The problem is that the neuroscience side has some studies that have generated some debate, so I only wanted to mention that nature plays a part in these differences, as well as a nurture. In the notes, I did link to a general article on physical differences in our brains. However, there are competing studies that argue these differences aren’t a big deal.

In addition, there is a study that shows a correlation between testosterone levels and spatial ability test scores (explaining perhaps why a smaller number of women with higher t-scores become engineers compared to men), but there are also people who question the methodology of the tests and argue that results are skewed by a number of psychological factors
