Self-Serving Bias
Taking credit for success, blaming others for failure
What is it?
Self-serving bias is the common tendency to attribute successes to internal factors (our skill, effort, intelligence) while attributing failures to external factors (bad luck, others' mistakes, unfair circumstances). This asymmetric pattern protects self-esteem and maintains a positive self-image. It has been found in many cultures, though it tends to be stronger in Western, individualistic samples. The bias has both cognitive and motivational components: we process information differently when it concerns us rather than others, and we are motivated to see ourselves favorably. In organizations, self-serving bias creates conflict and prevents learning. Managers credit themselves for team successes but blame team members or market conditions for failures. Teams fall into blame cycles where everyone attributes problems to others. The bias distorts performance reviews, with each party having a skewed view of contributions. It also inflates confidence in future success: past wins reinforce belief in our abilities while past losses barely dent our self-assessment. Overcoming self-serving bias requires systematic accountability, seeking feedback from others, noting the role of luck and circumstance in successes, and honestly examining one's own contribution to failures.
Example
When a project succeeds, believing it was your leadership. When it fails, blaming market conditions. Attributing a win to skill but a loss to bad luck.

If the outcome were different, would I attribute it the same way?
What role did luck or circumstances play in this?
Am I taking credit for team successes but blaming others for failures?
What would an impartial observer say about my contribution?
How would I evaluate this if someone else did exactly what I did?
Before the outcome is known, write down your own role and the outside factors at play.
Ask for honest feedback from others about your role.
For each success, name at least one outside factor that helped, such as timing, luck or a colleague.
When things go wrong, ask yourself "what was my part in this?"
Keep a failure log to track your role in negative outcomes.
