Breaking down the question
The question has two linked parts. The first is a proposition to be affirmed and explained — that interaction is the focal point of sociology. The second is the analytical task: distinguishing sociological understanding of that interaction from common-sense understanding.
The examiner wants you to establish first why interaction, rather than the isolated individual, is the true unit of sociological analysis, and then to draw a clear, criterion-based contrast with common sense. A weak answer lists differences at random; a strong one organises the distinction around definite criteria such as method, generality, reflexivity and value neutrality. At 10 marks, be economical but precise.
How to approach it
Open by establishing that sociology studies not individuals in isolation but the patterned interaction between them — the reciprocal orientation of actors to one another that produces social relationships, groups and institutions. This justifies the claim in the question.
Then move to the distinction. Frame common sense as the taken-for-granted, unreflective knowledge people use in everyday life, and sociology as systematic, cumulative and empirically tested knowledge. Draw the contrast along clear criteria — origin, method, generality, objectivity and reflexivity. You may cite the sociological imagination and the discipline's self-critical stance. Our sociology and common sense notes develop these criteria more fully. Conclude by noting that sociology often begins from common sense but subjects it to scrutiny, sometimes confirming and sometimes overturning it.
Model answer
Sociology takes as its focal point not the isolated individual but interaction — the mutual, meaningful orientation of actors towards one another. When two or more people take account of each other and adjust their conduct accordingly, they generate social relationships, and from repeated patterns of interaction emerge groups, roles, norms and institutions. The individual acquires a social self only through such interaction; hence society itself is, at root, a web of interactions. This is why sociologists from Simmel to the symbolic interactionists have treated interaction as the elementary unit of the social.
Common sense also comments on this world, but it does so differently. Common sense is the stock of practical, taken-for-granted knowledge that people inherit through socialisation and use to navigate daily life. It is unreflective, often contradictory, culturally variable and rarely tested. Sociological knowledge, by contrast, is systematic and methodical: it proceeds through defined concepts, explicit theories and evidence gathered by recognised research methods. It is cumulative, building on and correcting earlier findings, whereas common sense simply persists. It aims at generality, seeking patterns and causes rather than isolated particulars, and it strives for objectivity and value neutrality, holding its assumptions up for scrutiny instead of assuming them.
Crucially, sociology is reflexive: it questions the very common sense from which it often begins. C. Wright Mills captured this with the sociological imagination, the capacity to connect private troubles to public issues and to see the individual within history and structure. Where common sense might explain unemployment as personal failing, sociology locates it in economic structures. Sociology may confirm common sense, but it may equally overturn it — showing, for instance, that suicide, seemingly the most private act, follows social patterns.
The two are therefore not simply opposed. Sociology takes the everyday interaction that common sense inhabits and renders it an object of disciplined, sceptical, evidence-based inquiry.
Examiner's perspective
The examiner is testing whether a candidate can do two things at once: justify interaction as sociology's focal concern and then discriminate sociological from common-sense knowledge with precision. Scripts that address only the second half, ignoring the claim about interaction, answer half the question.
The strongest answers organise the distinction around clear criteria — systematic method, cumulative growth, generality, objectivity and reflexivity — rather than offering a loose list. Reference to the sociological imagination and an illustrative example, such as suicide or unemployment, signals genuine command. A closing observation that sociology often begins from common sense but subjects it to critical testing shows the conceptual maturity examiners reward at this level.
