Functionalism and conflict theory both start from above — systems, structures, institutions, groups — and work down to what people do.

Symbolic interactionism starts from the other end, and it makes a genuinely radical claim: that there is no society above the people in it, that structures exist only insofar as they are produced and reproduced in encounters, and that a sociology which cannot describe a conversation cannot describe anything.

Lessons 2.3.2, 2.3.3 and 2.4.2 introduced Cooley, Mead and Goffman as vocabulary. This lesson takes the school as a school: its premises, its methods, its achievements, and the objection it has never fully answered.

The three premises

Blumer coined "symbolic interactionism" in 1937 and set out its foundations in Symbolic Interactionism: Perspective and Method (1969). Its three premises are worth having exactly.

The inheritance

The methodological programme

Blumer's methodological writing is as important as his theory, and it is combative.

The two schools within the school

A real division, and worth knowing because it recurs in every methods argument.

The Chicago School (Blumer, Becker, Hughes, Strauss, Goffman loosely) — interpretive, ethnographic, sceptical of quantification, committed to fieldwork, and holding that meaning must be recovered through immersion.

The Iowa School (Manford Kuhn) — accepted the theory and rejected the methodology. Kuhn argued that interactionist concepts could and should be operationalised and measured, and developed the Twenty Statements Test ("Who am I?" answered twenty times) as a quantitative instrument for studying the self.

The dispute is the discipline's methodological split in miniature: whether the phenomena require interpretive methods or whether interpretive phenomena can be measured. Neither side won, and the argument recurs in every generation.

The great criticisms

It cannot handle structure or power. The most serious charge, made from every direction. If everything is negotiated in the encounter, what accounts for the fact that some parties consistently prevail? Gouldner attacked Goffman for producing a sociology of the "cocktail party" that ignored the institutional and economic order. Marxist critics noted that a framework which cannot see class, capital or the state is not equipped for most of what matters.

The reply available: interactionists do study power — Becker on labelling and the moral entrepreneur, Goffman on total institutions and stigma, the negotiated order literature on hierarchy. But the reply is partial, and the framework is genuinely better at describing how domination is enacted in an encounter than at explaining why the parties arrived with such unequal resources.

It is astructural and ahistorical. A negotiated order is negotiated within limits nobody at the table set. The interactionist can describe the negotiation and struggles to explain the limits.

It cannot generalise. Rich, deep accounts of specific settings, with unclear scope. What does one hospital tell you about hospitals? Interactionists reply that the aim is analytic rather than statistical generalisation — the identification of processes that recur — but the question of how far a process travels remains open in each case.

And the astructural bias may be built into the method. If you study by immersion in settings, you will see what happens in settings. The distribution of resources across settings, the historical processes that produced them, and the institutional arrangements that connect them are all invisible from inside any one of them.

The offspring

The school's productivity is best measured by what came out of it.

Labelling theory (10.2) — Becker, Lemert, Kitsuse. Deviance is not a quality of an act but a consequence of the application of rules and sanctions by others. "The deviant is one to whom the label has successfully been applied." This transformed criminology.

Dramaturgy (2.4.2, and 5.3.2) — Goffman's whole programme.

Grounded theory — Glaser and Strauss's The Discovery of Grounded Theory (1967), the most influential qualitative methodology of the last sixty years, is a direct product of this tradition: theory generated from data through constant comparison, rather than tested against it.

Social constructionism (2.4.1) — Berger and Luckmann synthesised this tradition with Schutz and Durkheim; and Spector and Kitsuse's constructionist account of social problems asks not what a problem is but how a condition comes to be defined as one.

Ethnomethodology (2.4.3) — Garfinkel's radicalisation: not what meanings people hold, but the methods by which they produce the sense of an orderly world, moment to moment.

Conversation analysis — Sacks, Schegloff and Jefferson's development, which turned the study of interaction into a precise empirical science of turn-taking, repair and sequence organisation, and which is arguably the most methodologically rigorous thing to come out of qualitative sociology.

The sociology of emotions — Hochschild's emotional labour (4.1.4) and the feeling rules literature.

And the sociology of work, medicine, education and deviance are all substantially interactionist in their qualitative traditions.

Why it matters

It supplies the discipline's account of how structure is actually made. Functionalism and conflict theory both tell you what structures do; neither tells you how a structure gets from one day to the next. The interactionist answer — that it is produced continuously by people interpreting each other, and therefore has to be brought off each time — is the best available, and it is what makes change explicable at the level where change actually happens.

It underwrites qualitative method. The argument that action follows from interpretation, and that interpretation must therefore be recovered, is the justification for ethnography, in-depth interviewing and observation. Every qualitative study rests on it, whether or not it cites Blumer.

It produces findings other methods cannot. Learning to be intoxicated; the institutional production of symptoms; the negotiated order of a hospital. Each contradicts the official account of its setting and each required someone to be there.

And it names the school's own limit honestly. A framework built by immersion in settings sees what happens in settings, and is weakest on the distribution of resources across them. That limit is real, and the next school in Part 5 — and Bourdieu in particular (5.10) — is substantially an attempt to fix it.
