In the Wason Selection Task (1968), participants overwhelmingly select confirming cards rather than falsifying ones, demonstrating confirmation bias in rule-testing.
Summary
When people are asked to test whether a rule holds, they consistently reach for examples that would support the rule rather than the ones that could expose it as false. This well-documented finding anchors the system's understanding that humans default to seeking confirming evidence over disconfirming evidence, a tendency any model of human reasoning must account for.
