Who do you know who's genuinely not political? People have biases all over the place. They're not going to disappear - understand them, acknowledge them, interpret them. Don't just shrug your shoulders and say "nah I don't like that". They're not publishing opinion pieces - it's research.

While you might want to make this an ad hominem attack, all I can say is that my probability estimates are pretty darn bipartisan.
