This or That Decider

Type two options into the boxes (Pizza vs Tacos by default) and click Decide. The tool runs a 3-second animation, then declares one of the two the winner. After the result, it asks 'How do you feel?' with two buttons: 'Great!' (you accept the result) or 'Actually, [the other one]' (you flip to the other option). That second button is the entire point of the tool: the moment you see the random pick and feel disappointed, you've just learned which one you actually wanted.

It's not a serious decision aid. The randomisation is a 50/50 coin flip; the tool isn't weighting cost, time, calories or any other factor. What it does well is force a decision out of someone who's been stuck for ten minutes between two restaurants. Use it for tiny choices that don't matter much (lunch, film, route home) and for medium choices where you've over-thought it and need a tiebreaker. Don't use it for genuinely consequential decisions; you need a pros-and-cons list, not a coin flip.

The 'How do you feel?' prompt after the result is borrowed from a classic decision-making technique: when you can't pick, flip a coin, and the moment the result lands, notice which one you wanted to win. If you're glad the coin showed Option A, then A is your real preference; if you're disappointed, B is. The tool just automates that trick. Most people who use it don't even need the random pick; they need the tiny moment of relief or disappointment that tells them what they actually want.

If you keep flipping the result with the 'Actually...' button until you're satisfied, you've used the tool perfectly. That's not a failure of the randomiser; that's you arriving at your real preference through elimination. The animation between options exists to give you that moment of suspense in which you commit emotionally to one outcome. A pure instant-result coin flip wouldn't trigger the same feeling.

Lunch decisions are by far the top use, followed by film/show decisions and 'should I go out tonight or stay in'. Couples and friend groups use it as a tiebreaker when they've been arguing in circles for fifteen minutes. Solo users use it to break analysis paralysis on tiny purchases (red mug or blue mug, this jumper or that one). It also works for binary ethical-but-not-serious dilemmas: 'tell my friend their haircut looks weird, or stay quiet'.

Don't use it for things that would benefit from research. 'Buy this house or that house' is not a coin-flip decision. 'Which job offer should I take' is not a coin-flip decision. For those, sit down with a list of pros and cons or talk to someone you trust. The this-or-that decider is a low-stakes tool for low-stakes decisions; using it for life choices is the equivalent of choosing your university by drawing names from a hat. Save it for the trivial stuff and you'll get good use out of it.

Decision fatigue is real. Once you've made 50 decisions in a day (what to wear, what to eat for breakfast, which email to answer first), tiny binary choices late in the day become disproportionately hard. Your brain is conserving glucose and would rather defer than commit. That's why people who eat the same breakfast every day or wear the same outfit (Steve Jobs, Mark Zuckerberg) report feeling sharper for the bigger decisions; they've eliminated the small ones.

If you find yourself reaching for this tool multiple times a day, you might be over-optioning your life. Try eating the same lunch on weekdays for a fortnight and see how much mental energy that frees up. Use the tool for the genuinely random choices (which film tonight) and try to reduce the number of trivial decisions you face overall. The [bucket list generator](/bucket-list-generator) is a counterpoint: it's for when you have too few choices, not too many.
