Watch for
An uneven story where success is always personal and failure is always external.
Outcome & SelfBias #12
Self-Serving Bias
We credit ourselves for wins and the world for losses.
The tendency to attribute positive outcomes to our own character or effort, and negative outcomes to external factors beyond our control.
Why it matters: A fundamental attribution pattern in social psychology. Protects self-esteem but distorts learning.
Try this
Ask what you personally controlled on both the good and bad outcomes.
Real-world example
Calling a success "my skill" but blaming failure on bad luck or poor tools.
Key researchers
Fritz Heider, Bernard Weiner
First described in 1958
Psychological mechanism
Self-Esteem Maintenance and Ego Defense. Distorting causality protects our internal self-worth and allows us to present a competent image to our social group, preventing the psychological pain of self-reproach.

Debrief
Self-serving bias is not vanity — it is a protective mechanism that preserves motivation and self-esteem. The cost is that it prevents learning from failures. The most effective leaders actively look for what they personally could have done differently, especially after negative outcomes.
