The Stereotype Content Model(Glick & Fiske, 2001) tends to equates status and ability of people. In this study, status and ability were separated, and stimulus persons were presented in vignettes for two types of persons: high status - low ability and low status - high ability. A thousand English Data were collected through survey company, and the results showed that an interaction effect of stimulus person and system justification was statistically significant( β=.390, p=.004). Participants with low score of system justification scale (that is liberal person ) rated the stimulus person who had high status and low ability lower than the stimulus person who had low status and high ability compared with participants with high score of the scale. Furthermore we constructed a class perception scale, that means whether people perceive the social class is fixed. An interaction effect of the class perception and the stimulus person condition was also significant(β=.268, p=.001). Participants with high score in that scale evaluated the business person with low status and high ability as smarter and more likable than business person with high status and low ability. Overall, the impression of a person of low ability but high status was positive in the participants with high authoritarian tendencies. Those with lower authoritarian tendencies tended to rate lower-status and higher-ability stimulus person more highly. Cultural differences in the relationship between status and ability are also discussed.
