If you want to choose a career that helps other people effectively, which should you pick? Medicine? Research? Non-profit? The answers may not be as straightforward as you think. This episode of Rationally Speaking features special guest Benjamin Todd, the co-founder and executive director of 80,000 Hours, an organization devoted to helping people choose career paths to do good better. Ben, Massimo and Julia debate the heuristics that should go into career choice, utilitarianism vs. virtue ethics, and what exactly we mean by "doing good."
