Apophenia (/æpoʊˈfiːniə/) is the tendency to perceive meaningful connections between unrelated things.[1] The term (German: Apophänie from the Greek verb ἀποφαίνειν (apophaínein)) was coined by psychiatrist Klaus Conrad in his 1958 publication on the beginning stages of schizophrenia.[2] He defined it as "unmotivated seeing of connections [accompanied by] a specific feeling of abnormal meaningfulness".[3][4] He described the early stages of delusional thought as self-referential over-interpretations of actual sensory perceptions, as opposed to hallucinations.[1][5]
