Representing possible alternatives lies at the heart of moral judgment. As LLMs become embedded in our reasoning processes, they change the set of alternatives we bring to mind.

Our #CogSci2026 paper shows that AI might be making us judge people harsher⚖️ https://osf.io/preprints/psyarxiv/uy8sz_v1

We find that LLMs sample option spaces differently from humans, producing higher-valued but more semantically concentrated alternatives. 💭

When people consider action alternatives generated by an LLM, they assign more blame than when they consider human-generated alternatives.
