Is it rational that the dead can communicate with the living and give sound advice on how they should live their lives? Or the bending of spoons using your mind alone? Is that rational? Richard Dawkins doesn’t think so, and feels it is his duty to expose those areas of belief that exist without scientific proof, yet manage to hold the nation under their spell. He will take on the world’s leading proponents in their field of expertise, meet the victims who have used them and expose the history of the movements – from the charlatans who have milked these practices to the experiments and testing that have failed to produce conclusive results.

The documentary was first broadcast on Channel 4 in the UK, styled as a loose successor to Dawkins' documentary of the previous year, The Root of All Evil?

This footage is the interview with UK mentalist and illusionist Derren Brown.
