Emily Ruins Adam

This week, Adam's world gets turned on its head when his friend Emily takes over to "ruin" him, pointing out where a few of his facts fall short. She debunks the idea that IQ tests measure intelligence and reveals their racist history, then does a rapid fire battle against information that Adam has gotten wrong in previous episodes. Plus, she explains the "backfire effect," and why proving someone wrong, even with hard evidence, won't necessarily convince them to change their mind.
