Does this prove Conservatives arre less intelligent?

Conservatives exhibit less cognitive ability than liberals do. Or that's what it says in the social science literature, anyway. A 2010 study using data from the National Longitudinal Study of Adolescent Health, for example, found that the IQs of young adults who described themselves as "very liberal" averaged 106.42, whereas the mean of those who identified as "very conservative" was 94.82. Similarly, when a 2009 study correlated cognitive capacity with political beliefs among 1,254 community college students and 1,600 foreign students seeking entry to U.S. universities, it found that conservatism is "related to low performance on cognitive ability tests." In 2012, a paper reported that people endorse more conservative views when drunk or under cognitive pressure; it concluded that "political conservatism may be a process consequence of low-effort thought."
