In the UK, immigrant groups frequently have lower mean socioeconomic status (SES) than do White British, which is a source of concern for the British government. Group-level SES tends to show positive relationships with cognitive ability scores. Thus, the authors estimate the mean cognitive and SES scores of various ethnic groups and test empirica...

In the Americas, less European-looking people have on average worse academic outcomes than more European-looking people. According to the colorism model, these associations between race-related phenotype and academic-related outcomes are due to contemporary phenotypic-based discrimination and not due to family-background or intergenerational facto...

Intelligence tests are excellent predictors of school and job performance, and racial/ethnic differences in mean IQ are common. Based on five lines of evidence, Warne (2021) builds a case for partly genetic causes of differences in general intelligence (g) across American self/parental-identified race or ethnicity (SIRE). Based on a careful reading...

In a recently-featured commentary, Winston [1] defined scientific racism as “the use of scientific concepts and data to create and justify ideas of an enduring, biologically based hierarchy” [1, p. 425]. Winston further argued that scientific racism persists because of the “social genealogy and history” of the research program, rather than becaus...

National IQ estimates are based on psychometric measurements carried out in a variety of cultural contexts and are often obtained from Raven’s Progressive Matrices tests. In a series of studies, J. Philippe Rushton et al. have argued that these tests are not biased with respect to ethnicity or race. Critics claimed their methods were inappropriate...

В статье анализируются исследования, посвященные влиянию макропсихологических параметров (например, средний коэффициент интеллекта) на экономический потенциал и развитие экономики государства. В статье представлены основные зарубежные исследования по выбранной тематике (поскольку это направление наиболее распространено в настоящий момент в англоязы...

The urgency of the researched problem is due to the new demands of society and the state on the resultsthat the general education system should achieve. Changes in the format of the FSESresults, establishedon the methodology of the system-activity approach, entail new tasks for teachersand students. Theauthors demonstrate theurgency of new goalsand...

Does lead reduce IQ at the level of g, test specificities, or both? A bare-bones psychometric meta-analysis uti- lizing the Method of Correlated Vectors was performed on a sample of 16 studies for which subtest-level data could be obtained satisfying stringent inclusion rules. The aggregate correlation across samples between subtest- level estimat...

Spearman's hypothesis simply states that differences between groups on an IQ test are a function of the general intelligence (g). At the item level this would mean the magnitude of the differences between groups are smaller on low-g-loading items and larger on items with a high g loading. An empirical test by Díaz, Sellami, Infanzón, Lanzón, & Lynn...

The problem of stability/dynamics of macropsychological characteristics based on the material of educational achievements of the regions of the Russian Federation considered. The relationship of educational results of the areas of the Russian Federation at the beginning of the XXI c. with literacy rates of inhabitants of the territories of these re...

The intelligence of Yakuts and ethnic Russians in Yakutia was tested with Raven's Standard Progressive Matrices Plus. According to British norms, the average IQ was 97.0 for Yakuts and 97.9 for ethnic Russians. Urban samples scored higher than rural samples.

The objective of this paper is to report a study of the intelligence of Yakuts and ethnic Russians in Yakutia. The samples were drawn from Yakutsk, the capital of the Yakutia region containing almost one third of the population of the province, and from Viluysk, a town with the population of approximately 10 600, which is situated 592 km north-west...

A sample of 28 Evenk/Tungus village children in the Russian Far East was tested with the Standard Progressive Matrices Plus and obtained a British IQ of 80. A sample of 13 ethnic Russian children growing up under similar conditions was tested with the same method and obtained a British IQ of 85. The results suggest that cognitive development of bot...
