Richard Dawkins goes after astrology, psychics, and alternative medicine, arguing that the internet has made it easier than ever to mix real knowledge with nonsense and harder to tell them apart. The first episode, Slaves to Superstition, sits Dawkins down with illusionist Derren Brown, who walks through the cold-reading techniques and stagecraft that psychics use to fake insight into a stranger's life. Dawkins visits astrologers, dowsers, and faith healers, pressing each on what evidence, if any, backs their claims, and cuts to interviews with people who have based real decisions, medical and financial, on horoscopes and psychic hotlines. He does not stay a neutral observer: the film is built around his own case for scientific skepticism, and he says so directly to camera. Alongside the debunking, the series traces why these beliefs spread so easily now, from tabloid horoscope columns to internet forums, and treats the growth of the alternative therapy industry as the same problem playing out in medicine.
