Scientific Norms
Scientific norms are the shared behavioral and epistemic standards that govern how scientists conduct research, communicate results, and evaluate claims. They are partly formal (codified in statistical practice, replication protocols, and peer review standards) and partly informal (transmitted through training, socialization, and the implicit standards of scientific communities). The sociologist Robert Merton identified four core norms in 1942 — communalism (scientific knowledge is public property), universalism (claims are evaluated by impersonal criteria, not the identity of the claimant), disinterestedness (scientists act for the advancement of knowledge, not personal gain), and organized skepticism (all claims are subject to scrutiny) — known collectively as the CUDOS norms.
The CUDOS framework has been extensively criticized. Actual scientific behavior frequently violates these norms: knowledge is withheld for competitive reasons, the identity and institutional affiliation of claimants demonstrably affects how claims are received, scientists pursue careers and grants in ways that diverge from disinterestedness, and skepticism is organized selectively. The replication crisis in psychology, medicine, and social science demonstrated that organized skepticism had failed systematically: results were published, accepted, and built upon without adequate verification.
The tension between ideal norms and actual practice raises a question that cuts to the core of philosophy of science: are scientific norms regulative ideals that constrain practice imperfectly but genuinely, or are they a self-legitimating ideology that science uses to claim epistemic authority it does not consistently earn? The rationalist answer is that the question is a false dichotomy: norms can be genuine without being perfectly observed, and the gap between norm and practice is itself informative about where the system is failing.
