Using data from the ANES 2012 survey, I investigate the relationship between wordsum IQ estimates (unweighted sums, factor analytic and item-response theory scores) and opinions about nuclear energy and global warming and related beliefs. Proponents of nuclear energy were found to have somewhat higher IQs (103) than those who think we should have fewer (100) or the same as now (99). Surprisingly, IQ did not much much effect on belief in global warming (100.5 vs. 99.5), but it did show effects for the related beliefs.
