We leave cloning to scientists, and the news on experiments to science journalists. You could say we take it all on faith. In this hour of To the Best of Our Knowledge, how much trust should we put in science? Also, the science police go on a witch hunt -- the case of Nobel award winner David Baltimore. And Sybil, a fraud with 16 personalities.

Daniel Kevles is a historian at Caltech and the author of "The Baltimore Case: A Trial of Politics, Science, and Character." Kevles tells Judith Strasser about the infamous trial resulting from accusations of fraud against Nobel laureate David Baltimore and Thereza Imaishi-Kari. They were vindicated but not until after NIH fraudbusters, Congress, the Secret Service and the media enjoyed a protracted witch-hunt.

Remember Sybil and her 16 personalities? Her story became a best-selling book and a movie, and started a stampede of people claiming to have multiple personality disorder. Robert Rieber, a psychologist at John Jay College of Criminal Justice in New York, has discovered taped conversation between Sybil's therapist and the author of "Sybil" that prove the multiple personalities were fake, and that Sybil's symptoms were suggested to her. Rieber tells Jim Fleming what Sybil's diagnosis should have been, and how multiple personality disorder became a widely accepted phenomenon. Also, Robert McCoy collects quackery. He's the founder and curator of the Museum of Questionable Medical Devices in Minneapolis. McCoy tells Jim Fleming about some of his favorite items.
