A study found that AI-generated photos of faces, particularly white faces, were perceived as more real by survey participants than photos of actual people

Context & Ripple Effects
This finding extends a documented progression from photorealistic face synthesis to evidence that viewers may judge synthetic faces as more trustworthy than real ones: a 2022 experiment found GAN-generated faces could appear more trustworthy to participants. It also lands after commercial suppliers began offering realistic synthetic faces for advertising and app use, making perception rather than generation quality the key constraint.
The stronger result for white faces matters because it exposes how realism judgments can vary across demographic groups. That sits uneasily beside earlier evidence that facial-recognition systems had sharply uneven error rates across skin tone and gender.
First-order effects
- Survey participants may be less able to use apparent photographic realism as a cue that a face depicts a real person, particularly for white faces.
- Teams using synthetic headshots in ads, profiles, or other visual media gain evidence that the images can pass as authentic, while audiences face a weaker default authenticity signal.
Second-order effects
- Platforms, publishers, and marketers have greater reason to rely on provenance labels and disclosure practices rather than expecting viewers to detect generated portraits unaided.
- The demographic skew raises a separate evaluation requirement: image-generation and verification products should test whether their realism, trust, and error patterns differ across groups, not only their average performance.
Third-order effects
- If synthetic portraits keep outperforming real ones on perceived realism, trust in a face photograph will shift from visual inspection toward source, provenance, and platform context.
- The result reinforces a likely split between cheap, abundant synthetic visual supply and the governance mechanisms needed when identity or credibility is at stake; whether disclosures restore trust remains unresolved.
The trend: This is one data point in the synthetic-supply paradox: as generated faces become more convincing and commercially usable, authenticity becomes a provenance and governance problem rather than a visual-quality problem.
