A theorist is a person who develops or advocates theories, especially in the fields of science, philosophy, and politics. The term can refer to anyone who creates a theoretical framework to explain a particular phenomenon or set of phenomena. A theorist may draw upon empirical evidence, logical reasoning, and existing theory to construct their own explanations for why things are the way they are. In academic settings, theorists often publish their ideas in scholarly journals or books so that others can review, critique, and build upon them.
