In his book, "Tricks of the Mind", Derren Brown writes:
"I am often dishonest in my techniques, but always honest about my dishonesty .
As I say in each show, I mix magic, suggestion, psychology, misdirection and showmanship. I happily admit cheating, as it is all part of the game. I hope some of the fun for the viewer comes from not knowing what is real and what is not. I am an entertainer first and foremost, and I am careful not to cross any moral line that would take me into manipulating people's real-life decisions or belief system".
