On Being Tumblr

On Being with Krista Tippett is a public radio project delving into the human side of news stories + issues. Curated + edited by senior editor Trent Gilliss.

We publish guest contributions. We edit long; we scrapbook. We do big ideas + deep meaning. We answer questions.

We've even won a couple of Webbys + a Peabody Award.
Using social media produces a solid, double-digit increase in oxytocin.

Paul Zak, author of Moral Markets: The Critical Role of Values in the Economy, says people who release more oxytocin tend to be happier.

We actually interviewed the professor of economics for our show "The Science of Trust" a couple of years ago. It’s well worth a listen.

Paul Zak and the Neurology of Neighborly Exchange

Earlier this summer, I spent more money than I wanted to on camping equipment — hiking poles and other gear I won’t likely use off the trail. Maybe I should have asked a neighbor to borrow or rent their stuff instead. Not only would I have saved some dollar bills, but my brain might have gotten a neurological boost as well.

That’s according to neuroeconomist Paul Zak, who was recently quoted in The New York Times about the benefits of participating in neighborly economic transactions — for example, renting a pricey Roomba from someone down the street rather than buying one from a big box store. According to Zak:

"There is an underlying notion that if I rent my things in my house, I get to meet my neighbor, and if I’m walking the goods over, I get to meet them in person … We’re drawing on a desire in a fast-paced world to still have real connections to a community."

Krista interviewed Zak for "The Science of Trust: Economics and Virtue," a show we produced in 2009 as the Great Recession was unfolding. He does research on oxytocin, a powerful neurotransmitter known as “the trust hormone” that’s commonly associated with breast feeding and childbirth but is also triggered by other forms of social bonding.

Zak’s work around trust and transactions reminds me of a different story altogether from Khalid Kamau, who was featured in our Repossessing Virtue series on the economic crisis. Kamau’s reflection about borrowing eggs and milk from a neighbor hints at a collective longing to belong to a supportive social fabric.

All of this has me wondering how and whether these trends might be playing out in your own life. Are you sharing or in some way participating in neighborly exchanges of goods and services? If so, have you experienced a greater sense of belonging or social connection as a result? Share your oxytocin story with us.

My Oxytocin Moment

Colleen Scheck, Producer

Our immersion into the world of neuroscience for this week’s program with Paul Zak has given me a label for one of the uplifting parts of my weekdays — my “oxytocin moment.” It’s the moment I exit work to pick up my 7-month-old son. Walking to the car, a rush of energy, excitement, and warmth comes over me as I eagerly anticipate how his smile widens when he recognizes me, and the giggle that bubbles up when I hug him and tickle him under the chin. I can’t get to him fast enough, and I’m certain one day a fender-bender will be the result of my mad dash to exit work and pick him up.

So now I interpret that rush to be a surge of oxytocin in my brain. The hormone has long been known for its role in childbirth and the mother/child bonding process that I acutely experience these days. But as Zak’s research is showing, it has other profound influences on broader social behavior, including our ability to trust. Since my brain fails to fire the neurons needed to comprehend neuroscience, I went looking for easily digestible descriptions of his work, and found a few helpful things.

His article, "The Neurobiology of Trust," in the June 2008 issue of Scientific American is a helpful overview, with simple visuals, of how he became interested in oxytocin’s relation to trust, how his experiment — the “Trust Game” — was conducted and its findings, and some of the implications of his research. Besides its impact on the field of economics, I’ll be curious to see if future insights emerge about oxytocin’s relationship to neurological disorders like schizophrenia or maladies such as social anxiety.

Also helpful, and fun, was a 2005 television segment from the Australian Broadcasting Company science program Catalyst. The reporter participates in Zak’s trust game as well as a related experiment using MRI imaging of his brain. He talks to Zak and other scientists about the biology of trust, from primates to humans.

And, given my current life status as a new mom, I enjoyed stumbling upon Hug the Monkey, a blog about the latest research and issues around oxytocin’s best-known function by science and technical writer Susan Kuchinskas.
