Research indicates that people have a high estimate of their personal
ability and assess their vulnerability to personal risk as less than t
heir peers. Even though these judgments have been found to be resistan
t to change, previous research suggests that making individuals accoun
table for their judgments may prevent certain illusory self-assessment
s developing. Two studies investigated whether accountability modifies
estimates of personal ability and vulnerability. Results indicated th
at making participants more accountable for their judgments significan
tly reduces positive self-assessments. There was also some suggestion
that the extent of the accountability effect is proportional to the ma
gnitude of the accountability manipulation.
