For many activities, people cannot rely solely on themselves in evaluating their ability level because such judgments require inferences from probabilistic indicants of talent about which they may have limited knowledge. Self-appraisals are, therefore, partly based on the opinions of others who presumably possess evaluative competence

People judge their capabilities partly by comparing their performances with those of others

Moreover, joint occurrences tend to be better recalled than instances when the effect does not occur. The proneness to remember confirming instances, but to overlook disconfirming ones, further serves to convert, in thought, coincidences into causalities.

Perceived self-efficacy influences the types of causal attributions people make for their performances

The performances of others are often selected as standards for self-improvement of abilities

Perceived self-efficacy also shapes causal thinking. In seeking solutions to difficult problems, those who perceived themselves as highly efficacious are inclined to attribute their failures to insufficient effort, whereas those of comparable skills but lower perceived self-efficacy ascribe their failures to deficient ability

Self efficacious children tend to attribute their successes to ability, but ability attributions affect performance indirectly through perceived self-efficacy
