Explanations include information-processing rules (i.e., mental shortcuts), called heuristics, that the brain uses to produce decisions or judgments. Biases have a variety of forms and appear as cognitive ("cold") bias, such as mental noise, [5] or motivational ("hot") bias, such as when beliefs are distorted by wishful thinking. Both effects ...
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.
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.

This statement shows that when confronted with information that contradicts their beliefs, individuals may experience cognitive dissonance and avoid seeking it to reduce discomfort. This avoidance is the ostrich effect. The opposite, seeking information consistent with your beliefs, is a cognitive bias termed confirmation bias. [11]
Selective perception may refer to any number of cognitive biases in psychology related to the way expectations affect perception.Human judgment and decision making is distorted by an array of cognitive, perceptual and motivational biases, and people tend not to recognise their own bias, though they tend to easily recognise (and even overestimate) the operation of bias in human judgment by ...
Authority bias reveals people are more likely to be influenced by the opinions of authority figures. In the days before the medical professions made the connection between germs and disease, senior doctors, including Semmelweis’ professor Johann Klein, were scornful of Semmelweis' idea of preventing bacterial infections through antimicrobial strategies that are now widely accepted.

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.
