++Addition++Razib hypothetically describes why liberal Republicans are duller than their co-partisans:
Someone who was born into a “Republican family,” and doesn’t reflect much about ideology and so continues to vote Republican despite being liberal. I don’t feel I need to explain conservative Democrats, as it seems to me that political exemplars of this class are generally duller than liberal or moderate Democrats.
Regarding the latter remark, I think he is essentially pointing to the South (the US’ least intelligent region).
In considering a previous post, Razib points to a couple of historical instances of a prototypical whiterpeople/NAM coalition. He also references a previous post showing the average intelligence of white conservatives and white liberals to be similar. The latter (which might be a little dated) presents an opportunity to force whiterpeople on the left to acknowledge human biodiversity as a prerequisite to basking in their elevated sense of self-worth.
The estimated average IQ by political orientation*, based on Wordsum scores of GSS respondents between ’04 and ’06, for men and (women)**:
|Party ID||Average IQ|
Republicans are more intelligent. If only whites are considered, things look a little brighter for whiterpeople:
|Party ID||Average IQ|
In the aggregate, there is little apparent relationship between intelligence and party identification among whites, other than self-styled independents being less intelligent than either Democrats or Republicans, a pattern that is also apparent among moderates in comparison to liberals and conservatives.
It’s not partisanship but political ideology that whiterpeople are more inclined to embrace as a symbol of greater enlightenment (or intelligence), however. Consequently, it is along the liberal-conservative spectrum where whiterpeople must dispense with blank slatism in order for their (slight) intellectual advantage over conservatives to become apparent.
Average IQ by political ideology for men and (women) of all races who were GSS respondents between ’04 and ’06:
And for whites only:
Self-identified white liberals are, on average, more intelligent than self-identified white conservatives are^, but without considering race, conservatives and liberals are basically at cognitive parity.
Summarizing from above, two things are seen: 1) Republicans have higher IQs than Democrats do, while white Republicans and white Democrats have similar IQs; and 2) Liberals and conservatives have similar IQs, while white liberals have higher IQs than white conservatives do. This results from the fact that although they proxy fairly well for one another, “conservative” does not equal “Republican”, nor “liberal” equal “Democrat”.
So are self-described liberals from both parties more intelligent than their conservative co-partisans? No. Inline with the trend of those in the squishy middle being less intelligent than those on either end of the spectrum are, conservative Democrats are less intelligent than liberal Democrats are, and liberal Republicans are less intelligent than conservative Republicans are.
Since this requires looking at 49 different categorical placements for a body of respondents from ’04 to ’06, to ensure samples of at least fifty, average IQ for men and women are not separated. Average IQ for all races by political orientation within each of the the two major parties:
* The GSS lists three degrees for each side by political party orientation and also by political ideology (seven total categories for party and also for ideology). I’ve condensed them to three for ease of comparison in both sets of tables. The IQ conversion from Wordsum scores is based on the presumption that the white average is 100.
** Women have stronger verbal intelligence than men do. They are also more likely to be Democrats than men are. Consequently, not controlling for gender artificially inflates the apparent average intelligence of Democrats relative to Republicans when GSS data are being used.
^ At least the GSS suggests as much. However, the GSS’ proxy for intelligence is a verbal measure. In academia, emphasis on verbal intelligence and leftism go together–disciplines where mathematical and visuo-spatial abilities are more heavily rewarded (engineering, computer science, business) are less leftist in orientation.
