“Each thinker will regard anything that clashes with his or her worldview to be insane and in conflict with reality. That’s because each thinker regards his or her worldview as reality itself and not as just an inner illusion. However, worldviews are just inner illusions. Making matters worse, people with similar worldviews tend to join with others who share major elements of their worldviews, and they tend to avoid those people who have worldviews that aren’t similar. This segregation results in confirmation bias among peers, making matters much worse.”
