What if a quiz show could fix America's political divide? Amanda talks with Harvard psychologist Joshua Greene about the neuroscience behind moral decision-making, why people don't donate to the charities that do the most good even when they want to, and how a simple cooperative quiz game is measurably reducing animosity between Republicans and Democrats.

Amanda and Joshua also dig into effective altruism without the guilt trip, why dialogue alone often fails to bridge divides, and Joshua's own surprising evolution on religion and meditation.

Added bonus: Listeners can try Joshua's donation-matching platform at givingmultiplier.org/knox to give to a cause you love (Amanda's is The Innocence Center) and a highly effective charity at the same time, with bonus matching funds for Hard Knox listeners.
