According to a study published in the British Journal of Psychiatry and reported on by Reuters, comedians have an "unusual personality structure," scoring much higher than average on four psychotic personality traits: "unusual experiences" (belief in paranormality/psuedoscience), "cognitive disorganization" (an inability to...organize your thoughts), "introvertive anhedonia" (an inability to feel physical or social pleasure), and "impulsive non-conformity" (impulsive antisocial behavior). The most pronounced of which were comedians' high impulsive non-conformity and introversion scores.
