Uvek me zanimalo kako se dođe do prosečnog IQ u nekoj državi ili naciji? Ko je testirao stanivništvo ili deo stanovništva kao uzorak, pa je došao do rezultata? Koliko znam, na jedino priznato testiranje koje meri IQ ljudi se prijavljuju dobrovoljno i to su uglavnom dobri rezultati. Zatim, na testiranju se ne dobijaju tačni rezultati, već "od - do".
Izvinjavam se na ofu, ali često nailazim na "prosečan IQ" neke nacije, pa me zanimalo...
Neka dvojica psihologa ultra desne orijentacije su napisala knjigu
Odatle dolazi 90% novinskih članaka koliki neka nacija ima IQ,
Uzorci su takvi da za neku naciju imaju test koji je radilo 12 ljudi, dok za neke nacije i nema test, nego su oni slobodno procenili računajući proseke susednih naroda...
Evo kako su dobijani rezultati za pojedine zemlje:
Example: to establish the average Iq of 25,000,000 Canadians the authors base their values on ** ONE ** sample of ** 313 ** canadians aged ... 7 to 12 years (!) and taken in ... 1979 !!!.
There is not even a mention if the sample is a random sample or if it was taken in a poor or rich suburb, or in a rural or city area, etc, which means in all likelyhood it was unlikely to even ba random sample, or worse the authors didn't seem to realise that this inadequacy would invalidate the whole study.
Many other countries IQ are similarly based on 1 or 2 old non-representative studies.
Vietnam's IQ is listed as 96 despite the fact that he didn't do any actual work on the survey. He collected the data he found from China 100 and Thailand 91 and took the average to be 96 for Vietnam. I showed this to a statistician by profession and he said he has never seen such way of doing surveys, particularly this type of surveys. Now go to the same list on the top that shows Afganistan 83. the star(*) next to it shows that it is taken by averaging Iran-84 and India-81. How funny and full of flaws is this?
He also gave Armenia the IQ of 93 ( by averaging Russia's 96 and Turkey's 90) because a countries IQ average can be calculated by averaging the Iq of its neighboring countries of course(sarcasm intended)
Tests on immigrants, given in the language of the receiver country, are taken seriously. It is quite standard in the area where I live to test monolingual-Spanish-speaking children in English. Yet the authors' lowly IQ for Mexico (84) is based partly on tests of immigrant children. The authors admit that some of their Turkish data is derived from tests in Dutch, in the Netherlands, on recent immigrants. Yet they take these results seriously (though they discard the "vocabulary" part of the Dutch test). Much of the assessing was done by the Raven "nonverbal" test, which is prone to experimenter error.
Znači potpuno smeće sa stanovišta statistike i nauke uopšte već preko 10 godina puni naslovne strane u novinama i onda debatujemo ko je glup ko je pametan, pa čak i političari citiraju rezultate..
Mada možda je direktno povezano.
