Over the past two decades researchers have developed remarkable new tools for probing the unconscious, or subliminal, workings of the mind. Employing his trademark lucid, accessible explanations of the most obscure scientific subjects, Leonard Mlodinow unravels the complexities of the subliminal mind and reveals its influence on how we misperceive our relationships with family, friends, and business associates, misunderstand the reasons for our investment decisions, and misremember important events. In the process, he changes our view of ourselves and the world around us.
