The Structure of Scientific Revolutions

I watched two colleagues look at identical data and see different problems entirely. One saw resource allocation failure, the other incentive misalignment. Same spreadsheet, different worlds.

Kuhn maps how this happens. Paradigms shape perception itself—we literally see different phenomena when working within different frameworks. The book traces how crises unfold: anomalies accumulate, ad hoc fixes proliferate, competing schools fragment consensus. The structure becomes visible once you see it—in climate science debates, AI ethics controversies, organizational theory conflicts. The question becomes: what framework makes this phenomenon visible at all?

Kuhn argues that science progresses through revolutionary transformations of entire conceptual frameworks. What we call "normal science" is puzzle-solving within an established paradigm—an accepted set of methods, problems, and standards. Scientists assume the paradigm is correct and work to extend its application. But anomalies accumulate. Some puzzles resist solution. Eventually, confidence in the paradigm erodes, crisis develops, and a new framework emerges that is incommensurable with the old. The shift from Newtonian physics to Einstein's relativity meant seeing a different world.

The book's deepest contribution is showing that paradigms are inescapable. We cannot do science from a neutral vantage point. Every observation is theory-laden; every question presupposes a framework. Kuhn compared paradigm shifts to gestalt switches—you see either the duck or the rabbit, never both simultaneously. Scientists working in different paradigms work in fundamentally different conceptual universes. This doesn't mean science is irrational, but it does mean rationality itself operates within frameworks.
