It has long been known that subjects in certain inference tasks will seek evidence which can confirm their present hypotheses, even in situations where disconfirmatory evidence could be more informative. We sought to alter this tendency in a series of experiments which employed a rule discovery task, the 2-4-6 problem first described by Wason. The first experiment instructionally modified subjects confirmatory tendencies. While a disconfirmatory strategy was easily induced, it did not lead to…

Hypothesis testing in a rule discovery problem: When a focused procedure is effective
Individuals’ ability to use negative evidence in hypothesis testing is investigated and predicted that, in both conditions, participants would form hypotheses based on the features of the triple, and test only instances of the hypothesized rule, but in the counter-example condition, such focused testing would invariably produce negative evidence.
Representational effects in a rule discovery task
In the Wason (1960) rule discovery task reasoners must infer a rule that governs the production of number sequences. The task instructions are designed such that reasoners’ initial hypotheses are
Evaluating Negative Tests and Refutations in a Rule Discovery Task
Subjects participating in Wason's rule discovery task (1960) overwhelmingly try to confirm rather than refute their currently held hypothesis. Such a strategy is often inadequate and runs counter to
Multiple Goal Facilitation in a Rule Discovery Task
The present study sought to expand previous research on Wason’s 2-4-6 task by exploring the limits of the multiple goal facilitation effect. In the original task subjects were given an initial triple

Collaborative discovery in a simple reasoning task Action editor :
In psychological experimental studies on scientific discovery, discussions have been made on the effects of collaborative discovery using simple experimental tasks, such as Wason s 2-4-6 task.
Hypothesis-Testing Strategies: Why two Goals are Better than One
An intriguing finding in the hypothesis-testing literature concerns a large increase in the proportion of subjects who discover a rule when they are asked to determine two rules rather than that rule
Sensible reasoning in two tasks: Rule discovery and hypothesis evaluation
The hypothesis testing skills of undergraduates were measured in two tasks: the 2-4-6 rule discovery task in which students generate and assess hypotheses, and a hypothesis evaluation task, which
From falsification to generating an alternative hypothesis: Exploring the role of the new-perspective hypothesis in successful 2-4-6 task performance
Previous research has found no consistent relationship between measures of disconfirmatory evidence, alternative hypotheses, and people's success in rule-discovery tasks. The present paper explores

A number of investigators have claimed that subjects show confirmation bias on a variety of reasoning tasks. However, subjects who were classified as “confirming” had often selected evidence that


A comparison of some inductive inference models
The psychology of discovery is explored in a laboratory setting using the inductive inference task of determining the mathematical function which fits a sample of coordinate values and it is concluded that random error, a graphical representation, sophisticated technology, experience with similar problems, and a geometrical cognitive style should produce a heuristic discovery process.
The psychology of inference and expectation: some preliminary remarks
The problems of inference are manifold: the first task facing the theorist concerned with them is to attempt an ordering of priorities, to decide which of them to tackle. One must assay not only the
On the Failure to Eliminate Hypotheses in a Conceptual Task
The results showed that those subjects, who reached two or more incorrect conclusions, were unable, or unwilling to test their hypotheses, and the implications are discussed in relation to scientific thinking.
Confirmation Bias in a Simulated Research Environment: An Experimental Study of Scientific Inference
Numerous authors (e.g., Popper, 1959) argue that scientists should try to falsify rather than confirm theories. However, recent empirical work (Wason and Johnson-Laird, 1972) suggests the existence
Consequences of Confirmation and Disconfirmation in a Simulated Research Environment
Advanced undergraduate science majors attempted for approximately 10h each to discover the laws governing a dynamic system. The system included 27 fixed objects, some of which influenced the
Eliminative and Enumerative Behaviour in a Conceptual Task
P. C. Wason's paper “On the Failure to Eliminate Hypotheses in a Conceptual Task” is criticized on the grounds that the task set is in important respects untypical of problem solving situations in
Strong Inference: Certain systematic methods of scientific thinking may produce much more rapid progress than others.
Anyone who looks at the matter closely will agree that some fields of science are moving forward very much faster than others, perhaps by an order of magnitude, if numbers could be put on such estimates.
The Processing of Positive and Negative Information
An affirmative statement which is known to be false and the complementary negative statement which is known to be true, provide the same information, i.e. that something is not the case. Similarly,
