In a series of recent posts I and several others have strongly criticized Nicholas Wade’s recent book “A Troublesome History”, which purports to show that human races are biologically meaningful categories, characterized by different behavioral tendencies (which have resulted in different degrees of socio-political success). Now 139 professors with expertise in genetics, human biology, biological anthropology, and evolution have added their voices to this discussion, criticizing Wade’s book in a strongly worded letter that appears in the New York Times today. The full text of their letter can be found here. Organized by Grahm Coop, Michael Eisen, Rasmus Nielsen, Molly Przeworski, and Noah Rosenberg, the signatories include many of the leading researchers in human genomics (a full list of signatories and their affiliations can be found here).
Several of the authors are people whose research Mr. Wade cited approvingly in his book as supporting his thesis, such as Dr. Sarah Tishkoff, Dr. David Reich, and Dr. Noah Rosenberg (lead author of the 2002 paper that Mr. Wade uses as the primary evidence for his conception of genetically distinct races).
According to Michael Balter in an article appearing today in Science:
The letter was spearheaded by five population geneticists who had informally discussed the book at conferences, says co-organizer Rasmus Nielsen of the University of California, Berkeley. “There was a feeling that our research had been hijacked by Wade to promote his ideological agenda,” Nielsen says. “The outrage … was palpable.”
The authors don’t mince words:
Wade juxtaposes an incomplete and inaccurate account of our research on human genetic differences with speculation that recent natural selection has led to worldwide differences in I.Q. test results, political institutions and economic development. We reject Wade’s implication that our findings substantiate his guesswork. They do not.
We are in full agreement that there is no support from the field of population genetics for Wade’s conjectures.
This letter is highly inconvenient for Mr. Wade, making it clear that the senior researchers in the fields from which he’s trying to marshal support categorically reject his storytelling and bad science. Nor can he continue to make the (untrue) argument that critiques of his book are largely politically based, and conducted mainly by social scientists. A strong blow has been dealt to scientific racism today.

UPDATE: Mr. Wade has issued a statement responding to the letter. He starts out reasserting the position I claimed above that he can’t continue to hold:
“This letter is driven by politics, not science. I am confident that most of the signatories have not read my book and are responding to a slanted summary devised by the organizers.
As no reader of the letter could possibly guess, “A Troublesome Inheritance” argues that opposition to racism should be based on principle, not on the anti-evolutionary myth that there is no biological basis to race. Unfortunately many social scientists have long denied that there is a biological basis to race. This creed, prominent throughout the academic world, increasingly impedes research. Biologists risk damaging their careers if they write explicitly about race.
In yesterday’s post on the subject, Mr. David Dobbs described who several of the authors are:
Those signers include
Noah Rosenberg, the lead author of a 2002 paper that Wade leans on especially heavily, ”Genetic Structure of Human Populations,“ as well as at least two other authors of the paper.
Yale’s Kenneth Kidd, who is one of the world’s most respected population geneticists, a central figure in establishing the field, and another co-author on the 2002 Rosenberg paper.
Stanford’s Jonathan Pritchard, another co-author on that paper and the researcher whose lab designed the ”Structure“ genetic analysis software that created the ”clustering“ data Wade says supports his argument.
Sarah Tishkoff, lead author of a 2009 paper on ”The Genetic Structure and History of Africans and African-Americans“ that Wade cited extensively as crucial support.
Jun Li and Richard Myers, the lead and senior authors of a 2008 paper, ”Worldwide Human Relationships Inferred from Genome-Wide Patterns of Variation,” that, as I noted in my review, Wade misrepresented as supporting his argument.
These and the other signatories of the letter are the leaders in the field of human population genetics. They do not shy away from research and writing about human genetic variation. Mr. Wade is wrong to imply that they are being intimidated by cultural anthropologists. The fact that they agree on a single statement (on anything) is extraordinary and should be treated seriously.
Further, I suspect that more people on that list have read his book than he believes, simply because I’ve talked to them. In fact, Jerry Coyne, one of the signers of the letter has read it twice. (I encourage you to read his thoughts on the subject at the link above).
Disturbingly, Mr. Wade appears to be adopting the methodology of his “HBD” followers in claiming that evolution requires acceptance of his view of race. The data do not support that position, and saying so doesn’t make any of us anti-evolution, no matter how loudly he says it.
He goes on:
These attacks have included repeated assertions that the book is scientifically inaccurate, a charge for which I have seen no basis. In the same vein, this letter issues general charges without supporting evidence.
True, the letter doesn’t go into a detailed scientific refutation of his book. But there’s hardly space in the letter section of the NY Times to document his numerous errors, and many of us have done that already (For example “The troublesome ignorance of Nicholas Wade” by Agustin Fuentes, “How A Troublesome Inheritance gets human genetics wrong” by Jeremy Yoder, “The genes made us do it: The new pseudoscience of race” by Jon Marks, “A guide to the science and pseudoscience of ‘A Troublesome Inheritance’” by Chris Smith, “A Troubling Tome” by Greg Laden, “On the origin of white power” by Eric Michael Johnson, and “The fault in our DNA” by David Dobbs). If you take a look at the various reviews of his book, you’ll see that they tend to cover many of the same points. Mr. Wade has consistently ignored all of them. His only responses to critics (myself, Agustin Fuentes, Jon Marks, and later Pete Shanks), has been to dismiss our credentials without seriously engaging with the substance of our points, calling us “incoherent with rage”. He’s ignored many other detailed critiques. Given all of this, I’m fairly certain that there are no terms in which 139 professors could couch a critique that would satisfy Mr. Wade. Who is actually being political here?
You might find this American Anthropological Association-sponsored debate between Agustin Fuentes and Nicholas Wade illuminating:
ETA (8/10/14): I mistakenly listed only Dr. Coop as the organizer of the letter. I’ve edited to add the names of the other professors who organized and wrote it. My sincere apologies for the oversight.
