One of our measures found that the Drudge Report is
the most centrist of all media outlets in our sample. Our other
measure found that Fox News' Special Report is the most centrist.

It all depends on where the center is in your frame of reference. (Hint:
Everybody thinks his own view is balanced.)

There is a "statistical center" of political views that the Yale study
most likely used to determine their results. This has nothing to do with
what you or I believe, if it's done properly.

All this does is show a statistical center of an opinion, which by
definition is not necessarily correct.

In other words, "Garbage in, garbage out".
