social pressure
women and girls are actively discouraged from engaging in math & science by:
teachers (dont sweat it honey, you'll make a smart man very happy with those looks)
men (i dont want to be with a smarter woman because it makes me feel inferior)
women (ew who wants a dorky nerd girl, borinnnng)
you get all that in math class as a 12-year old girl and yeah you start to associate math with unhappiness
The only difference between bigotry and compassion is attribution of cause.
Women are usually worse at math and science than men. Absolutely true fact. But why?
See also: Racial minorities being poorer, worse educated, and more inclined to steal. It's true! Now tell me why it's true. Trans people have higher rates of mental illness, self-harm, and suicide. No argument that this is true, it's rampant. But why is it true?
