Commit and stop re-evaluating

Once you’ve chosen, close the door instead of reopening the comparison.

Why it works

Reversible decisions are, counterintuitively, often less satisfying because the open door invites endless re-evaluation, which corrodes contentment with the choice. Treating a decision as closed lets psychological adaptation and rationalization do their work, increasing satisfaction — the same reason people grow happier with choices they can’t undo.

How to do it

1. After deciding, declare the decision closed.
2. Refuse to re-open the comparison or keep browsing alternatives.
3. Let yourself adapt to and invest in the choice you made.

Evidence

Supported by research finding that people report greater satisfaction with irreversible choices than reversible ones, because finality engages adaptation while reversibility keeps the comparison alive. Gilbert and Ebert also found people mis-predict this — they prefer keeping the option to change even though the changeable choice is what leaves them less satisfied, which is precisely the trap this practice closes. (observational)

Findings are from controlled studies on specific choices; this does not mean genuinely bad decisions should never be revisited.

Common mistake

Keeping the option to switch open "to be safe", which keeps the comparison running and quietly lowers your satisfaction with the choice.
