Women have smaller brains and therefore aren"t as intelligent as men: hormonal differences (men are violent because of testosterone) ex: gender testing in the olympics. Gender roles (men are doctors; women are nurses) Gender relations (doctors make a lot more money than nurses, who are female) Gendered institutions (families, schools, workplaces, places of worship reinforce traditional/conventional ideas about gender and work) On average, men and women biologically differ in many ways. Not im not saying that all men differ from all women in the following ways or that these differences are just . Im simply stating that the distribution of preferences and abilities of men and women differ in part due to biological causes and that these differences may explain why we don"t see equal representation of women in tech and leadership. You go for the biological excuse to maintain the inequality. Biological determinism: how things are structured according to gender.
