The Wason Family

The Wason Family is a famous example in psychology illustrating how people tend to seek confirming evidence rather than questioning their assumptions. In the classic task, individuals are asked to test a rule—such as "If a card shows a vowel on one side, then an even number on the other." People often choose cards that would confirm this rule but neglect cards that could disprove it, revealing common logical biases. This experiment highlights how human reasoning can be influenced byconfirmation bias, affecting decision-making and problem-solving in everyday life.
