Self-belief does not necessarily ensure success, but self-disbelief assuredly spawns failure.
Albert BanduraThe difficulty in judging what type of behavior works well arises not only because a given course of action does not always produce the outcomes. Similar outcomes can occur for reasons other than the person's actions, which further complicates inferential judgment. Effects that arise independently of one's actions distort the influence of similar effects produced by the actions, but only on some occasions. Given a strong cognitive set to perceive regularities, even chance joint occurrences of events can be easily misjudged as genuine relationships of low contingent probability
Albert BanduraPerceived 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
Albert BanduraIt is no more informative to speak of self-efficacy in global terms than to speak of nonspecific social behavior
