Present Bias
Definition
Present Bias is the inclination to undervalue future rewards in favor of immediate, smaller gratification.
Real-world examples
Opting for a chocolate bar today instead of a healthier body in six months, or postponing retirement savings because of current spending desires.
- Signing up for a gym in January but skipping workouts all year — the distant benefit loses to today's comfort.
- 'Buy now, pay later' feels painless because the cost is pushed onto a future self that seems like a different person.
How to design for it (nudge strategy)
Implement 'Save More Tomorrow' mechanisms where commitments are made for the future, or provide small, immediate rewards for actions with long-term benefits.
