Science: IQ: A study of the intelligence of Kazakhs, Russians and Uzbeks in Kazakhstan

(008274.77-:E-001840.93:N-AV:R-SU:C-30:V)   

[Take note that the Russians have an IQ the same as Europeans. So I suspect that the Russians tested are largely of European origin. Though not all Russians are European. But it seems to me to be the preponderance of Russians – I suppose depending on where in Russia you are. The Kazahks, who are a Turkic people, have a lower IQ, more or less like Mixed race people.

Abstract

Data are reported for intelligence measured by the Standard Progressive Matrices Plus of school students in Kazakhstan. Ethnic Kazakhs obtained a mean British IQ of 82.2, ethnic Russians obtained a mean British IQ of 103.2, and ethnic Uzbeks obtained a mean British IQ of 86.0. The IQ of Kazakhstan is estimated at 87.3.

Factor analysis showed three factors identified as Gestalt Continuation, Verbal-Analytic Reasoning and Visuospatial Ability, replicating the analysis by Lynn, Allik, and Irwing (2004). The Russians performed significantly better than the Kazakhs in all age groups on Factor g and Factor 1 (Visuospatial Ability). There was no significant ethnic difference for Factor 2 (Gestalt Continuation) for ages 11, 12 and 13, although Russians performed significantly better than Kazakhs for age 10. The Russians scored significantly higher Factor 3 (Verbal-Analytical Reasoning) at ages 11, 12 and 13.
