We talk a lot on this show about the unintended consequences of using technology, and who is harmed by that technology. Marketplace’s Marielle Segarra speaks with a scholar who thinks about this a lot: Safiya Noble. She’s an associate professor of gender studies and African American studies at UCLA. Noble is also the author of the book “Algorithms of Oppression: How Search Engines Reinforce Racism,” and a 2021 MacArthur fellow.
