As I looked back at my involvement with the Moonies, Lewin's three terms -- unfreezing, changing, and refreezing -- struck a chord in me. When I was first recruited, I experienced a meltdown of my personality. During indoctrination, I underwent a radical personality change. When my identity refroze, it was as if I had become a clone of our leader, Sun Myung Moon.
This aspect of cult indoctrination was scientifically demonstrated by Dr. Flavil Yeakley, a well-respected psychologist and a member of the mainline Church of Christ. He administered the Myers-Briggs Personality Type Inventory Test to 800 members of The Boston Church of Christ, a cult group led by Kip McKean. At that time, this cult was trying to recruit members of the mainline Church of Christ. I suppose the leaders agreed to participate because they may have thought they could gain credibility with the two million member mainline Church of Christ Churches.
The Myers-Briggs Inventory describes sixteen basic personality types. Whatever your type, it should remain the same throughout your lifetime. The major categories are Introvert/Extrovert, Sensing/Intuitive, Feeling/Thinking, and Judging/Perceiving. A questionnaire is filled out that reveals a person's preferences and disposition. For example, Extroverts are outgoing and feel comfortable with others. Introverts prefer to be with books, computers, and by themselves. People who are more Sensing are more practical (realistic), while Intuitives can be described as more innovative (following hunches). Other categories are Thinking (making objective, impersonal judgements) and Feeling (emotional, personal). Those who are considered to be Perceiving tend to keep things open ended and wait until the last minute to make a decision, while those who are deemed Judging like to reach closure quickly by choosing as soon as possible.
Yeakley did something that was very creative. He had the members fill out the Personality Type Inventory Test three times. They were instructed to:
1. Answer each question the way they would have before they joined the group;
2. Fill it out as present members of the group; and
3. Fill it out projecting five years into the future.
When Yeakley correlated the data of the first test, he found that before members joined the group, they varied widely in their personality types. In the second test, the members were moving towards one personality type. They were beginning to match the personality type of the cult leader of The Boston Church of Christ. The third test showed even an almost universal move toward the leader's personality type. As a comparison group, Yeakley administered this test to members of Catholic, Baptist, Lutheran, Methodist and Presbyterian churches and mainline Churches of Christ. There was no personality change before, during, or after they joined their churches. Yeakley published the results of this study in his book, The Discipling Dilemma, which is available free on the Internet.
Everyone has an authentic self. Although a healthy individual will grow and mature over time, his personality type should never change. Changes in personality type often indicate unhealthy social pressure that forces a person to act as if he were someone else. The results of Yeakley's study showed that cults create this kind of pressure. It also verified the existence of a cult identity which binds and gags the authentic self like a straitjacket. In my opinion, Yeakley statistically demonstrated the effects of destructive mind control techniques.
