I don't technically believe the literal word of the all sequences, but I to follow your general policy that if you find yourself disagreeing with someone smarter than you, you should just belive what they do

I agree, but I often find it hard to quantify peoples insight into specific areas, not knowing how much my judgment might be halo effect, and if I don't understand a problem properly I have a hard time telling how much of what the person is saying is correct/coherent. Mastery in knowing when to rely on others understanding, would indeed be an invaluable skill.

Edit: I just realized a prediction markets would give you that, if you would track statistics of users.
