If you read the other FTBlogs (and you should), you may have noticed discussion of a study about cognitive ability, conservative ideology and outgroup prejudice. JT talked about it, and so did Jason. Basically, to read the coverage of the study, a team of psychologists from Brock University in Ontario have demonstrated that a lower level of cognitive ability is predictive of negative attitudes toward other races and gay people, but that political conservatism plays a significant role in that pathway. In a nutshell: conservatives are a bunch of hateful dummies, and now we can prove it!
While I would certainly love for that to be the case, I have spent far too much time wading in the muck of junk science about racism to hop so readily on board. I can certainly confess to my own non-trivial amount of outgroup antipathy toward ideological conservatives. Knowing what I know about confirmation bias and the difficulties associated with measuring intelligence (and how those exact same problems have been used to justifiably discredit studies of scientific racism), I suppressed my “nanna nanna boo boo” instinct and actually took my skeptical scalpel to the paper.
A link to the article, which may be behind a paywall for some of you, is provided here.
Hodson and Busseri note a connection between cognitive ability and prejudicial attitudes, noting that there is a predictive association between the two – people with poor cognitive skills are more likely to have negative evaluations of out-groups (including visible minorities and homosexuals). They also note the association between right-wing ideology and prejudice (and while they don’t mention System Justification Theory, we have seen a plausible mechanism for this connection before). They propose a model wherein depressed cognitive ability leads to an affinity for right-wing ideology, which in turn leads to out-group antipathy:
Many of you will recognize this type of model from our discussion of confounding from a couple weeks ago. Basically, what they propose is that it is not stupidity per se that makes you racist – instead, stupid people gravitate toward authoritarian belief systems, which in turn leads them to hate outsiders. It certainly passes the ‘sniff test’ – conservatism has a marked affinity for simple, “common sense” explanations, and a pronounced aversion to things like nuance or complexity in argument. It makes sense that some of that would result from difficulty actually processing multifaceted arguments. This could result in a tendency toward system justifying behaviours, which result in racist ideology.
If the proposed model is valid, what we should see is that the connection between cognitive ability and prejudicial attitudes (“c” in the above diagram) should disappear when we ‘control’ for ideology. This means that most of the connection between brains and hate is explained by conservativism.
In order to test their model, the authors conduct two tests. In the first experiment, they use longitudinal data from the U.K. that includes measures of cognitive ability, political ideology, and racial attitudes (as well as some important confounders). They analyzed these data according to the predictive model above, controlling for the socioeconomic status of cohort members and their parents (which helps control for childhood factors). In essence, they were able to capture data from thousands of Brits and test whether or not the findings conformed to their model.
In the second experiment, the authors re-analyzed data that had been collected in an American study that looked at prejudice against homosexuals as a function of abstract reasoning ability (how good you are at putting yourself in someone else’s shoes), right-wing authoritarianism, and frequency of association with gay people:
They undertook a statistical procedure called “path analysis” that, rather than loading all variables into the model at once, explicitly breaks out the effect of each potential confounder that might explain the connection between cognitive ability and prejudice. They were then able to examine authoritarianism independently from how many gay friends participants had.
The first study found that the data supported the model’s predictions in 3 of 4 cohorts (the effect was not seen in a cohort of women born in 1970):
Path C is the association between cognitive ability and prejudice, and as you can see from the table, there is a significant correlation. However, take a look at the right-most column. Path C’ represents the connection between cognitive ability and prejudice when ideology is controlled for. Remember the prediction above: if stupidity makes you conservative, and conservativism makes you racist, then the pathway C’ should disappear into non-significance. This is exactly what we observe in all but the final cohort (and even then, we see a moderating effect of controlling for ideology).
In the second study, we see the same pattern (the results are in the diagram above). When authoritarianism and out-group contact are controlled for, we see a decrease in the association between cognitive ability and prejudice – stupidity doesn’t do as good a job of explaining anti-gay hate:
Our results confirmed each component of the predicted model (see Fig. 2). Abstract reasoning negatively predicted prejudice, but this effect was significantly reduced when we included the mediators in the model. Lower levels of abstract reasoning also predicted greater right-wing authoritarianism, which in turn predicted elevated prejudice against homosexuals. Independent of these effects, there was a simultaneous indirect effect through increased intergroup contact: Individuals who had a greater capacity for abstract reasoning experienced more contact with out-groups, and more contact predicted less prejudice. [emphasis mine]
The data appear to support the hypothesis drawn by the authors: that people who are less able to grapple cognitively with complex and nuanced arguments will tend to form authoritarian/conservative worldviews, which in turn leads to out-group antipathy. As a result, when we think we see a causal line from stupidity to hate, what we are actually seeing is the indirect effect of a adopting bad (but cognitively easier) ideology.
So the question may be raised: are conservatives just more hateful people? My answer more or less matches what the authors say:
…conservative ideologies or value systems are not necessarily characterized by prejudice, and social conservatives do not “value” negative evaluations of out-groups. Instead, conservative ideologies contribute to negative out-group evaluations. Not only do cognitive abilities predict each of these constructs, but our analyses reveal that right-wing ideologies and contact with out-groups go a long way in explaining the relation between mental ability and prejudice. [emphasis mine]
I don’t think that all conservatives are hateful, nor do I think they are all stupid. Certainly some intelligent people have articulated conservative positions, and some folks who have called themselves conservative have made great strides to promote equality. That being said, there is a foundational flaw in the conservative position – the fundamental attribution error wherein people deserve what they get and nuance is a vice. With that mindset, it’s hard to see group differences as anything other than a threat to one’s perceived position of superiority.
All that being said, there are some pretty glaring omissions in this study that I think undermine the conclusions that the authors tried to draw from their findings. I will discuss some of those this afternoon.
