Here are the words of Steven Pinker, a non libertarian cited by the libertarian David Henderson and the libertarian think tank FEE:
smarter people are more liberal... But the key qualification is that the escalator of reason predicts only that intelligence should be correlated with classical liberalism, which values the autonomy and well-being of individuals over the constraints of tribe, authority, and tradition...
And now for a correlation that will annoy the left as much as the correlation with liberalism annoyed the right. The economist Bryan Caplan also looked at data from the General Social Survey and found that smarter people tend to think more like economists... They are more sympathetic to immigration, free markets, and free trade, and less sympathetic to protectionism, make-work policies, and government intervention in business...
...To think like an economist is to accept the theory of gentle commerce from classical liberalism, which touts the positive-sum payoffs of exchange and its knock-on benefit of expansive networks of cooperation. That sets it in opposition to populist, nationalist, and communist mindsets that see the world's wealth as zero-sum and infer that the enrichment of one group must come at the expense of another.
