From childhood, we are told that lies are bad, but without them, human relationships would fall apart. With a wide variety of children to demonstrate key developmental stages, this program presents the story of how we all learn to read and manipulate each other’s minds. Observed behavior and classic child psychology experiments show this progression in an entertaining way, from learning the boundaries of the body and the mind, through the birth of the imagination, to the ability to lie for good as well as bad—lying as a subtle expression of human empathy.
