Whether sociology can be called a science is among the oldest debates in the discipline, and a perennial favourite of UPSC examiners. The answer depends entirely on what one means by "science".

What makes a body of knowledge scientific?

A science is usually said to be empirical (based on observation), theoretical (building general explanations), cumulative (building on prior findings), value-neutral, and governed by a scientific method — systematic observation, hypothesis, and verification. The question is whether the study of society can meet these criteria.

The positivist claim

Auguste Comte, who coined the term sociology, held that society could be studied with the same methods as the natural world — a position called positivism. Émile Durkheim put this into practice in Suicide and The Rules of Sociological Method, insisting that "social facts" be treated as "things", external to and constraining the individual, and studied objectively.

The interpretive critique

Against positivism, Max Weber argued that social reality differs from natural reality in one decisive respect: it is meaningful. People act on the basis of subjective meanings, so explanation requires Verstehen — interpretive understanding — not just external observation. The social world cannot be reduced to law-like regularities without losing what makes it social.

Difficulties of a science of society

Several problems complicate any straightforward "yes":

  • Objectivity and value-neutrality. The sociologist is part of the society studied; complete detachment is difficult. Weber urged value-neutrality as a discipline, not an easy given.
  • Prediction. Human beings are reflexive — they respond to being studied — so precise prediction is elusive.
  • Experiment. Controlled experiments are rarely possible with whole societies.
  • Measurement. Many social phenomena resist quantification.

An answer that scores

The examiner rarely wants a flat "yes" or "no". The strong answer distinguishes senses of "science", presents the positivist and interpretive positions with their key thinkers, and concludes that sociology is a science in the broad sense — systematic and rigorous — while acknowledging that its subject matter demands methods the natural sciences do not need. Marxist thought adds a further layer, treating sociology as a science capable of guiding social change.

See the Karl Marx entry for the view of sociology as a science of change, and the related previous-year question on this exact theme.
