The idea that general intelligence may be more variable in males than in females has a long history. In recent years it has been presented as a reason that there is little, if any, mean sex difference in general intelligence, yet males tend to be overrepresented at both the top and bottom ends of its overall, presumably normal, distribution. Clear analysis of the actual distribution of general intelligence based on large and appropriately population-representative samples is rare, however… Expand

TLDR
The expected ratios of males to females at various points in the distribution are explored and the proportion of variance in general intelligence potentially due to genes on the X chromosome is estimated, providing clues to the extent to which biologically based sex differences could be manifested in the environment as sex differences in displayed intellectual abilities.

Sex differences in reasoning abilities: Surprising evidence that male–female ratios in the tails of the quantitative reasoning distribution have increased
Abstract Sex differences in cognitive abilities, particularly at the extremes of ability distributions, have important implications for the participation of men and women in highly valued andExpand
A Key Characteristic of Sex Differences in the Developing Brain: Greater Variability in Brain Structure of Boys than Girls
TLDR
Findings move beyond mean levels by showing that sex differences were pronounced for variability, thereby providing a novel perspective on sex differences in the developing brain. Expand
Sex differences on g and non-g intellectual performance reveal potential sources of STEM discrepancies
The analysis of sex differences in cognitive abilities is largely confusing because these differences are masked by the pervasive influence of the general factor of intelligence (g). In this study aExpand

Greater male variability has been established in cognitive abilities and physical attributes. This study investigated sex differences in variability in vocational interests with two large samples (NExpand
Sex differences in educational attainment
Abstract At the end of the 90s, Lynn knew that men have higher abilities and SAT scores. However, why then did females have higher grades in college? Analysing national databases and relevantExpand

Sex Differences in Intelligence: The Developmental Theory
It is a paradox that males have a larger average brain size than females, that brain size is positively associated with intelligence, and yet numerous experts have asserted that there is no sexExpand
Sex Similarities and Differences in Intelligence in Children Aged Two to Eight: Analysis of SON-R 2–8 Scores
TLDR
The results suggest that girls tend to mature earlier with respect to cognitive abilities and IQ scores during the course of development, however, the differences between girls and boys may become negligible. Expand
Gender differences in variance and means on the Naglieri Non-verbal Ability Test: data from the Philippines.
TLDR
Results on mean score differences support the hypothesis that there are no significant gender differences in cognitive ability, and the unusual results regarding differences in variance and the male-female proportion in the tails require more complex investigations. Expand

This paper argues that, provided samples are sufficiently large and complete, frequency-curves obtained exhibit small but significant deviations from strict normality, and, for most practical purposes, resulting distributions can be treated as approximately normal. Expand
