If no one is willing to define what "blind adherence" means then it's hard to determine if there's a correlation, as you suggest.

Based on the conversation so far, I interpret it to mean "someone who believes something other than what I believe, and for reasons I don't agree with."

Perhaps the best solution might be to invert things, but I have been unable to find a list of out-of-the-box thinkers. Mostly I find people claiming to be so, without providing any external evidence.
