Peter Frost`s Explanation For High Average Ashkenazi Jewish IQs–And Why Anthropologists Aren`t Cool Anymore
Attempts to come up with a Darwinian explanation for the high average IQ of European Jews go back at least to Norbert Weiner`s 1953 autobiography, in which he argued that arranged marriages between the shetl`s brightest young rabbi and the richest merchant`s daughter would lead to large numbers of smart children having enough money to survive. In 2005, Greg Cochran, Henry Harpending, and Jason Hardy put forward a sophisticated theory pointing to selection for the mental demands of traditional Ashkenazi occupations such as moneylender. In Commentary, Charles Murray recently suggested the Babylonian Captivity could have played a role.
For a number of years, anthropologist Peter Frost has been privately advocating a fourth theory. Frost is the author of the 2005 book Fair Women, Dark Men: The Forgotten Roots of Color Prejudice, which I reviewed in VDARE.com. On Wednesday, Frost posted in the comments to Mahalanobis` item on economist Greg Clark`s new book showing that the prosperous had many more surviving children than the poor in medieval and early modern England. The comment summarizes Frost`s theory of the evolution of Ashkenazi intelligence:
The same process was going on in other European nations, but to varying extents. I commented on this point in the following letter to Commentary (which was never published):
In “Jewish Genius” [April] Charles Murray states that selection for intelligence has historically been stronger in some occupations than in others, being notably stronger in sales, finance, and trade than in farming. Insofar as he is right, the reason lies not in the occupation itself but in its relations of production.
In the Middle Ages and earlier, farmers had little scope for economic achievementâ€”and just as little for the intelligence that contributes to achievement. Most farmers were peasants who produced enough for themselves, plus a surplus for the landowner. A peasant could produce a larger surplus, but what then? Sell it on the local market? The possibilities there were slim because most people grew their own food. Sell it on several markets both near and far? That would mean dealing with a lot of surly highwaymen. And what would stop the landowner from seizing the entire surplus? After all, it was his land and his peasant.
The situation changes with farmers who own their land and sell their produce over a wide geographical area. Consider the “Yankee” farmers who spread westward out of New England in the 18th and 19th centuries. They contributed very disproportionately to American inventiveness, literature, education, and philanthropy. Although they lived primarily from farming, they did not at all have the characteristics we associate with the word “peasant.”
Conversely, trade and finance have not always been synonymous with high achievement. In the Middle Ages, the slow growth economy allowed little room for expanding a business within one`s immediate locality, and expansion further afield was hindered by brigandage and bad roads. Furthermore, the static economic environment created few novel situations that required true intelligence. How strong is selection for intelligence among people who deal with the same clients, perform the same transactions, and charge the same prices year in and year out?
This point has a bearing on the reported IQ differences between Ashkenazi and Sephardi Jews. Charles Murray, like others, believes that the Ashkenazim were more strongly selected for intelligence because they were more concentrated than the Sephardim in sales, finance, and trade, especially during the Middle Ages. Now, we have no good data on the occupations of medieval Ashkenazim and Sephardim. But the earliest censuses (18th century for Polish Jews and 19th century for Algerian Jews) show little difference, with the bulk of both groups working in crafts.
There was, however, one major demographic difference. While the Sephardim grew slowly in numbers up to the 20th century, the Ashkenazim increased from about 500,000 in 1650 to 10 million in 1900. The same period saw strong population growth among Europeans in general. This boom used to be attributed to falling death rates alone, but demographers now recognize that rising birth rates were also responsible, in some countries more so. In England, the rise in fertility contributed two and a half times as much to the increase in growth rates as did the fall in mortality, largely through a decline in the age of first marriage.
This trend toward early marriage coincided with growing use of roads, canals and, later, railways to distribute goods over a much larger geographical area. The baby boom was particularly concentrated among semi-rural artisans who produced on contract for urban merchants and who could ably exploit these larger, more elastic markets. “They were not specialized craftsmen in life-trades with skills developed through long years of apprenticeship; they were semi-skilled family labour teams which set up in a line of business very quickly, adapting to shifts in market demand” (Seccombe 1992. A Millennium of Family Change. p. 182). Their workforce was their household. In more successful households, the workers would marry earlier and have as many children as possible. In less successful ones, they would postpone marriage, or never marry.
In Western Europe, these cottage industries were concentrated in areas like Ulster, Lancashire, Yorkshire, Brittany, Flanders, Alsace, Westphalia, Saxony, the Zurich uplands, the Piedmont, and Lombardy. In Eastern Europe, they were concentrated among Ashkenazi Jews. Selection for intelligence among the Ashkenazim may thus have been part of a larger European-wide selection for intelligence among cottage industry workers. These entrepreneurial artisans had optimal conditions for selection: 1) a tight linkage between success on an intelligence-demanding task and economic achievement; 2) considerable scope for economic achievement; 3) a tight linkage between economic achievement and reproductive success; and 4) considerable scope for reproductive success. Such artisans were a minority in Western Europe. Among the Ashkenazim, they appear to have been the majority.
In the late 19th century, cottage industries gave way to factories and the tight linkage between economic achievement and reproductive success came undone. Entrepreneurs could now expand production by hiring more workers. Henry Ford, for instance, produced millions of his famous Model T but had only one child.
In conclusion, Charles Murray errs in thinking that selection for intelligence is driven by the type of occupation. The relations of production seem to be more important, in particular whether the worker owns the means of production, whether there is scope for economic achievement, and whether increases in production are driven by increases in family size.
By the way, it`s quite sad how anthropologists have gone from glamour boys and girls in the 1950s to being almost ignored in the 2000s. Cultural anthropologist Margaret Mead, for example, was the Steve Levitt of the post-war era, an omniscient seer consulted on every topic imaginable. (For example, a fictionalized version of her named “Margaret Mader” has a sizable role as a space-traveling anthropologist in Robert A. Heinlein`s 1957 sci-fi classic Citizen of the Galaxy. She explains to the young hero the complex family structure of the Free Traders` spaceship.)
But the rival school of physical anthropologists led by the two-fisted Carleton Coon could also generate celebrities. Coon, for instance, was a regular panelist on a high-brow TV gameshow called “What in the World?” that ran from 1951-1964. On it, Coon and a couple of other anthropologists would be shown some random object from a museum collection and then try to guess whether it was a Neanderthal`s sternum or whatever.
Coon`s specialty was “The Wilder Whites:” Berbers, Albanians, and other tough mountain peoples who found the macho Coon to be their kind of man. During WWII, Coon served in the OSS and his chief assignment was to prepare to be “Lawrence of Morocco”–if Franco ever let Hitler`s armies have right of passage through Spain, they could land on the North African coast behind the Anglo-American forces fighting Rommel`s army in Libya and roll them up. If that happened, Coon would disappear into the Rif Mountains and rally the wild Berber tribes to fight a guerilla war against the German occupiers.
My guess is that what went wrong was that the Franz Boas / Margaret Mead school of cultural anthropology succeeded in demonizing their enemies like Coon. Without rivals anymore to keep them on their game, the cultural anthropologists got complacent and politically correct, and thus boring. The subject is still fascinating, but you`d only find that out these days from a handful of anthropologists, such as Frost, Harpending, Stanley Kurtz, and Peter Wood.
That`s too bad because anthropology ought to be the foundational social science, what physics is to the hard sciences.
