>> Facts the web unanimously agrees on are considered a reasonable proxy for truth. Web pages that contain contradictory information are bumped down the rankings. But if there are contradictory sites then the web is not in unanimous agreement, is it? Something about this statement bothers me. Is there no chance that the web could be in "unanimous agreement" about something which is wrong? Seems to me that human populations make this mistake quite often, and since it is humans (for the most part) who write the web the same fallibility should show up there.
