We Were Only Hunting for Examples That Fit

🔢 «2, 4, 6 fits my rule» — work out the one hidden rule. Enter three numbers and you get back «yes» or «no», as often as you like. Most people only try things they expect a «yes» from: 8·10·12, 20·22·24. But the rule was simply «three numbers that increase». 📋 Second, review. Tests that came back «yes» cannot narrow the rule — going up by 2, three even numbers, and adding to 12 all pass 2·4·6 just the same. It is the «no» answers that split the candidates. If you never got a single no, you confirmed but never tried to break it. ✂️ Third, what is worth testing. 2·4·6 passes «all four» candidates, so whatever comes back you learn nothing. 8·10·12 passes three; 1·3·5 passes only two — the test that cuts them in half teaches the most.

About this app
This interactive critical-thinking exercise presents the classic hidden-rule puzzle starting with 2, 4, 6. Enter three numbers and receive yes-or-no feedback while testing candidate rules, then review whether your tests produced useful counterexamples. The app demonstrates confirmation bias by comparing rules such as increasing numbers, numbers increasing by 2, three even numbers, and numbers summing to 12.
