A cult is a social group that often has beliefs or practices that are considered outside the mainstream. Members typically follow a charismatic leader and may be encouraged to isolate themselves from outside influences. Cults can vary widely in their beliefs, ranging from religious to political ideologies. Cults often use psychological manipulation to maintain control over their members. This can include techniques like emotional abuse, fear tactics, and strict rules governing behavior. Some well-known examples of cults include the People's Temple, led by Jim Jones, and the Branch Davidians, led by David Koresh.
