The DSM – often referred to as “The Bible of Psychiatry” – lists over 300 (!) mental disorders.
Remarkably, I learned today, happiness is not one of them.
Turns out that psychologist Richard Bentall was as surpised as I am. So in 1992 he proposed to classify happiness as a mental disorder, because it is “statistically abnormal, consists of a discrete cluster of symptoms, is associated with a range of cognitive abnormalities, and probably reflects the abnormal functioning of the central nervous system.”
Moreover, according to Bentall, happiness reflects “a lack of contact with reality.”
I think he has a fair point.
