Weber's position on values in social science is among the most demanding, most misunderstood and most contested things he wrote. It is also, unusually, a position about professional ethics as much as about method — a claim about what a scholar with a lectern owes the people sitting in front of them.

It is routinely reported as "sociology should be value-free," which is roughly half of what he said, and the half that makes no sense on its own.

The idea, in plain words

What science CAN do about values

This is the constructive half of Weber's position, and it is habitually ignored in favour of the prohibition. He identifies four things empirical inquiry can legitimately contribute to value questions, and they are substantial.

Weber's own summary of what a teacher owes a student is one of the finest statements of intellectual responsibility anyone has written:

"The primary task of a useful teacher is to teach his students to recognise 'inconvenient' facts — I mean facts that are inconvenient for their party opinions. And for every party opinion there are facts that are extremely inconvenient, for my own opinion no less than for others."

The criticisms, which are serious

Weber's position has been under sustained attack since the 1960s, and the attacks have force.

Gouldner: the "myth of a value-free sociology." Alvin Gouldner's 1962 paper is the classic assault. His argument: value-neutrality had become an ideology of professional convenience — a way for sociologists to take money from governments and foundations while disclaiming responsibility for what was done with their work; a licence for moral indifference dressed as rigour; and in practice, a stance that always favours the existing order, since refusing to criticise arrangements is not neutral towards them. He also noted, sharply, that Weber's own position was far more anguished than the comfortable version his American successors had adopted.

Becker: "Whose side are we on?" Howard Becker's 1967 presidential address argued that in any study of a hierarchical situation, neutrality is not available. Researchers inevitably adopt someone's perspective — the warden's or the prisoner's, the teacher's or the pupil's, the psychiatrist's or the patient's. The hierarchy of credibility means that the accounts of those at the top are treated as authoritative and those at the bottom as biased, so apparent neutrality in fact endorses the powerful. Becker's conclusion is not that objectivity is impossible but that one should state one's standpoint openly and do the work rigorously anyway.

Feminist standpoint theory (7.1). Harding, Hartsock, Smith and others argue that knowledge is always produced from a social location, that the standpoint of the dominant is presented as universal, and that the perspective of the subordinated can yield better knowledge — strong objectivity, in Harding's term — because those on the underside of a relation must understand both their own position and that of those above them, while the powerful need understand only their own.

Critical theory (5.5). Horkheimer's distinction between traditional and critical theory holds that a theory which does not orient itself towards emancipation ends up serving domination, and that the fact/value split is itself an ideological achievement of instrumental reason (4.3.3).

And the practical objection. Values enter research at points Weber's framework barely addresses: what gets funded, what counts as a variable, how categories are constructed, whose accounts are treated as data and whose as noise, which findings get published, which get cited. Value-freedom in the moment of inference does not touch any of this.

Is/ought, and why the prohibition holds

The underlying philosophical claim deserves stating, because it is the part of Weber's position that has survived best.

Hume's law: no set of purely descriptive statements entails a normative conclusion. From "this policy would reduce mortality by 3%" nothing follows about whether it should be adopted, until you add a premise about the value of life against whatever the policy costs. The extra premise is not a fact.

Weber accepts this fully, and draws the conclusion that the choice among ultimate values is not scientifically decidable — hence the polytheism of values (4.3.3). Each of the warring gods can be served consistently; none can be shown by evidence to be the right one.

And this is why he thought a scholar claiming scientific authority for a political conclusion was making a category error, not merely a professional lapse. They are asserting that their science entails something it cannot entail.

The counter-argument, which is live: some ethical claims may be more than preferences, and some empirical findings so overwhelming that the value premise required to resist them is not one anyone actually holds. If research shows a practice causes mass avoidable death, saying "science cannot tell you whether this is bad" is technically correct and practically absurd. Weber's framework handles this awkwardly, and most researchers in practice treat certain values — that avoidable suffering is bad, that evidence should be honestly reported — as not genuinely up for grabs.

Public sociology, and where the argument stands

The tension became institutional in Michael Burawoy's 2004 presidential address to the American Sociological Association, which proposed a fourfold division of the discipline's labour:

Professional sociology — research for other researchers, generating the knowledge base. Critical sociology — examining the discipline's own assumptions and values. Policy sociology — research for clients with defined problems. Public sociology — engagement with publics beyond the academy, in dialogue rather than instruction.

Burawoy's argument is that all four are necessary and that professional sociology's dominance had left the discipline unable to speak to the world. The subsequent debate — with critics arguing that public engagement compromises the credibility that makes engagement worth having — is Weber's question, restated a century later and still unresolved (12.2).

And the modern high-stakes version is the role of expertise in public controversy. Epidemiologists, climate scientists and economists advising on policy face Weber's dilemma directly: staying silent leaves the field to those with no evidence, and advocating openly risks the perception that findings track politics — which, once established, destroys the value of the expertise for everyone. There is no clean answer. Weber's is that the expert should state, as precisely as possible, what is known, what is uncertain, and what each available course would cost — and then say, explicitly, that the choice is the public's. It is a demanding discipline and it is not obviously wrong.

Why it matters

It states what a teacher owes a student, and the statement has not been improved on. Give them the evidence, especially where it is inconvenient for you. Show them the value conflicts and refuse to pretend they can be resolved technically. Do not use the fact that they cannot answer back.

It supplies the single most useful research discipline there is: apply the same standard to findings you like and findings you don't. Almost every failure of intellectual integrity, from motivated citation to quiet non-publication of null results, is a failure of exactly this rule.

It marks the boundary of what evidence can do. No quantity of facts settles a question about ultimate ends. Understanding this protects against two errors: pretending that a value dispute is a factual one, and dismissing evidence because a value is at stake.

And it poses a question this course cannot dodge. A great deal of sociology is motivated by moral concern about inequality, exclusion and suffering. Weber's demand is that the motivation must not be allowed to determine the findings — and that a discipline which lets it do so will eventually be believed by nobody, including on the occasions when it is right.
