Haha yeah I used to be always told that when I was a kid.
People believe in my country that if you
grind up the dessicated body of a hummingbird and the girl pees on it, she'll fall in love with you.
Same as all the crap that gets sold today. Some scammer, recognizing the inherent gullibility or natural cognitive biases of people invents a product or service or story, claims expertise and success, and gains some combination of wealth, power, and fame.
For example Gwyneth Paltrow makes bank by selling all kinds of crap on her Goop website.
Humans are easy to fool because our brains don't work the way we think they do and other humans exploit that for their own gain. Some, like Penn and Teller, do it honestly for entertainment, others, like Sylvia Browne, do it dishonestly by claiming powers they don't have.
