`John Bargh's Before You Know It moves our understanding of the mysteries of human behaviour one giant step forward. A brilliant and convincing book.' - Malcolm Gladwell, author of Blink and David and Goliath

How much of what we say, feel and do is under our conscious control? How much is not? And most crucial of all: if we understood how our unconscious worked - if we knew why we do what we do - could we finally, fundamentally, know ourselves?

From checking a dating app to holding a cup of coffee or choosing who to vote for, our unconscious secretly governs everything we feel, think and do. In Before You Know It, Dr John Bargh - the world's leading expert on the unconscious mind - reveals the psychological forces that are at work behind the scenes as we go about our daily lives, and offers simple steps to improve your sleep, boost your memory and live better.
