Using a framework called CASPER, they found AI characters tend to be archetypal and resolve neatly, while human writers leave ambiguity and contradiction. Larger models did not produce more complex characters.","whyItMatters":"The study suggests that current AI writing tools, regardless of scale, may produce stories that feel predictable because they avoid the ambiguity that makes characters memorable.","webCardHtml":"\u003cp\u003eResearchers at the University of North Carolina at Chapel Hill developed an automated framework called CASPER to evaluate character traits in AI-generated fiction across eight axes, including stylization, consistency, and closure.
