He concluded, "No evidence was found for sex differences in the mean level of g. Males, on average, excel on some factors; females on others". Jensen's results that no overall sex differences existed for g has been strengthened by researchers who assessed this issue with a battery of 42 mental ability tests and found no overall sex difference.

The variability hypothesis, also known as the greater male variability hypothesis, is the hypothesis that males generally display greater variability in traits than females do. It has often been discussed in relation to human cognitive ability , where some studies appear to show that males are more likely than females to have either very high ...
The authors note that greater male variability is not ubiquitous, and ratios less than 1.0 have been reported in some national and international data sets. [10] A review by Hyde et al. (2009) also evaluated the topic of greater male variability in mathematics performance. [11]
In addition, the evidence regarding the existence of greater male variability is mixed, with some studies finding no sex difference in variability, or more variability in girls than in boys at some ages (Arden & Plomin, 2006; Harnqvist, 1997; Reynolds et al., 2008). Despite the lack of an appreciable sex difference in general intelligence ...
A 2017 review of amygdala volume studies found that there was a raw size difference, with males having a 10% larger amygdala, however, because male brains are larger, this finding was found to be misleading. After normalizing for brain size, there was no significant difference in size of the amygdala across sex. [26]
Although there are many physiological and psychological gender differences in humans, memory, in general, is fairly stable across the sexes.By studying the specific instances in which males and females demonstrate differences in memory, we are able to further understand the brain structures and functions associated with memory.
One other study also found greater female free-recall and long term retrieval among the ages 5–17. [20] In another study, when using multiple tests for episodic memory, there were no differences between men and women. [21] A similar result was also found among children from 3 to 6 years old. [22]
"Of the 80 disorders diagnosed in adulthood for which sex ratios are provided, 35 are said to be more common in men than in women (17 of which are substance related or a paraphilia), 31 are said to be more common in women than men, and 14 are said to be equally common in both sexes." [26] Differences in male and female jealousy can also be ...
