Cognitive dissonance is a powerful drug. It makes otherwise-very-intelligent people goofy and incoherent in their thinking and blinds them to certain realities that they should normally see right in front of their noses. I witness it all the time in the field of economics — a key piece of logic, a key fact that certain people absolutely refuse to take into account simply because they have a singular idea of how the world works and they cannot allow that idea to ever come into question. They would rather leap into a mental gymnastics routine worthy of an Olympic gold medal than examine the truth. And if you confront them on it, they’ll accuse YOU of being the one in denial.
