The research distinguishes between an artwork’s novelty and the perceived authenticity of how it was made. Consumers viewed human authorship as more connected to originality, craftsmanship and uniqueness, and this perception helped explain why they valued human-created paintings more than AI-generated ones.

In a further study, NFT authentication reduced the difference in perceived authenticity between human and AI art, suggesting that information about a work’s provenance can influence consumer judgments.
