You said thirty minutes.
It took forty-seven.
Everything takes longer than you think. Plannacy tells you by how much — and that number is learnable.
The study that named the planning fallacy. Only ~30% finished by the date they picked themselves — and knowing about the bias didn’t save them. Buehler, Griffin & Ross (1994)
THE MOMENT
Three seconds. Then it’s sealed.
Type it the way you’d say it — “home by 17:00” — and press and hold. Once locked you can’t edit it, which is the entire point.
THE PAYOFF
One number that doesn’t flatter you.
It starts from a prior, so one lucky guess can’t fake it. It can go down. And it says what it means — typically out by about 1.3× — instead of leaving you to wonder whether 77 is good.
THE EDGE
It knows things about you that you don’t.
That your work runs 1.7× long. That mornings beat evenings. So the moment you type “30 minutes”, it tells you what your last five Calls like this actually took — and then lets you decide anyway.
Two seconds of thought,
