The term confirmation bias was coined by English psychologist Peter Wason. During the 1960s, Peter Cathcart Wason, a cognitive psychologist, conducted experiments later known as the Wason’s Rule Discovery Test. Depending on your students’ prior knowledge, you may need to provide them with the following definitions before or during the lesson: We compared performance in two versions of Wason's (1960) rule discovery problem. Cognitive psychologist Peter Wason discovered confirmation bias in a class experiment based on the 2-4-6 hypothesis rule (1960). Different senses of confirmation have been poorly distinguished in the literature, contributing to misinterpretations of both empirical findings . For each triple, they received feedback on whether it fit the … The activities on this web site have been completed 2551071 times.

The Wason Rule Discovery Test is where “subjects were asked to identify a rule that applies to series of triples of numbers. Inducing a Rule in Wason's 2–4–6 Task: A Test of the Information-Quantity and Goal-Complementarity Hypotheses. Frédéric Vallée-Tourangeau University of Hertfordshire, Hatfield , Hertfordshire, UK Correspondence F.Vallee-tourangeau@hertfordshire.ac.uk, N.G.Austin@hertfordshire.ac.uk, Neville G. Austin University of Hertfordshire, Hatfield , Hertfordshire, … In Study 1, participants who were low in dispositional trust were more likely to engage in negative hypothesis testing than participants high in dispositional trust. Wason (1960, 1968) developed a laboratory version of rule discovery to study people's hypothesis-testing strategies (in par- ticular, their use of confirmation and disconfirmation), in a task that "simulates a miniature scientific problem" (1960, p. 139). The present study investigated this theory by manipulating the to-bediscovered rules in order to produce both complementary and non-complementary DG versions of the task. The Wason rule discovery test is a psychological experiment where a rule needs to be discovered by asking yes-no questions, and Wason’s interpretation of the results nicely illustrates the difficulty of adopting the refutation mindset. He devised the Wason Rule Discovery Test to demonstrate that most people do not effectively test their hypotheses or beliefs. We first examine what "confirmation" means in hypothesis testing. This can be done by generating and testing hypotheses a number of times, … The first paper to use the term "confirmation bias" was Peter Wason's (1960) rule-discovery experiment. The Wason (1960) 2-4-6 rule discovery task provides an interesting window onto hypothesis-testing behaviour. In Study 2, trust and distrust were induced through an … For example, 1-2-3 is a different sequence from 3-2-1. you definitely need to turn over, and only that or those cards, in Successful participants also generated higher frequencies of confirmatory and … onto the second question. Ball}, year={2003} } Maggie Gale, Linden J. This exists in two main forms: The standard version requires participants to induce a single rule, whilst the logically identical Dual Goal (DG) version, introduced by Tweney et al. Distrust and the positive test heuristic: Dispositional and situated social distrust improves performance on the Wason rule discovery task. Reporters and media professionals define the term “confirmation bias,” and discuss its effect on how people approach and evaluate news and other information. It is one of the most famous tasks in the study of deductive reasoning. Facilitated rule discovery in Wason's 2–4–6 task: The role negative triples. Find peer-reviewed, published research using the Inquisit Wason Rule Discovery Test Wason, P.C. One of these is Klayman and Ha’s in 1987, which disputed the view of humans as hypotheses con-firmers. Klayman and Ha supported their analysis by citing an experiment that used the labels "DAX" and "MED" in place of "fits the rule" and "doesn't fit the rule". This avoided implying that the aim was to find a low-probability rule. The phenomenon was first described as confirmation bias by Peter Wason in 1960. hypothesis testing, namely, Wason’s (1960) rule-discovery task. Facilitated Rule Discovery in Wason’s 2-4-6 Task: The Role of Negative Triples Maggie Gale (M.Gale@derby.ac.uk) Institute of Behavioural Sciences, University of Derby Western Road, Mickleover Derby DE3 9GX, UK Linden J. Facilitated Rule Discovery in Wason’s 2-4-6 Task: The Role of Negative Triples Well maybe, but the Wason Selection Task, as it is called, is one of the most oft repeated tests of logical reasoning in the world of experimental psychology. Participants had to discover the rule by proposing new triples. Instead of trying to falsify a hypothesis to test it, people tend to try to confirm it.
