Self-Serving Bias

- Need To Act Fast
The charge
We credit our successes more to skill and effort, and our failures more to bad luck or circumstance.
How it operates
This protects self-esteem and status, and we have easy access to our own intentions and excuses when things go badly.
Logged incidents
- Incident 01
A PM credits product instincts for a growth spike but blames seasonality for a decline.
- Incident 02
A manager treats a good hire as judgment and a bad hire as a weak talent pool.
- Incident 03
A trader calls gains skill and losses market irrationality.
What to watch for
Notice when your explanations for wins and losses conveniently protect your self-image. Ask: 'Would I explain this outcome the same way if someone else got it?'
Recommended action
Keep a decision journal and run after-action reviews that compare predicted versus actual outcomes.
