The organization actively discourages utilizing critical thinking skills. Self-regulated analysis, reasoning, and judgement are only permitted within the confines of the current version Watchtower doctrine. As soon as your self-regulated reasoning hits that wall, the person only has two choices: 1.) cross that boundary (enter "apostate territory"), or 2.) reject your own reasoning, dismissing it for the logic imposed by someone else that runs contrary to what you've reasoned for yourself.
As a result, the WTS will naturally only attract and retain those who assign little value to, and do not often use, critical thinking skills. I'd argue that the demographic slice of the population which do not value or often use critical thinking skills will tend to have a higher percentage than average of those with less education, less awareness of social/bahavioral norms, etc.
I began to recognize in my childhood, that almost every "study" that came to a meeting was a complete weirdo. When I shared that observation with one of the more intelligent elders in the hall one day out in service, he replied with a laugh and said: "Have you heard this joke before? 'How is the Truth like a crescent wrench? Because it fits all the nuts!'"
How true it is!
