Cults are social groups with radical yet common belief in a goal, religion, idea, on any other unverifiable thing that can be taken to the extreme. its followers often living in an unconventional manner under the guidance of an authoritarian, charismatic leader. There are, however many meanings to what cults are and these are split into groups of positive, neutral, and negative connotations. Negatively connotative cults usually get the most media attention and these cults tend to negatively attack or veiw others outside of their social group for being different. Positive cults tend to still follow a idolized person or idea, but with no effect to outside discrimination, this can be like a Nudist colony because their ideal is based on positivist towards the earth.
Doomsday Cults: The term ‘Doomsday Cult’, coined by anthropologist John Lofland in 1966, encapsulates groups who make predictions about an apocalypse, and those who attempt to bring one about. 
Some modern examples of Doomsday Cults :
- The Church of Bible Understanding: a communal organization, teaching a form of evangelical Christianity.
- The People's Temple: In the 1950's Jim Jones started The People's Temple. 1971 the church was started being accused of fraud, and abuse against its members. Jones was increasingly paranoid because of this, as well as the fact that he was abusing prescription drugs. He decided to relocate to Guyana and build a 'socialist utopia' he called Jonestown. Many people followed him and began a new life at this camp. Former members of the church became worried for some friends who went to Jonestown, and talked a congressman into investigating the camp. When the congressman as well as a news crew arrived at the camp all seemed fine and well. However before they left members of the church asked for help getting back to America. Jones took this as an act of defiance and panicked. He ordered a firing squad to kill the people investigating the town. He then gathered everyone together in the center of the town and had them all 'drink the kool aid' which was mixed with cyanide. As a result over nine hundred Americans died.
