Why do smart groups make dumb decisions and what can you do about it?
In this episode of Second Thoughts, Dr. Roger Hall breaks down the psychology of groupthink: the invisible force that causes intelligent, well-meaning teams to take on more risk, ignore warning signs, and rationalize catastrophic choices.
From the Bay of Pigs invasion to the Challenger disaster to the Boeing 737 Max, groupthink has left a trail of preventable failures throughout history. Dr. Hall explains the behavioral science behind why this keeps happening and more importantly, how leaders can break the pattern before it costs them.
Whether you're leading a team of two or two hundred, this episode will change how you run your next meeting.
