There are people that only think about making things better for themselves no matter how it effects others. These people would just use that “extra” intelligence to up their game. So no, I don’t think there would be less conflict.

I think you nailed it when you wrote " forcing their personal views and beliefs on others". That is what we see happening now with people trying to control others. We see it in government and with religion. It is trickling down to where the common person feels it is not only okay to do, but that they must do it to compete with others and get ahead.
