How do you know when you've studied enough to pass an exam? Should you accept the testimony of an eyewitness? How do you know when to trust a doctor's orders? The answer is self awareness. Self awareness is humans' greatest superpower. Like the conductor of an orchestra, self awareness guides the musicians of the mind - memory, creativity, intelligence and skill - to perform at their best. So why do we so often get it wrong? Drawing on his own pioneering studies, as well as cutting-edge research in computer science, psychology and evolutionary biology, Stephen Fleming shows how we can learn from this groundbreaking new science, and gain the edge in a rapidly changing world.
