For example, confirmation bias produces systematic errors in scientific research based on inductive reasoning (the gradual accumulation of supportive evidence). Similarly, a police detective may identify a suspect early in an investigation, but then may only seek confirming rather than disconfirming evidence.
Confirmation bias is the tendency to search for, interpret, focus on and remember information in a way that confirms one's preconceptions. [31] There are multiple other cognitive biases which involve or are types of confirmation bias: Backfire effect, a tendency to react to disconfirming evidence by strengthening one's previous beliefs. [32]
Selective exposure is a theory within the practice of psychology, often used in media and communication research, that historically refers to individuals' tendency to favor information which reinforces their pre-existing views while avoiding contradictory information.
However, confirmation bias is mainly a sub-conscious (innate) cognitive bias. In contrast, motivated reasoning (motivational bias) is a sub-conscious or conscious process by which one's emotions control the evidence supported or dismissed. For confirmation bias, the evidence or arguments can be logical as well as emotional.
Wason also ascribes participants' errors on this selection task due to confirmation bias. Confirmation bias compels people to seek the cards which confirm the rule; meanwhile, they overlook the main purpose of the experiment, which is to purposefully choose the cards that potentially disconfirm the rule.
For example, women seek evaluations that confirm their belief that they possess qualities associated with being a woman. Self-verification theory suggests that people may begin to shape others' evaluations of them before they even begin interacting with them. They may, for example, display identity cues (see: impression management). The most ...
Congruence bias is the tendency of people to over-rely on testing their initial hypothesis (the most congruent one) while neglecting to test alternative hypotheses. That is, people rarely try experiments that could disprove their initial belief, but rather try to repeat their initial results. It is a special case of the confirmation bias.
Confirmation bias can also lead to escalation of commitment as individuals are then less likely to recognize the negative results of their decisions. [7] On the other hand, if the results are recognized, they can be blamed on unforeseeable events occurring during the course of the project. The effect of sunk costs is often seen escalating ...
