The Clock

The thing you keep postponing. Now, or later?

650 people have stood exactly here. 70 of them are still inside it — their capsules have not opened yet. The rest already know how it went.

The answer changes depending on when you ask

This is the finding that matters, and it is the reason a snapshot of opinion is misleading. Shortly after the decision, the people who put it off are happier. Years later, the people who did it now are — and by a wider margin.

Regret about doing it now fades. Regret about putting it off accrues.

Common questions

What usually happens to people who did it now?

In this archive, 80% of people who did it now said they would do it again when asked around four years later. At six months it was 52%. Regret about doing it now tends to fade as time passes.

Is it better to doing it now or putting it off?

Neither, universally — and the honest answer changes with time. Early on, put it off looks better (64% against 52% at six months). Later it reverses (80% against 39% at four years). The two lines cross at about 13 months.

How is this measured?

Every capsule records a decision and a confidence level before the outcome is known, then the person is asked afterwards whether they would decide the same way again. The percentages are Gaussian-smoothed over 580 answered capsules. Where too few sit under the kernel, no figure is shown rather than a noisy one.

Is this advice?

No. It is a record of what happened to other people, which is a different and more useful thing. Nobody here knows your situation.

You are about to decide something

Write down the real reason and how sure you are, before you know how it goes. In 30, 90 or 365 days it opens and asks you one question — and you find out whether your judgement was worth anything.
