Though a certain stereotype about a social group might not be true for an individual, people tend to remember the stereotype-consistent information better than any disconfirming evidence (Fyock & Stangor, 1994). Experiments have shown that mental association between expectancy-confirming information and the group label strongly affects recall and recognition memory. Memory confirmation bias also serves a role in stereotype maintenance. Some others claim that striking information is remembered best (i.e. Some theories state that information confirming prior beliefs is stored in the memory while contradictory evidence is not (i.e. Psychological theories vary in defining memory bias. To confirm their current beliefs, people may remember/recall information selectively. All subjects were provided with the same two studies, and after reading the detailed descriptions of the studies, participants still held their initial beliefs and supported their reasoning by providing “confirming” evidence from the studies and rejecting any contradictory evidence, or considering it inferior to the “confirming” evidence (Lord, Ross, & Lepper, 1979). It included participants who were in support of and others who were againstĬapital punishment. When provided with the same evidence, people’s interpretations could still be biased.īiased interpretation is shown in an experiment conducted by Stanford University on the topic of capital punishment. Various experiments have shown that people tend to not change their beliefs on complex issues even after being provided with research because of the way they interpret the evidence.Īdditionally, people accept “confirming” evidence more easily and critically evaluate the “disconfirming” evidence (this is known as disconfirmation bias) (Taber & Lodge, 2006). This type of bias explains that people interpret evidence with respect to their existing beliefs by typically evaluating confirming evidence differently than evidence that challenges their preconceptions. Though such evidence of the confirmation bias has appeared in psychological literature throughout history, the term ‘confirmation bias’ was first used in a 1977 paper detailing an experimental study on the topic (Mynatt, Doherty, & Tweney, 1977). Its results showed that the subjects chose responses that supported their hypotheses while rejecting contradictory evidence, and even though their hypotheses were not correct, they became confident in them quickly (Gray, 2010, p. One of the early demonstrations of confirmation bias appeared in an experiment by Peter Watson (1960) in which the subjects were to find the experimenter’s rule for sequencing numbers. ![]() The effect is stronger for emotionally charged issues and for deeply entrenched beliefs.Ĭonfirmation Bias is the tendency to look for information that supports, rather than rejects, one’s preconceptions, typically by interpreting evidence to confirm existing beliefs while rejecting or ignoring any conflicting data (American Psychological Association).When they gather or recall information selectively, or when they interpret it in a biased way. Confirmation bias happens when a person gives more weight to evidence that confirms their beliefs and undervalues evidence that could disprove it.Confirmation bias is the tendency of people to favor information that confirms their existing beliefs or hypotheses.So to your question, yes, even the best of them commit biases. They remembered comments that were never made, they made implicit meanings into explicit comments.etc When matched with the recordings, 90% of the specify points where omitted and half where incorrect. 2 weeks later the participants where asked to write down facts of the discussion. Tthomas, that is not a good example of hindsight bias which was the basis of mcdreamer's inquiry.Ģ British psychologist secretly recorded a discussion after a meeting of the Cambridge Psychological Society. ![]() Its a natural phenomenon like the northern lights. They nod like bobble-heads at each other and say "yeah, that makes sense". The other group is told that a long distance relationship strengths the two's love for each other. ![]() The group would agree because it sounds logical. The first group was told that a long distance relationship would weaken their bond. A psychological test was done on to groups of people about long distance relationships.
