Ashkenazi were never more than 4% of the population, and if they took a disproportionate amount of the awards and top slots, everyone else still had slots without much scrambling. Ditto the Northeast Asians, though that gap is less. That's not so much the case with African-American, Native, and Hispanic populations.<br /><br />A lot of folks do have resentment against them. Perhaps I am less bothered simply because they were my friends in school and in the workplace. Intelligent secular Jews have had enormous cultural influence, and perhaps I should resent them as a group for that. But I don't. Many of those changes have been good, after all, and much of the negative was byproduct rather than aim.Assistant Village Idiothttps://www.blogger.com/profile/01978011985085795099noreply@blogger.comtag:blogger.com,1999:blog-19305198.post-37003923263035345062012-12-30T01:16:49.154-05:002012-12-30T01:16:49.154-05:00But I think it's a horror.
Just out of curios...<i>But I think it's a horror.</i><br /><br />Just out of curiosity, are you likewise horrified by the gap between average white IQ and average Ashkenazi IQ? (I make that comparison because if I remember correctly, it's around the same size as the US black average/white average gap.)<br /><br />I personally am more horrified by the latter than the former, but I think that's because of my suspicion that the black/white gap is largely due to environment - that is, that something is happening that robs many black Americans of part of their intelligence potential - while the white/Jewish gap I suspect is genetic.<br /><br />I have no real support for either suspicion, though.jaedhttps://www.blogger.com/profile/03328666344764784829noreply@blogger.comtag:blogger.com,1999:blog-19305198.post-4684008315735504812012-12-29T17:49:32.368-05:002012-12-29T17:49:32.368-05:00You can't raise the ceiling much in a few gene...You can't raise the ceiling much in a few generations, but you can raise the floor.

And because of the importance of perceptions in a population, the tails can matter quite a bit.<br /><br />Laura, another thought occurs to me that I would like to run by hbd chick and that group. The Irish, despite being Roman Catholic, were outside the Hajnal Line, and thus more prone to cousin marriage. That likely vanished upon arrival in the US, and raised the floor quickly. What we see as a conscious effort to abandon pathological behaviors may be driven in part by having fewer in the population who were simply unable to cope with urban complexity from birth.<br /><br />It certainily didn't hurt. First cousin marriage is a genetic disaster for intelligence, and even second-cousin marriage has a depressing effect.Assistant Village Idiothttps://www.blogger.com/profile/01978011985085795099noreply@blogger.comtag:blogger.com,1999:blog-19305198.post-14542302987085103992012-12-28T23:45:35.151-05:002012-12-28T23:45:35.151-05:00Even a little shift can change the relative propor...Even a little shift can change the relative proportions in the extreme tails by a lot.jameshttps://www.blogger.com/profile/01792036361407527304noreply@blogger.comtag:blogger.com,1999:blog-19305198.post-21188817156807860552012-12-28T22:00:13.855-05:002012-12-28T22:00:13.855-05:00Laura - largely true.

Not entirel7y, but enough to know tha the answer does not lie there. The same effects show up when SES is held constant, for example. Ron Unz has some of the best numbers for your POV, BTW, and includes the Dutch, urban vs rural, etc. The worry is that the environmental effect has largely shot its bolt, raising the AA scores from 70 to 85.<br /><br />You can find writers on this topic who seem secretly gleeful about the lower scores of some groups, happy that their own white group is close to the top and enjoying that. I feel that tone in the comments sections at times, too - over at Taki's for example. But I think it's a horror. I'm hoping that there are still more points to find environmentally or because of test artifacts or the behavioral factors you mention. Ten points is a virtual erasure of the problem, and even five would give me hope. But The Gap has not changed since the 1960's.Assistant Village Idiothttps://www.blogger.com/profile/01978011985085795099noreply@blogger.comtag:blogger.com,1999:blog-19305198.post-52261943961746542282012-12-28T21:25:55.996-05:002012-12-28T21:25:55.996-05:00hmm... behavior = IQ in testing?

I completely agree (due to first hand knowledge) that brain injury (including brain tumors) can substantially reduce IQ. Oh... and aging. Aging truly sucks. <br /><br /><br /><br />Donna B.https://www.blogger.com/profile/16771075314473811594noreply@blogger.comtag:blogger.com,1999:blog-19305198.post-2918629353419944072012-12-28T13:30:21.721-05:002012-12-28T13:30:21.721-05:00One other thing to consider: Gaussian distributio...One other thing to consider: Gaussian distributions are an idealized model that match reality quite well when there are many factors in play, all of which are independent of each other and roughly equal in magnitude of effect. There's some reason to believe that the IQ distribution is actually fatter than Gaussian on the low end.<br /><br />That's because there are (sadly) many ways to reduce someone's IQ by 20 points (head injury, substance abuse, toxin exposure, malnutrition, etc.) but no known way to raise IQ by even half that. If group A is exposed to these negative stressors at a higher rate than group B, then applying a Gaussian model to the IQ distributions of both will show group A with a shifted bell curve, just like in your examples. Really, however, the two curves should look almost identical on the right half (A's being a bit lower vertically than B's), but the left half of group A's curve should be a different shape (higher and shallower sloped) than group B's. Remember, the IQ test itself is normalized (i.e. the "weight" of a right answer to a given question is set so that the overall results for the population is a normal = Gaussian distribution) so the published results of the tests will always <i>appear</i> Gaussian, even if the underlying "true" distribution is something else.<br /><br />The developed world has made huge strides over the last 100 years in eliminating some of these stressors (pellagra, chronic syphilis, birth injury, heavy metal exposure, and so on) and, indeed, the average IQ has steadily risen. Correlation, not causation... but still, quite a correlation! The "average" recruit to the US Army in WW I would test at 85 (mildly retarded) on modern tests, for example.<br /><br />I would also like to remind you of the example of the Irish immigrants to the US. In the 1800s, they were widely seen as congenitally stupid and semi-feral. But it was <i>all</i> due to dysfunctional behavior, notably substance abuse, petty criminality, chaotic sexual habits, and disrespect for education. When the behavior ended (that is, the Irish community no longer tolerated it), the "innate" intelligence differences disappeared. IQ measurements today show no difference between Irish and English IQs. That would have seemed ludicrous to someone in 1850s New York though.Laurahttps://www.blogger.com/profile/11602288826362438079noreply@blogger.com
