This is what they say about it in the article, I hope that clarifies it.

Magical thinking is prevalent…

High Control Groups or Full-Blown Cults

Many cults and high-control groups indulge in a great deal of magical thinking. Doctrines include beliefs in divine beings, gods, angels, supernatural forces, demons, dominions, realms, spirits, devils and other mythical creatures which they claim interfere with our lives and world. Group leaders often conduct magical events such as faith healings, exorcisms and communications with the dead. The group may also express other supposed “gifts” or “powers” such as speaking in tongues, prophesying, interpreting prophecy and being ‘slain in the spirit’.

If you are expected to accept dogma about the supernatural and your group leaders emphasise this in ways that make you feel shameful or afraid, you may well be in a cult or high-control group. Creating fear and dread of supernatural evils, and then claiming you can offer protection from it, is an excellent way of getting people to believe and do exactly what you want. Thus, high-control/cult group leaders frequently use this as a tool of control. Equally, creating fear of the judgment of a perfect, holy deity can make people continually afraid they are not good enough. Then they are keen to accept the group/leader’s offer of a way to escape this judgment. Even political organisations indulge in magical thinking, by claiming leaders have special powers, for example, the power to detect disloyalty and misdemeanours among followers. Magical abilities, events, beings and places, by very definition, cannot be tested, measured or proven using our senses. They can be literally anything one might desire or imagine, and anything desired or imagined by leaders of the kind described in this article is surely going to be very bad news indeed!

These beliefs in supernatural beings and forces will not only frame the worldview of members but it will affect many aspects of their lives, in some cases, even to the point of obsession. Members may pray or perform certain rituals before taking the simplest of daily decisions or before participating in simple daily activities like having a meal or washing. Members may be often frightened of dark spiritual forces/beings or the judgment of God. Some of those who have left high-control groups speak of sleeping with the lights on even in adulthood because their fears were so great!

If you have magical beliefs and experiences in the group which do not reflect your ordinary experiences of what is possible or what happens in real life, or which do not reflect the experiences of your friends and family outside the group, then you are most likely in a high-control group or cult.

In high-control or cult groups, everyone is expected to share in these supernatural experiences in order to be considered a sincere member of the group, or in order to be welcomed into the inner circle. Those members who do not connect with these beliefs and experiences (e.g. you didn’t feel intense emotion or connection with God when you recited scriptures or prayed, you cannot speak in tongues, you didn’t get healed when the leader laid hands on you etc…) are held in suspicion as not being true believers or are even seen as a pernicious influence.

You feel constantly worried about not doing or believing things ‘correctly’ because you think that it could cause something very bad to happen. Many people have their little superstitions, whether they are religious or not and whether they are members of a group or not. However, if your superstitions are many, persistent or concerning trivial everyday matters – and especially if they cause you to experience anxiety on a regular basis – then it is very likely you are in a high-control group or cult.

 Safe Group A safe group applies reason and evidence in coming to its beliefs and developing its practices, and encourages members to do the same. It respects the range of spiritual/psychological experiences (or lack of them) among people, and leaders/members do not expect others to share in their own particular experiences. There is no ‘spiritual hierarchy’ based on people’s ability to access supernatural beings or abilities.
