In certain academic circles today, stating the obvious has become a thought crime. Simply point out that men and women differ on average in their cognitive strengths, and you risk being branded a heretic, a sexist, or something worse. The American Greatness piece captures the absurdity perfectly: in woke academia and elite institutions, acknowledging well-documented sex differences in intelligence and abilities now qualifies as heresy.
Reality, however, remains indifferent to ideology. Decades of psychometric research, meta-analyses, and large-scale testing reveal consistent patterns. These are group averages with substantial overlap between individuals; plenty of women outperform most men in mathematics, and plenty of men excel as verbal superstars. Yet pretending the averages do not exist distorts science, education, hiring practices, and public policy.
The evidence is straightforward. On overall intelligence, as measured by the general factor "g" in full-scale IQ tests, men and women score essentially the same. Any minor average differences are small and debated. The more significant story lies in variability: males display greater spread in IQ and most cognitive traits. This produces more men at both the extreme high end: geniuses, top mathematicians, physicists, and chess grandmasters, and at the low end, with higher rates of intellectual disability and severe learning difficulties. Greater male variability helps explain why men continue to dominate Nobel Prizes in the hard sciences, Fields Medals, and elite technical fields, even when average IQs are comparable. This is not oppression; it is a statistical reality replicated across studies.
Specific cognitive strengths also differ. Males tend to outperform females on spatial abilities, particularly mental rotation (visualising three-dimensional objects turning in space), mechanical reasoning, and certain advanced mathematical tasks. Recent analyses confirm a male advantage in geometry and broader mathematics that becomes more pronounced in later school years and high-level content. Females, by contrast, tend to outperform males on verbal abilities: reading comprehension, writing fluency, language processing, and verbal memory. Girls lead in literacy from early ages, a pattern that persists.
These differences are not social constructs that dissolve under equity training. They emerge early in life, appear across cultures (with varying magnitudes), show clear biological correlates such as prenatal hormone exposure and brain structure variations, and align with evolutionary pressures: males historically navigating territory and hunting, females coordinating socially and rearing children.
Modern academia treats sex differences as radioactive. Journals and universities elevate the "gender similarities hypothesis" while downplaying or contorting contradictory data. The reasons are predictable: ideological capture, where equity ideology demands identical outcomes and views any innate difference as a threat to the blank-slate narrative; policy implications that make aggressive quotas and "patriarchy" explanations harder to sustain if biology plays a role in fields like elite engineering or nursing; and career incentives that subject studies affirming differences to extra scrutiny or outright cancellation risks.
The result is a parade of tortured explanations: stereotype threat, patriarchal socialisation, lack of role models, offered even for patterns that persist in highly egalitarian Nordic countries. In the real world, male dominance in top STEM fields and female dominance in humanities, education, and verbal domains continue to match the data.
Ignoring these differences does not make them vanish. It produces misguided education policies that treat boys and girls as interchangeable, affirmative action schemes that lower standards in domains requiring extreme spatial or mathematical talent, and widespread frustration when individuals fail to fit the "everyone is the same" myth. Resources are wasted chasing perfect 50/50 representation instead of allowing people to pursue their natural strengths.
The honest approach is simpler: recognise the averages, celebrate individual variation, remove artificial barriers, and abandon the drive for identical outcomes. Men and women are complementary rather than identical. That is not heresy, it is basic evolutionary biology and psychometrics. Society functions best when it works with human nature instead of waging war against it. Denying sex differences in cognition is merely the latest chapter in the long, failed experiment of pretending biology is optional. It isn't.
