In 1960 Wason developed the first of many tasks he would devise to reveal the failures of human reasoning. The "2-4-6" task was the first experiment that showed people to be illogical and irrational. In this study, subjects were told that the experimenter had a rule in mind that only applied to sets of threes.
The Wason selection task (or four-card problem) is a logic puzzle devised by Peter Cathcart Wason in 1966. [1] [2] [3] It is one of the most famous tasks in the study of deductive reasoning. [4] An example of the puzzle is: You are shown a set of four cards placed on a table, each of which has a number on one side and a color on the other.
The classic example of subjects' congruence bias was discovered by Peter Wason (1960, 1968). Here, the experimenter gave subjects the number sequence "2, 4, 6", telling the subjects that this sequence followed a particular rule and instructing subjects to find the rule underlying the sequence logic.
In Peter Wason's initial experiment published in 1960 (which does not mention the term "confirmation bias"), he repeatedly challenged participants to identify a rule applying to triples of numbers. They were told that (2,4,6) fits the rule. They generated triples, and the experimenter told them whether each triple conformed to the rule. [3]: 179
The Wason selection task provides evidence for the matching bias. [15] The test is designed as a measure of a person's logical thinking ability. [50] Performance on the Wason Selection Task is sensitive to the content and context with which it is presented. If you introduce a negative component into the conditional statement of the Wason ...

Jonathan St B. T. Evans (born 30 June 1948) [2] is a British cognitive psychologist, currently Emeritus Professor of Psychology at the University of Plymouth. [3] In 1975, with Peter Wason, Evans proposed one of the first dual-process theories of reasoning, an idea later developed and popularized by Daniel Kahneman.
