Louis Proyect vs. Steven Pinker

Louis Proyect is the master of ad hominem argument. In a post pretentiously titled Pecksniff and the Harper’s Open Letter, he'd refuse to sign the Harper's Open Letter because he wouldn't want to join the disreputable crowd of hypocritical, prominent signatories. He never claims to oppose the letter's actual content, which champions free speech, open inquiry, and some minimal respect for persons who disagree. These are bourgeois values which I believe Mr. Proyect holds in low esteem--he is, after all, a totalitarian Marxist.

Certainly respect for persons who disagree is low on Mr. Proyect's list. This is what he says about Mark Lilla.
Mark Lilla—Another Columbia professor. His claim to fame is writing a book urging the Democrats to dump “identity politics”. Katherine Franke, a Columbia law professor compared Lilla to David Duke and charged him with “underwriting the whitening of American nationalism, and the re-centering of white lives as the lives that matter most in the U.S.” Maybe he signed the letter because she “canceled” him.
So apparently any skepticism about "identity politics" is the same as David Duke, who, we may extrapolate further, is just one short step away from H*tl*r. And that's the problem--anybody who disagrees with Mr. Proyect is ultimately associated with the H-man. This is supposed to pass for discourse.

He saves his worst bile for Steven Pinker.
Steven Pinker—Pinker is arguably the worst person who signed the letter. My interest in him was focused on his reactionary sociobiological theories that I described as a mixture of Hobbes and Pangloss. I also recommend a new Jacobin article titled “It’s Official — Steven Pinker Is Full of Shit”. I guess Jacobin was guilty of cancel culture.
I've read both Mr Proyect's post (entitled Steven Pinker = Hobbes + Pangloss, posted in 2011, which in turn links to a post from 2009) and the Jacobin piece. It appears that Mr. Proyect has never actually read any of Pinker's books, so on this I have an edge. I read The Blank Slate shortly after it was published in 2003. I have never read The Better Angels of our Nature--the book that really gets Mr. Proyect's goat.

Sociobiology (aka evolutionary psychology) asserts two premises--the veracity of which are to be proven empirically.

1) That human evolution occurs much more rapidly than was believed in the 20th century.
2) That genetic evolution happens not just in response to changes in the natural environment, but also to changes in the social environment. This leads to the concept of gene-culture co-evolution. (For more about this, see Joseph Henrich.)

The first premise is now demonstrated beyond any reasonable doubt. Detectable evolution can happen in historical time--certainly within a few thousand years, and likely within one thousand years. Indeed, it can happen almost immediately, as when a small band of people separates from a much larger group, and by crossing a mountain range loses genetic contact with their ancestors. They will be genetically distinct almost from the git-go--even if they represented a random sample before they crossed the mountain range.

Analysis of the human genome (first sequenced in 2003) has become cheap and ubiquitous. Coupled with massive data processing power, it is now possible for commercial companies (e.g., 23&me) to distinguish ethnic groups by genomic analysis alone.

The second premise is harder to definitively establish, but it can be said with confidence that genes correlate with personality traits, which collectively contribute to culture. Correlation obviously does not prove causation, and because genetic influences are extremely complicated and subtle, proving causation will be difficult to impossible except in a few cases (e.g., lactose tolerance). But correlation certainly suggests causation, and in many cases it probably results from causation.

In the 2009 post Mr. Proyect attributes the following statements to Pinker.
  • Males have a stronger tolerance for physical risk and a stronger drive for anonymous sex. 
  • Women have stronger emotions and are better at reading emotions on the faces of others. 
  • Pinker states “A variety of sexual motives, including taste in men, vary with the menstrual cycle.” 
  • He also states that “in a sample of mathematically talented students, boys outnumbered girls by 13 to one” but that women maintain more eye-contact, and smile and laugh more often. 
  • Humans are hard-wired to think in stereotypes and to prefer kin. 
  • Some people, most of them men, are born with criminal tendencies. 
  • Turning to the big questions of social transformation that have vexed Great Thinkers for the millennium, we learn from Pinker that “Biological facts are beginning to box in plausible political philosophies.” Communism may work for insects, but humans are programmed for economic exchange and “reciprocal altruism.” (Is that the reason I used to climb across the ceilings and consume a pound of sugar at a time when I was in the Trotskyist movement, I wonder?)
Apart from the last bullet, there is abundant empirical evidence--genetic, neurological, anatomical, behavioral, and anthropological--to support all these claims. The best, recent source for this is Charles Murray's 2019 book entitled Human Diversity (my review here). The author compiles huge datasets (sample sizes in the millions) to support the assertions listed above (and much more besides).

I know, I know. I genuinely wish that somebody else besides Mr. Murray had written the book, and failing that I wish he'd written it under a pseudonym. But it is really important here to separate the subject from the author. Mr. Murray has written a textbook instead of a monograph. He has not done the research himself, but has put together the data from the scientific literature compiled by other people. One common criticism of Mr. Murray's book is that he's published no peer reviewed papers. I don't know if that's true, but it's irrelevant--textbook authors are not typically researchers themselves.

The other common criticism is that he's "cherry-picked" the data. This is both cheap and irrefutable. Any author--even a textbook author--has to pick and choose what to include and what to leave out. So of course the contents are "cherry-picked" in that trivial sense. The implication, however, is that he's hiding some crucial bit of data that disproves his thesis--presumably because he's dishonest, racist, and his name is Charles Murray. I find this incredible. While the book can certainly be criticized, it won't be easily dismissed because of some magic, missing data point.

The Blank Slate, published in 2003, did not have access to the voluminous data at Murray's fingertips. It is necessarily more speculative, and has been criticized for telling just so stories. But Murray's subsequent data have largely confirmed Pinker's hypotheses.

In the 2009 post Mr. Proyect writes about Pinker:
For all of Pinker’s animosity to radicalism and Marxism in particular, there is very little evidence that he understands how historical materialism deals with the question of human nature. While it is beyond the scope of this article to trace its development through the years, suffice it to say that Marxism views the nature-nurture relationship dialectically.
It does not really challenge the existence of biologically determined traits, but simply places the whole question of equality, justice and freedom in a materialist context. In other words, revolutionary socialism strives to create the conditions in which all human beings can reach their full potential. Within the context of such a challenge, Pinker’s “Blank Slate,” with its discussions about the difference between the appearance of male and female brains (according to Pinker, they are “nearly as distinct as their bodies”) seems little more than “Men Are From Mars, Women Are From Venus” geared to readers of the New York Review of Books.
It turns out that the pop-culture Mars/Venus stories are not that far off the mark. Most people understand that men and women are different in the ways one expects. (Only woke people on college campuses have forgotten how to do that.) But Murray's data is much more rigorous: first, it's actual data with sample sizes in the millions rather than mere anecdotes; second, it can quantify the differences, and also the similarities between men and women; and finally, it can at very least correlate those differences with differences with genomic and neurological data. In some cases it can establish causation.

Opponents of sociobiology will not get very far by firing shots at Charles Murray. First, he's just the messenger, and second, his book is very thorough. What they need to do instead is write a competing textbook. If Marxist dialectics are indeed the key to the nature-nurture debate, then by all means write the textbook that makes that case. But it must take the data seriously--you can't just philosophize in the abstract about "equality, justice and freedom," along with empty words like "dialectically," and expect to get away with it.

Materialism, if it means anything at all, certainly means arguing from empirical data.

One last point: nobody is arguing for genetic determinism. The environment plays a large role--both for individual outcomes, and certainly for cultural outcomes. I hope there's even room for old curmudgeons like me who still believe free will has at least a small remit.

But what is now undeniably true is that genes play a significant role in explaining variation between individuals, and also between ethnic groups. While genetic determinism is wrong, it is equally impossible to ignore genetics when thinking about human health, psychology, and culture.

Mr. Murray makes that point. He argues that, within the next ten years, academic papers in the social sciences will all include genetic data as a matter of course, and will be unpublishable otherwise. This is already true in biology, medicine, and psychology, and will spread to sociology and economics--even in the face of political correctness.

So the window of opportunity for our Marxist friends to write their textbook is closing fast. Mr. Proyect needs to get busy.
