# Self-Attribution Bias

*Behavioral Finance — Finicade finance glossary*

Self-attribution bias credits successes to your skill and blames failures on bad luck. It's the engine that converts a lucky run into overconfidence, since a rising market makes everyone feel talented. It also blocks learning entirely: a process that only ever updates in one direction cannot improve, which is why the useful post-mortem is on winners as well as losers.
