Perceived system longevity increases system justification and the legitimacy of inequality.

In two studies, we test the prediction that perceived longevity increases system justification and the legitimacy of inequality. In Study 1, the foundations of the capitalist system were portrayed as younger or older on a timeline. Participants scored higher on economic system justification and perceived capitalism as more legitimate when they were led to believe that this economic system was older. In Study 2, we manipulated the longevity of the Indian caste system and recruited both Indians and Americans. Both groups judged the caste system as more justifiable and legitimate when it was described as more longstanding. In addition, Indians reported more system dependence and judged the caste system as more justifiable and legitimate than Americans. Feelings of system dependence explained the effects of nationality, but not the effects of longevity, on the justification and legitimacy of the caste system. Perceived longevity is a novel contributor to system justification. Copyright © 2013 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]
