Do lie detector tests actually work?

Is it possible to objectively know when someone is lying? Humans have wrestled with this problem for centuries. And about 100 years ago, the polygraph device was made to solve it. But can this machine, commonly known as a lie detector, actually do what it says? This week, we dive into the controversial history of the polygraph to find out how it works, why Pete Hegseth is using it to hunt Pentagon leakers, and how the government has allegedly punished people for selling tips to "beat" the machine, all while the device remains banned from most courtrooms. Our guests this week helped us cover this one from all angles: Amit Katwala, author of Tremors in the Blood Murder: Obsession, and the Birth of the Lie Detector George Maschke, former U.S. Army interrogator and reserve intelligence officer and co-founder of AntiPolygraph.org Nathan Gordon, Director of The Academy for Scientific Investigative Training, President of the International Society of Polygraph Examiners Have a question or argument you want us to tackle?
