Professor Eric Anderson to Tyrese and Rev Run: Men Are Designed to Cheat

Are men biologically wired to be unfaithful? Professor Eric Anderson joins Tyrese and Rev Run to weigh in on this potentially uncomfortable topic.

"Absolutely, without a shadow of doubt," Dr. Anderson says as Rev Run reacts in shocked disbelief. "Men are endocrinologically designed to cheat."

In his provocative book The Monogamy Gap, Dr. Anderson interviewed men who strayed despite being in serious relationships. His research convinced him that there is a gap between what men really desire and what is allowed by perceived moral constraints.

Find out why the professor says, "Monogamy is not the normal expectation." And, keep watching as things get even more heated between him and Rev when he reveals that he doesn't believe in God.
