AI safety researcher Andrew Critch criticizes groupthink that treats unproven hypotheses as true by inertia, and lists his self-admittedly "relatively dubious" credences: Hodge conjecture 50%, Riemann hypothesis 60%, ZFC consistency 75%, P≠NP 80%, Goldbach 85%, Collatz 90%. His notably low confidence in the Riemann hypothesis and P≠NP stands out against typical expert opinion.
