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 direction of a moving particle. At a given time, any one screen of a nine-screen matrix could be observed on a plasma display screen. Confirmatory strategies were the rule, even though half the subjects had been carefully instructed in strong inference. Falsification was counterproductive for some subjects…

When falsification fails
This study investigated the effectiveness of a falsification logic at early and late stages of the hypothesis testing process. The subject’s task was to discover the “laws of motion” in a

Abstract Experimental research on confirmation and disconfirmation as scientific reasoning strategies suggests that these terms are imprecise and should be replaced by positive and negative test
Confirmation, Disconfirmation, and Informa-tion in Hypothesis Testing
Strategies for hypothesis testing in scientific investigation and everyday reasoning have interested both psychologists and philosophers. A number of these scholars stress the importance of
A Comparison of Disconfirmatory, Confirmatory and Control Strategies on Wason's 2–4–6 Task
Attempts to instruct subjects to falsify on inference tasks designed to model scientific problem-solving have indicated that, in most cases, falsification does not lead to improved performance. The
Can Scientists Rationally Assess Conditional Inferences?
TLDR
In the present study, results obtained from twenty research scientists using Yachanin's modified task are reported, showing understanding of the power of disconfirmatory data in assessing conditionals, and of the possible error of affirming the consequent when only confirmatory data are sought.
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
Strategies of Rule Discovery in an Inference Task
TLDR
A series of experiments which employed a rule discovery task, the 2-4-6 problem first described by Wason, modified subjects confirmatory tendencies and introduced subjects to the possibility of disconfirmation only after they had developed a strongly held hypothesis through the use of confirmatory evidence.
Modeling and critiquing the confirmation bias in human reasoning
TLDR
Empirical evidence is presented suggesting that computers can interact with humans by qualitatively modeling and detecting their confirmation bias and by offering criticism strategies that will effectively mitigate the unwanted effects.

Abstract The object of this paper is to show why recent research in the psychology of deductive and probabilistic reasoning does not have "bleak implications for human rationality," as has sometimes
Error, Falsification and Scientific Inference: An Experimental Investigation
This paper reports the results of four experiments designed to test the methodological falsificationist's assumption that replication is sufficient to prevent the possibility of error from being used

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

TLDR
It is argued that the subjects did not give evidence of having acquired the characteristics of Piaget's “formal operational thought,” and it is suggested that the difficulty is due to a mental set for expecting a relation of truth, correspondence, or match to hold between sentences and states of affairs.
On the Failure to Eliminate Hypotheses in a Conceptual Task
TLDR
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.
Strong Inference: Certain systematic methods of scientific thinking may produce much more rapid progress than others.
TLDR
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.
