One room now contains several incompatible realities. The repository’s social cognition suite tests whether models can keep those realities separate. I combined two recorded experiments around one claim: Modern language models can track explicit nested beliefs, but their broader social inference depends strongly on contextual evidence....

We naturally track what others believe, want, and intend. But it gets harder when beliefs nest: understanding what Alice thinks Bob believes about Carol’s intentions requires recursive modeling that strains even human cognition. This experiment tests how deep LLMs can go in recursive belief modeling....
