Paul Krugman points out what cognitive research has shown, that denial of scientific facts — and their implications — is strongly correlated with an authoritarian mindset, one that many far right republicans exhibit.
Grand Old Planet - Paul Krugman
What accounts for this pattern of denial? Earlier this year, the science writer Chris Mooney published “The Republican Brain,” which was not, as you might think, a partisan screed. It was, instead, a survey of the now-extensive research linking political views to personality types. As Mr. Mooney showed, modern American conservatism is highly correlated with authoritarian inclinations — and authoritarians are strongly inclined to reject any evidence contradicting their prior beliefs. Today’s Republicans cocoon themselves in an alternate reality defined by Fox News, Rush Limbaugh and The Wall Street Journal’s editorial page, and only on rare occasions — like on election night — encounter any hint that what they believe might not be true.
And, no, it’s not symmetric. Liberals, being human, often give in to wishful thinking — but not in the same systematic, all-encompassing way.
You may have read about the recent study from the Congressional Research Service finding no empirical support for the dogma that cutting taxes on the wealthy leads to higher economic growth. How did Republicans respond? By suppressing the report. On economics, as in hard science, modern conservatives don’t want to hear anything challenging their preconceptions — and they don’t want anyone else to hear about it, either.
