INTRODUCTION
English translation pending.
CORE DEFINITION
A motivational attribution bias studied in social psychology and linked to attribution theory and the fundamental attribution error. People explain their own outcomes in ways that protect self-esteem: positive results are credited to ability and effort, negative results to external obstacles or bad luck. The pattern is stronger in individualist cultures and weaker in collectivist ones, tracking differences in self-construal. It has a defensive function, sustaining motivation and mood, at the cost of accuracy about what actually caused an outcome, which is why it impairs learning from failure.
SCAFFOLDING EFFECT
Reduce cognitive load
- Attribution audit: after an outcome, list the internal and external causes you are inclined to credit and check the balance. - Reversal test: ask how you would explain the same result if the opposite person had produced it. - Learning focus: separate what you controlled from what you did not, then act only on the first.
Anchor fast decisions
Self-esteem is sustained by a coherent story in which the self is competent. Attributing success inward and failure outward keeps that story intact, and because the attribution happens quickly and feels like perception rather than motivated reasoning, it is difficult to notice from the inside. The bias strengthens when the outcome matters personally and weakens under external accountability, because being answerable raises the cost of a distorted explanation.
