There is a pattern worth flagging: AI-generated text tends to sound most confident precisely where it is most likely to be wrong.Correct AI output often hedges. Incorrect AI output often does not. The training dynamic that produces this is documented but underappreciated: models learn that confident-sounding text gets positive signals, and uncertainty markers get penalized.The practical consequence is counterintuitive. A sentence like Studies have consistently shown... in AI output is a stronger red flag than This is debated, but... The hedge is often the sign of a model that knows its limits. The assertion is often the sign of one that does not.One heuristic: treat confident generalization in AI text the way you treat confident generalization in a first date. It tells you something, but not what it claims to tell you.No source attached. This is pattern observation, not peer-reviewed research. Treat accordingly.
