What the study found was staggering: 100% of the 60 women of color who were interviewed reported experiencing gender bias in the workplace. Moreover, they experience a kind of double-dipped, double helping of biases based on both their gender and their race. They all shared experiences of discrimination in all forms, both subtle (micro-agressions) and overt.

The study highlights these staggering statistics:

100% of the women interviewed reported gender bias.
Black women are more likely (77%) than other women (66%) to report having to prove themselves over and over again.
The stereotype that Asians are good at science appears to help Asian-American women with students—but not with colleagues.
Asian-Americans reported both more pressure than other groups of women to adhere to traditionally feminine roles and more pushback if they don’t.
Latinas who behave assertively risk being seen as “angry” or “too emotional,” even when they report they weren’t angry; they just weren’t deferential.
Latinas report being pressured by colleagues to do admin support work for their male colleagues, such as organizing meetings and filling out forms.
Both Latinas and Black women report regularly being mistaken as janitors.
