Rationalism is a term of art in psychology referring to the school of thought that sees certain elements of cognition as innate. (For this reason, it is sometimes used synonymously with the terms innatism or nativism.) Rationalism in psychology is identified with the philosophical tradition of the same name.rom the strict philosophical standpoint, rationalism is the view that all or most truth is deductive and a priori, deriving logically from a set of axioms gained by intuition or inherent knowledge (and not from studying the world around us empirically).
