Five years ago, we published an episode about the boom in home DNA testing kits, focusing on the high-flying firm 23andMe and its C.E.O. Anne Wojcicki. Their flight has been extremely bumpy since then. This update includes an additional interview with the Wall Street Journal reporter who has been investigating the firm’s collapse.

Along with his collaborator Amos Tversky, he changed how we all think about decision-making. The journalist Michael Lewis told the Kahneman-Tversky story in a 2016 book called The Undoing Project. In this episode, Lewis explains why they had such a profound influence. SOURCE:Michael Lewis, writer.
