, FPR). This allows for a robust evaluation of the relative strengths and weaknesses of each approach.
The coding of expert explanations into specific categories offers valuable insights into the cognitive processes involved in detecting AI-generated text. The use of GPT-40 to assist in this coding process demonstrates a novel and efficient approach to analyzing qualitative data.
The analysis of individual annotator differences, including their accuracy rates, the clues they use, and the errors they make, provides a nuanced understanding of human performance in this task. This analysis highlights the importance of considering individual variation when developing training programs or ensemble methods.
The section presents the results in a clear and organized manner, using tables and figures to effectively communicate the key findings. Table 3, in particular, provides a comprehensive overview of the performance of all detectors across different experiments.
This medium-impact improvement would provide a more balanced perspective on the comparison between human and automatic detectors. While the section highlights the superior performance of human experts, elaborating on the specific limitations of automatic detectors in more detail would further strengthen the paper's contribution to the field.
Implementation: Include a paragraph discussing the limitations of automatic detectors in more detail. For example: "While automatic detectors like Pangram show promising results, they often struggle with text that has been paraphrased or humanized. Furthermore, these detectors are often 'black boxes,' providing limited insight into their decision-making process. This lack of explainability can be a significant drawback in high-stakes applications where understanding the rationale behind a detection is crucial."
This high-impact improvement would enhance the reader's understanding of the coding process and its significance. While Table 4 defines the coding categories, providing more context on how these categories were developed and how they relate to existing literature on AI-generated text detection would strengthen the paper's methodological rigor.
Implementation: Add a paragraph explaining the development of the coding categories. For example: "The coding categories used in this study were developed through an iterative process involving both manual analysis of expert explanations and a review of existing literature on the characteristics of AI-generated text. These categories, such as 'vocabulary,' 'originality,' and 'formality,' reflect both common linguistic features identified in prior work (cite relevant papers) and novel patterns observed in our expert annotations. This comprehensive set of categories allows for a nuanced analysis of the clues that humans use to detect AI-generated text."
This medium-impact improvement would enhance the transparency and trustworthiness of the coding process. Acknowledging potential biases in the coding of explanations, especially since it involves subjective judgment, would strengthen the paper's methodological rigor.
Implementation: Add a sentence or two discussing potential biases in the coding process. For example: "While the use of GPT-40 for coding provides efficiency and consistency, it is important to acknowledge the potential for bias in the coding process. The categories themselves, though developed through careful analysis, reflect the researchers' interpretations of the data. Additionally, the performance of GPT-40 in coding may be influenced by the specific examples used in the prompt. Future research could explore inter-rater reliability with multiple human coders to further validate the coding scheme."
This high-impact improvement would strengthen the paper's practical implications. While the section briefly mentions the implications for training human annotators, providing a more detailed discussion of how the findings could inform the design of specific training programs would enhance the paper's contribution to the field.
Implementation: Expand the discussion of training implications. For example: "The findings of this study have significant implications for the development of training programs aimed at improving human detection of AI-generated text. Specifically, training should focus on enhancing annotators' awareness of the key distinguishing features identified in our analysis, such as 'AI vocabulary,' formulaic sentence structures, and lack of originality. Training modules could incorporate examples of both human-written and AI-generated text, highlighting these features and providing opportunities for practice and feedback. Furthermore, training could address common pitfalls, such as over-reliance on informality as a sign of human writing, as observed in Annotator 3's performance on O1-PRO articles."
Table 4: Taxonomy of clues used by experts to explain their detection decisions. For each category, we report the frequency of explanations that mention that category (regardless of if the annotator was correct) and provide examples of explanations for both human-written and AI-generated articles. While vocabulary and sentence structure form the most frequent clues, more complex phenomena like originality, clarity, formality, and factuality are also distinguishing features.
Figure 3: (Top) A heatmap displaying the frequency with which annotators mentioned specific categories in their explanations when they were correct. Interestingly, vocabulary becomes a less frequent clue for 01-PRO-generated articles, especially with humanization. (Bottom) Same as above, except only computed over explanations when experts were incorrect. Formality is a big source of misdirection for 01-PRO articles, while fixating on sentence structure can lead experts to false positives. Details of each category can be found in Table 4.

The section introduces a novel approach to AI-generated text detection by prompting LLMs with a guidebook derived from human expert explanations. This approach bridges the gap between human and automatic detection methods.
The methodology is clearly described, including the implementation details of the prompt-based detectors and the different prompting strategies used.
The section provides a comprehensive evaluation of the prompt-based detectors, comparing their performance to that of human experts and existing automatic detectors.
The section acknowledges the limitations of the prompt-based detection approach, including its cost, speed, and performance gap compared to human experts.
This high-impact improvement would provide greater insight into the core of the novel methodology. As the guidebook is central to this section's approach, a more detailed explanation of its development would significantly enhance the reader's understanding and the study's reproducibility.
Implementation: Include a more detailed description of the guidebook's development process. For instance: "The guidebook was developed through an iterative process involving expert annotators. Initially, experts provided lists of clues they used for detection. These clues were then analyzed, categorized, and synthesized into a structured guidebook format. The guidebook was further refined based on feedback from experts and preliminary testing with LLMs. It includes sections on vocabulary, grammar, tone, introductions, conclusions, content, contextual accuracy, factuality, creativity, and originality, with specific examples and explanations for each category."
This medium-impact improvement would strengthen the methodological rigor of the study. As prompt engineering can significantly influence the performance of LLMs, providing a more detailed rationale for the specific choices made in designing the prompts would enhance the transparency and reproducibility of the research.
Implementation: Provide a more detailed explanation of the prompt engineering choices. For example: "The prompts were designed to elicit specific reasoning steps from the LLMs, mirroring the analytical process of human experts. Chain-of-thought prompting was employed to encourage the models to articulate their reasoning before providing a final answer. The specific wording of the prompts was iteratively refined based on preliminary experiments to optimize the models' performance."
This high-impact improvement would significantly enhance the paper's contribution to future research directions. While the section briefly mentions fine-tuning, a more thorough discussion of its potential to improve the performance of prompt-based detectors would be highly valuable to the field.
Implementation: Expand the discussion on the potential of fine-tuning. For instance: "While prompt-based detection shows promise, fine-tuning LLMs on a dataset of human expert explanations and annotations could significantly improve their performance. Fine-tuning could enable the models to learn more nuanced patterns and develop a deeper understanding of the features that distinguish human-written from AI-generated text. Future research should explore the effectiveness of different fine-tuning strategies and datasets for this task."
This medium-impact improvement would provide a more balanced perspective on the implications of the research. While the study focuses on the technical aspects of prompt-based detection, discussing the ethical implications of automating the detection process, particularly in relation to potential misuse, would add an important dimension to the paper.
Implementation: Include a brief discussion of the ethical implications. For example: "While automating AI-generated text detection offers potential benefits, it also raises ethical concerns. The development of more sophisticated detection methods could lead to an 'arms race' between detection and evasion techniques, potentially resulting in increasingly sophisticated and deceptive AI-generated content. Furthermore, the automation of detection could have implications for human annotators, potentially displacing human labor in this domain. It is crucial to consider these ethical implications and develop guidelines for responsible development and deployment of automated detection systems."
Table 22: Each cell displays TPR (FPR), with TPR in normal text and FPR in smaller parentheses. Colors indicate performance bins: TPR is darkest teal (100) at best, medium teal (90-99), and burnt orange (89-70). Scores 69 and below are in purple (<70). FPR is darkest teal (0) at best, medium teal (1-5), burnt orange (6-10), and purple (>10) at worst. No percentage signs appear in the cells, but the numeric values represent percentages (e.g., "90" means 90%). We further mark closed-source ( ) and open-weights ( ) detectors.
The section provides a thorough review of relevant literature, covering both human and automatic detection methods, as well as work on evading detection.
The section effectively contextualizes the current study within the broader field, highlighting its novelty and relevance.
The section follows a logical flow, starting with an overview of prior work and then delving into specific areas such as human detection, automatic detection, and evasion techniques.
The section acknowledges the limitations of the current study, which adds to its credibility and provides directions for future research.
This high-impact improvement would strengthen the paper's contribution to future research directions. As human-machine collaboration is a promising area for AI-generated text detection, a more detailed discussion of its potential benefits and challenges would be highly valuable to the field, especially since this section's purpose is to connect the current work to the broader research landscape.
Implementation: Expand the discussion on human-machine collaboration. For example: "Future work could explore how human annotators and automatic detectors can work together synergistically. For instance, automatic detectors could flag potentially AI-generated text, which human experts could then review and analyze in more detail. This collaboration could leverage the strengths of both approaches, combining the speed and scalability of automatic methods with the nuanced judgment and explainability of human experts. Challenges in designing effective human-machine collaborative systems include determining the optimal division of labor, developing interfaces that facilitate seamless interaction, and addressing potential biases that may arise from relying on either human or machine judgments."
This medium-impact improvement would provide a more balanced perspective on the implications of the research. While the study focuses on detection methods, discussing the ethical implications of developing increasingly sophisticated evasion techniques, particularly in relation to potential misuse, would add an important dimension to the paper, especially since this section should address how the work relates to broader societal concerns.
Implementation: Include a brief discussion of the ethical implications of evasion techniques. For example: "The development of increasingly sophisticated humanization techniques raises ethical concerns about the potential for malicious use of AI-generated text. As evasion methods become more effective, it may become increasingly difficult to distinguish between human-written and AI-generated content, potentially leading to the spread of misinformation, the erosion of trust in online information, and other negative societal consequences. It is crucial for researchers and practitioners to consider these ethical implications and work towards developing guidelines and safeguards for the responsible development and deployment of both detection and evasion technologies."
This low-impact improvement would enhance the clarity of the section by providing a more specific timeframe for the "pre-ChatGPT era." As the field of AI-generated text detection has evolved rapidly, specifying the timeframe would help readers better understand the context of the cited prior work. This is particularly relevant for a Related Work section, which should accurately position the current study within the historical development of the field.
Implementation: Provide a more specific timeframe for the "pre-ChatGPT era." For example: "Our study most closely resembles several papers published prior to ChatGPT's release in late 2022. Existing work notes that while naïve annotators do not reliably detect AI-generated texts (Ippolito et al., 2020; Brown et al., 2020; Clark et al., 2021; Karpinska et al., 2021)..."
This medium-impact improvement would provide a more balanced perspective on the comparison between human and automatic detectors. While the section mentions some limitations of automatic detectors, elaborating on these limitations in more detail, particularly in relation to specific challenges posed by advanced LLMs and evasion tactics, would further strengthen the paper's contribution to the field. This aligns with the purpose of a Related Work section, which should critically evaluate existing approaches.
Implementation: Expand the discussion of limitations of automatic detectors. For example: "While automatic detection methods have shown promise, they often struggle with text generated by advanced LLMs, which exhibit more sophisticated language capabilities and can better mimic human writing styles. Furthermore, these detectors are often vulnerable to simple perturbations, such as paraphrasing, and more advanced evasion tactics like humanization. Another limitation is their lack of explainability, as many automatic detectors operate as 'black boxes,' making it difficult to understand the rationale behind their predictions. This lack of transparency can be problematic in high-stakes applications where understanding the basis of a detection is crucial."
The conclusion effectively summarizes the main findings of the study, highlighting the superior performance of expert human annotators in detecting AI-generated text.
The conclusion clearly outlines the implications of the research, particularly for the future of AI-generated text detection and the potential for human-machine collaboration.
The conclusion acknowledges the limitations of the study, which adds to its credibility and provides a balanced perspective on the findings.
The conclusion briefly addresses the ethical considerations of the research, demonstrating an awareness of the broader societal implications of AI-generated text detection.
This high-impact improvement would significantly enhance the paper's contribution to future research directions. As human-machine collaboration is a key takeaway, providing a more detailed discussion of its potential, including specific examples of how this collaboration could work in practice, would be highly valuable for researchers and practitioners in the field.
Implementation: Expand the discussion on human-machine collaboration with specific examples. For instance: "One promising avenue for future research is the development of hybrid systems that combine the strengths of both human and automatic detectors. For example, automatic detectors could be used to flag potentially AI-generated text, which could then be reviewed by expert human annotators. This approach could leverage the speed and scalability of automatic methods while retaining the nuanced judgment and explainability of human experts. Another possibility is the development of interactive tools that allow human annotators to query automatic detectors for specific features or patterns, facilitating a more collaborative and iterative detection process."
This medium-impact improvement would strengthen the paper's practical implications. While the conclusion mentions the potential for training, providing a more concrete discussion of how the findings could inform the design of training programs would be beneficial for those seeking to improve human detection capabilities.
Implementation: Elaborate on the implications for training human annotators. For example: "The findings of this study suggest several avenues for improving the training of human annotators. Training programs could focus on developing annotators' awareness of the specific clues identified in this research, such as 'AI vocabulary,' formulaic sentence structures, and lack of originality. Furthermore, training could incorporate exercises that expose annotators to a wide range of AI-generated text, including examples that have been subjected to evasion tactics like humanization. By providing targeted feedback and practice, such training programs could enhance the accuracy and robustness of human detectors."
This high-impact improvement would provide a more comprehensive perspective on the broader significance of the research. While the conclusion briefly mentions ethical considerations, a more in-depth discussion of the societal implications of increasingly sophisticated AI-generated text and the challenges of detection would significantly enhance the paper's contribution to the field and its relevance to a wider audience.
Implementation: Include a more detailed discussion of the societal implications. For instance: "The increasing sophistication of AI-generated text poses significant challenges to the integrity of information online. The ability to generate realistic and convincing content has implications for the spread of misinformation, the erosion of trust in digital media, and the potential for malicious use in areas such as propaganda and fraud. As AI models continue to improve, the development of robust detection methods, whether human-based, automated, or hybrid, will become increasingly crucial. This research highlights the importance of understanding the capabilities and limitations of both human and automatic detection, and underscores the need for ongoing research and development in this critical area."
This low-impact improvement would reinforce the paper's contribution to the research community. While mentioned in the abstract, briefly reiterating the release of the dataset and code in the conclusion would remind readers of this valuable resource and encourage further research in the area.
Implementation: Add a sentence reiterating the release of the dataset and code. For example: "To facilitate further research in this area, we have released our annotated dataset and code, providing a valuable resource for researchers interested in both human and automated detection of AI-generated text."
