We investigated individuals’ ability to use negative evidence in hypothesis testing. We compared performance in two versions of Wason's (1960) rule discovery problem. In the original version, a triple of numbers- {2, 4, 6}- was presented as an example of a rule that the experimenter had in mind (i.e., “increasing numbers”). Participants had to discover the rule by proposing new triples. In the other version, the same triple was presented as a counterexample to the experimenter's rule (i.e., “decreasing numbers”). We predicted that, in both conditions, participants would form hypotheses based on the features of the triple, and test only instances of the hypothesized rule. However, in the counter-example condition, such focused testing would invariably produce negative evidence. As a consequence, participants would be forced to revise their hypotheses. The reported results corroborated our predictions: Participants …
