EPISODE DESCRIPTION
Michael Kearns is a professor at University of Pennsylvania and a co-author of the new book Ethical Algorithm that is the focus of much of our conversation, including algorithmic fairness, bias, privacy, and ethics in general. But, that is just one of many fields that Michael is a world-class researcher in, some of which we touch on quickly including learning theory or theoretical foundations of machine learning, game theory, algorithmic trading, quantitative finance, computational social science, and more.

EPISODE SUMMARY
In this episode of Lex Fridman Podcast, featuring Lex Fridman and Michael Kearns, Michael Kearns: Algorithmic Fairness, Privacy & Ethics | Lex Fridman Podcast #50 explores designing Fair, Private Algorithms Without Letting Machines Define Morality Michael Kearns and Lex Fridman discuss how to formalize ethics—especially fairness and privacy—inside algorithms without asking machines to decide what is morally right. Kearns explains the technical progress and limits of algorithmic fairness, contrasting its messiness with the more mature framework of differential privacy. They explore trade‑offs between accuracy and fairness, individual versus group protections, and how social media and financial systems illustrate game‑theoretic dynamics. Throughout, Kearns stresses that society must define the norms; computer scientists should encode and expose trade‑offs, not quietly choose our values for us.
