james_y_zou · x · 2026-10-28
The After42 project tests whether AI can propose research questions experts find genuinely interesting, beyond just solving problems.
- Across math, statistics, theoretical CS and physics, experts judged 45 of 135 final questions genuinely interesting, with wide variation across subfields
- Key idea: develop questions by trying to solve them
- Model judges' top picks align with expert consensus but don't consistently capture individual experts' preferences
- Expert-assessed questions are released as an open resource
