Selective hypothesis testing

A diverse set of biases that have been found to characterize judgment may be similarly mediated by a process of selective hypothesis testing. Our paper begins with a definition of selective hypothesis testing and an explanation of how and when this process leads to error We then review a diverse and often disconnected set of findings in the person perception, judgment, cognition, attitudes, attribution, and rule discovery literatures that can be explained by this process. Finally, we examine the question of why the selective testing of hypotheses occurs. Although the psychological literature suggests that selective hypothesis testing contributes to a variety of errors, in many contexts it may be a useful and efficient strategy that leads to satisfactory judgment.
