Same, my mother absolutely believes it, so much so that she refuses to do it for family and friends because she doesn't want to see anything bad with anyone she knows.

Same with reiki, she tried it on me once and asked if I felt anything, which I obviously didn't so I said as much and her reply was "oh, well that's probably because you don't believe in it."

I love you mom, but that's called a placebo.

There's a very surprising percentage of people who believe more or less in astrology, numerology and other predictive bullshitology. Even in developed countries with a good level of education.

I mean, sure some people believe it, but to be successful at it, you have to engage in the grift. Because it doesn't actually work. You have to massage the story to get people hooked and make them think you're telling them something valuable. Reading tarot cards for fun isn't the same as building a business around your psychic abilities.

It's the difference between playing with a Ouija board and telling the police that a victim has contacted you from beyond the grave for the reward money. Belief in the former can be sincere, but you don't do the second part unless you know it's a con.
