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.

Adam explains how the idealized lawn is an unnatural monstrosity, and that the design of the suburbs is slowly killing you. Plus, the racist history of suburban planning led to today's institutionalized segregation in schools.
