How was Chick D'Arpino's belief system changed in the book, The Believing Brain: From Ghosts and Gods to Politics and Conspiracies—How We Construct Beliefs and Reinforce Them as Truths?

Chick D'Arpino's entire life was changed when he was contacted by an alien who delivered a message on how to save mankind. Shermer interviewed the man and was certain that there was no psychosis. The materialization of the alien visitor may have manifested from the stresses of a divorce, but it was real to D'Arpino who never stopped believing it.
