History & Social Studies: Assumption surfacing

What you'll be able to do: Find the unstated premises holding up your historical argument, the ones that feel like common sense and that the record often contradicts.

The premises that feel like facts

A student argues that economic hardship caused a revolution. The evidence is good: prices rose, wages fell, the revolution happened.

Surfaced, the argument contains an unstated premise: hardship reliably produces revolt. The historical record contradicts this comprehensively, most hardship produces endurance, emigration, crime, or nothing. Once the premise is named, the essay has a real question: why this hardship, this time, and not the fifty other episodes that didn't?

That's the move from a plausible narrative to an argument, and it's invisible until the premise is stated. Which is the difficulty: you can't check a premise you don't know you're using, and the ones doing the most work feel like common sense rather than claims.

The unstated premises that recur in this subject

- Hardship causes revolt. - People act in their material interest. Sometimes; often not, and the exceptions are the interesting cases. - Stated reasons are real reasons. - Institutions do what they were designed to do. - Change is driven by elites. Or its mirror, change is driven from below, both are positions, not defaults. - The categories in the sources are the categories that mattered to people. Census categories, legal categories, occupational labels, all constructed. - Absence of evidence is evidence of absence. Sometimes; often it's evidence about record-keeping. - Modern concepts apply. Class, nation, race, childhood, privacy, each has a history, and using them unreflectively is anachronism wearing analysis.

That last family is the most damaging and the least visible, because the words are ordinary.

How to run it

1. Present the reasoning, not the conclusion. Premises hide in the steps.
2. Ask for what you're relying on but haven't said.
3. Sort: premises you'd defend, premises you'd drop, and premises you didn't realise you'd adopted. The third is where the work is.
4. Test the load-bearing ones: if this were false, does my conclusion survive?
5. State the important ones in the essay. A stated and defended premise is strength; an unstated one is where a marker will push.

Here's my argument: [paste]. Don't tell me if I'm right. List the premises I'm relying on but haven't stated. For each, say whether my conclusion survives if it's false, and whether the historical record actually supports it.

That final clause is specific to this subject. Many unstated historical premises are empirical claims that can be checked against other cases, and checking them is itself historical work.

The framing question

What is this essay question assuming that I've accepted by answering it in these terms?

Exam questions embed premises. "Why did appeasement fail?" assumes it failed and assumes it was a coherent policy. "How far was the war inevitable?" assumes inevitability is the right frame. Noticing this doesn't mean refusing to answer, it means answering with the assumption named, which is a higher-band move.

Across the subjects

History. As above. Counterfactual reasoning is the standard test: if the premise is that X caused Y, what would have happened without X?

Political science. Rationality assumptions, and the premise that stated policy goals are actual goals.

Sociology. The premise that a category is natural rather than constructed, and that correlation between social facts indicates a mechanism.

Anthropology. The premise that the analyst's categories map onto the participants'. This is the discipline's founding methodological worry.

Geography. Environmental determinism, usually unstated. Terrain constrains and rarely determines, and the difference is where human decisions live.

International relations. That states are unitary actors with coherent interests, a premise so embedded in the vocabulary that it's hard to see.

Pitfalls

1. Confusing assumptions with errors. Most are choices, and many are defensible.
2. Surfacing trivia. Ask for the load-bearing ones.
3. Stopping at the list. The survives-if-false test is the method.
4. Only doing it when stuck. Run it on arguments you think are strong.
5. Naming a premise and not defending it. Stating it is half; the essay needs the justification.
6. The tell: every premise surfaced is one you'd already have named. Give it your real reasoning rather than a tidied version.

Try this today

Take the last paragraph of argument you wrote. Paste it and ask only: what am I assuming here that I haven't said?

Then for the most important one, ask whether the historical record actually supports it. That question turns a premise into a research question.
