No one is immune to propaganda, but if you also have little emotional intelligence you are extra vulnerable to it, because propaganda targets emotions, not facts.
Clever people get drawn into cult thinking all the time, and then get pushed farther in because people think that you need to be dumb to fall for it and mock the victims. All you really need to fall for scientology, zizianism or the black pill is to be lonely and vulnerable and for someone to come and tell you that you're an esteemed friend if you believe what they believe. Saying you're a part of any of these groups, to anyone outside of the cult, just tells us that you're really lonely and at one point you were willing to give up happiness and control of your life and emotions just to feel less scared and alone, and that's really sad.
