Personal Validation Effect

Given a set of preexisting beliefs about how something in the world operates, a person is likely to find a way that two unrelated pieces of information are connected, and that connection confirms the belief. For example, the term is commonly used when describing the belief in paranormal phenomena. If someone experiences a strange sound and a feeling of cold in the home of a recently deceased person, it can be construed as evidence of a ghost, and the belief in the paranormal is confirmed in his/her mind.
