Sex differences in social capital are differences between men and women in their ability to coordinate actions and achieve their aims through trust, norms and networks. [51] Social capital is often seen as the missing link in development; as social networks facilitate access to resources and protect the commons, while cooperation makes markets ...
The human brain. Differences in male and female brain size are relative to body size. [82] Early research into the differences between male and female brains showed that male brains are, on average, larger than female brains. This research was frequently cited to support the assertion that women are less intelligent than men.
The neuroscience of sex differences is the study of characteristics that separate brains of different sexes. Psychological sex differences are thought by some to reflect the interaction of genes, hormones, and social learning on brain development throughout the lifespan. A 2021 meta-synthesis led by Lise Eliot found that sex accounted for 1% of ...
Sex differences in human intelligence have long been a topic of debate among researchers and scholars. It is now recognized that there are no significant sex differences in average IQ, [ 1][ 2] though particular subtypes of intelligence vary somewhat between sexes. [ 3][ 4] While some test batteries show slightly greater intelligence in males ...

For example, the human "sex difference" in height is a consequence of sexual selection, while the "gender difference" typically seen in head hair length (women with longer hair) is not.
The XY sex-determination system is a sex-determination system used to classify many mammals, including humans, some insects ( Drosophila ), some snakes, some fish ( guppies ), and some plants ( Ginkgo tree). In this system, the sex of an individual usually is determined by a pair of sex chromosomes. Typically, females have two of the same kind ...
v. t. e. Sex differences in cognition are widely studied in the current scientific literature. Biological and genetic differences in combination with environment and culture have resulted in the cognitive differences among males and females. Among biological factors, hormones such as testosterone and estrogen may play some role mediating these ...
