Hypotheses and theories are related, but they aren't the same thing.

Think of the hierarchy this way:

Hypothesis

A specific, testable proposition.

“Researchers receiving more institutional funding publish more articles on the funded topic.”

Theory

A broader explanatory framework consisting of concepts and relationships that can generate multiple hypotheses.

For example:

“Institutional incentives shape the production and distribution of knowledge.”

From that broader theory, you might derive several hypotheses:

Funding influences research topics.

Prestige influences citation.

Curricular selection influences what students encounter.

Publication practices influence which interpretations become visible.

So:

Theory that generates hypotheses and then hypotheses are tested against evidence.

A theory is therefore generally broader and more interconnected than a single hypothesis.
