Duration perception · no clock

A Minute, Exactly

Press start. Press stop when you think sixty seconds have gone. The face shows you nothing while it runs — no digits, no ticking hand, and no counting out loud. Then find out how far off you were, and where that puts you.

Space or Enter works too.

About This Test

You have a clock inside you, and it is bad. Not catastrophically bad — most people can feel out a minute to within about ten seconds — but bad in a way you never notice, because nothing in ordinary life ever asks you to check it against the real thing.

This is that check. The watch runs blind: while it is counting there is no hand, no digit, no rhythm on screen you could latch onto. All you have is the sensation of a minute passing, which turns out to be a surprisingly slippery thing to hold. When you stop it, your error is measured and placed on a curve of how humans generally do at this.

How To Play

  1. Press the face to start. The dial goes dark and gives you nothing back.
  2. Wait until a minute feels finished, then press it again. Space and Enter work too.
  3. Don't count. Counting turns this into a test of your counting rhythm, which is a different and much duller thing.
  4. The hand sweeps to where you actually landed, and your miss is plotted against the distribution. Then try it again while bored, or anxious, and watch the number move.

Why This Exists

Because duration perception is the one sense nobody thinks of as a sense. You know your eyesight is imperfect and you have probably had it measured. Nobody has ever measured how well you perceive the passage of a minute, and yet you rely on that estimate constantly — judging how long you have been in a meeting, how long a hold queue has lasted, how long ago you put something in the oven.

It is also the most easily distorted faculty you own. Anxiety runs your internal clock fast, so an anxious minute feels long and you stop early. Absorption runs it slow, so an interesting minute vanishes and you overshoot. The same person, tested twice in one day, can land twenty seconds apart. That instability is the actual finding here — not the number, but how much the number moves.

Frequently Asked Questions

What is A Minute, Exactly?

It is a free time perception test. You press start on a stopwatch that shows you nothing while it runs, then press stop the moment you believe sixty seconds have passed. Your error is then plotted on a reference curve of human duration estimates so you can see where your internal clock sits.

How accurate is the average person at estimating a minute?

Most people stop early. Typical estimates of a sixty second interval land somewhere between fifty and sixty seconds, with a spread of roughly twelve seconds either side, so a miss of under six seconds already puts you ahead of most people and a miss of under two seconds is genuinely rare.

Why can't I count the seconds?

You can, but then you are testing your counting rhythm rather than your sense of duration. Counting replaces the thing being measured with a metronome you supply yourself. The test is far more interesting, and far less flattering, if you simply wait until a minute feels finished.

Is this the same as a reaction time test?

No. Reaction time measures how quickly your nervous system responds to something that has already happened, in milliseconds. This measures duration perception, which is a separate faculty running on a much slower internal clock, and the two are almost entirely unrelated. Fast reflexes do not make you a good judge of a minute.

Why does time feel different when I am bored or anxious?

Your internal clock is not a fixed oscillator. Arousal speeds it up and attention to time stretches it, so an anxious or bored minute is subjectively longer and you tend to stop the watch early. Absorbed in something, the opposite happens and you overshoot. Running the test twice in two different moods is the most revealing way to play it.

Is my result stored or compared to other players live?

No. Nothing is uploaded and nothing is saved once you close the tab. The curve you are measured against is a fixed statistical model of how humans estimate a minute, computed in your browser, so the comparison is to that reference rather than to live players.
