Here’s an article about gender that actually makes sense; I’m looking forward to the book, even.
“If you map the distribution of scores for verbal skills of boys and of girls you get two graphs that overlap so much you would need a very fine pencil indeed to show the difference between them. Yet people ignore this huge similarity between boys and girls and instead exaggerate wildly the tiny difference between them. It drives me wild,” Plomin told the Observer.
Again: there’s more similarity than difference between genders.
