Logic and the psychology of reasoning

This chapter takes as its starting point the widespread view that logic and reasoning are closely related. It briefly surveys the historical developments leading to this view, and then discusses empirical findings pertaining to the question of whether deductive logic is an adequate descriptive model for human reasoning. This body of research suggests that there are significant, systematic discrepancies between the canons of deductive logic and human reasoning, and thus that logic does not offer an adequate description of human reasoning.
