Research has suggested that whereas stereotypical attitudes may be automatically activated, the response to these stereotypes can be controlled. Anything that interferes with self-control may result in more biased behavior. The ego strength model hypothesizes that after exerting self-control, subsequent self-control performance will suffer. Hence, depletion of ego strength may lead to increased prejudice. In 2 studies, depletion was found only to affect individuals who normally try to control their prejudicial responses. Participants who do not normally try to control their use of stereotypes were equally prejudiced, regardless of their level of ego strength. The results have implications for prejudice and stereotyping, as well as models of self-control.
