Have you ever encountered someone who clearly knows you, but you have no idea who they are? This week, we feature a classic Hidden Brain episode about people on opposite ends of the facial recognition spectrum.

Host Malcolm Gladwell struggles with identifying faces, while producer Lucie Sullivan is exceptional at it.

You probably know someone who thinks they know more about something than they really do. But you could never be described that way . . . could you?

He'll explore why this happens, and how to close the gap between what we know and what we think we know. Hidden Brain is about to go on tour!

And we grapple with a question many people ask themselves: Is my forgetfulness a sign that something is wrong with me?

Do you feel like you control your emotions, or do your emotions control you? What scientists call "emotion regulation" turns out to be one of the most important life skills we can possess.

He explains why our feelings so often go astray, and shares insights into how to reel them back in.
