Beliefs and who are more susceptible...?

I did a research paper on cults for a Psychology class I did last semester. I was reminded of this study during the class discussion today. On the topic of beliefs, many think that someone cannot change your belief, influencing you to believe what they believe. This is in fact a falacy. Once you have adopted a belief that your belief cannot be affected by someone else's belief, you are in fact more susceptible to changing your belief into their belief. In my study, these are the types of people who were more likely to be inducted into a cult. The "never me", "I can never be brainwashed/influenced" attitude is in fact what causes you to fall prey to others influence. Viewing yourself as invincible and disregarding the possibilities is detrimental. However, knowing that anything is possible and being aware of the tactics are actually what guards you from being subject to adopting another's beliefs.
