 So David says that when you use spoken language and you do production, human speakers subconsciously produce hidden messages that give insights into their innermost thoughts when you play them in reverse. And Oates applies this theory to various fields such as psychotherapy, criminology, and business negotiations. So he's been on this program since the very beginning. Like I said, it's been nearly 30 years or more since he's been doing this type of revelation, giving us information with reverse speech. So David, welcome to Ground Zero.
