Economist Steve Hanke explains it, Prof. Krugman: Ace of the Ad Hominem Smear
Prof. Paul Krugman’s New York Times column of March 27th, “American Thought Police,” made this startling assertion: “the hard right — which these days is more or less synonymous with the Republican Party — has a modus operandi when it comes to scholars expressing views it dislikes: never mind the substance, go for the smear.” What would Dr. Freud say? Well, after careful study of Prof. Krugman’s works and one trip to the couch, Dr. Freud diagnosed the patient and proclaimed, “projection bias.” Yes, the ace of the ad hominem smear is simply projecting his own attributes and habits of mind and deed to others.
