Your responses raises two thoughts with me.
The first is that I've more recently seen arguments made that social silos in the US are becoming culturally significant which seems to run parallel to an argument being made in your book but believed to be multi-variable and self-enforcing with little to do with innate genetics as much as social point of origin. This increasing siloing is aided by technology as people increasing date among their social-economic peers which decreases a historic means of upward social mobility where geography may have made more cross-boundary relationships possible. It's exacerbated by the unaffordability of housing within enclaves of the high-earning members of society such that there is increasing less direct cross-culture exchange in the US along with upward mobility barriers increasingly being tied to the circumstances of birth dependent on whether one is fortunate enough to be born into a family in such an enclave with access to all this brings, or is unfortunate and born outside of such an enclave with all the disadvantages this brings.
It sounds like Murray and co., would say that smart people date other smart people, have smarter children which causes the population to drift into two genetic poles which can also be mapped onto one's ethnic background. Given the more recent arguments focus on how the socio-economic background one is born into exerts strong influence on the socio-economic status one obtains in life, this argument from genetics seems out of touch with the times while making an argument that would demand a rather difficult rigorous attempt to isolate genetics out of the socio-economic background to be able to make such a claim. And I didn't see your summary demonstrate this was done.
On your first point above, yes. In fact, a few years ago Murray has talked about
super zip codes--areas where people grow up in relative isolation where almost everybody is above-average in almost every way.
In fact, his latest book is called
Coming Apart: The State of White America, 1960-2010 which discusses this trend as being an entirely new thing. I laugh at the idea of neo-nazis purchasing the book thinking from the title that the book is racist. The joke is on them though:
In Coming Apart, Charles Murray explores the formation of American classes that are different in kind from anything we have ever known, focusing on whites as a way of driving home the fact that the trends he describes do not break along lines of race or ethnicity.
Drawing on five decades of statistics and research, Coming Apart demonstrates that a new upper class and a new lower class have diverged so far in core behaviors and values that they barely recognize their underlying American kinship—divergence that has nothing to do with income inequality and that has grown during good economic times and bad.
The top and bottom of white America increasingly live in different cultures, Murray argues, with the powerful upper class living in enclaves surrounded by their own kind, ignorant about life in mainstream America, and the lower class suffering from erosions of family and community life that strike at the heart of the pursuit of happiness. That divergence puts the success of the American project at risk. [Of course I'm sure that while the book
says it's explicit purpose is that these trends "do not break along lines of race or ethnicity", that EA will claim that the
real point of the book is about how Murray hates blacks.]
On your second point, Murray does talk about this a lot and does his best to control for it. For example, he cites studies where twins were separated at birth and put up for adoption in dramatically different environments. For example, say one twin is put into a "bad" home in a bad neighborhood and has nothing going for him, and his IQ is 85. Say his twin is put into an excellent home in an excellent neighborhood with excellent schools, where the average IQ of his adapted siblings and classmates are 110. The twin in the good home will end up with a higher IQ than the twin in the bad home, but will still be below average. Say, with an IQ of 95.

He's got strengths and weaknesses as a thinker which I tend to take into account when engaging his content. In this case, it wouldn't surprise me at all to see Harris leaning into an argument that is crossing his pet-peeve with college campus intolerance and a certain libertarian belief in socio-economic status demonstrating truths about market conditions that justify branding the losers in the market as somehow deserving.
Possibly. I am honestly bewildered at why Harris thought posting that email conversation with the editor of Vox would be a good thing.
honorentheos wrote:The second thought is related to IQ as a metric generally which I've understood requires one acknowledge that what it measures isn't so much innate intelligence in some sort of objective form, but rather the ability to perform mental tasks defined by mathematic, linguistics (in the US this by default means one's proficiency with English of a certain formal type and usage) and spatial-visualization proficiencies that are looked on favorably in post-industrial western cultures. The analogy used maybe over-simplified but essentially like this cartoon below, one ought to consider this when looking at results -

The book talks a lot about this as well. Some psychologists--most notably Howard Gardner, would totally agree with your point. Murray subscribes to the competing view that something called "general intelligence" exists. Quoting from the introduction of the book:
[Charles] Spearman [a psychologist who studied this stuff a century ago] noted that as the data from many different mental tests were accumulating, a curious result kept turning up: If the same group of people took two different mental tests, anyone who did well (or poorly) on one test tended to do similarly well (or poorly) on the other. This outcome did not seem to depend on the specific content of the tests. As long as the tests involved cognitive skills of one sort or another, the positive correlations appeared....Eventually, he hypnotized that there is something he calls
g which represents "general intelligence", which is a measure of a person's capacity for complex mental work. Apparently, they've researched this a lot over the last 100+ years, and the idea still has traction with psychologists. IQ tests are now considered the best measure of "g", but as noted above, any cognitive test is going to be at least correlated with "g". As corroborated by EA's critical source, even if you don't believe "g" exists, there is robust evidence that IQ test scores are in fact highly predictive of many important socioeconomic outcomes.
Of course while IQ is predictive in a statistical sense, there is also a ton of epsilon--individual differences from the mean predicted by the model. Perhaps Gardner's more subtle views on intelligence can explain why some people with relatively low (high) IQ's do relatively well (poorly).
