Confirmation Bias
Description
Confirmation Bias is simply the tendency for individuals to favor information or data that support their beliefs. It is the tendency for people to only seek out information that conforms to their pre-existing view points, and subsequently ignore information that goes against them. It is a type of cognitive bias and a form of selection bias toward confirmation of the hypothesis under study. Avoiding confirmation bias is an important part of rationalism and in science in general. This is achieved by setting up problems so that you must find ways of disproving your hypothesis (see falsifiability).

Example
Psychic “readings” is that listeners apply a confirmation bias which fits the psychic’s statements to their own lives. By making a large number of ambiguous statements in each sitting, the psychic gives the client more opportunities to find a match. This is one of the techniques of cold reading, with which a psychic can deliver a subjectively impressive reading without any prior information about the client.
