From The American:
Who are smarter, liberals or conservatives? This is the kind of question that could spark fierce and endless debates between political opponents, but what if we could know, scientifically, that one side has the edge in brainpower? Should that change how we think about political issues?
Though few partisans on either side are likely to admit it, most people at one time or another have suspected that their political opponents are dim bulbs. Sometimes these sentiments get aired publicly, and both the Left and the Right have been guilty of leveling the “you’re stupid” accusation. Last summer, for example, conservative activists pushed the view that Supreme Court Justice Sonia Sotomayor, then a nominee, is an intellectual lightweight who lacks the brainpower to be an effective justice. But questioning the IQ of opponents is a specialty of liberals. When John Stuart Mill labeled British Conservatives “the Stupid Party” in the 19th century, he apparently started a long-term trend. Ronald Reagan, after all, was an “amiable dunce,” according to Clark Clifford and other Democrats. And when Vice President Dan Quayle told a 12-year-old student in a spelling bee that potato had an “e” at the end of it, Democrats milked the incident for all it was worth and then some. They even had the same student lead the Pledge of Allegiance at their 1992 convention.
