Statistics keeps being right when instinct says no. Put 23 people in a room and the odds that two share a birthday are about 50%. Math Says Yes collects facts like that and walks through the reasoning until each one makes sense.
The format is a scrollable feed of cards. Most cards ask a quick question before revealing the answer, so learners commit to a guess first. That guess is where the surprise comes from, and the retention too. Explanations are short, written in plain language, and every fact cites its source. Many include an interactive chart or slider so students can change the numbers and watch the result move.

Reading is free and needs no account. Students sign in only to sync progress across devices or keep a streak going.
In class it works as a lesson starter: put a fact on the board, let students vote on the answer, then walk through the demo together. The data-literacy facts (misleading charts, survivorship bias) also slot into media-literacy units.

Most learning platforms ask for a commitment: create an account, pick a track, work through lessons. Math Says Yes is built for a two-minute gap โ open it, meet one surprising fact about probability or risk, understand why it's true, close it. Nothing is behind a paywall or a signup wall, every fact is sourced rather than asserted, and the interactive demos let you test a claim yourself instead of taking our word for it. It isn't a curriculum like Brilliant or Khan Academy; it's the thing that makes people curious enough to go looking for one. The daily five-question challenge gives you a reason to come back without a syllabus.
Math Says Yes's answer:
Math Says Yes turns counterintuitive statistics into something you scroll. Nearly every card asks you to guess before it reveals the answer, so you commit to a hunch first and then find out why your instinct was off โ that moment of being wrong is what makes the fact stick. Explanations are short and in plain language, every claim cites its source, and many cards include an interactive chart or slider so you can change the numbers and watch the result move. Reading is free and needs no account; signing in only adds progress sync and streaks.
Math Says Yes's answer:
Three overlapping groups. Curious adults who enjoy numbers but don't want a course โ the popular-science reading crowd who like having an intuition overturned. Students in secondary school and early university taking statistics or probability who want the ideas to click before an exam. And teachers, who use a card as a lesson starter: put the fact on the board, let the class vote, then walk through the demo together. The data-literacy cards on misleading charts and survivorship bias also fit media-literacy lessons.
