 An alternative version of the theory of self-serving bias states that the bias does not arise because people wish to protect their private self-esteem, but to protect their self-image (a self-presentational bias).This version of the theory would predict that people attribute their successes to situational factors, for fear that others will disapprove of them looking overly vain if they should attribute successes to themselves.For example, it is suggested that coming to believe that "good things happen to good people and bad things happen to bad people" will reduce feelings of vulnerability .
