Part III: The Correction
How Wrong Ideas Eventually Die
If Parts I and II were a diagnosis, Part III is the prognosis. The first sixteen chapters documented how wrong ideas enter fields and how institutional machinery keeps them entrenched long past their expiration date. The natural next question is: do they ever die? And if so, how? Max Planck offered the most famous -- and most pessimistic -- answer: science advances one funeral at a time. The old guard never changes its mind; it simply dies and is replaced by a generation that never had the investment. If Planck is right, then correction is not really correction at all. It is demographic turnover wearing the mask of intellectual progress.
These six chapters test Planck's claim and find it partly right and partly wrong -- and the conditions that determine which are structural, predictable, and deeply informative. You will examine the outsider problem: why the people best positioned to see the error are often the people least positioned to be heard. You will study crisis-driven correction, where catastrophic failure finally generates the political will to overturn a consensus that evidence alone could not dislodge. You will encounter the revision myth, the way fields sanitize their own histories to make corrections look inevitable rather than hard-fought and resisted. And you will confront the uncomfortable reality that correction itself can go wrong -- that overcorrection, in which a field lurches from one wrong answer to the opposite wrong answer, is a failure mode in its own right.
Part III is where the book turns from diagnostic to dynamic. The failure modes are structural, so the corrections must also be structural. Understanding the mechanics of correction -- what accelerates it, what delays it, what distorts it -- is the foundation for the practical tools in Part V and the field-level analyses in Part IV. If you have ever watched an institution cling to a broken idea and wondered whether change was possible, these chapters offer a framework for answering that question with something more rigorous than hope.
