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.

Similarly, a police detective may identify a suspect early in an investigation, but then may only seek confirming rather than disconfirming evidence.
For example, in their 2009 meta-analysis of Selective Exposure Theory, Hart et al. reported that "A 2004 survey by The Pew Research Center for the People & the Press (2006) found that Republicans are about 1.5 times more likely to report watching Fox News regularly than are Democrats (34% for Republicans and 20% of Democrats).
The list of cognitive biases has long been a topic of critique.

This statement shows that when confronted with information that contradicts their beliefs, individuals may experience cognitive dissonance and avoid seeking it to reduce discomfort.

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 is the tendency to favour information that is consistent with prior beliefs or values. [6] When Semmelweis introduced the handwashing proposal, the existing beliefs on disease transmission that other doctors held at that time included miasma theory , which suggests diseases were spread through “bad air”.
