Michael Shermer Tests the Polygraph and Lie Detection

From YouTube:

Can the polygraph machine really scientifically measure if someone is lying, or are all those graphs and numbers just pseudoscience in the service of law enforcement? Can we tell if someone is lying to us by their body language or facial expressions? Michael Shermer puts both the polygraph and lie detection to the test in this dramatic episode that features O.J.’s jury consultant lie detection expert.

Part two can be found here.
