What is a Mentalist and What Do They Do?
Mentalists are like mind readers. They appear psychic by using "highly developed mental or intuitive abilities."

Most modern mentalists use misdirection, mathematics, psychology, and general trickery to leave their audiences spellbound.
What's the difference between a mentalist and a mind reader?
Psychics often present their power as spiritual or supernatural. Not all psychics are intentionally misleading their audiences. Some psychics are drinking their own Kool-Aide. To be clear, there is no evidence that real psychics exist.
Both mentalists and mind readers claim abilities that they don't possess.
There is nothing wrong with going to a psychic or mentalist. Much like seeing theatre, suspend your disbelief and enter with a sense of wonder.
