Boys are three times as likely as girls to need extra help with reading at primary school, and 75 per cent of children supposedly suffering from ADHD (attention deficit hyperactivity disorder) are male. “We are losing boys at a rate of knots, particularly in literacy,” Palmer says, “because at some point in the past 30 years, masculinity became an embarrassment.”

Research by Simon Baron-Cohen, a respected Cambridge professor, that began as an investigation into autism, puts a solid case for biological male/female differences in the brain, with boys tending to be “systematisers” and girls “empathisers”. This explains why boys generally are less keen on reading and comprehension, and lag behind girls in literacy. A lot of boys find it easier to explain the workings of a watch than to discuss how a character in a story is feeling. “But now,” says Palmer, “apart from the very bright ones, boys aren't even doing better at maths and science.”
