I think your view here may be a little more pessimistic than mine. I don't think the majority is opposed to critical thinking, although I think most people are bad at it. I also think most people are bad at civil and effective communication, so you may get toxic communities even from well-meaning people. I'll be interested to see what happens. You may be right that communities will select mods that create echo chambers. I'm a little more optimistic. Whichever way it goes, I think the ability to experiment (e.g. with weighted or modified voting schemes) with this sort of mechanic is definitely worth pursuing.
