Document Summary

Logic puzzle: every card has a # on one side and a letter on the other. Rule: if a card has a d on one side then it has a 3 on the other side. Shows four cards: d, f, 3, 7 Only d and 7 because you need to test one letter and one number, including a letter that was included in the original rule. There is a right way to logically solve the problem. Our minds are characterized by biases and flaws that lead to incorrect reasoning and the wrong solution. Humans deviate from the normative model and follow the descriptive model. Wason card problem shows the confirmation bias. Normative model : ideal model for how one should think rationally. Descriptive model : description for how humans actually think. Confirmation bias: humans tend to seek evidence that supports an opinion and not evidence that falsifies.
