Let's look at America's scIQ: In 2006 the General Social Survey asked 437 respondents eleven basic science questions. The first one, for example, was whether the earth's center is hot. I gave each person one point for answering a question correctly, and then summed the scores. My next step was to convert these totals so they resemble IQ scores. I set the white mean at 100, and the standard deviation at 15. Here are some averages:
ScIQ mean scores
Less than high school 82.4
High school 94.2
Junior College 96.8
Never attends church 101.1
Attends more than once a week 87.4
New England 101.4
Middle Atlantic 98.0
East North Central 96.8
West North Central 103.6
South Atlantic 92.8
East South Central 95.7
West South Central 94.3
Interesting stuff. Blacks are well over one standard deviation below whites. This doesn't quite square with all the black doctors and scientists we see on TV. Women are about one-third of a SD below men--score one for Larry Summers.
Educational degree is no surprise; neither is the high Jewish mean. Anyone who completes high school should have been exposed to the information needed to answer the questions correctly. Many of those who finished high school and even attended college missed some of the questions, indicating that people are not understanding or retaining the information.
ScIQ differentiates churchgoers from non-attenders better than IQ does. I calculated Pearson correlations between scIQ and church attendance, and then the latter with IQ: the estimates are -.26 and -.08, respectively. Scientifically-minded people are less likely to go to church than people who are smart in a more general way, which supports the notion that there is intellectual friction between science and religion. By the way, scIQ correlates with IQ at .46.
It is also interesting that the West North Central region (Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota and South Dakota) is at the top of the scIQ list, considering that New England tops the IQ list based on GSS data. Is it all the nerdy white folks who live in those parts? The uncool Mountain States are not far behind.
