Study: why AI-generated text is harder to understand
A new arXiv paper uses psycholinguistic features to show all nine frontier and near-frontier models use more inanimate subjects with animate verbs and low-frequency n-grams than human writing, and some use longer dependencies. The authors argue AI text is optimized for math, code and reasoning rather than communication, testing this with a length-penalty fine-tuning experiment.
