David Green

David Green was born in Sacramento in 1955. Since childhood David 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 was 14, 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. David 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, David Green is one of the foremost experts in the science of persuasion, mind manipulation and marketing applied to sales. He has written several books on dark psychology and (unconventional) emotional manipulation techniques and how to analyze people.

With his books, David wants to teach others the ethical and constructive use of persuasion techniques and help people learn to defend themselves from mental and emotional manipulation to avoid becoming the prey of others.
