The only claim made in the hypothetical question was that either op-ed page could be used to become "informed about the realities of the current economic crisis". I was criticizing that assumption, not whether one was a better source of information than the other. Bias has to do with how we perceive the world. To say that data has a bias comes from a unique perception of fairness, not the data itself. To exclude relevant data to make a point, which these op-ed pages are notorious for, is a form of bias.
