If you want to know whether there's any association between IQ and whatever economic or political theories, I would suggest to do a study that is designed for that purpose. Mining data from previous studies may give some hints but doesn't tell you anything firm. You need more specific paramaters and better constructed instruments.
One more time. My claim was that education levels are correlated with pro-market attitudes. To support that claim I linked to a paper that finds a strong correlation, stronger than with other parameters. As an aside, the paper also tries to refine the notion of education level by more explicitly pinpointing levels of ability. Clearly the number of vocabulary words that one knows from a given list is a way to measure a certain aspect of "education".
