This is a straw man, no? It’s a far stronger argument – to the point of being absurd – than Murray ever makes. I believe that in The Bell Curve’s own words the authors were “agnostic” on the subject of genes v. environment, leaning to both having a role (full disclosure: like everyone else, I have not read the book).
That’s is their great sin, right? The correlation between IQ and positive outcomes (education, wealth, etc.) is a fact. The existence of “g,” the general intelligence IQ tests purport to measure, is widely accepted in the relevant scientific community. Observed gaps in IQ scores between somewhat arbitrary but socially significant groupings of people with varying degrees of shared ancestry and correlated genes (i.e., “races”) are likewise a fact. Intelligence being largely heritable is a fact.
The Bell Curve survives at least this far in any honest assessment, I think. But its authors take the additional step of attempting to assess how genetics v. environment plays a role in the observed racial gaps in America, and come to a relatively measured conclusion: “we aren’t sure, but a bit of both probably contribute.”
For this Murray, who had the misfortune to survive until the book’s publication, has become a pariah, an embodiment of “pseudoscientific racism.” Is this really fair? As Salvor argues at length above, there are at least a priori reasons to think that groups of people segregated by culture and geography might develop somewhat different genes, on average. The mental consequences of those differences could be unmeasurably small, but the idea is not a ridiculous one.
It’s not like Murray denies the role of environment. In this very podcast, and I believe in the book as well, Murray uses the analogy of corn planted in Iowa vs. corn planted in the desert (white Americans’ environment is Iowa; black Americans’ is the desert). Later, he describes meeting black students at Harvard as an undergraduate, and assuming that they’re innately smarter than he is, given his environmental advantages (I assume this predated affirmative action, which he does not care for). These do not strike me as the musings of a raving racist.
I’m sufficiently uncomfortable with this topic and sufficiently uneducated in the relevant fields that I’m resistant to the conclusion that racial IQ differences are significantly genetic in origin - but I honestly don’t know the right answer. Are East Asians better at spacial reasoning than Caucasians, on average, due to different allele frequencies rather than cultural or environmental factors? That’s a question for science to answer, if it cares to. I don’t see how the answer can be an obvious “No, you #%#% racist.”
By the way, I just made an account on these forums, as I just listened to this podcast, thought Murray seemed somewhat mistreated, and was curious as to the response. I, uh, promise that I’m not an enthusiastic racist running to a new environment to spew my bile.
