So long as everyone is just arrogant enough to assume that their own reasoning is pretty darn reliable, this problem will persist.

I enjoyed reading you post, and agree with what you say but for one aspect. One is not arrogant for believing one's reasoning is reliable, that is a necessity and a consequence of reasoning itself.

The problem (if there is one...) lies in other areas, mostly in how much one weights each fact involved. That is where culture and beliefs come into play, and it's this differential value that allows for disparate, but valid, reasoning.
