Paul Zak on Trust, morality — and oxytocin?

From TED talks comes this video (recorded at TED Global, July 2011, in Edinburg, Scotland. Duration: 16:35) which asks the question, What drives our desire to behave morally? Neuroeconomist Paul Zak shows why he believes oxytocin (he calls it "the moral molecule") is responsible for trust, empathy and other feelings that help build a stable society.

What’s behind the human instinct to trust and to put each other’s well-being first? When you think about how much of the world works on a handshake or on holding a door open for somebody, why people cooperate is a huge question. Paul Zak researches oxytocin, a neuropeptide that affects our everyday social interactions and our ability to behave altruistically and cooperatively, applying his findings to the way we make decisions. A pioneer in a new field of study called neuroeconomics, Zak has demonstrated that oxytocin is responsible for a variety of virtuous behaviors in humans such as empathy, generosity and trust. Amazingly, he has also discovered that social networking triggers the same release of oxytocin in the brain -- meaning that e-connections are interpreted by the brain like in-person connections.

A professor at Claremont Graduate University in Southern California, Zak believes most humans are biologically wired to cooperate, but that business and economics ignore the biological foundations of human reciprocity, risking loss: when oxytocin levels are high in subjects, people’s generosity to strangers increases up to 80 percent; and countries with higher levels of trust – lower crime, better education – fare better economically.

He says: "Civilization is dependent on oxytocin. You can't live around people you don't know intimately unless you have something that says: Him I can trust, and this one I can't trust."
