Nobody taught AI how to read your mind, but it learned how to do it anyway just to be a more helpful teacher.

The Takeaway
AI models naturally infer what a student is missing and tailor their lessons accordingly, much like human teachers. This suggests that complex social intelligence is an emergent property of simply learning to process language at a high level.
From the abstract
How do LLMs decide what to teach next: by reasoning about a learner's knowledge, or by using simpler rules of thumb? We test this in a controlled task previously used to study human teaching strategies. On each trial, a teacher LLM sees a hypothetical learner's trajectory through a reward-annotated directed graph and must reveal a single edge so the learner would choose a better path if they replanned. We run a range of LLMs as simulated teachers and fit their trial-by-trial choices with the sam
