Super-recognisers
Can reliably detect AI-generated faces, while typical observers cannot

Via PsyArXiv: "AI-generated faces have become virtually indistinguishable from real human faces. In this study, we demonstrate that super-recognisers—individuals with exceptional face recognition abilities—can reliably detect AI-generated faces, while typical observers cannot. Super-recognisers (N=36) and typical observers (N=89) were shown images of real and AI-generated faces and classified each as real or fake. Super-recognisers performed significantly above chance, with decision confidence positively correlated with accuracy, indicating metacognitive insight. In contrast, typical observers performed at chance level, with no insight into their accuracy. Aggregating responses using a wisdom-of-crowds approach improved super-recogniser accuracy substantially but did not affect typical observer accuracy. To understand the basis of super-recognisers’ enhanced sensitivity to real faces, we examined the facial cues used by each group. Super-recognisers and typical observers showed qualitative differences, with super-recognisers relying less on perceived familiarity and memorability—cues that have previously misled typical observers when assessing face authenticity. These findings suggest that understanding individual differences in face-processing ability may help mitigate risks associated with hyper-realistic AI faces."
