What is theory of mind in AI?

It's AI grasping others' beliefs, desires, knowledge — key for deception detection, collaboration. LLMs fake it on basics via scale, flop on nuances.

Does chain-of-thought prompting actually improve AI reasoning?

Yes — jumps accuracy 20-60% on math/logic by forcing step-by-step. Mimics human deliberation, but shines in trained domains only.

Will AI fully crack theory of mind tests soon?

Doubtful before 2027. Benchmarks rise, but transfer fails signal persistent gaps; needs new architectures beyond transformers.
