This is the fifth edition of coffee chats, so I wanted to switch it up a little bit, and bring you a really fascinating look into polygraph tests. What are they? How do they work? What does it ACTUALLY mean for someone to pass or fail a polygraph? All of these are good questions, and we're answering all of them in this episode. From the invention of the polygraph, to how it has set standards in US courts, to the implications that it can have in criminal cases. This was a really interesting episode to put together, so grab yourself a coffee, and let's chat!
