From the “It’s complimentary, so it must be true.” department – more educated people think like economists. And in fact, intelligence is the best predictor of belief in market mechanisms.

What does that mean?  Well, if the study is correct, in general, if you believe in the free market, are optimistic about future economic growth, don’t believe in “make-work” projects as economically valuable and believe that international free trade is overall a valuable benefit to the economy, you’re likely to have a higher IQ.  And the converse is true as well.
As a side note, apparently a large vocabulary is also a good proxy for intelligence.
