Signal‑Driven Academic Belief Formation

Academics often adopt and propagate doctrines not because of strong empirical support but because beliefs act as social signals (to peers, funders, and employers), creating reinforcement loops that make obviously weak ideas persist within disciplines. This process helps explain historical episodes like denial of animal consciousness, logical positivism, and eugenics spreading through learned cohorts rather than by superior evidence. — If belief formation in universities is driven by signaling and career incentives, reforming hiring, evaluation, and publication incentives could materially improve the quality of public expertise and institutional trust.
