Two groups of adolescents (N = 114), 61 identified-gifted adolescents (M = 22, F = 39) and 51 vocational school adolescents (M = 27, F = 26), were compared on the Overexcitability Questionnaire. Each of the five Overexcitability (OE) scores--Psychomotor, Sensual, Imaginational, Intellectual, and Emotional--was subjected to a two-way ANOVA by…

Beraldo (2010) and Cornoldi, Belacchi, Giofre, Martini, and Tressoldi (2010) (CBGMT) have eight criticisms of my paper (Lynn, 2010) claiming that the large north-south differences in per capita income in Italy are attributable to differences in the average levels of intelligence in the populations. CBGMT give results for seven data sets for IQs in…

Working with data from the PISA study (OECD, 2007), Lynn (2010) has argued that individuals from South Italy average an IQ approximately 10 points lower than individuals from North Italy, and has gone on to put forward a series of conclusions on the relationship between average IQ, latitude, average stature, income, etc. The present paper…

This paper examines the distribution of national IQ in geographical space. When the heritability of IQ and its dependence on eco-social factors are considered from a global perspective, they suggest that the IQs of neighboring countries should be similar. Using previously published IQ data for 113 nations (Lynn, R., & Vanhanen, T., (2006). IQ and…

When Congress passed the Individuals with Disabilities Education Improvement Act in 2004 (IDEIA 2004), local educational agencies (LEA) were permitted to use a Response-to-Intervention (RtI) approach for identifying children with possible learning disabilities for special education. Furthermore, IDEIA 2004 no longer required LEAs to establish an…

In this article, time effects on intelligence test scores have been investigated. In particular, we examined whether the "Flynn effect" is manifest in children from the middle and higher IQ distribution range, measured with a child intelligence test based on information processing principles--the Leiden Diagnostic Test. The test was administered…

Dissects the controversial Jensen paper, and concludes that Jensen is wrong. (DM)

Geneticists discuss the Jensen paper and suggest upon reviewing the evidence, that the question of genetic differences between the IQ of blacks and whites cannot be answered in the present circumstances. (DM)

Discusses how viewing intelligence as a learned skill and not a genetic gift may make the standard IQ test a thing of the pedagogical past. (GB/Editor)

Attempts to show that the purportedly scientific'' empirical basis of credentialism and I.Q.-ism'' is false; and to facilitate linkages between the groups who are being discriminated against the workers' movements within the white male labor force, by showing that the same mechanisms are used to divide strata against one another so as to…

The author suggests that more empirical evidence will have to be found before environmental influence can be declared insufficient to the cause of Negro-White I.Q. score differences. (Editor/RT)

This study investigated whether children oversized at birth, like those undersized at birth, have an increased chance of mental subnormality. Subjects were 4-year-olds born of urban disadvantaged white mothers whose average education was 10.8 years. Stanford-Binet intelligence scores of the subjects were compared to their birth weights. Between…

This study, with 496 children seeking admission to a special program for gifted preschoolers, found that creativity (as measured by the Thinking Creatively in Action and Movement Scale) was significantly related to intelligence (as measured by standard IQ tests) when IQs were less than 120 but was not related at higher IQ levels.

In January, W. H. Brady Scholar Charles Murray stepped back from current education debates about reauthorization of the 2002 No Child Left Behind Act and education funding in the president's budget to ask more fundamental questions about the goals that should shape American education in the future. This "On the Issues" is adapted from…
