The illusion that I see the world clearly (due to my logic and objectivity), while those who disagree with me don’t (due to irrationality, bias or lack of knowledge). “If I could nominate one candidate for “biggest obstacle to world peace and social harmony,” it would be naive realism because it is so easily ratcheted up from the individual to the group level: My group is right because we see things as they are. Those who disagree are obviously biased by their religion, their ideology, or their self-interest. Naive realism gives us a world full of good and evil, and this brings us to the most disturbing implication of the sages’ advice about hypocrisy: Good and evil do not exist outside of our beliefs about them.” – Jon Haidt, The Happiness Hypothesis
