Yes or no?
Ask your question in your head, press the button, and let chance decide: a beat of suspense, then your answer.
Why flipping a virtual coin actually works
When two options feel equally good, your brain stalls out, classic decision paralysis. The coin-flip trick (or this button) isn't really about the answer; it's about your reaction to it. If you read "NO" and feel a little pang of disappointment, you actually wanted the yes all along. Use it that way, as a gut-check detector, for small everyday choices, not for signing contracts.
Yes, no, or maybe: how the two modes work
In classic mode the odds are a clean 50/50, like a fair coin. Turn on "MAYBE" and all three answers come up with equal probability (one in three), handy when postponing the decision is a perfectly acceptable outcome too. The stats at the bottom track this session's answers, so you can see whether luck is on your side today.
The coin is there to show you what you wanted
The trick decision-makers have always known is that the value of the coin is not in the result: it is in the half second while it is in the air. In that instant most people notice they are hoping for one of the two faces, and that hope is the answer they were looking for.
If the result instead leaves you completely indifferent, that is just as useful: it means the two options really are worth the same and the time spent deciding is time wasted. In that case you take the one that came up and move on.
When it is worth letting chance decide
The test is the ratio between the cost of the choice and the cost of deciding: where to eat tonight, which of two films, who starts the game. These are decisions where ten minutes of thought costs more than any difference between the options.
It does not apply to choices that are hard to undo: changing job, signing a contract, buying a house. There the relief or disappointment you feel at the result is still useful information, but the decision has to be made by looking at the facts, not the coin.
Chance has no memory
Five «yes» in a row do not make the sixth less likely: every toss knows nothing about the ones before it. It is the gambler's fallacy, the one that makes people bet on red «because black came up eight times», and it applies identically here.
Long runs are in fact normal and expected: over a hundred tosses it is more likely that there is at least one run of six identical results than that there is none. A result that looks «too tidy» is usually the sign of fake randomness, not real randomness.
