All I know is, where I grew up, girls usually scored higher than boys on math tests, and of course that was also attributed to physical/gender differences... girls having a "natural" interest in studying and boys having a "natural" interest in running around and being boys. Everything always gets blamed on gender differences but the truth is, we simply don't know what those differences are (as opposed to culture/individual upbringing), so we justify our own prejudices with "science".
