One of the Reuteurs blogs has a somewhat rambly post about being wrong in journalism which does, however, contain this absolute gem:
I try hard to believe the opposite: that many if not most of my opinions are wrong (although of course I have no idea which they are), and that many of the most interesting and useful things I write come out of my being wrong rather than being right. This is not, as Wilkinson noted to Cowen, an easy intellectual stance to hold: he calls it “a weird violation of the actual computational constraints of the human mind”.
