Why AI stories feel flat: what the research found

Sixteen studies on how AI fiction differs from human fiction: calmer feelings, tidier endings, and stories that all end up alike.

Why AI stories feel flat: what the research found

About this page

Ask for a story twice, get the same story

In March 2026 Hachette pulled a horror novel called Shy Girl after a detector flagged it as about 78% AI-generated. It was the first commercially published novel cancelled over AI. Around the same time, roughly one in five of 14,000 self-published Amazon novels came back as largely AI-written. So what does give AI fiction away?
