In this Medium publication we showcase some of the interviews we conducted for the book Data Feminism (MIT Press, 2020). Data Feminism is a new way of thinking about data science and data ethics that is informed by the ideas of intersectional feminism. Today, data science is a form of power. It has been used to expose injustice, improve health outcomes, and topple governments. But it has also been used to discriminate, police, and surveil. This potential for good, on the one hand, and harm, on the other, makes it essential to ask: Data science by whom? Data science for whom? Data science with whose interests in mind? // Data Feminism will be released March 17th, 2020, but you can pre-order it here right now: https://www.indiebound.org/book/9780262044004
