One of the things we assign to science is that there are true, absolute facts. But scientists are human and, it turns out, as prone to blind spots in their thinking as the rest of us, especially when cultural assumptions and biases get in the way. Biologist Christina Agapakis explores ways these blind spots, especially around gender and sexism, have affected research and women’s careers in science. She talks with one of her heroes, anthropologist Emily Martin, and Emily's husband, biophysicist Richard Cone, about Emily's 1991 article "The Egg & The Sperm." She also talks with anthropologist Kate Clancy, who has spent a lot of time thinking and writing about the ways women’s careers in science are different from men’s.
