Disregarding what is intuitively obvious means the mind must continually repress the natural order of Life. Over time, this repressing causes the mind to think (against one's better judgement) thoughts that are inconsistent with Reality. So that the end result can be only madness.
When a large enough population in a society represses the intuitively obvious, the logical thing that must happen is a shift in mores and a decline in creativity. The society becomes volatile to the extent that chaos becomes the norm and mediocrity a virtue.
Given a large enough number of people, one can predict what will happen in a manner somewhat analogous to the chemical and physical laws that govern gas particles in a system. And a wise and competent leader will foresee all this and make plans accordingly.
It's true that all people have Free-Will, can make cause-and-effect decisions, as do separate atoms in a closed system. Yet as any chemist or physicist will tell you, atoms by themselves don't do much to their society alone. It takes billions of them to make an impact.
