I'm having difficulty reconciling this claim with how I see American society judging the worth of political candidates. (Also in the journalistic outlets American society values the most.)
On the other hand, the article suggests that the more intelligent are more likely to be oblivious of their own biases and flaws (and where is that more likely than in politics), so on its own terms is not necessarily contradictory :)
Nobody will say "I want X but I'm not very smart so the politician who promises X is also not very smart and I won't vote for him."
