Detailed explanation-1: -The Wason selection test therefore evaluates subjects’ ability to find facts that violate a hypothesis, specifically a conditional hypothesis of the form If P then Q.
Detailed explanation-2: -The rule was “If the card shows an even number on one face, then its opposite face is red.” Only a card with both an even number on one face and something other than red on the other face can invalidate this rule: If the 3 card is red (or brown), that doesn’t violate the rule.
Detailed explanation-3: -The correct answer is that you must turn over only the 8 card and the blue card. Here is an explanation for each of the cards: 3 card: does not need to be turned over, because it is not even, so it cannot trigger the stated proposition.
Detailed explanation-4: -In Wason’s selection task, participants select whichever of four cards could provide evidence about the truth or falsity of a conditional rule. As our meta-analysis of hundreds of ex-periments corroborates, participants tend to overlook one of the cards that could falsify the rule.
