Jerusalem Syndrome: (Self-)Selection Bias
This psychiatric syndrome is specific to tourists in Jerusalem
This month's issue of Wired magazine has an interesting look at Jerusalem Syndrome, which is one of those fascinating, location-specific psychiatric conditions. In Jerusalem Syndrome, a tourist who visits Jerusalem is overcome by religious fervor. In advanced cases, the sufferer may actually believe themselves to be the Messiah.
Frequently, an in-patient stay at a psychiatric facility is able to repair this specific sort of psychotic break. But the most effective treatment is to send the patient back to their home country, to their everyday, familiar and neutral turf. Needless to say, psychiatrists and therapists in Jerusalem are all highly trained and experienced in spotting and treating cases of Jerusalem Syndrome.
