Summary

This study by P. C. Wason examines how intelligent young adults make inferences in a conceptual task, specifically whether they seek confirming evidence alone or both confirming and disconfirming evidence to draw conclusions. The experiment involves a simple relational rule, "three numbers in increasing order of magnitude," and subjects are tasked with discovering this rule by making successive sets of three numbers and receiving feedback on whether they conform to the rule. The results show that many subjects fail to eliminate hypotheses and instead rely on confirming evidence, leading to incorrect conclusions. Only 6 out of 29 subjects reached the correct conclusion without previously reaching incorrect ones, while 13 reached one incorrect conclusion and 9 reached two or more incorrect conclusions. The study highlights the importance of considering disconfirming evidence in scientific thinking and the tendency for people to rely on confirmatory biases.
