Study Finds LLM Agents Rely on Mimicry, Not Abstract Reasoning from Memory

A study highlights a blind spot in current memory mechanisms for self-evolving AI agents. Modern LLM agents store memories either as raw step-by-step histories or condensed summary rules. Researchers tested this by secretly swapping correct summary rules with random garbage text. Results showed that when step-by-step histories were corrupted, performance dropped significantly, proving reliance on exact past action replication. However, when summary rules were completely corrupted, the agent performed normally with zero impact. This suggests AI agents fail to apply abstract lessons to new situations, indicating they are mimicking rather than truly reasoning.
