Quillette asked a bunch of people who are in the fields quoted by darmore and they mostly agreed that the science quoted was accurate[1]. There is evidence to show that as economic equality increases, gender diversity skews more. That is, in poorer countries like India and Eastern Europe, women are more likely to work in tech to gain economic advantages. In countries where women are well off, they are more likely to pursue roles that are seen as feminine.[2], [3]
