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.

The observer-expectancy effect [a] is a form of reactivity in which a researcher's cognitive bias causes them to subconsciously influence the participants of an experiment. Confirmation bias can lead to the experimenter interpreting results incorrectly because of the tendency to look for information that conforms to their hypothesis, and ...
Participants in experiments who watched training videos and played debiasing games showed medium to large reductions both immediately and up to three months later in the extent to which they exhibited susceptibility to six cognitive biases: anchoring, bias blind spot, confirmation bias, fundamental attribution error, projection bias, and ...
The scientist, in other words, has to get the right answer in order to know that the experiment is working, or know that the experiment is working to get the right answer. Experimenter's regress occurs at the "research frontier" where the outcome of research is uncertain, for the scientist is dealing with "novel phenomena".
Laboratory experiments in which cognitive bias mitigation is an explicit goal are rare. One 1980 study [ 44 ] explored the notion of reducing the optimism bias by showing subjects other subjects' outputs from a reasoning task, with the result that their subsequent decision-making was somewhat debiased.
When you’re aware of the influence he and his aides exerted over the guards, the Stanford Prison Experiment can start to look like an exercise in confirmation bias. The BBC study, whose ...
Observer bias is the tendency of observers to not see what is there, but instead to see what they expect or want to see. This is a common occurrence in the everyday lives of many and is a significant problem that is sometimes encountered in scientific research and studies. [3]
