Most of us think we’re good at detecting lies, but it turns out humans only get it right about half the time. And why do we do it anyway? What makes us want to deceive other people? In this episode we get to the truth about lying. We take a look at when people start lying, and how that helps us in our development as humans. We also hear from A. Lie, who tries to remind us that we might need lies more than we think. Plus, Angela Evans stops by and fills us in on the latest lie detection research. And remember to listen for the Moment of Um at the end of the show. This time we get squishy and find out if sponges are still harvested from the sea.
