For people who have never been in contact with cults, these destructive groups may exert some kind of morbid fascination. Secretive, isolating and hierarchical, these structures appear difficult to escape. But how do people end up in cults in the first place?

A lot of literature has been dedicated to how cults recruit and operate, but despite years of research, scholars do not entirely understand the psychology of victims, and why they end up being trapped.

Men and women who join cults are often unaware of it until it is too late, and they are isolated from everyone they know. They become dependant on the group, which feels like the only perceived safe place – but also paradoxically like a source of threat.

In order to stop people from getting trapped into dangerous groups, research will have to focus on two questions : who is more likely to join? And more importantly, how can people recognise they are being pulled in?

During a transition-time

One of the problems is there is no real consensus on whether cult victims have a typical 'psychological profile'.

"There is a failure to find a profile of a cult victim, despite many scholars looking for such. However, prominent scholar Margaret Singer found that people in a "normal life blip" such as a normal transition - to or from university, a job, a relationship, and other kinds of normal life changes - seem to be more at risk", Alexandra Stein, who specialises in social psychology of ideological extremism, told IBTimes UK.

Her insight is particularly interesting because she herself was part of a political cult in the United States, years ago. Looking back on her experience, she says one of the push factors into the group was the fact she was experiencing important changes in her life at the time. She had just broken up with a boyfriend, and because she was idealist, she wanted to meet people who fought for social justice.

A question of ideology?

Though it is difficult to generalise, idealism is often a common characteristic shared by cult victims. "These people are often idealists, they think they will make a difference to humanity, or that they will best serve their God or their ideals within the group. Individuals who are recruited are also often young adults in the middle or upper class", Robert Pardon, director of the New England Institute of Religious Research, told IBTimes UK.

However, looking at what draws people in only in terms of personality or ideology would be too simplistic. "Individual are holistic beings. They don't just join because of ideology, they go in it for the feeling of worthiness, of belonging. Sometimes they don't even understand what the theology of the group really is about", Pardon adds.

Raising awareness and recovering

Victims' stories all are chilling reminders that dangerous groups also rely on sophisticated techniques to recruit their members.

"Cults use elaborate techniques to break individuals down mentally and physically. We have identified 26 of these techniques. The process of recruitment can be very quick, it is not uncommon for victims to become trapped in just three to four days" Ian Haworth, general secretary of Cult Information Centre told IBTimes UK.

Some experts believe it is in fact more useful to identify common recruitment tactics rather than to focus on victims' psychological traits.

It is important to recognise for example that a cult will try to separate its members from friends and family. "If a group or an individual tries to isolate you from all your previous relationships, you can start worrying", Stein says.

Though it is not enough on its own, having strong relationships can offer a form of protection against cults.

"A victim will go through a sudden change in personality that is called 'snapping'. After snapping, the person ceases to be who he or she was, and becomes entirely consumed by the group. All they do then is not in their own interest, but in the interest of the group", Haworth says. Families and friends can help by researching the group as quickly as possible. If it turns out to be a cult, then they can warn a person before they are trapped.

Learning from experience

For victims lucky enough to escape, the process of recovery can be long and arduous, with people experiencing feelings of guilt, confusion, depression or disorientation which can last for about a year.

When victims do get better, raising awareness around them often becomes a priority. "The important thing is teaching how these organisations work, what is happening in the relationship between members and leader, and why people were successfully isolated. This should be done early, during school years. We have to educate everyone about the fact that it is dangerous to end up in isolating and hierarchical relationships", Stein concludes.
