well if the statistic says so, then he is right. based off my personal experience id say he is right.No he's trying to say its down to biological differences between men and women, when there's no evidence to suggest that and its almost definitely wrong anyway. The statistic is down to other factors. It is mainly to do with sociology and how girls are raised by their parents and treated at school etc. compared to boys, which leads to boys being more interested in tech.
I remember studying the differences in people in our biology lessons at school. There's two main categories for causes of differences: genetics and environmental. This is an environmental difference for sure.
