Is this “normal” behavior? Behavior that is indicative of a psychological disorder in some social and cultural contexts is perfectly normal, and thus not indicative of a disorder, in others. For example, in many contexts, intentionally injuring oneself physically is a sign of a psychological disorder. However, in the context shown here, it is not. Some adherents of Islam willingly harm themselves on the holy day of Ashura, as a way of commemorating an event in the early history of the religion. In general, claims that a given behavior reveals a disorder must be made carefully, with attention paid to the social, cultural, and historical context in which the behavior occurs.
