It's almost as if the way that men and womens brains have different levels of certain chemicals may affect certain traits and interests.... like how men are 400% more likely to have autism than women. Or how women have more oxytocin and vasopressin than men which are social hormones. And well... STEM fields aren't exactly the most social of fields. Just remember that you guys are only arguing about women in STEM fields currently and that there are mental/physical differences between men and women. You aren't arguing about ratio of waiters/waitresses, cashiers, or people that work in retail which are the most common jobs in America and also equally split gender-wise. You are seriously arguing about highly specific fields where having autism, tunnel vision, and task obsession are qualities that are both desired and seen. Women and men are different this is a fact, men have a larger inferior-parietal lobule(helps with math) than women while women have a bigger limbic system, men have more gray matter and women have more white matter. Women typically have weaker spatial abilities, or being able to mentally represent a shape and its dynamics. Women have a thicker parietal region of the brain, which hinders the ability to mentally rotate objects–an aspect of spatial ability. This spatial difference has also been shown in babies as early as 5 months old. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2651884/
Maybe, just maybe in the instance of STEM fields you may just be seeing the innate differences between men and women's leanings playing out.
