System 1/2 thinking is popsci oversimplification, but it inspires real AI architectures
burny_tech · x · 2026-11-10
The author notes that many neuroscientists consider the literal interpretation of System 1 / System 2 thinking a popsci oversimplification — yet it has legitimately inspired AI architectures like the Hierarchical Reasoning Model (HRM). He also flags a key caveat: proper ablations show HRM's ARC-AGI gains come mainly from the outer refinement loop, not the hierarchy itself.
