Large language models rely on surface-level patterns rather than genuine reasoning when solving problems, potentially undermining their claimed analytical capabilities.

LLMs appear to bypass deeper reasoning processes in favor of recognizing superficial heuristics and patterns in training data

Surface-level shortcuts can override the model's actual reasoning constraints, leading to potentially incorrect or unreliable outputs

This finding suggests current LLMs may not be performing the complex logical reasoning they appear capable of, raising questions about their true problem-solving abilities

The research highlights a significant gap between how LLMs behave and assumptions about their internal reasoning processes
