Steven Pinker, in Conversation with Bill Gates on Climate Change

"When people subscribe to an ideology, they suck up evidence that supports their preconceptions and filter out evidence that goes against them.  Contrary to the belief of most scientists that denial of climate change is an effect of scientific illiteracy, it is not at all correlated with scientific literacy.  People who believe in man-made climate change don't know any more about climate or science than those who deny it.  It's almost perfectly correlated with left-wing versus right-wing orientation.  And a move toward greater rationality would unbundle them and let evidence inform what the optimal policies ought to be."
