BiasForge
Run the famous experiments about how your brain fools itself — on YOURSELF. Guess the anchored number, fall for the bat-and-ball, meet the Linda problem. Each reveals the trap by name (anchoring, framing, base-rates, the peak-end rule…), tells you how sure scientists actually are, and shows the slow move that catches it. Once you can name a trick, you can beat it. No timer, no score to chase; on-device, no account. Ages 9–14.

Meet the cast
BiasForge's cast is your two ways of thinking, made into characters (not brain parts): Whim is the fast first impulse that jumps to the answer that FEELS right; Muse is the slow, careful second look that catches the trap. Mentor Solon keeps the studio calm — a bias isn't a failing, it's how everyone's fast brain works; naming it is how you catch it. And every finding carries a science-meter: is this solid, still argued, or a famous claim that didn't hold up? (Illustrated portraits + chapters, and a fuller cast of debiasing moves, are a tracked follow-on — R-WEB-CLONE-SPAWN-TRACKED.)
Whim
The fast first impulse (System 1) — jumps to the answer that feels right, and walks straight into the trap so you can see it
Muse
The slow, careful second look (System 2) — pauses, does the one check the trap counts on you to skip, and catches the bias
Solon
(Mentor) — a bias isn't a failing, it's how everyone's fast brain works; name it and you can beat it. Always ask how sure the scientists really are.
What's inside
Learning goal
Run the famous experiments about how your brain fools itself — on YOURSELF. Guess the anchored number, fall for the bat-and-ball, meet the Linda problem.
