Annie Duke dropped out of a PhD program in cognitive psychology– and went on to win the World Series of Poker. At the Authors@Wharton Series, Adam and Annie discuss the evidence on when to pull the plug, delve into decision-making lessons from psychology and poker, and examine the difference between rethinking an idea and leaving it behind. Annie’s latest book “Quit: The Power of Knowing When to Walk Away” is out now. Transcripts for ReThinking are available at go.ted.com/RWAGscripts
