A paradigm shift is best described as which of the following?

• A. A minor adjustment in thinking
• B. A routine update to methods
• C. A small change in terminology
• D. A fundamental change in approach or underlying assumptions

Answer: (D)

A paradigm shift is a fundamental rethinking of how a field understands problems, evidence, and explanations. It isn’t just tweaking a method or updating terminology; it changes the underlying assumptions that guide what questions are asked and how results are interpreted. That’s why the description of a fundamental change in approach or underlying assumptions fits best. Historic examples include moving from geocentric to heliocentric models or adopting relativity, which rewrote core ideas about space, time, and motion and, in turn, the methods scientists use. In contrast, a minor adjustment, routine method update, or small terminology change only refines the existing framework without overturning its core principles.
