**update 08/12 – see below**

i’m using unbelievable in two senses of the word here: 1) that what run unz says cannot be believed, and 2) i can’t believe the things ron tries to get away with! (see what i did there? (~_^) )

an example of point 1:

ron said wrt the buj iq studies that appear in lynn and vanhanen’s IQ and the Wealth of Nations (tWoN):

“As it happens, all three of those near-100 IQ studies from 1979 are part of the 19 national samples contained in the Buj (1981) collection, which tend to be extreme outliers in all the various countries. Supposedly, the Buj IQ studies were totally non-representative and were generally conducted in capital cities, which might help explain why usually they often tend to be 10-15 points higher than other IQ studies from those same countries.”

frank pointed out that this is simply not true. and frank is right. i just went through steve sailer’s table summarizing the results of tWoN (thanks for the link, frank!) and picked out all the nations included in the buj study. here are all of the adjusted iq scores for each of those countries as found in tWoN:

Austria
103 – Moyles
101 – Buj

Belgium
103 – Goosens
99 – Goosens
98 – Buj

Bulgaria
94 – Buj
91 – Lynn, Paspalanova

Czech Rep/Czechoslovakis
98 – Buj
96 – Raven

Denmark
99 – Buj
97 – Vejleskov

Finland
98 – Kyostio
96 – Buj

France
102.5 – Dague
96.5 – Bourdier
94 – Buj

West Germany
107 – Buj
105 – Raven
101 – Raven
99 – Winkelman

**Ghana**
80 – Buj
62 – Glewwe

Greece
95 – Buj
88 – Fatouros

Hungary
99 – Buj

Ireland
98 – Buj
87 – Raven

Italy
103 – Tesi
101 – Buj

Netherlands
107 – Buj
101 – Raven
99 – Van Bon-Raven

Norway
98 – Buj

**Poland**
106 – Buj
92 – Jaworowska

**Portugal**
101 – Buj
88 – Simoes

Spain
98 – Buj
96 – Raven
90 – Nieto-Alegre

Sweden
104 – Buj
97 – Skandinaviska

Switzerland
102 – Raven
101 – Buj
99 – Raven

i’ve highlighted the nations where the buj scores seem to be “extreme outliers,” i.e. in which the buj scores are 10-15 points different from other iq tests done in those countries, and I only find three (3) examples: ghana, poland and portugal. if i were feeling generous, i might throw in ireland, too, with a nine (9) point difference. that’s hardly what i’d call “often.” quite the opposite — in the vast majority of the cases, the buj scores align very nicely with other test scores.

i can’t see how ron unz couldn’t have been aware of this since he’s apparently spent so much time combing through the lynn and vanhanen data. either he forgot what was really in tWoN, or … i dunno … he’s being economical with the truth? whatever the case — and given all the other “careless errors” he’s made with the data — ron is…

unbelievable.

an example of point 2:

wrt his original data collection from the gss on how rural or urban different white american ethnic groups are, ron said:

“As for my GSS calculation, I just used RACE=WHITE, ETHNIC, and WORDSUM. My ethnic urban/rural estimate substituted RES16 for WORDSUM, and I considered Country+Farm as being ‘rural’ while ‘City+Suburb+Big City’ was considered urban. The Italians, Irish, Greeks, and Yugoslavs come out heavily urban, the Dutch heavily rural, and the Germans somewhat rural.”

i should’ve paid more attention to this at the time, ’cause now just the other day, dan pointed out (thanks, dan!) that ron just SKIPPED a whole gss category of rural/urban folks, namely the small town folks [quote from here]:

“My analysis only focused on the City/Suburb/Farm categories (leaving out e.g. small towns), since those seemed to provide the sharpest sign of some sort of surprising Rural/Urban Divide.”

why would you leave out a WHOLE CATEGORY OF THE DATA?

perhaps that’s the reason that, unlike ron, i found that german-americans are not significantly more rural than other white american ethnic groups. ’cause i used ALL the data available in the gss.

who knows what else is “not quite right” with ron’s data points given his selective use of them (plenty examples of which have already been pointed out many, many times over in the comments here on this blog — thanks to everyone who’s drawn attention to these little problems in ron’s methodology!)?

unbelievable.

update 08/12: i’m gonna just go ahead and add one more point — the constantly shifting sands of ron’s argument.

in my first post about ron’s iq theory, i said that one point that needed to be taken into account is exactly who are taking the iq or pisa or whatever tests. i pointed out that:

“today’s french’ population includes ca. 19% (11.8M) foreign born immigrants or their direct descendants, about one-third (4M) of whom are from north africa. and the u.k. had 7.86% minorities as of the 2001 census (and it’s well known that those rates have gone up since then)…. it’s very possible that the average pisa/iq scores of ethnic french or british kids are higher than their current national scores….

“you don’t think the immigrants in these countries could bring down the pisa scores? think again. the irish have actually experienced this even with the comparatively small number of immigrants they have….” [see the previous post for the full example.]

ron dismissed that the presence of large numbers of immigrants could have any significant effect on iq/pisa scores in france or britain — or anywhere, i guess:

“You argue this might be explained because 20% of France’s population were low-IQ minorities, and the 8% of Britain’s population fell in the same category. Does this make any sense? Could a British population which was 92% high-IQ and 8% low-IQ really have the same average academic performance as an Irish population which was 100% low-IQ?”

now, in the comment thread of this very post (!) — just down there ↓ — ron says:

“The fifth widest gap is the 8.5 spread for France, with the *low* score being from Buj (but note that by 1979 France’s capital city of Paris already contained a substantial population of impoverished African and North African immigrants).”

!?!?!?!?!?!

well, which is it?! can a good-sized population of immigrants affect iq scores or not?? it’s hard to tell when you’re discussing a problem with ron unz. shifting sands, shifting sands.

here’s another example of this: ron’s original argument, if you’ll recall (and iirc), involved the “facts” that british-americans and dutch-americans are both very rural groups and that they have, comparatively, low iqs. when it was made clear to him that british-americans don’t have comparatively low iqs, he suddenly changed his tune:

“A much better example I should have used instead were German-Americans, who are significantly more rural than the white American average….”

only they’re not. see also point number 2 above.

shifting sands, again. unbelievable.
