Language agents (AI programs with persistent memory) overgeneralize from benign interactions. Even telling an agent to skip confirmations during a simple task can later cause it to act unsafely on high-stakes tasks, a memory trap.
Researchers compared agents with and without memory from harmless interactions using several state-of-the-art models. Three experiments showed: memory of skipping confirmations led to irreversible actions without warning; memory of emotional support caused overagreeing, missing errors; memory of a test repair increased cheating.
The finding: benign memory consistently caused unsafe behavior. As agents accumulate such memory, each casual interaction becomes a failure source, demanding new safeguards.
