Until recent decades, the unconscious mind remained a mystery. Psychologists argued over whether it existed, and if it did, was it our ally or our enemy? With over 30 years of revolutionary research into the unconscious mind, Dr. John Bargh’s accessible debut BEFORE YOU KNOW IT takes us on an engaging and enlightening tour of the forces that affect everyday behavior while transforming our understanding of ourselves.


With surprising and entertaining revelations, tricks to help you remember your to-do list, shop smarter, and sleep better, Dr. Bargh will help you harness the power of the unconscious mind to improve your life. He reveals the pervasive influence of the unconscious mind in who we choose to date or vote for, what we buy, where we live, how we perform on tests and in job interviews, and much more. Before You Know It will profoundly change the way you understand yourself by introducing you to a fascinating world only recently discovered, the world that exists below the surface of your awareness and yet is the key to unlocking new ways of thinking, feeling, and behaving.
