The reliability of implicit stereotyping

Recent research has moved beyond the mere documentation of implicit stereotypes to consider how these measures relate to attitudes and predict behaviors. Little is known, however; about the basic psychometric properties of these measures. The present research includes three studies that provide evidence for test-retest reliability of implicit stereotypes when supraliminal priming of associated traits precedes a group categorization decision (Experiments 1 and 2) and when subliminal presentation of a group member precedes a decision about trait applicability (Experiment 3). Across the studies, significant evidence of implicit racial and gender stereotyping was obtained. These effects showed moderate test-retest reliability of comparable levels from 1 hour to 3 weeks. Implications of these findings for the use of implicit measures are considered.
