William CooperWilliam Cooper was born in Baltimore in 1967. Ever since he was a child, William had a passion for mental tricks and persuasion techniques. He got it from his father, who was an illusionist magician. His interest in psychology grew even more when he as 16 years old, after receiving a book on how to interpret body language written by Paul Ekman. And that book cemented his path in pursuing a career in psychology. At the age of 18, William began studying Psychology at university. At the age of 20, he attended several seminars hosted by Richard Bandler, co-developer of NLP. At the age of 24, William enrolled in a training seminar on the psychology of persuasion held by Dr. Robert Cialdini, the world's leading expert in the science of persuasion. Since then, he has dedicated his life to studying and researching human behavior and understanding the scientific principles underlying the psychological mechanism of how and why you end up saying YES! Today, William Cooper is one of the leading experts in the science of persuasion, mental manipulation, and marketing applied to sales. He has written several books on dark psychology, and (unconventional) emotional manipulation techniques, on an empath, and how to analyze people. With his books, William wants to teach others the ethical and constructive use of persuasion techniques and help people learn to defend themselves against mental and emotional manipulation to avoid becoming prey to others.
