Conjecture
Evidence alone rarely retires an elite's belief; a cost to holding it does.
The claim
New research alone seldom retires a belief an order's elite holds; the belief gives way when events make holding it costly as well.
Sapiens ch12 (471): after 1945 Western elites dropped racial hierarchy not "simply because new scientific research was published"; the war made it costly. Outside check (web_search 25fcc582, 13 Nov): Barkan, The Retreat of Scientific Racism, finds the move away "prompted as much by political and social factors as by new scientific understanding", so Harari's "far more powerful" is narrowed to "alone ... as well". For us this is the serious objection to "claims anyone can challenge": a challenge that only adds evidence moves little. Our answer is Leo's costly-stance layer: a stance that carries a track record makes holding a refuted claim cost something.
