I recently did an interview with CBS news Channel 2 in New York about lying and lie detection. It was about a 20 minute interview condensed down to the video segment below. Some of the most important tips I provided, which were apparently left in the editing room, was to develop rapport with the person because people will trust you and talk more if they have rapport with you. Establish a baseline of behavior...physical, physiological, vocal, verbal, etc...and note any changes in that baseline and focus follow-up questions at those points. Ask open-ended questions and really listen to the words and language used to describe the event or incident since academic research suggests that looking at language will provide you greater success at distinguishing between truthfulness and deception. Also, it is important to get the right training to know what to look for and how to conduct the interview properly, because there are many false beliefs about lying and lie detection, and if you focus on the wrong things, they will not lead you to your ultimate goal, which is the TRUTH.
