Polygraph testing as a means to quantify evidence, suspicious and to assist in clarifying disputes and allegations in criminal, personal and corporate matters is prevalent in various industries and spaces in the country. Today we interrogate what lie detector tests are, how they work, which aspects of our mind, and body inform polygraph testing. We also take this conversation further by looking into whether the use of polygraph testing in the workplace is efficient to creating a good working environment. Polygraph Instructor and Director at the SA Polygraph Academy Clifton Coetzee joins Lerato Mbele for the conversation.
