What's the Difference Between the Right and the Left?

Am is a new book by am jonathan hiht. It's about how our brains can rationalize our own behaviour in ways that we aren't even aware of. The author also explores the concept of 'the press secretary' and its role in explaining our actions to others. He says it could help us understand why we feel disgusted at other people having sex with each other, even if it's purely consential.
