Grief Vampires - Wikipedia and more

GC Skeptics wrapped up 2019 with our first international speaker, Susan Gerbic discussing her work on guerrilla skepticism and debunking psychics.

Following a demonstration of mentalism tricks and techniques from her colleague Mark Edwards, Susan detailed her experience setting up Operation Pizza Roll, her famous sting of psychic Thomas John. She explained how psychics perform ‘hot’ and ‘cold’ reads to trick unsuspecting victims into believing in paranormal communication in both live performances and reality television.

Susan talked about her Wikipedia Skepticism project, which involves editing Wikipedia pages to make them more factual, promoting critical evaluation of supernatural scams and spreading the importance of evidence based media, and the damage that fallacious and fraudulent resources can have on social perspectives.

Finally, Susan shared a variety of ways to get involved with her sting and skepticism projects, all available on her website,
