There are people who perceive facts and act accordingly and there are people who do not accept facts. Instead, they ignore facts and believe(?) that by repeating a falsehood over and over, it becomes real.
They do nothing material to change reality. They don’t invent, they don’t discover, they just pretend a blatant fallacy is factual.
Gravity is a fact. No matter how much I want to fly without mechanical assistance and no matter how many times I say “There is no gravity,” it does not change the effect of gravity by a single Planck–the smallest measurement of energy.
Society has learned how to orbit the earth, it has invented computers that can do millions of calculations per second AND fits in your pocket, and it has cured many formerly fatal diseases and injuries. All of these successes were built on facts.
Nevertheless, some people are happier with their preconceived notions, even when the facts are clear.
