Previous studies have suggested that when stereotypes are activated unconsciously, the person is unable to consciously control them. The possibility that unconscious activation of blood-type stereotypes leads to the selective processing of stereotype-consistent information resulting in the formation of stereotypical impressions, regardless of the degree of belief in blood-type personality theory was investigated. Female undergraduates (n=41) participated in an experiment in which they were subliminally presented with Blood-Type-A, B, or neutral stimuli, read an ambiguous scenario about a target person, and performed a memory task and an impression formation task. Results indicated that participants that were subliminally presented with Blood-type-B stimuli, retrieved information consistent with stereotypes about individuals with Blood-type-B, more often than participants in the other conditions. Conversely, subliminal presentations did not influence impression formation. The implication of automatic activation of blood-type stereotypes and the difficulties in conscious control are discussed.
