Is Derren Brown a genius

Derren Brown is a psychological illusionist who uses psychology, illusion, magic, showmanship and suggestion. All of these arts are difficult to learn. Since Derren is skilled in all of them, yes, I would say he's a genius.

He can also predict things about people just by analysing them. He can make people believe things that never happened. He can even hypnotise people such as making them unable to move from a spot.

Derren can also predict how many letters are in a random paragraph after having that paragraph read to him and so much more.

I would certainly say he is a genius.
