a theory postulating that corrections to bias in judgments occur when people are motivated and able to adjust their assessments of targets according to their naive theories of how the context influences their judgments. This may result in either assimilation or contrast effects depending on their perceptions of the magnitude and direction of bias. See also inclusion/exclusion model; set/reset model. [proposed by U.S. social psychologists Duane T. Wegener (1966– ) and Richard E. Petty (1951– )]
