Intelligence versus attractiveness; is there a correlation?
Intriguing post by Satoshi Kanazawa at Psychology Today. He points out research that purports to show that intelligence correlates positively with attractiveness.
This research does dispel the notion that very attractive woman are less intelligent than average-looking woman; according to this research, very attractive woman are in the most intelligent group. I’m mulling over these findings; I don’t quite know what to think of this yet. I do know that I’m highly suspicious of any sort of simplistic IQ-based characterization of “intelligence” (I recently made that point here).
Kanazawa began this post pointing out the rampant prejudice that attractive people are more intelligent, but then argues that “virtually all stereotypes are empirically true.” I suspect that there is some truth driving many stereotypes, but I think his conclusion (that “virturally all stereotypes are empirically true”) is dangerous in its vagueness. Social feedback loops can cause stereotypes come true; if we mistreat people from stigmatized social groups, this makes it more likely that they will not do as well as social groups that have no such disadvantages. And even if it were true that there is some overall basis for most stereotypes, this doesn’t begin to suggest that we ought to make presumptions about any particular individuals.
Intelligence Quotients are not the only flawed idea. Attractiveness is greatly influenced by culture.
additionally, experiments from several years ago indicate that physically attractive people are perceived to be better than the less attractive, and are judged less harshly.
One experiment involved a number of short essays, all actually penned by the same person. The essays intentionally contained several technical and factual error, and the test subjects were each asked to assess the essays for an essay contest.
A control group received copies of the essays without a photo. The test group members each received copies of the same essays with photos of a child (presumably the author of the essay) attached. For each test subject the photos were shuffled and attached to different essays.
The control group identified the various errors consistently. The test group showed a tendency to miss errors when the essay was accompanied by a photo of an attractive child, while assessments with the photos of the less attractive children were more like the control group.
Niklaus: Point well taken. There do seem to be some universals underlying societal judgements of attractiveness. Consider this compelling demonstration of the power of symmetry, for instance.
Where cultural conceptions of beauty differ tend to be very changeable traits, such as dress and bodily modification (make-up, foot binding, corsets, etc). There does appear to be some deeply-set, natural preferences for objective beauty. Babies stare much longer at faces deemed more “attractive” by adults; staring time has long been interpreted in babies as a sign of preference. See here.
Of course, there are many somewhat impotent attempts to link attractiveness with intelligence. For instance, there is the relatively new notion that hippy women store more omega-3 fatty acids in their bodies, which will in turn result in smarter babies- thus curvy women are more attractive (see here).
At this point, the interpretation is iffy at best. Perhaps the media and the lay public enjoy such links because it justifies our natural preference for the cute? Attractive people are always rated as more intelligent and capable than their homelier fellows.
