What is your Myers-Briggs personality type? If you're unfamiliar with it, you can take a test here: http://www.humanmetrics.com/cgi-win/JTypes2.asp
Be warned that the test can be wildly inaccurate. You might do better to look at a brief description of each type and figure it out that way. You can do that here: http://www.myersbriggs.org/my-mbti-personality-type/mbti-basics/
In Combatting Cult Mind Control, Steve Hassan says that cults try to mold all their members toward becoming one particular type. I believe that JWs are strongly encouraged to be Sensing Thinking Judgers.
I think they're kind of schizophrenic about whether they want their members to be Extraverted or Introverted. Extraverts are more likely to engage in the field service and give talks; Introverts are more likely to spend time reading the publications and isolate themselves from others.
I think they want Sensors who are good at focusing on practical tasks, rather than iNtuitives who like to ponder abstract concepts.
I think they want Thinkers, who are more likely to hold to a given set of values, rather than Feelers who make decisions based on emotion and are more likely to ignore directives like shunning family members.
I think they want Judgers who are more comfortable having the structure of an organization and believing in firm conclusions, rather than Perceivers who are more comfortable being spontaneous and keeping their options open.
Of course, people of all personality types can become victims of a high-control group.
I am an INFJ. iNtuitive Feelers tend to be on a constant quest for spirituality and/or higher meaning, which is certainly true for me. We tend to be more vulnerable to groups that claim to have the all answers to life.
What type are you?
