No, arijo, biohacker42 didn't say anything close to "rational discussion focused on discovering objective truth is just a waste of time". It's just your idea, and a stupid idea to boot. I downvoted both of your comments accordingly.
Disussing dogma is a waste of time and energy. Economic decisions should focus on solving real people problems in pragmatic terms (in an agile way if you wish). Elaborate intellectual theories, though eye-candy, do not stand on firm reality grounding (think of Locke's madman concept - one who makes impeccable and rigorous reasoning based on flawed data and assumptions). That's all I was trying to express in my comment above.
