AI Summary

This study investigates the effectiveness of a brief generative AI literacy training on the ability of intelligence analysts to distinguish real from AI-generated images. Through a counterbalanced within-subject randomized experiment involving 32 analysts and 2,544 image judgments, the researchers found that a 30-minute training significantly improved overall accuracy by 9 percentage points, primarily driven by a 14.2 percentage point increase in correctly identifying real images.

Abstract

Across social and online platforms, people are increasingly exposed to AI-generated images. As a consequence, the task of distinguishing AI-generated from authentic images is becoming a central challenge for information ecosystems. While humans perform better than chance, accuracy falls short of many operational needs. Initial evidence shows that visually oriented training can improve deepfake detection but does not improve participants' ability to identify real images as real. Here, we investigate the efficacy of a brief training intervention for intelligence analysts employed by the United States government in 2024. We conducted a counterbalanced within-subject randomized experiment in which we showed participants real and AI-generated images varying in pose complexity and scene context and asked them whether each image was real or AI-generated, both before and after an expert delivered a 30-minute training that pointed out patterns in seven real and 50 AI-generated images. We collected 2,544 image-level judgments from 32 intelligence analysts. We find training increased overall accuracy by 9 percentage points (95% CI: [2.7, 15.4]) from a baseline of 72%. We find the improvement is driven by a 14.2 percentage point increase in accuracy for real images (95% CI: [0.7, 27.7]). Through a careful experimental setup that curated matched pairs of real and AI-generated images across pose complexity categories, we reveal how these trainings influence people with different levels of digital forensics and generative AI experience and identify the kind of image-based content where this training intervention appears to be most effective. Ultimately, these results provide causal evidence that a brief, structured training can improve human judgment across a diverse array of real and AI-generated images, informing organizational responses to AI-generated visual misinformation.


Key findings
The training increased overall accuracy by 9 percentage points (from a 72% baseline) and significantly improved the identification of real images by 14.2 percentage points, reducing false-positive errors without simply increasing skepticism. The training effects extended broadly across various image types, with the largest gains observed for portrait stimuli, and were effective across different levels of digital forensics experience and generative AI familiarity among the analysts.
Approach
The study conducted a randomized, counterbalanced within-subject experiment with 32 intelligence analysts. Participants judged images as real or AI-generated before and after receiving a 30-minute expert-delivered training on AI-generated image artifacts. The training utilized 50 AI-generated images and 7 real images to illustrate patterns of generative AI 'tells' and 'incapabilities'.
Datasets
A dataset of 149 verified real photographs and 450 photorealistic AI-generated images (used in previous research by Kamali et al. 2025) was used. For this experiment, a stimulus set of 97 images was curated, balanced for authenticity (50 real, 50 AI-generated, adjusted to 47 real and 50 AI-generated due to technical difficulties), scene complexity, and image-to-text descriptions from contemporary diffusion models like Midjourney, Adobe Firefly, and Stable Diffusion.
