Abstract
Gilbert and Wilson review how humans simulate future events to predict hedonic consequences — and why those predictions systematically miss (impact bias, durability errors).

Read Projected regret — prospection explains why pre-lived failure feelings often overshoot lived experience.
Key findings
- Prospection mechanism — The brain pre-experiences futures; affective forecasts drive choice before outcomes occur.
- Impact bias — Predicted emotional intensity usually exceeds experienced intensity — dread is often louder in simulation.
- Durability error — Predicted duration of bad feelings exceeds actual recovery time — recovery is under-forecast.
- Future self bias — Present self overweight immediate simulation errors when negotiating with future self.
Limits
Review of forecasting literature — not a licence to ignore real risk. Use to calibrate pre-refusal, not to dismiss legitimate downside.
When to open this
Open when Projected regret or ambition work assigns failure feelings before any trial.
Try this week: recall one past setback you avoided in imagination — compare predicted vs actual emotional duration honestly.
