Like the human brain, LLMs use separate sets of units for language, formal reasoning, social reasoning, and intuitive physical reasoning. A modular organization of cognition may be a fundamental principle of intelligence!

I am so excited about this finding from @pengrui-han.bsky.social and @andreadevarda.bsky.social, also with Jacob Andreas! Perhaps modularity is inevitable in intelligent systems, biological or in silico. :)

The human brain is strikingly modular: distinct networks for language, formal reasoning, social reasoning, physical reasoning. Is this fundamental to intelligent systems, or an accident of evolution? In our new preprint, we find the same modular organization emerges in LLMs.
