Percentage of Americans: N/A
Who believes it: A small minority of surprisingly rational people

Nowadays it seems that nearly every celebrity is alleged to be a member of the secret society, the Illuminati. Celebrities including Beyoncé, Jay Z, Rhianna, and Kanye West have all been accused of being a part of the occult society and blamed for brain-washing the public with Illuminati-related imagery. While there is this creepy video of LeBron James making Illuminati symbols, the whole conspiracy is too, too ridiculous to believe. Even the Pope has been believed to be a part of the clan, so at this point who knows; you might even be a part of the Illuminati. #trustnoone
