Scientific behavior, interest, talent, and achievement can be and have been investigated from each of the fundamental subdisciplines in psychology. Simply put, there is a psychology behind science. I review and summarize the major empirical findings from different subdisciplines-namely, cognitive, developmental, personality, social, and clinical. For the last 10 years, the discipline of the psychology of science has shown some real promise in becoming a new psychological subdiscipline in its own right. I review some of the evidence for such a claim.
