I am convinced, based on more than three decades of studying NRMs through participant-observation and through interviews with both members and ex-members, that these movements have unleashed social and psychological forces of truly awesome power. These forces have wreaked havoc in many lives - in both adults and in children. It is these social and psychological influence processes that the social scientist has both the right and the duty to try to understand, regardless of whether such understanding will ultimately prove helpful or harmful to the cause of religious liberty. … the real sociological issue ought not to be whether brainwashing ever occurs but rather whether it occurs frequently enough to be considered an important social problem.
