Famed magician Jamy Ian Swiss sits down with D.J. Grothe to talk about psychics. As an advisor to the James Randi Educational Foundation, Swiss helped put self-proclaimed psychics to the test on ABC's "Primetime Nightline".
He discusses the phenomenon of celebrity psychics and why their claims should be challenged. But are all psychics knowing charlatans? Swiss says no, but even the self-deluded have the capacity to do harm to an unknowing public.
