One Good Deed Deserves Another

In the early 60s, Robert Axelrod was a math major messing around with refrigerator-sized computers. Then a dramatic global crisis made him wonder about the space between a rock and a hard place, and whether being good may be a good strategy. With help from Andrew Zolli and Steve Strogatz, we tackle the prisoner’s dilemma, a classic thought experiment, and learn about a simple strategy to navigate the waters of cooperation and betrayal. Then Axelrod, along with Stanley Weintraub, takes us back to the trenches of World War I, to the winter of 1914, and an unlikely Christmas party along the Western Front.

I've have been a member of the Baha'i Faith (one God, One Religion, one Mankind) for over 30 years, most of it spent as an isolated believer wondering if my participation was of consequence. I was encouraged by the comment concerning computer tit-for-tat that if a 10% initial response was cooperative eventually the outcome may become collaborative - a hopeful sign for humankind. How do I obtain a transcription of program? Thanks.

We use Prof. Axelrod's research to illustrate the value of collaboration in outsourcing relationships. It helps break down traditional win-lose thinking by showing procurement professionals that it's smarter to collaborate. We've discussed this at and built a practice called to show companies how to implement collaboration successfully.

Listening to the segment of the Christmas truce and its aftermath moved me to tears, even though I had heard this story before. It's astounding to think that a few nice people can alter the game plan. Every year I spend a week or two in Fairfield, Iowa, practicing the Transcendental Meditation and TM-Sidhi program in a group of 2,000 or so. The effects have been measured by independent sociologists who have found a wide range of beneficial results, from lowered crime rates, war deaths, accident rates and absence of major hurricanes from US shores during this time. This is explained as being similar to the Meissner effect in superconductors: the square root of one per cent of a population practising Transcendental Meditation and the TM-Sidhi Programme, morning and evening together in one place, is sufficient to neutralize negative tendencies and promote positive trends throughout the whole population. More about this here:

Axelrod says if you play nice around 10% of the time you will change the effect of the game, but there's still a chance that the opponent will retaliate. What would happen with a large enough group creating a coherent field and playing this game? Possibly that the thought of hostile action on the part of the opponent would never even arise. I'd love to see a segment that explores this...thanks for all your great programs. Best wishes, D. Sosin

Today's episode began with a striking quote about the violence of nature... I'd like to see it in written. Could someone post it? Thanks, Julia

An elegant and entertaining explanation of the logic of cooperation and societal cohesion.

I enjoyed your program exploring the "Prisoner's Dilemma." Here's a version that I adapted for use in the classroom. A great tool to explore decision-making and communications.

When you help your friends and others close to you (people in your ethnic group, culture, whatever), you also indirectly help spread your genes as those individuals are more likely to care for your relatives. It seems to come naturally and doesn't have to be judged as either right or wrong.

And what about the altruistic behavior we see when people are willing to donate their money and or time to help people hit by a natural disaster in another country? Or the sacrifice soldiers make to fight for their country?

I really appreciate the show and the podcasts. But I'd just like to point out one problem I have. I understand that you need a bit of cash to support the costs of keeping the site up; hence the support of Pro-Flowers. Can I just point out that when ExxonMobile supports NOVA, they don't stop several times in the middle of the show to promote a Gas sale. . .

What song closes out the show? I really liked it, but have no idea what it is.
