Mensa accepts people in the top 2% of standard intelligence test. In a normal distrubution, with a standard deviation of 15, you would have to score more than 2 standard deviations (score 130) above the mean in order to qualify since only 95% of scores are represented within 2 standard deviations of the mean and that would leave 2.5% on the right end tale. So, I'm more than 2 standard deviations above the mean, but not quite there. :(
It's kind of hard to even comment on this thread without sounding like an as which I think I kind of did. (I posted what literally went through my mind while considering the OP. What a nerd.) But, I would be willing to bet that there would be a greater percentage of of EXJW Mensa members than JW Mensa members.
That said, my earliest complaints about the religion were that something just didn't make sense. I knew there was something wrong, but I didn't know much about logical fallacies as a teenager. I left at age 19, but didn't know TTATT until years later as the internet began blossoming. When I had the intellectual tools, I could finally put it all together.
The religion really just doesn't make sense. It also takes some personal honesty to admit that, which is another issue altogether.
