Are you sure this is the link you want?
Yes. Scroll down past the cute pictures. There is a list of articles with links. I was too lazy to summarize them all; I guess I should do so. . . .
Hope this one gets published – The poor availability of research data for reanalysis has just become much poorer.
K?
I enjoyed "Why national IQs do not support evolutionary theories of intelligence."
"To enable a comparison to the literature, we employed Lynn and Vanhanen’s estimates of national IQ in countries that have mostly indigenous inhabitants (in line with Templer & Arikawa). We ex-
cluded Equatorial Guinea, because the IQ data that were used by Lynn and Vanhanen (2006) were erroneously based on a sample of mentally retarded children from Spain."
That's some fine research he's commenting on there.
More generally, how can anyone bear to work in the field of IQ research? The politics are so loathsome and the uses the results get put to so awful I don't know how people can stand it…
I think the pictures are just to show that all his children are above average ;)
Andrew, summarizing is time consuming — but perhaps you could pick: if I could only read one or two, what one or two would those be?
Anne, you make a good point about the general problems in this area. Is there any other area of psychological research so filled with @#$% for so many decades? I hope not.
But it's an important area, and it's important for good people to stay active in it — if only to serve as @#$% detectors.
For what its worth, I made some similar points about Kanazawa's "evolutionary theories of intelligence" in J.Evolutionary Psychology last year, vol 7(4). I was particulary taken with his implicit assumption that the earth was flat. Intelligence, which published the original paper, rejected mine preferring to publish a paper they knew had serious flaws and keeping their readers in the dark about it.
This whole area is rife with loose theorizing, poor data & careless data analysis which discredits the whole literature, which is a shame.
There is also now a mini-industry pointing out numerous flaws in Kanazawa's work (& without response as far as I know). I think the best solution is simply not to read it.
National IQ will never support theories of intelligence. The IQ system is fundamentally flawed and takes into no account the creative aspect of a person, which is what enables human problem solving capabilities to vastly exceed those of other primates.The only thing they accomplish is how westernized and IQ test literate a country's populace is or is not.

Not true.
Considerable effort has gone into producing nonverbal IQ tests that can be used in
any culture. These “culture-fair” or “culture-reduced” IQ tests have been shown to
predict important life-outcomes with validity coefficients comparable to traditional IQ
tests designed for specific populations (Court 1991; Kendall, Verster, & Von Mollendorf…
Unlike other measures of human
capital such as reading comprehension and mathematical reasoning tests, culture-fair IQ
tests have no literacy prerequisites. Because the tests are nonverbal, the test items are the
same for everyone and thus results are more comparable across language groups and
cultures.'
