Hi Product Hunt 👋 I kept running into the same questions at work and just about everywhere else. Why the same proposal lands differently at 10am and at the end of a long day of decisions. Why asking a small favor first makes the real ask easier. Why a whole meeting nods along with an idea nobody actually likes. Why your own nerves are far less visible to everyone else than they feel to you. Those all have names, experiments behind them, and explanations you can learn in about a minute. It is not only about reading people. Why the first second on a clock feels too long. Why a dish tastes better on a heavier plate. Why you can stare at a scene and miss the one thing that changed. Memory, perception, judgment, how we act around each other — the questions range across all of it. Some questions cover findings that later attempts couldn't reproduce — the marshmallow test, power posing, ego depletion, the Stanford prison experiment. The original versions still circulate, so those explanations note what the follow-up studies found. How it works: - Rounds of five questions, three choices each. One round takes a couple of minutes. - Three levels — Beginner, Advanced, Expert — from the classics everyone half-remembers to the details of the experiments themselves. - The explanation is the product. The score is just what gets you to read it. - Fully offline. No login, no account, no sync. - 16 languages. Android only for now; iOS is in progress. If you try it, I'd love to know which question surprised you most — that's the best signal I have for what to write next. Thanks for taking a look!
