Porky Pies

Synopsis

According to a recent survey we live in a world full of lies - concluding that most people tell at least two important lies a day, a third of conversations involve some sort of deception and 60 per cent of the population have cheated on their partners at least once.

To debate this and seek out the truth about lies are Professor Richard Wiseman, who has spent a lifetime trying to discover the clues that give away deception, writer Ian Leslie, who described the search for the perfect lie detector, and columnist Michele Hanson, whose mother was only ever able to tell the truth.
