Treat your decision as more final than it is

Mentally close off the "undo" option to stop rumination and increase satisfaction.

Why it works

Reversible decisions keep the comparison space open: the unchosen option remains psychologically live, inviting continued evaluation and regret. Research by Gilbert and colleagues shows people consistently overestimate how much they will regret irreversible choices and underestimate their own ability to adapt — meaning the psychological safety of "you can always change it" actively undermines satisfaction.

How to do it

1. Once a choice is made, mentally frame it as final — avoid browsing alternatives or re-reading reviews.
2. Write a short statement about why this option fit your criteria; this consolidates the decision.
3. Allow yourself a single scheduled "reconsideration window" (e.g., 30 days out) rather than continuous re-evaluation.

Evidence

Gilbert et al. showed in laboratory experiments that people were happier with prints they could not exchange than with ones they could, contradicting the intuition that reversibility is always preferable. Affective-forecasting work adds the reason this stays hidden: people fail to anticipate that a changeable outcome keeps the comparison alive, so they choose reversibility and then feel worse than they predicted.

Lab findings on reversibility; real-world decisions involve higher stakes and varied cognitive styles. The core effect has replicated, though effect sizes differ by domain.

Common mistake

Deliberately leaving a decision "open" as insurance against regret, which actually keeps regret active by maintaining the comparison.
