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]
Further, confirmation biases can sustain scientific theories or research programs in the face of inadequate or even contradictory evidence. [60] [95] The discipline of parapsychology is often cited as an example. [96] An experimenter's confirmation bias can potentially affect which data are reported.
Confirmation bias takes effect in the later stages of selective attention, when the individual has already started noticing the specific stimulus. By focusing on this specific stimulus, the individual notices it more, therefore confirming their suspicions of it occurring more frequently, even though in reality the frequency has not changed.
In some academic disciplines, the study of bias is very popular. For instance, bias is a wide spread and well studied phenomenon because most decisions that concern the minds and hearts of entrepreneurs are computationally intractable. [11] Cognitive biases can create other issues that arise in everyday life.
Selective exposure has also been known and defined as "congeniality bias" or "confirmation bias" in various texts throughout the years. [1] According to the historical use of the term, people tend to select specific aspects of exposed information which they incorporate into their mindset.
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”.
Another key example of observer bias is a 1963 study, "Psychology of the Scientist: V. Three Experiments in Experimenter Bias", [9] published by researchers Robert Rosenthal and Kermit L. Fode at the University of North Dakota. In this study, Rosenthal and Fode gave a group of twelve psychology students a total of sixty rats to run in some ...
One consequence of naïve realism is referred to as the bias blind spot, which is the ability to recognize cognitive and motivational biases in others while failing to recognize the impact of bias on the self. In a study conducted by Pronin, Lin, and Ross (2002), Stanford students completed a questionnaire about various biases in social ...
