The less intelligent and uneducated really don’t tolerate unpopular views

Filed under: Free Speech,GSS — Razib Khan @ 7:10 am

When looking at the General Social Survey one of the most striking things is how much more the more educated and intelligent are in terms of accepting unpopular views. Since 2008 and the SPKMSLM variable has asked about anti-American hatred preached by Muslim clerics in the United States:

… consider a Muslim clergyman who preaches hatred of the United States.

If such a person wanted to make a speech in your community preaching hatred of the United States, should he be allowed to speak, or not?

The ideological breakdown is what you’d expect it to me, and tolerance for this sort of speech is low, at about 40% of Americans.

  

In case you are wondering, the impact of intelligence still matters after you correct for education. I ran a quick & dirty logistic regression, and you can see that below (in case you care, being a woman is associated with less tolerance for free speech here, and political ideology doesn’t matter much once you take into account religiosity):

Most liberals and smart people want racists to be allowed to speak

Filed under: GSS — Razib Khan @ 12:44 am


Over the past year or so there have been many worries that liberals are backing off from their support for free speech. Even mainstream figures such as Howard Dean have started to chant the mantra “hate speech is not free speech”. And then you have op-eds from professors such as When ‘free speech’ becomes a political weapon.

But whenever I look at the General Social Survey I see no great change in support for free speech in terms of the patterns. Perhaps something has changed in the year 2017, but I think what we are seeing are vocal and motivated minorities who are drowning out liberal (in the classical sense) majorities.

The GSS has a variable, SPKRAC, which asks:

…consider a person who believes that Blacks are genetically inferior. a. If such a person wanted to make a speech in your community claiming that Blacks are inferior, should he be allowed to speak, or not?

The plot at the top of this posts shows that the GSS sample respondents exhibit almost no change year to year on this question.

The GSS also has a variable, SPKMSLM, which asks:

Now consider a Muslim clergyman who preaches hatred of the United States.

If such a person wanted to make a speech in your community preaching hatred of the United States, should he be allowed to speak, or not?

This question has been asked since 2008, and only a minority would allow this person to speak, 41-43 percent.

Let’s break this down by ideology and intelligence from the year 2008 onward. The GSS has a variable, WORDSUM, which is a vocabulary test. Respondents receive a score from 0 to 10 (correct). I combined 0-4 as “not smart”, 5-6 as “average”, 7-8 as “above average,” and finally 9-10 as “smart.”

Also I limited the sample to non-Hispanic whites to compare “peaches to peaches.”

What the above plot shows is that liberals support free speech for both racists and Muslim radicals. Conservatives are more skeptical of free speech for both groups, but especially the Muslims. You might be curious why moderates seem so skeptical of free speech. That’s because on average moderates are less intelligent than people at the ideological poles, and the less intelligent are generally less supportive of heterodox speech (I suspect it’s because they are too dumb ever to come up with an original and transgressive idea).

But don’t take my word for it.

 

It’s a very robust pattern that the less intelligent are skeptical of deviant thought. I think it’s partly because they can’t empathize since they don’t have many thoughts.

Below is a table which does a cross-tab of views on speech for racists and Muslims (again, for non-Hispanic whites after the year 2008). You can see ideological and intelligence distribution for various positions. Conservative anti-Islamic and liberal philo-Muslim tendencies are on display. The less intelligent are overrepresented among the censorious.

Millennials with college degrees don’t favor censorship

Filed under: Censorship,Culture,GSS — Razib Khan @ 4:00 pm

There’s a specter haunting the academy. The specter of “red guards” destroying lives and tearing down Western civilization and all its accomplishments in the interests of antinomian leveling impulses through denunciations and purges. (here is the latest instance; the whole thing leaves me yawning, because too few people have the courage or gall to stand up for what they know is right, so this will happen again and again and again)

I am plain in my view that this is a problem. Some of my friends in the academy agree, but in the end they make different choices about priorities. Others don’t think this is a problem at all (and honestly, they clearly think that free speech is more about speech that they think is acceptable). Ultimately I don’t think that this will end well; I’m most certainly going to be on the other side of people whom I consider friends if and when the end of our current liberal democratic order collapses of its own contradictions.

But this isn’t about that. Rather, it’s about an aspect of it: are Millennials, those born after 1980, who go to college more opposed to freedom of speech than previous generations? Is this what’s driving the flair up of campus events? The answer, as clear in the GSS is that Millennials who have gone to college are not more censorious.

The GSS has a variable, SPKRAC. It asks:

…. consider a person who believes that Blacks are genetically inferior. a. If such a person wanted to make a speech in your community claiming that Blacks are inferior, should he be allowed to speak, or not?

Should this person be allowed to speak? As you can see above there is hardly any difference between people of different generations if they have a college education on this question.* The big difference is between generations among those who have a high school education or less. I think this is simply due to the reality that if you have only a high school education as a Millennial you’re much more likely to be not very intelligent in relation to older generations. The slight decline for college educated Millennials might be due to this effect as well, and more marginal kids are now going to, and finishing, college.

If you do a logistic regression in the GSS you see what I have reported earlier: both education and intelligence have independent and notable impacts predicting support of free speech to a liberal extent. Being a woman usually correlates with lower tolerance of deviant or abhorrent speech. Socioeconomic status, income, and age, don’t really matter too much when other variables are accounted for.

What about politics? The results might surprise you.

As you can see on the whole liberals are the most supportive of free speech for racists. It does look that there has been some regression since the real “greatest generation.” And as I expected moderates are the least tolerant.

Moderates are usually less intelligent (this is easily confirmed with the GSS) and informed, and they’re conformists. Today racism is in bad odor, so their instinct to ban or restrict it is strong, as opposed to the abstract principle of free speech. This impulse probably explains the declines broadly among Millennials.

But the results at the top indicate that university education may actually inoculate a bit against this! (remember, it’s not just intelligence, as university education had an independent effect on opinions in the regression)

There’s something going on. It’s a problem. Perhaps a big problem. I do think it ultimately threatens the credibility of the academy in a way we haven’t seen in generations. But it’s not because the majority of students agree with driving speakers they don’t like off the campus or banning speech they find hurtful. A minority of students are loud, mobilized, and active. Sometimes minorities can shape history….

* I limited the sample to non-Hispanic whites. I used the variables SPKRAC, COHORT and DEGREE. I recombined some. E.g., COHORT(r:1800-1945″pre-Boomer”;1946-1964″Boomer”;1965-1980″GenX”;1981-*”Millennial”). Adding groups besides non-Hispanic whites didn’t change the qualitative result, though support for free speech declines among minorities.

It’s been a while since I’ve done much GSS blogging. Part of it is that I’ve got only so much attention I can devote to things, and most of my focus has been on the area of science that I’m interested in, and one or two non-scientific topics. The second variable is that I started blogging about GSS data a long time ago (~2008), and there’s only so much interesting stuff you can talk about.

But over the past few years there have been some controversies related to speech in public spaces, and what is and isn’t acceptable. There has also been some chatter that young people today in particular are intolerant of freedom of speech. I’ve wanted to address this, so here I go.

The toleration of racists is in today’s America is like testing a boundary condition. If you are willing to tolerate racist speech if you are not a racist, then you are pretty likely to be a free speech absolutist. I am not interested in rehashing arguments, I support free speech in an absolutist sense personally. Rather, let’s look at some data.

The General Social Survey has a question up from 2014 for the variable RACEMEET that asks:

Should people prejudiced against any racial or ethnic group be allowed to hold public meetings?

The question was asked in 2010 and 2014, and 2,651 individuals answered this. The answer was converted to ordinal, so I decided to probe relationships between variables and the score of toleration through regression. Some independent variables, such as political viewpoint (POLVIEWS), were recoded in an ordinal fashion (so that “extremely liberal” = 1, “liberal” = 2, and so forth, to “extremely conservative” = 7). Others, such as age, do not require any recoding. RACEMEET itself was converted to an ordinal.

The above results suggest that political ideology does not predict your response to this question much once you account for other variables. In fact, I did a query on ideological views first, and the results indicated to me what was really going on.

  EXT. LIB. LIB. SLIGHTLY LIB. MODERATE SLGHTLY CONSERV. CONSERV. EXT. CONSERV.
1: Should definitely be allowed 39 24 17 15 22 17 20
2: Should probably be allowed 12 24 24 21 22 22 15
3: Should probably not be allowed 26 20 19 22 19 24 22
4: Should definitely not be allowed 23 32 40 43 37 38 43

As you can see moderates are relatively skeptical of allowing racists to have a public meeting. All of my analysis of the GSS indicates that moderates are not as smart as more liberal or conservative people.

Let’s go through the variables which were significant predictors above. First, sex.

Male Female
1: Should definitely be allowed 21 13
2: Should probably be allowed 22 21
3: Should probably not be allowed 20 23
4: Should definitely not be allowed 36 43

These results were expected. On the whole women tend to be more skeptical of absolutist free speech positions which allow offensive material to be promoted (women are more skeptical of allowing Communists to speak too in comparison to men, so it’s not because of the ideology of the speaker or viewpoint).

Then church attendance frequency:

Never attends church More than once a week
1: Should definitely be allowed 20 23 19 14 21 15 13 14 13
2: Should probably be allowed 21 21 27 24 13 16 26 22 20
3: Should probably not be allowed 21 17 20 18 28 24 18 24 23
4: Should definitely not be allowed 37 39 34 44 37 45 43 40 44

A modest difference.

Next, highest educational attainment:

No HS HS Some college College Graduate
1: Should definitely be allowed 7 14 11 26 32
2: Should probably be allowed 14 20 23 29 27
3: Should probably not be allowed 20 23 21 19 20
4: Should definitely not be allowed 59 43 45 26 21

The big gap here is between those with college and those without college educations.

Finally, we look at WORDSUM, which is a proxy for intelligence. It’s a ten word vocabulary test. Below in the columns are the number of answers a respondent got correct:

<5 5 6 7 8 9 10
1: Should definitely be allowed 8 10 12 16 24 30 36
2: Should probably be allowed 13 22 18 24 26 34 33
3: Should probably not be allowed 27 20 23 22 21 18 18
4: Should definitely not be allowed 52 48 47 38 29 18 12

I combined those who scored below 5 out of 10 (0-4) into one class. You can see that as score on this vocabulary test goes up, the view that racists should be allowed to meet in public goes up. It’s almost monotonic. The smartest people are more tolerant than the next smartest people who are more tolerant than the next smartest people, with the dumb being the least tolerant.

I made the below chart to illustrate this:

Often when it comes to views associated with “smart” people when you put it into some regression eduction accounts for all of the difference. In other words, the less intelligent educated have the same views as the intelligent educated, and the more intelligent but less educated have the same views as the less intelligent less educated. There are more older people who are intelligent but not educated, so it could be generational too (though in this case age does not seem to matter). A plausible hypothesis is that in many cases it is social milieu. Even if you are not bright, being in college inculcates certain values.

And college is a predictor. But these data show that even if you account for college education the brighter you are, the more likely you favor allowing tolerance for views that most people find intolerable.

Conservatives respect atheists less

Filed under: data,GSS — David Hume @ 2:18 am

This clip by S. E. Cupp is making the rounds. I often find Cupp to be glib, so it’s no surprise that I disagree with many of the details of what she is saying. In particular it struck me as strange to listen to her talk about how conservatives respect atheists. Atheists are held in low esteem by the American public as a whole, let alone by conservatives. The general social survey has a question, SPKATH, which states:

There are always some people whose ideas are considered bad or dangerous by other people. For instance, somebody who is against churches and religion… a. If such a person wanted to make a speech in your (city/town/community) against churches and religion, should he be allowed to speak, or not?

Here are fractions who would allow this person to speak or not not in 1972-1990:

charts

Here are fractions who would allow this person to speak or not not in 2000-2012:

charts2

Liberals tend to be more accepting of atheists making a speech than conservatives. Interestingly even in the 2000s ~20 percent of self-identified extreme liberals would still not allow an atheist speak. As opposed to ~40 percent of self-identified extreme conservatives.

Addendum: To be clear about the intent behind this post, I’m all about keeping it real. I think it is acceptable to be an atheist on the Right. A substantial proportion of libertarians are atheists. Even among non-libertarian conservatives it’s an acceptable position. But this is really mostly relevant at the elite levels pundits and policy professionals. Atheists just aren’t popular at the grass roots. There aren’t that many conservative atheists or atheist conservatives.

The general social survey: information is not free

Filed under: Data Analysis,GSS — Razib Khan @ 11:57 pm

Last week the GSS was down. I was very sad. The SDA team explains the situation:

Part of the popularity of our demonstration archive is that it is free for end users. We are happy to provide this service. It is a valuable resource for the academic community and it also publicizes the value of our SDA software. However, the flip side of providing this free service is that it does not generate any income to offset the cost of providing the infrastructure required. We receive no funding from GSS for hosting their datasets — which is often a surprise to our users. Almost all of our income comes from the fees provided by licensing the SDA software to other data archives (like ICPSR and IPUMS), and virtually all of that income goes to support the programming and technical support that we provide them. We obviously need some additional sources of revenue.

Political moderates and independents are not as smart on average

Filed under: GSS — Razib Khan @ 10:54 pm

Long time readers know that it’s trivially easy to extract information from the GSS that political moderates and independents are not as intelligent as partisans and ideologues. New readers are not always familiar. A comment:

#8 Do you have something to back up the idea that independents are less intelligent? If anything, I would’ve expected the opposite- that independents are capable of thinking for themselves instead of following the party line.

First, a quick review of the data. I used two GSS variables, PARTYID and POLVIEWS, and limited the sample to non-Hispanic whites after the year 2000. I removed those of “Other party” as well. Finally, I crossed that against vocab score results, which correlates with intelligence with a value of 0.70. It is rather obvious that middle-of-the-roaders are not as bright:

WORDSUM SCORE 0-2 3 4 5 6 7 8 9 10 Strong Dem 15 8 13 9 10 12 14 15 20 Dem 17 24 14 15 15 13 14 15 15 Lean Dem 11 9 8 11 11 11 10 18 14 Independent 26 23 23 21 18 16 14 11 11 Lean Repub 10 8 12 10 8 12 13 10 12 Repub 15 21 18 21 21 20 18 16 13 Strong Repub 6 8 11 13 18 16 16 16 15 Extreme Liberal 5 3 2 2 1 4 3 4 7 Liberal 5 11 6 6 8 12 10 16 20 Lean Liberal 6 10 13 7 10 11 12 17 14 Moderate 44 45 44 43 39 33 30 28 24 Lean Conservative 21 12 13 18 16 18 18 14 16 Conservative 14 16 16 20 22 17 22 19 15 Extreme Conservative 5 4 5 3 4 6 3 2 3

As you can see the proportion in the middle decreases as you go up in intelligence. Why? A straightforward explanation is that independents and moderates are “low information” political actors. And therefore they are likely to be less intelligent in the first place. But there is I think another ...

Intelligence challenged people and free speech

Filed under: Data Analysis,GSS,Speech — Razib Khan @ 5:23 pm

 

In the post below I took the time out to link to the GSS, as well as posting my exact queries. As payment for this consideration the first comment was absolute drivel. I understand people have political opinions, but I’m not too interested in your opinions. You may be interested in your opinions, but I’d rather have more data. Most people don’t know enough for me to have interest in their opinions (most != all, many readers do have opinions in their specialties which I seek out).

I was trying to make a point that anger and even violence in reaction to actions which offend are actually comprehensible as the modal human response. The community reacts to punish those who violate taboos. The taboos may differ, but the response to the action of violation is normal and natural. A primary issue that needs to be considered is that taboos differ from society to society, so one is often not conscious of the act of violation (e.g., if you show the bottom of your shoes to people when you sit down, that’s an offensive act in some societies).

An implication here is that American norms of free speech near absolutism, ...

Who tolerates anti-American preaching from Muslims?

Filed under: Anthroplogy,geography,GSS — Razib Khan @ 9:45 am

Obviously the news over the past week has been filled with the events in the Middle East, and the broader Muslim world, in reaction to an anti-Muslim film. I think the most eloquent commentary is from The Onion (NSFW!!!), No One Murdered Because Of This Image. That being said, there are some serious broader issues here. A friend of mine who lives in India (he is Indian American, though raised for several years in India, so not totally unfamiliar with the culture) has expressed to me his frustration with having to defend American liberalism in a society where American liberalism is an abstraction, rather than concrete. The frustration has to do with the fundamental divergence in basic values. For example, his interlocutors have argued to him (he is a practicing Christian of libertarian political orientation) that if someone committed an act of blasphemy against his faith of course he would react in anger and violence. And yet of course the clause “and” is false, though he is greeted with skepticism when he asserts he wouldn’t react violently. As a matter of fact I can attest to the reality that he wouldn’t react angrily necessarily, because in interactions where I’ve ...

Who rejects right to abortion in cases of rape?

Filed under: abortion,Data Analysis,GSS,Todd Akin — Razib Khan @ 10:56 pm

It’s basically impossible to avoid hearing about Todd Akin right now. My Twitter and Facebook feeds are kind of swamped. But it did make me wonder: what percentage of Americans reject abortion in cases of rape and incest? The GSS has a handy variable, ABRAPE, which asks respondents about the possibility of abortion if a woman gets pregnant as a result of rape (let’s stipulate that it’s possible to get pregnant as a result of rape!). I also limited the sample to the year 2000 and later, and non-Hispanic whites (to clear out confounds). Demographic breakdowns below….

Before people start complaining, the scale below goes from 0% to 50%, NOT 0% to 100%!

Opinions based on opinions may be fun, but opinions based on facts may be useful. In general my appeals have fallen on deaf ears.

More racist: white liberals or white conservatives?

Filed under: Data Analysis,GSS,Interracial,Racism — Razib Khan @ 10:02 pm

Reihan Salam has a post up on the alignment of racism and political orientation. He begins:

Recently, Chris Hayes, host of MSNBC’s UP with Chris Hayes, made the following observation:

It is undeniably the case that racist Americans are almost entirely in one political coalition and not the other.

Chris is a good friend of mine, and we grew up in the same milieu. I can attest to the fact that the view he expressed is very widely held in the circles in which we both travel….

Salam then links to Alex Tabarrok, who uses party identification data to indicate that actually racism is split between the two groups, while John Sides suggests that there is a definite lean toward Republicans being more racist, using a few indicator variables. Overall I think Sides is about right, all things equal conservatives are more racist than liberals. At least in the modern context of the two ideologies.* I say conservative/liberal rather than Republican/Democrat, because my experience with the GSS data set is that ideology is a more powerful predictor of social views among whites. This holds true with the variables which Tabarrok and Sides query from what I can see; the gap between ...

Higher vocabulary ~ higher income

Filed under: data,Data Analysis,GSS,Income,IQ — Razib Khan @ 7:54 pm

Prompted by a comment below I was curious as to the correlation between intelligence and income. To indicate intelligence I used the GSS’s WORDSUM variable, which has a ~0.70 correlation with IQ. For income, I used REALINC, which is indexed to 1986 values (so it is inflation adjusted) and aggregates the household income. Finally, I limited my sample to non-Hispanic whites over the age of 30 (for what it’s worth, this choice also limited the data set to respondents from the year 2000 and later).

The results don’t get at the commenter’s assertions, because 10 out of 10 on WORDSUM does not imply that you’re that smart really. But the trendline is suggestive. Note that aggregated 0-4 because the sample size at the lower values is small indeed.

Verbal intelligence by demographic

Filed under: Data Analysis,Demographics,GSS,Intelligence,WORDSUM — Razib Khan @ 7:43 pm

A few years ago I put up a post, WORDSUM & IQ & the correlation, as a “reference” post. Basically if anyone objected to using WORDSUM, a variable in the General Social Survey, then I would point to that post and observe that the correlation between WORDSUM and general intelligence is 0.71. That makes sense, since WORDSUM is a vocabulary test, and verbal fluency is well correlated with intelligence.

But I realized over the years I’ve posted many posts using the GSS and WORDSUM, but never explicitly laid out the distribution of WORDSUM scores, which range from 0 (0 out of 10) to 10 (10 out of 10). I’ve used categories like “stupid, interval 0-4,” but often only mentioned the percentiles in the comments after prompting from a reader. This post is to fix that problem forever, and will serve as a reference for the future.

First, please keep in mind that I limited the sample to the year 2000 and later. The N is ~7,000, but far lower for some of variables crossed. Therefore, I invite you to replicate my results. After the charts I will list all the variables, so if you care you should be able to ...

How income, class, religion, etc. relate to political party

Filed under: data,Data Analysis,Demographics,GSS,Politics — Razib Khan @ 9:11 pm

Update: There was a major coding error. I’ve rerun the analysis. No qualitative change.

As is often the case a 10 minute post using the General Social Survey is getting a lot of attention. Apparently circa 1997 web interfaces are so intimidating to people that extracting a little data goes a long way. Instead of talking and commenting I thought as an exercise I would go further, and also be precise about my methodology so that people could replicate it (hint: this is a chance for readers to follow up and figure something out on their own, instead of tossing out an opinion I don’t care about).

 

Just like below I limited the sample to non-Hispanic whites after the year 2000. Here’s how I did it: YEAR(2000-*), RACE(1), HISPANIC(1)

Next I want to compare income, with 1986 values as a base, with party identification. To increase sample sizes I combined all Democrats and Republicans into one class; the social science points to the reality that the vast majority of independents who “lean” in one direction are actually usually reliable voters for that party. So I feel no guilt about this. I suppose Americans simply like the conceit of being independent? I know I do. ...

Vocab by ethnicity, region, and education

Filed under: data,Data Analysis,GSS,I.Q.,Regionalism — Razib Khan @ 12:58 pm

A questioner below was curious if vocabulary test differences by ethnic and region persist across income. There’s a problem with this. First, the INCOME variable isn’t very fine-grained (there is a catchall $30,000 or greater category). Second, it doesn’t seem to control for inflation. But, there is a variable, DEGREE, which asks the highest level of education attained. I used this to create a “college” and “non-college” category (i.e., do you have a bachelor’s degree or not). Because of sample size considerations I removed some of the ethnic groups, but replicated the earlier analysis.

Below are two tables. One shows the mean vocab score for region and ethnicity (for whites) for those without college educations, and another shows those with college educations. I decided to generate a correlation over the two rows, even though it sure isn’t useful as a quantitative statistical measure because of the small number of data points. Rather, I just wanted a summary of the qualitative result. The short answer is that the average vocabulary difference seems to persist across educational levels (the exception here is the “German” ethnicity).

Vocabulary score by race, ethnicity, and region

Filed under: Data Analysis,Demographics,GSS,WORDSUM — Razib Khan @ 10:22 pm

Mike the Mad Biologist has a post up, A Modest Proposal: Alabama Whites Are Genetically Inferior to Massachusetts Whites (FOR REALZ!). The post is obviously tongue-in-cheek, but it’s actually an interesting question: what’s the difference between whites in various regions of the United States? I’ve looked at this before, but I thought I’d revisit it for new readers.

First, I use the General Social Survey. Second, I use the WORDSUM variable, a 10 question vocabulary test which has a correlation of 0.70 with general intelligence. My curiosity is about differences across white ethnic groups by region. To do this I use the ETHNIC variable, which asks respondents where their ancestors came from by nation. I omitted some nations because of small sample size, and amalgamated others.

Here are my amalgamations:

German = Austria, Germany, Switzerland

French = French Canada, France

Eastern Europe = Lithuania, Poland, Hungary, Yugoslavia, Russia, Czechaslovakia (many were asked before 1992), Romania

Scandinavian = Denmark, Norway, Sweden, Finland (yes, I know that Finland is not part of Scandinavia, Jaakkeli!)

British = England, Wales, Scotland

Next we need to break it down by region. The REGION variable uses the Census divisions. You can see them to the left. I combined a few of these to create the following classes:

Northeast = New England, Middle Atlantic

Midwest = E North Central, W North Central

South = W S Central, E S Central, South Atlantic

West = Pacific, Mountain

The key method I used is to look for mean vocabulary test scores by ethnicity and religion. I also later broke down some of these ethnic groups by religion. Finally, all bar plots have 95 percent confidence intervals. This should give you a sense of the sample sizes for each combination.

First let’s break it down by race/ethnicity and compare it by region to get a reference:


Next, the main course:

Finally, let’s separate by religion for Germans and Eastern Europeans:

I include the last plot because these reports of nationality have to be taken with a consideration for the structure they may mask. People whose ancestors from Poland in the United States fall into two large categories: people of Jewish heritage whose identity as ethnic Poles was contested (recall that Jews often spoke Yiddish as their first language, a Germanic language), and Roman Catholic Slavs. I suspect many of those in the “None” category are also Jews by culture, if not religion.

Second: there is a tendency of people of all ethnic groups to have lower vocabulary scores if they are from the South or Midwest. This tendency is in many cases outside of the 95 percent confidence interval. It’s especially striking in the three groups with huge samples sizes in all regions: Germans, Irish, and British. Irish here includes both Scots-Irish and those of Irish Catholic background. Not only are the sample sizes for these groups large, but the roots of these groups in some of these regions go rather far back. In particular, the division between the people of British ancestry goes back centuries in the North vs. South divide.

How to understand this? There are a lot of complicating factors.  But as outlined in Albion’s Seed and The Cousins’ Wars the divisions between the Anglo-Celtic folkways runs deep and long. If a time traveler from the 18th century arrived in the United States today and were asked which region was the heart of intellectual ferment they would correctly guess New England. Early Puritan New England was the first universal-literacy society in the world. This was to some extent a matter of conscious planning. The leaders of the New England colonies enforced limitations upon who could emigrate to their dominion. Religious exclusions and persecutions in this region are well known, but there was also a policy of rejecting the settlement of those who were perceived to be possible burdens upon the community. New England then selected for a middle class migration out of East Anglia and the port towns of southwest England. But the fathers of the early colony also rejected the transfer of the privileges of the blood nobility from the motherland, thereby throwing up a barrier to the migration of the aristocracy.

In contrast the lowland South received a more representative selection of the British class strata. The younger sons of the British nobility and self-styled gentlemen arrived to make their mark, as did those who became indentured servants and even slaves. A class society on the model of southwestern England recapitulated itself in this region. As for the uplands, what became Appalachia, an influx of Scots-Irish came to dominate the scene by the mid of the 18th century, disembarking in Philadelphia, and pushing down the spine of the high country down to the Deep South.

Conflicts between these “Anglo” groups framed the terms of debate over the 18th and 19th centuries. They were to some extent at the root of the Age of Sectionalism. Today because of the salience of race, and the prominence of the later wave of migration in the late 19th and early 20th century which remained vibrant in living memory for mod, these early divisions have moved out of sight. But they still remain. The difference between Germans in Texas and the Anglos of Southern extraction remains to this day, but note that Germans exhibit the same regional differences in vocabulary score as Anglos. Why? This may be a case where the original cultural substratum has an outsized impact (the dialect of eastern New England, made famous by the Catholic Irish of Boston, is descended from East Anglian English!).

Of course there might be a genetic difference. Intelligence is a quantitative trait, so it would be trivial to generate two populations which are genetically similar, but very different in trait value, simply through selection. In the 1630s ~20 thousands Puritans settled New England. For various reasons there was very little migration over the next century and a half. By 1780 New England’s population was 700,000, almost all through natural increase (not only was New England the world’s first universal literacy society, but its fertility was the highest in the late 17th century).

Finally, there’s the issue of disease and pathogen load. Endemic hookworm infection does seem likely to have made Southerners, of both races, relatively indolent and lethargic in comparison to Northerners. Who knows what pathogens simply fall below our radar?

Overall I think that a more fine-grained and detailed exploration of these topics is warranted. Our public discussion is too coarse, and data-thin.

Would you have your fetus genetically tested?

Filed under: Demographics,Genetic Testing,Genetics,GSS,Personal genomics — Razib Khan @ 12:22 pm

There’s a variable in the GSS, GENESELF, which asks:

Today, tests are being developed that make it possible to detect serious genetic defects before a baby is born. But so far, it is impossible either to treat or to correct most of them. If (you/your partner) were pregnant, would you want (her) to have a test to find out if the baby has any serious genetic defects?

This is relevant today especially. First, the technology is getting better and better. Second, couples are waiting longer to start families. Unfortunately this question was only asked in 1990, 1996, and 2004. But on the positive side the sample sizes were large.

I decided to combine 1990 and 1996 into one class. Also, I combined those who were very liberal with liberals, and did the same for conservatives. For political party ideology I lumped strong to weak identifiers. For intelligence I used WORDSUM. 0-4 were “dull,” 5-7 “average,” and 8-10 “smart.” For some variables there weren’t results for the 1990s.

The biggest surprise for me is that there wasn’t much difference between the 1990s and 2004. The second biggest surprise was that the differences between demographics were somewhat smaller than I’d expected, and often nonexistent. Below is a barplot and table with the results.
