Self-defeating behavior

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.

Superstitious behavior is still a common occurrence in modern society, seemingly impervious to intellectual progress that humans have made throughout history. While the desire to maintain a sense of control over one's environment has been investigated as one of the key motivations behind superstitious behavior, it has yet to be examined within the context of the self-concept. Threats to one's sense of control can also be construed as general threats to one's global sense of self-worth. Consequently, while superstitious behavior may be triggered by control threats, it may also occur as a result of any general threat to self-integrity. Moreover, if superstitious behavior is motivated by the desire to maintain overall self-integrity, then depriving individuals of a chance to engage in superstitious behavior should elicit subsequent attempts to repair self-integrity via alternative means. Three studies were conducted in order to establish this link between self functioning and superstitious behavior. Studies 1a and 1b did not find any evidence that manipulating the self-concept prior to an event designed to evoke superstition would increase the desire to engage in superstitious behavior. Threatening (or boosting) one's self-esteem prior to a game of chance did not affect participant's desire to use a superstitious strategy (aura color). Study 2 provided evidence that superstitious behavior is motivated by a desire to maintain self-integrity by showing that individuals deprived of their aura color prior to a game of chance were more likely to engage in self-affirmation subsequently. It also showed that the impact of depriving individuals of a superstitious strategy is independent of belief in such strategy.
