, 4 June 2014 (UTC)  ::Because an author does not share your views, that does not mean the author is biased.  If a mathematician states that two plus two is four, and refuses to consider the possibility that two plus two is five, that does not prove bias.  Bias is a deliberate or unreasoning distortion of the facts to uphold one viewpoint over against another.  Bobbio, Cameron, and Goldthorpe have certainly studied the subject of political science in far greater depth than I have, and as best I can tell they have good reputations.  If you want to impeach them, it is not enough to say they disagree with you.  You need an academic source that says their views fail the standards of scholarly research.   23:33
