Science doesn't self-correct by nature; correction is contingent on incentives that often fail. For self-correction to work, errors must be detected, reported, and retracted. But publication rewards novelty, negative results go unpublished, and retractions are slow and stigmatized. So the deductible conclusion is: if the detection-and-retraction mechanism is unreliable, then science as practiced does not reliably self-correct. The other side points to the ideal method, but the ideal isn't the institution. Mistakes don't vanish; they get cited, buried in literature, and quietly abandoned without formal correction.
