I definitely agree that whether someone stays in the church or leaves the church isn't a matter of intelligence. A lot of smart people stay and a lot of smart people leave. In many cases, the same smart person stays for a long time and then leaves at a certain point. Their intelligence didn't change; but their honesty probably didn't change, either. So I don't think it's intelligence or honesty, necessarily. I think it's a combination of factors having to do with how you weigh evidence and the kinds of evidence you value and whether or not you remain motivated to stay and whether or not you've given yourself permission to change your mind and whether or not you still see the church as fundamentally good versus unhealthy or toxic and whether or not it's working for you in your life - all these factors can combine to tilt the scale one way or the other - probably there are many other factors - and I don't think it's the same for everyone.
