Illusory Pattern Perception Drives Spurious Inference in Large Language Models

Peihua Mai, Zhuoyan Shao, Xinbao Qiao +3

Illusory pattern perception is a well-documented human cognitive tendency to infer meaningful relationships in data that is actually random. Such a tendency, often described as "co…
