Rick discusses his Complex PTSD diagnosis, and how, as a result, he’s decided to live life as he has never lived it before: openly and vulnerably.

What is truth? How has it evolved? And what is its impact anyway? Evolutionary science shows that subtle social manipulation of fellow group members was a key driver of intelligence in the human lineage. And even animals use trickery to their advantage. Big Ideas looks at why we lie and why deception is so widespread in modern public discourse.
