Comparisons in research and reasoning: Toward an integrative theory of social induction

Strong scientific theories give coherence to a body of research findings, make precise predictions about key phenomena, and guide the search for new discoveries. In social psychology, some contemporary theories fall short of this ideal. Mini-theories are prevalent (cf. Van Lange, Higgins, & Kruglanski, 2011), many predictions are merely directional (like this one!) and theorizing post-hoc. Guided by experimental reasoning, many researchers emphasize-and reify-empirical differences. Taking the experimental method as an epistemological gold standard, they regard comparative thinking as a criterion of rational thinking. Using examples from social judgment and decision making, we show how comparative reasoning can constrain theoretical development and bias assessments of human rationality. To encourage movement toward stronger theory, we describe a model of inductive reasoning in social contexts.
