Science is known for being objective and apolitical, but is it? Historically speaking, the voices of underrepresented groups have been missing from science, resulting in an often incomplete and fragmented perspective of the world. Without these voices, we are left with skewed ideas about race, ethnicity, class, sex, gender, and sexuality, how these concepts get made, and how they affect people’s lives. A new collection of essays published today in the Vital Topics Forum of American Anthropologist unpacks how increasingly diverse scientists speak back to these problems, by offering new and more complete understandings of human and nonhuman diversity.
