I sometimes wonder if the next evolutionary step in human development is a branching off of those unable to "believe" in stuff on "faith" , from those more prone to superstition and "believing".
The Homo rationalis from the Homo stultus if you will.
I also wonder if at some point the Homo Rationalis would seek to delete the other branch, so as to prevent the extermination of the species through religious wars and hate based ideologies.
I suppose this would probably be perceived by the superstitious as fulfillment of end time prophecies, so of course homo stultus would not likely agree with the necessity of their demise.
This thread alone seems to indicate that there are two basic "types" of human, thinkers vs feelers, logical vs superstitious, free thinker vs follower, self-directed vs other-directed, and on it goes.
