- Explain the concept of 'definition of the situation' and its significance in sociology. (Answer in 150 words)
Introduction
The concept holds that conduct follows from how a situation is read, not from what it objectively contains.

Body

1. What the concept holds: W. I. Thomas argued that action is preceded by a stage of examination in which the actor defines the situation, and that the definition governs what follows: if people define situations as real, they are real in their consequences. The group supplies most definitions, long before the child can form his own.
2. How it works in practice: Merton's self-fulfilling prophecy is the mechanism — a solvent bank defined as failing suffers the run that makes it fail. Goffman's actors compete to control the definition through impression management.
3. Its significance for sociology: It grounds the interpretative tradition and Berger and Luckmann's account of the social construction of reality; it underpins labelling theory of deviance, explains rumour and communal panic, and limits structural explanation, since structures act only as they are read.

Conclusion
Its power and its weakness are the same: it explains how definitions work, not whose definition prevails.
