Why are men better at science and math than women?

They aren't. It has to do with it not being seen as feminine. I myself am a girl and love math and science. We're all equal.

first of all, that isn't true. males have bigger brains because they have a bigger build but that doesn't necessarily mean that males are smarter than females.

Because patriarchy.

Also, I'm retarded.

Women are so concerned about sexuality and mating they forget there's other things out there.

iron deficiency

iron levels in the brain are known to be linked to a child's developing abilities in math and science skills

many girls suffer anemia during puberty, because their diet isn't iron-rich enough to compensate for blood loss from menstruation.

parents can easily correct the problem by adding additional meat, fish, eggs, etc. to their daughters' diet at the start of puberty.

It is a matter of interest - more men than women are interested in such things, especially math. For the ones who are interested the level of skill is very similar.

They aren't. Why are you drunk?

They aren't, necessarily. Studies show that girls tend to lose interest in math and science in middle school, largely because it's not seen as feminine or attractive for girls to study those things. Some research on the SAT test showed that females made the same scores as males when they were given more time- it was lack of confidence in their math skills that made them check and re-check their work. There are, by the way, more women graduating from medical schools now than men, so they must have been good at science.

They are not. It is a stupid generalization which has been disproved many times.

yes
