Bias

Confirmation Bias

The Wason 2-4-6 Task. Most people get this wrong — not because it's hard, but because their brain refuses to seek disconfirming evidence.

The Challenge

I'm thinking of a rule

I have a rule in mind that governs sequences of three numbers. This sequence follows the rule:

2 , 4 , 6

Your job: figure out the rule by testing other sequences. I'll tell you if each one follows the rule or not. When you're confident, guess the rule.

Test Sequences

Enter three numbers

Tests run: 0

Test at least 3 sequences before guessing
