INTRODUCTION

English translation pending.

CORE DEFINITION

A motivational attribution bias studied in social psychology and linked to attribution theory, self-enhancement, and the fundamental attribution error. People explain their own outcomes in self-flattering terms: successes are attributed to ability and effort, failures to luck, circumstance, or other people. Cross-cultural research finds the pattern stronger in individualist cultures and weaker in collectivist ones, tracking differences in self-construal. It protects self-esteem and sustains motivation, but it distorts causal understanding and impedes learning from failure.

SCAFFOLDING EFFECT

Reduce cognitive load

- Filter check: after an outcome, inspect your explanation for a self-flattering slant before accepting it. - Perspective swap: ask how you would explain the identical result if it had happened to someone else. - Review design: in team retrospectives, have each party list their own contribution before assigning cause elsewhere.

Anchor fast decisions

Self-esteem depends on a coherent story in which the self is competent, so explanations that preserve that story are preferred. The preference operates quickly and feels like perception rather than motivated reasoning, which is why introspection rarely catches it. The bias strengthens when the outcome matters personally and weakens under external accountability, because being answerable raises the cost of a distorted account. This makes review structures rather than willpower the practical remedy.
