Term: Confirmation bias
Definition (Myers): A tendency to search for information that confirms one's preconceptions.1
Definition (alternative): Tendency for people to confirm their preconceptions or hypotheses, independently of whether or not they are true.2
Contextual explanation: Someone has confirmation bias if they look for things that justify their own beliefs. For example, let's say you believe your sister stole your cell phone. You will then keep looking for 'proof' that confirms that she was the culprit; i.e. if she doesn't use her cell phone around you, if you find your cell phone key chain in her room.
