“… the ‘socialisation’ claim is that, left to their own devices, males and females would react identically to the same environments; and that the only reason why they systematically behave differently is that they are systematically exposed to different environments."
“There is scant evidence that parents, for example, do treat little boys and girls as claimed. Indeed, meta-analyses of studies in North America and Europe reveal that, if anything, parents discourage behaviour such as rough play and risk-taking more in young boys.”
“… girls and boys, even new-born babies, react differently when exposed to the same environments – unsurprisingly, given the scrupulous care with which natural selection has shaped them differently, from bodies to brains.”
“these sex differences occur in millions upon millions of other species, few of which even bring up their offspring at all, let alone teach them pink for girls and blue for boys".
