Unexpected consequences of the Orthodox growth: Unz points out an apparent massive fall in Jewish academic achievement:
For example, consider California, second only to New York in the total number of its Jews, and with its Jewish percentage far above the national average. Over the last couple of years, blogger Steve Sailer and some of his commenters have examined the complete 2010 and 2012 NMS semifinalist lists of the 2000 or so top-scoring California high school seniors for ethnicity, and discovered that as few as 4–5 percent of the names seem to be Jewish, a figure not so dramatically different than the state’s 3.3 percent Jewish population, and an estimate which I have personally confirmed.54 Meanwhile, the state’s 13 percent Asians account for over 57 percent of the top performing students. Thus, it appears that California Asians are perhaps three times as likely as Jews to do extremely well on academic tests, and this result remains unchanged if we adjust for the age distributions of the two populations...When we consider the apparent number of Jewish students across the NMS semifinalist lists of other major states, we get roughly similar results. New York has always been the center of the American Jewish community, and at 8.4 percent is half again as heavily Jewish as any other state, while probably containing a large fraction of America’s Jewish financial and intellectual elite. Just as we might expect, the 2011 roster of New York NMS semifinalists is disproportionately filled with Jewish names, constituting about 21 percent of the total, a ratio twice as high as for any other state whose figures are available. But even here, New York’s smaller and much less affluent Asian population is far better represented, providing around 34 percent of the top scoring students. Jews and Asians are today about equal in number within New York City but whereas a generation ago, elite local public schools such as Stuyvesant were very heavily Jewish, today Jews are outnumbered at least several times over by Asians.55...Earlier we had noted that the tests used to select NMS semifinalists actually tilted substantially against Asian students by double-weighting verbal skills and excluding visuospatial ability, but in the case of Jews this same testing-bias has exactly the opposite impact. Jewish ability tends to be exceptionally strong in its verbal component and mediocre at best in the visuospatial,57 so the NMS semifinalist selection methodology would seem ideally designed to absolutely maximize the number of high-scoring Jews compared to other whites or (especially) East Asians. Thus, the number of high-ability Jews we are finding should be regarded as an extreme upper bound to a more neutrally-derived total...But today, MIT’s enrollment is just 9 percent Jewish, a figure lower than that anywhere in the Ivy League, while Asians are nearly three times as numerous, despite the school being located in one of the most heavily Jewish parts of the country...The U.S. Math Olympiad began in 1974, and all the names of the top scoring students are easily available on the Internet. During the 1970s, well over 40 percent of the total were Jewish, and during the 1980s and 1990s, the fraction averaged about one-third. However, during the thirteen years since 2000, just two names out of 78 or 2.5 percent appear to be Jewish. The Putnam Exam is the most difficult and prestigious mathematics competition for American college students, with five or six Putnam winners having been selected each year since 1938. Over 40 percent of the Putnam winners prior to 1950 were Jewish, and during every decade from the 1950s through the 1990s, between 22 percent and 31 percent of the winners seem to have come from that same ethnic background. But since 2000, the percentage has dropped to under 10 percent, without a single likely Jewish name in the last seven years. This consistent picture of stark ethnic decline recurs when we examine the statistics for the Science Talent Search, which has been selecting 40 students as national finalists for America’s most prestigious high school science award since 1942, thus providing a huge statistical dataset of over 2800 top science students. During every decade from the 1950s through the 1980s, Jewish students were consistently 22–23 percent of the recipients, with the percentage then declining to 17 percent in the 1990s, 15 percent in the 2000s, and just 7 percent since 2010. Indeed, of the thirty top ranked students over the last three years, only a single one seems likely to have been Jewish. Similarly, Jews were over one-quarter of the top students in the Physics Olympiad from 1986 to 1997, but have fallen to just 5 percent over the last decade, a result which must surely send Richard Feynman spinning in his grave. Other science competitions provide generally consistent recent results, though without the long track record allowing useful historical comparisons. Over the last dozen years, just 8 percent of the top students in the Biology Olympiad have been Jewish, with none in the last three years. Between 1992 and 2012, only 11 percent of the winners of the Computing Olympiad had Jewish names, as did just 8 percent of the Siemens AP Award winners. And although I have only managed to locate the last two years of Chemistry Olympiad winners, these lists of 40 top students contained not a single probable Jewish name. Further evidence is supplied by Weyl, who estimated that over 8 percent of the 1987 NMS semifinalists were Jewish,60 a figure 35 percent higher than found in today’s results.
Why?
Finally, in the case of Jews, these assimilation- or environment-related declines in relative academic performance may have been reinforced by powerful demographic trends. For the last generation or two, typical Jewish women from successful or even ordinary families have married very late and averaged little more than a single child, while the small fraction of Jewish women who are ultra-Orthodox often marry in their teens and then produce seven or eight children.69 As a consequence, this extremely religious subpopulation has been doubling in size every twenty years, and now easily exceeds 10 percent of the total, including a far higher percentage of younger Jews. But ultra-Orthodox Jews have generally been academically mediocre, often with enormously high rates of poverty and government dependency.70 Therefore, the combination of these two radically different trends of Jewish reproduction has acted to stabilize the total number of Jewish youngsters, while probably producing a sharp drop in their average academic achievement.
