An interesting article in Slate in which a psychiatrist forces to live together 3 men who believe they are Jesus.
In the late 1950s, psychologist Milton Rokeach was gripped by an eccentric plan. He gathered three psychiatric patients, each with the delusion that they were Jesus Christ, to live together for two years in Ypsilanti State Hospital to see if their beliefs would change.
Surprise, but very little changes in the identities of the men.
