In this sparkling and provocative new book, renowned neuroscientist David Eagleman navigates the depths of the subconscious brain to illuminate surprising mysteries: Why can your foot move halfway to the brake pedal before you become consciously aware of danger ahead? Why do you notice when your name is mentioned in a conversation that you didn't think you were listening to? Why are people whose name begins with J more likely to marry other people whose name begins with J? Why is it so difficult to keep a secret? And how is it possible to get angry at yourself: who, exactly, is mad at whom? Taking in brain damage, plane spotting, dating, drugs, beauty, infidelity, synaesthesia, criminal law, artificial intelligence and visual illusions, Incognito is a thrilling subsurface exploration of the mind and all its contradictions.
