Men and women: what the brain does and does not tell us
People have weighed and scanned brains for 150 years to explain the differences between men and women. This course asks what the measurements show: how big the differences are, how much they overlap, which popular claims have held up, and what that means for talking, marrying, and working together.

- 1 Two kinds of brain?For 150 years people have weighed and scanned brains to explain the sexes. What the measurements show: size, hormones, wiring, and why most brains turn out to be a mosaic.
- 2 How big is a difference?Spatial skills, words, numbers, and the very top of the scale. How large the gaps are, how much they overlap, and what changes them over time and from place to place.
- 3 Talking, feeling, staying togetherDo women talk more, read people better, and remember every wrong? What recorders and tests found, and what thirty years of watching couples argue can and cannot tell us.
- 4 Working togetherLeadership, competition, negotiation, trust, and mixed teams: what the evidence says about how men and women work, and how to bring out the best in both.
You’ll be able to
- Describe what brain studies measure in men and women (size, structure, hormones, connections), say how large the differences are once head size is taken into account, and explain the “mosaic” critique.
- Use effect sizes, overlap, and spread to judge a claim about men and women, and tell abilities where the gap is large, small, or changing (spatial rotation, language, math) from claims that did not survive checking.
- Explain what research finds about talking, empathy, and “women’s intuition,” and what studies of couples’ conflict can and cannot say about why marriages last.
- Weigh the evidence on leadership, negotiation, competition, trust, and mixed teams, and separate an average difference from a prediction about one person.
About this course
This course covers 男女之别 (Differences Between Men and Women), the part of cognitive neuroscience and psychology that asks how the brains, abilities, and habits of men and women differ. It sits beside Course 9, Sex, love, and romantic relationships, which told the evolutionary story of mating and marriage, and Course 10, Thinking, fast and slow, on the shortcuts of the mind. Here we do not ask where our wants came from. We ask what the measurements show, and how far they can be trusted.
The argument and examples lead. Around them we add the primary research behind each claim, the critiques of it, and findings from China and the United States side by side. This is a subject where popular claims run far ahead of the data, so each lesson reports how big a difference really is, how much the two groups overlap, and which famous results failed when other laboratories tried again. Where the course’s own examples were unsupported, we have replaced them with what the studies found.
