Intelligence: Is there a sex difference in IQ scores?

  title={Intelligence: Is there a sex difference in IQ scores?},
  author={Paul Irwing and Richard John Lynn},
Arising from: S. Blinkhorn Nature 438, 31-32 (2005); Blinkhorn replies.Steve Blinkhorncriticizes our study of samples of university students, in which we found that the average IQ of men is 4.6 points higher than that of women, as measured by the Progressive (or Raven's) Matrices. He maintains that there is a negligible sex difference in adult intelligence. We believe that the principal error of Blinkhorn's criticism is that he does not consider our result in the context of several other… 

Race and IQ: A Theory-Based Review of the Research in Richard Nisbett's Intelligence and How to Get It

We provide a detailed review of data from psychology, genetics, and neuroscience in a point-counterpoint for- mat to enable readers to identify the merits and demerits of each side of the debate over

Is there a sex difference in IQ scores? (Reply)

Irwing and Lynn explicitly claim to have identified a sex difference in IQ among university students1. They now counter2 my criticism3 of the flawed methodology upon which their conclusions are based

The role of height in the sex difference in intelligence.

The correlation between height and IQ and the female advantage in intelligence persist even after the authors control for health as a measure of genetic quality, as well as physical attractiveness, age, race, education, and earnings.

Whole Brain Size and General Mental Ability: A Review

The brain size/GMA correlations with age, socioeconomic position, sex, and ancestral population groups are described, which provide information about brain–behavior relationships and from an evolutionary and behavior genetic perspective.

Intelligence is negatively associated with the number of functional somatic symptoms

Intelligence is negatively associated with the number of FSS in the general population, and part of the association of intelligence with FSS is explained by a more unfavourable work situation for adults of lower intelligence.



Null Sex Differences in General Intelligence: Evidence from the WAIS-III

Given that the main ingredient of the strong association between IQ and a broad range of social correlates is g, and given that there is no sex difference in g, then the average IQ sex-difference favoring males must be attributed to specific group factors and test specificity.

Sex Differences in g

Sex differences in means and variability on the progressive matrices in university students: a meta-analysis.

A meta-analysis of 22 studies of sex differences in university students of means and variances on the Progressive Matrices disconfirm the frequent assertion that there is no sex difference in the mean but that males have greater variability.

Intelligence: A gender bender

The conclusion of a number-crunching exercise on various data sets is that male university students have significantly higher IQs than their female counterparts. But the methodology used is deeply

Methods of Meta-Analysis: Correcting Error and Bias in Research Findings

Psychometric Meta-Analysis helps clarify the role of bias, source Bias, and Publication Bias in research findings and provides a framework for correcting for these biases in future studies.
