Professor Steven Pinker has spent his life thinking about thinking. Now he wants us to join him. For this series Professor Pinker has created a critical thinking toolkit which he hopes will help all of us make better decisions about – well, everything. Steven will be joined by some big thinkers, and people who have to deal with the consequences of irrationality, as he sets out to steer us away from common fallacies and logical traps set by our own animal brains.
