Relationships and politics aren't the best examples - even the "experts" on all of these topics fail to demonstrate that they actually know what they're saying.

Relationships and politics aren't the best examples - even the "experts" on all of these topics fail to demonstrate that they actually know what they're saying. Even in topics like psychological research or evolutionary biology, people are willing to spout forth uninformed crap because they prefer their own "years of experience completing projects in the trenches against her psych lab any day." Dunning-Kruger is in full effect on HN, and it's a great argument for a liberal education. The depth of the ignorance and resistance to modern science here is somewhat shocking.
