developmental costs of high self-esteem

Two potential developmental costs of high self-esteem were investigated. One was that high self-esteem leads children to act on antisocial cognitions (the disposition activating hypothesis). The other was that high self-esteem leads children to rationalize antisocial conduct (the disposition-rationalizing hypothesis). Both hypotheses were explored in two longitudinal studies with preadolescents. In Study 1 (N = 189) the antisocial behavior was aggression; in Study 2 (N = 407) the antisocial behavior under focus was avoidance of the mother. There was little evidence for the disposition-activating hypothesis in either study but considerable support for the disposition-rationalizing hypothesis in both studies. Over time, aggressive children with high self-esteem increasingly valued the rewards that aggression offers and belittled their victims, and avoidant children with high self-esteem increasingly viewed their mother as harassing and uninvolved. Results therefore suggest that for antisocial children, high self-esteem carries costs, for both themselves and others.
