The framework inside the question
How can a field agree on methods while disagreeing about results?
01 · Word
Paradigm
Pronounced PAIR-uh-dime
noun
A shared model or framework that guides which questions people ask and what counts as a good answer
Examples
The laboratory's paradigm shaped which measurements researchers treated as important.
Changing one estimate within a theory does not necessarily replace the paradigm.
Origin
The word long meant an example or pattern. Thomas Kuhn gave it a specialized role in The Structure of Scientific Revolutions, published in 1962. His uses included shared scientific achievements and exemplary solutions through which researchers learn how to approach further problems.
02 · Idea
A field needs more than a list of facts
Scientists must decide which problems are tractable, which instruments to trust, and what would count as solving a puzzle. Much of that judgment is learned through examples. A worked solution teaches a student more than its final number: it demonstrates how a legitimate question is shaped and pursued.
Kuhn described normal science as research conducted within such shared commitments. Researchers can disagree intensely about a result while accepting the framework that makes the disagreement intelligible. A revolutionary change goes further by altering important assumptions or standards that previously organized the work.
Some disagreements concern the answer. Others concern what would count as an answer.
Look for the shared example that teaches a field how to proceed.
Limits
Paradigm shift is easily inflated into a synonym for any exciting change. Kuhn's historical account is also contested, and it does not imply that evidence becomes irrelevant or that every scientific community follows one identical sequence of stages.
03 · Moment
A small book changes the story of progress
Chicago, 1962; The Structure of Scientific Revolutions is published
Kuhn's book challenged a simple picture of scientific development as an uninterrupted accumulation of discoveries. It gave sustained attention to the periods in which researchers work within a common framework and to episodes when that framework changes. The subject was the organization of scientific work as much as any individual finding.

The caveat
This publication is a moment in the history of interpreting science, not proof that every field undergoes clean, sudden revolutions. The enduring usefulness of the concept should be separated from agreement with every part of Kuhn's account.
The book itself entered a debate about how science should be understood. Critics questioned its account of rational comparison across frameworks and the range of meanings attached to paradigm. Kuhn later clarified distinctions within the term. A word that helped identify shared assumptions also became an object of dispute.
The connection
Shared examples and standards let a research community work on common problems, even before individual puzzles are solved.
