Why medical students are advised - if you hear hoofbeats behind you, don't expect to see a zebra. In his guide to thinking better, Professor Steven Pinker explores Bayesian reasoning.

Steven is joined by Talithia Williams, professor of mathematics at Harvey Mudd College and author of ‘Power in Numbers The Rebel Women of Mathematics’, and by Siddartha Mukherjee, professor of medicine at Columbia University and the author of the Pulitzer Prise winning ‘The Emperor of All Maladies A Biography of Cancer’

Together they’ll help you evaluate ideas, recalibrate your credences and maybe even think a little better.
