Sadly, the forces of reason and logic don't have emotion on their side. And emotion is what drives people to battle. No one every rushed off into war thinking, "Hooray for logic! Down with emotional reasoning!" Rather, we are exhorted to fight the Kaiser, or terrorists, or Nazis or other "bad guys" who have the same emotional feelings about us.
So the game is rigged from the get-go. No rational person will blow themselves up with a suicide vest, or march into withering machine gun fire. So the emotional side wins, it seems, every time. Unless we can outsmart them, they will continue to win.
And that means everyone loses.
