Risk & uncertainty · Lesson 4 of 6

Reversible and irreversible choices

Choices you can undo deserve speed. Choices you cannot undo deserve time. Most people spend their care the other way round.

Some decisions are like a door you can walk back through: trying a new routine, taking a short course, rearranging your week, applying for a job. If it does not work, you return and try something else, having learned something.

Other decisions are like a door that locks once you are through: signing a long contract, selling something you cannot buy back, saying words that cannot be unsaid, making a promise others will build their lives on. These deserve slowness, second opinions and sleep.

Before any choice, ask: if this turns out wrong, how hard is it to undo? When the answer is easy, decide quickly and learn by doing. When the answer is hard or impossible, slow down on purpose, even if everyone around you is in a hurry.

See it happen

Kofi spends three weeks agonising over which note-taking app to use, then signs a two-year phone contract in ten minutes because the salesperson offered a free gift.

The first reaction

The app choice felt important because he uses it every day, and the contract felt simple because the offer seemed good.

With the idea

Asking how hard each would be to undo flips his effort: the app can be changed in an afternoon, so he picks one and moves on. The contract locks him in for two years, so he takes it home, compares, and reads the exit terms.

What changed

He matched his care to how reversible each choice was, not to how it felt.

Easy to take the wrong way

Reversible does not mean free. Undoing a choice still costs time and energy. It simply means that learning by trying is usually cheaper than trying to be certain first.
