How many times do I have to explain?! "Facts" aren't enough, but that doesn't mean anyone is "lying"!
Receiving email like this is always extremely gratifying, of course, because it confirms for me that our "cultural cognition" research is indeed connecting with a large number of culturally diverse people. At the same time, it is frustrating to see how these readers fundamentally misunderstand our studies. I guess when you are so deeply caught up in a culturally contested question like this one, it is just really hard to get that screaming "the facts! the facts! Stop lying!!!," isn't going to promote constructive public engagement with the best available scientific evidence.
For Paul Krugman, it is the case that facts alone are always decisive, and in the case of those who disagree with him, it is the case that they are always "knaves & fools." Surely, too, his pointing this out (again) will generate reflective engagement with evidence on the issues by everyone who is exposed to his arguments. But if you are anybody else trying communicate with the public, my advice remains unchanged.
