Deprogramming is a controversial tactic that seeks to dissuade someone from "strongly held convictions" such as religious beliefs. Deprogramming purports to assist a person who holds a particular belief system—of a kind considered harmful by those initiating the deprogramming—to change those beliefs and sever connections to the group associated with them. Typically, people identifying themselves as deprogrammers are hired by a person's relatives, often parents of adult children. The subject of the deprogramming is usually forced to undergo the procedure, which might last days or weeks, against their will.
