It's fascinating to me how tech-related discussions are on point here and this site is a gem, but regarding other topics, they tend to get off the road fast and hard, especially social sciences.
I visit HN every day because I am a geek at heart that loves machines since childhood and then I studied people (Economics, Psychology, etc). We know that technology is queen right now and you are on top of the world. Almost everyone here is way, way smarter than me and I know that, but knowledge in one field, no matter how important or powerful it is (like tech right now), does not translate into others, especially social sciences, human behavior, and the like. Despite that, the hubris and the "I'm better than you" attitude on these topics are astonishing.
I love this site, it's really a gold mine of very sharp people and responses, just not on some topics.
