Flip a coin, then check your gut
Randomness as a decision tool: the coin-flip trick for revealing preferences, when chance beats deliberation, and a famous study on flipped life choices.

The oldest decision hack in the book: when you're stuck between two options, flip a coin — not to obey it, but to notice how you feel while it's in the air. If you catch yourself hoping for heads, you already had an answer. The coin didn't decide; it interrogated you. Our coin flipper works fine for this, with the bonus that nobody can accuse your browser of favoritism.
When you should actually obey the coin
Some decisions deserve real randomness, not just the gut-check. Trivial ties (where to eat) burn more energy deliberating than either outcome is worth — randomize and move. Contested fairness (who gets the last ticket, who presents first) is often better settled by visible chance than by argument; people accept losing a fair draw far more gracefully than losing a debate. And economist Steven Levitt's well-known coin-flip study found that people facing genuine 50/50 life dilemmas — quit or stay, move or not — reported being happier months later when the coin pushed them toward the CHANGE. We overweight the status quo; chance corrects the thumb on the scale.
Where chance doesn’t belong
Randomness is a tiebreaker, not a substitute for thinking. If the options aren't genuinely close, do the analysis — the coin is for after the spreadsheet ties. And never outsource to chance a decision you'll need to defend later ('the coin chose the contractor' impresses no auditor). Use it to break deadlocks, expose preferences, and keep trivial choices trivial. That's a surprisingly large share of life, which is roughly why this site exists.
