(I'm sure there is a real name for the fallacy.) One sometimes hears, often in political arguments between opposed views where someone attempts a moderated stance, that "the truth lies somewhere in the middle." This may or may not be true; if one side is saying the equivalent of "2+2=4" and the other is saying "2+2=5", then the answer is not "somewhere in the middle." Likewise, if one side is saying the equivalent of "2+2=5" and the other is saying "2+2=6" then the answer is still not somewhere in the middle.
