A century of evidence proves it. Thomas Kuhn was a philosopher whose groundbreaking 1962 book, The Structure of Scientific Revolutions, is credited with bringing the term paradigm shift to pop culture. Kuhn described how scientific communities stick to established paradigms, even as evidence of their limitations mounted. Widely accepted paradigms for understanding and interpreting knowledge don’t crumble under the weight of mere data. Instead, they tend to persist until a crisis emerges—when anomalies become so disruptive that a shift to a new paradigm is unavoidable.
