From Sleep in response to my post on Israeli achievements and IQ:

“Im curious. What do you think the average intelligence might be of the following groups:

Jews in Israel of European origin (Ash/Seph or other)
Mizrahi Jews
Palestinian Arabs”

ARABS:

Let’s compare them to other Arab states. Egypt is 83. Lebanon is 86. Morocco is 85. Iraq is 87. Qatar is 78. That seems to be the Arab range: 78-87. I haven’t seen any Arab countries score in the 90s and only Qatar is in the 70s. The average of the 5 Arab countries listed by IQ and the Wealth of Nations is 83.8, so the Palestinians are probably around 85. Whether it’s a couple points more or less is irrelevant, just a margin of error, and at the same time, I doubt that they are above 90 because no other Arab country is.

ASHKENAZIM

The pure-blooded Ashkenazim score probably the same as they do elsewhere 112-115.

However, many Israelis identifying as Ashkenazi are half or at least a quarter Mizrahi. I would estimate that if you count anyone who self-identified as Ashkenazi, regardless of their ancestral mix, the Israeli “Ashkenazism” would be 108-110.

MIZRAHIM (Jews from Muslim nations who adopted the Sephardic religious traditions)

It is established that they score about a standard deviation lower than that of the Ashkenazi Jews. They also outscored their Arab neighbors, had more intellectually challenging jobs, and earned more money.

One test showed a gap of 14 points between the Ashkenazim and the Mizrahim in Israel. Note that the description is one of self-definition, so many of the Sephardim are partly Ashkenazi and the reverse.

My estimate for people of exclusively Mizrahi background would be about 90. If you include everyone who self-defines as Mizrahi, it would probably be about 95.

So if all Ashnkezim are 109 and the gap is 14 points, then the average self-defined Mizrahi is 95, which also coincides with other estimates (Israeli Ashkenazim being as smart as Ashkenazim elsewhere and Mizrahi being a little above the Arab average).

The Jewish average therefore becomes 102.

The average for all Israelis, including the Arabs would therefore become 99.

Note that this is a confusing and non-scientific way of doing it.

The mixed Ashkenazi-Mizrahi people shouldn’t be classified genetically as they choose, but instead should be part of the same group.

If you take them out, the gap between them grows from about 15 points to about 20-25, whereas the mixed Ashkenazi-Mizrahi people would average about 100.

The Israeli job market and education rates reflect it.

I wrote before that the estimation that Israel’s IQ is 94 is wrong.

Here’s a video on Israeli achievements. If IQ tests show Israel having a low IQ, it must be a bad test. This may sound really bad, but what I mean is that if a nation can have so many intellectual achievements, it cannot have a low average IQ. But as I argued before, Israel does not have a low IQ, Prof. Lynn just decided to discard the three tests with the highest results and then used two other tests from which he subtracted 2 points.

According to this video, Israel has:

  • The most patents per capita;
  • The most engineers and scientists per capita;
  • The most scientific papers per capita;
  • The second highest book publishing per capita;
  • The most museums per capita;
  • The highest concentration of high-tech companies per capita and second highest in total numbers;
  • One of only 8 nations with a space program;
  • Israel has the world’s largest research center;
  • The most per capita and third overall after US and Canada among companies traded on Wall Street.

Israelis developed the first cell phone, voicemail, text messaging, ICQ instant messangers, network firewalls, Intel Centrino and Pentium 4, the first anti-virus software, the first solar power plant. (A whole bunch of other stuff like phenomenal tanks and nuclear weapons. They are #3 in college degrees and #1 in graduate degrees.)

If you can do all that, how can you possibly have a low IQ? Such claims, while popular in certain corners (the anti-IQ left and the antisemites), are just not credible.

Prof. Lynn should’ve discarded the lone test that showed Israelis with an IQ under 100 (it had an average score of 92) as an outlier. Instead, he discarded three tests showing Israel averaging triple digits, even when including the Arabs and the Sephardim, and then subtracted 2 more points. Such creative math may convince the uninformed, but those who are aware of the above list of Israeli intellectual accomplishments will have trouble believing that it is a low IQ nation.

Try to solve this math problem: (100+100+100+100+92)/5. You would think the answer would be 98.4. But not according to Richard Lynn who counted this to be 94.

It has been widely cited on the internet that Israel’s average IQ is only 94. But how did Prof. Lynn arrive at the figure?

First, he threw out three tests showing Israelis averaging 100. Then he took the two remaining tests and shaved off two points, even though most nations got additional points due to the Flynn Effect and other factors.

The reality is that he should’ve dumped the test that showed that Israelis scored only 92 on a test. It is what statistians call an outlier. In statistics, an outlier is an observation that is numerically distant from the rest of the data and for that reason it is generally discarded. For instance, if all the opinion polls showed Barack Obama winning by 5% and one poll showed McCain up 4%, you would discard the pro-McCain poll as an aberration.

Similarly if 4 out of 5 tests of Israelis show an IQ score of 100 and one is significantly below that, that lone test should be discarded.

Instead, Lynn turned 92 into 90 and 100 into 98, discarded three others tests, and came up with a very low number of 94. It is mind-boggling to think that when 4 out of 5 tests give an IQ score of 100, he somehow manages to give Israel an average score of 94!

Lynn also gives the lowest IQ estimate (107) of anyone for Ashkenazi Jews living in the United States.

Now let’s look at the data.

A test of Israeli school children resulted in an average IQ of 100. The Israeli military conducted two tests, one of which was a highly g-loaded adaptation of the Raven’s Matrices, both showing soldiers with an IQ of 100. [S. Kaniel and S. Fisherman, “Level of Performance and Distribution of Errors in the Progressive Matrices Test: A Comparison of Ethiopian Immigrant and Native Israeli Adolescents,” International Journal of Psychology, vol.26, 1991, pp.25-33; J.R. Flynn, “Israeli Military IQ Tests: Gender Differences Small; IQ Gains Large,” Journal of Biosocial Science, vol.30, 1998, pp.541-553.]

In Israel, almost all Jews – male and female – are drafted into the military, so it is not a specially selected group.

At the time when these IQ tests were conducted, a majority of Israeli Jews were Sephardic who score about 14 points less than Ashkenazic Israelis. All the IQ tests were conducted prior to the arrival of a million mostly-Russian Ashkenazi Jews after the fall of the Soviet Union. At the time, less than 30% were full-bloodied Ashkenazim without any Sephardic ancestry. More than 70% of Israelis were Arabs, Sephardim or a mix of Sepharim and Ashkenazim. After the wave of Russian immigration, about 35% of Israelis are Ashkenazim without any Sephardi ancestry.

If you count anyone who self-identified as Ashkenazi as such, their average IQ would be about 107-110. [If the average IQ is 100, and Ashkenazim outscore the Sepharim by 14 points, and the two populations are equal in size, then Ashkenazim must score 107 and Sephardim 93. However, since Sephardic population was greater than Ashkenazi at the time of these tests, the former’s IQ must be somewhat higher than 107.]

But why is the Israeli Ashkenazi IQ lower than the American Ashkenazi IQ of 113-115?

Because, as noted, many of the self-identified Israeli Ashkenazim are actually half or at least a quarter Sephardic. Just take a look at the average Israeli Ashkenazi – many are clearly partly Sephardic. Living in a country where most of the population belongs to a different group, and where you feel no compulsion not to marry that group will result in significant intermarriage.

With the arrival of a million Ashkenazim from Russia, one can be pretty certain that the average Israeli Ashkenazi IQ has temporarily gone up because Russians rarely intermarried with Sephardim.

But as Sephardic and Ashkenazi Jews in Israel intermarry, the former will raise their average and the latter will drop.

Finally, the idea of Israel having a low IQ is inconsistent with other facts. In proportion to its population, Israel has the largest number of startup companies in the world. In absolute terms, Israel has the second largest number of startup companies (3,500) after the United States, an amazing feat considering that several European countries have a population ten to fifteen times that of Israel, and the high IQ China has 200 times as many people.

Israel is third in the world in college degrees and first in graduate degrees. Israel has the world’s second highest per capita rate of publishing new books and has more museums per capita than any other country, as well as the highest percentage of home computers. Israel produces more scientific papers per capita than any other nation by a large margin.

None of these facts are consistent with Lynn’s claim of a low Israeli IQ.
