AI can tell a person's sex from brain scans with 90 per cent accuracy

Men's brains tend to be larger than women's, which makes them difficult to compare Are men's and women's brains all that different? A new way of investigating this question has concluded that they are – but it takes artificial intelligence (AI) to distinguish between them. The question of whether we can measure differences between men's and women's brains has long been contentious, with previous research coming up with contradictory results. One problem is that men tend to have slightly larger brains than women, probably because they generally have larger bodies, and some previous studies that compared the size of different small regions of the brain failed to adjust for the overall brain volume. However, even doing so hasn't previously resulted in clear-cut findings.
