Check reversibility before you fear the downside

Most decisions are reversible; reserve maximum caution for the few that aren’t.

Why it works

Fear treats every decision as final, inflating the perceived cost of acting. Classifying a choice as a reversible "two-way door" versus an irreversible "one-way door" right-sizes the caution: reversible decisions can be made fast and undone, freeing you to act where regret of inaction would otherwise win. This separates real irreversibility from imagined finality.

How to do it

1. Ask whether this decision can be undone or adjusted later.
2. For reversible choices, decide quickly and treat them as experiments.
3. Reserve slow, regret-framework deliberation for truly irreversible ones.

Evidence

A practitioner decision principle (Bezos’s "one-way vs two-way doors"). It is mechanistic reasoning about reversibility and option value, not a studied psychological intervention, but it usefully counters the tendency to treat all decisions as permanent. (mechanistic)

This is decision-making wisdom, not tested research; the judgment of what is truly irreversible can itself be wrong.

Common mistake

Agonizing over a reversible decision as if it were permanent, spending regret-framework energy where a quick experiment would do.
