Self-Attribution Bias
What Is Self-Attribution Bias?
Self-attribution bias is the tendency to attribute successes to one’s own skill or ability while blaming failures on external factors such as luck or market conditions.
Why It Matters
This bias can distort learning and decision-making. It may lead to:
- overconfidence after success

How Self-Attribution Bias Works
People affected by this bias:
- credit themselves for positive outcomes
- blame external factors for negative outcomes
- reinforce existing beliefs
- avoid accountability
- fail to adjust strategies
This creates a cycle that limits improvement.
Example
An investor attributes gains to their skill but blames losses on “bad market timing.”
