I am puzzled when I encounter disbelief from colleagues, male and female, about glass ceilings and discrimination in academia. "Didn't you, as a female scientist, make it here?", they ask. Yes, I did. But it's hard to do a control experiment with myself and ask how things might have been different had I been a male scientist. It's generally difficult to make trend predictions based on singular or few data, but a systemic analysis indicates widespread gender disparities in various aspects of academia, from percentage of women graduate students, likelihood of getting published with a female name, or through the tenure process. Discrimination, unconscious or otherwise, acts along multiple axes, and issues of ethnicity/race, socio-economic class, sexual orientation, age, physical appearance, and nationality mix with gender to create multiple and complex levels of prejudice.
