Rationality Quote by Eliezer Yudkowsky
““We underestimate the power of science, and overestimate the power of personal observation. A peer-reviewed, journal-published, replicated report is worth far more than what you see with your own eyes. Our own eyes can deceive us. People can fool themselves, hallucinate, and even go insane. The controls on publication in major journals are more trustworthy than the very fabric of your brain. If you see with your own eyes that the sky is blue, and Science says it is green, then sir, I advise that you trust in Science. This is not what most scientists will tell you, of course; but I think it is pragmatically true. Because in real life, what happens is that your eyes have a little malfunction and decide that the sky is green, and science will tell you that the sky is blue.””
