Ask someone why they like what they like. The answer they give is real. It is also, almost certainly, not the reason.

There is a particular experience that everyone recognises and almost no one can explain: the immediate, visceral sense that something is not for you. Not wrong, not bad, not objectionable — simply not for you. A certain kind of restaurant, a certain kind of holiday, a certain way of furnishing a room. The feeling arrives before the reasoning, and the reasoning, when it comes, is largely a retrospective account of a judgment that was already made. Bourdieu spent his career trying to understand where that feeling comes from — and what it reveals about the social world that produced it.

His answer is habitus: the system of durable dispositions acquired through socialisation — in family, in education, in the social groups that form us before we have the capacity to choose them — that shapes perception, judgment, and action without conscious deliberation. Habitus is not habit in the simple sense of repeated behaviour. It is something deeper and more structuring: a practical sense of the social world, a feel for the game, that generates responses to situations that were never explicitly taught and cannot be fully articulated. It is, in fact, the sediment of a social trajectory that has become so thoroughly incorporated that it no longer feels like anything external at all. It feels like self.

This is why asking people to explain their preferences, choices, and behaviours reaches something real but incomplete. The account they give is shaped by the same habitus that produced the behaviour in the first place. They are translating into language something that was never in language — something that operated at the level of the body, of immediate perception, of the taken-for-granted structure of the world as it simply is. The translation is genuine, but always partial, always already filtered through the categories that habitus provides for making sense.

The concept of illusio deepens this. To participate in any social field — the art world, the financial industry, the research profession, the consumer market — requires taking its stakes seriously: treating its rules as real, its rewards as worth pursuing, its distinctions as meaningful. This investment is the precondition of participation. The person who is fully inside a field cannot easily see its rules as arbitrary, because those rules are the structure within which meaningful action is possible. This is what Bourdieu means by the capacity to see differences, make distinctions, and recognise value that is specific to a particular field.

If behaviour is generated by dispositions that feel like nature, then the most important things driving action are precisely the things people are least equipped to report. The research that surfaces the articulable — preferences, opinions, stated motivations — is working at the surface of a much deeper structure. Reaching that structure requires methods that work at the level of practice rather than at the level of account: attending to what people do as much as to what they say, to the choices they make without noticing they are making them, to the things they find so obvious they have never thought to question them.

The second direction is toward the analyst. The researcher working in a field is also inside it — shaped by a habitus, invested in a set of stakes, operating according to rules that feel like common sense rather than convention. The categories used to frame a research question, the responses treated as significant, the findings considered worth reporting — all of these are shaped by dispositions that the analyst did not choose and cannot fully see. It is a structural condition to be acknowledged and worked with — one that makes the comparison of perspectives, the deliberate exposure to unfamiliar fields, and the cultivation of genuine lateral vision methodological necessities.

Bourdieu developed these concepts through fieldwork in rural Algeria, then applied them to the consumption practices of French social classes in Distinction (1979), then to the art world, to gender, to the state. The framework travels because it is describing something that does not change with the field: the way social structures are lived from the inside, felt as natural, and reproduced through the very practices that they make possible.
