Error Correction in Science

Error correction in science is not a peripheral activity that happens after the real work is done. It is the real work. A scientific community's capacity to identify, publicize, and retract false claims is more diagnostic of its health than its capacity to generate true ones. True claims are cheap in the short run; the hard problem is building a system that can discard its own falsehoods before they crystallize into consensus.

The mechanisms are social, not merely methodological. Peer review catches some errors before publication. Replication studies catch others after. But the deepest error correction operates through the career structure of science: the incentive to challenge established results, the reward for falsification, and the social norm that changing one's mind in response to evidence is a sign of competence rather than weakness. Where these norms are absent, error accumulates. Where they are present, science functions as a complex adaptive system that corrects its own trajectory.
