A two-minute clip of Richard Feynman explaining why he considers much of social science pseudoscience. He stresses how easy it is to fool yourself and how much care real knowledge takes.

Why HN likes it: Commenters post it whenever a thread touches on soft sciences, replication problems, or what counts as real science.

“it's very hard to know something and you have to be really careful that you've done the work and aren't just deluding yourself”
