New Scientist has an article about researchers trying to understand why people often cooperate and do good things, for no self-serving reason they can find. Previously the prevalent theory has been that people do it for their own self-interest, but various experiments show otherwise. Hahah, surprise. People might be good for no good reason.
Over the past decade, experiments devised by Ernst Fehr of the University of Zurich in Switzerland, among others, have shown that many people will cooperate with others even when it is absolutely clear they have nothing to gain. A capacity for true altruism seems to be a part of human nature. It is a heartening discovery, yet one that has also touched off a firestorm of debate.

The experiments at the centre of the controversy are as simple as they are illuminating. They ignore theory-based preconceptions about how individuals ought to behave and focus instead on finding out what they actually do when playing games in which there is real money at stake.

One of the most basic of these games is the "ultimatum game". An experimenter gives one of two players some cash, say $20, and asks that person, called the "proposer", to offer a fraction of it to the second player, called the "receiver", whose identity is hidden from the other player. The proposer can offer any amount they choose, from nothing up to the entire $20. The receiver then has the choice of accepting or rejecting the offer. If he or she accepts, the cash is shared according to the original offer. A rejection means that no one gets anything. The game is played just once.

For the receiver, self-interest would seem to dictate accepting the offer no matter how small it is, since getting something is better than getting nothing. Knowing this, a similarly self-interested proposer should offer as little as possible. But over the past decade or so, research on student volunteers has shown that proposers in such experiments typically offer anything from 25 to 50 per cent, while receivers tend to reject offers of less than 25 per cent.

"People reject low offers," says anthropologist Joseph Henrich of Emory University in Atlanta, Georgia, "because they view them as unfair." And through their rejection, they show a willingness to punish the unfair offers even at a cost to themselves.

A vast number of other experiments illustrate the same point. Last year, for example, Fehr and his colleagues had students play a version of the famous prisoner's dilemma game, in which two people can prosper through cooperation but are also given strong incentives to cheat on one another. In this game, if the participants cooperate, each receives a worthwhile monetary pay-off. But either player can get an even higher pay-off by cheating while their opponent cooperates (see Diagram).

In this particular version of the game, the researchers got people to play sequentially: one would go and then the other, fully aware of what the first had done. In theory, anyone thinking only of their own personal gain would always cheat, as this pays more than cooperating. But in the experiments, although many of players who went first did cheat, others cooperated, despite knowing that the second player could sucker them by cheating. What's more, roughly half those who went second rewarded cooperation by treating their opponent fairly, even though that meant forgoing an easy pay-off for themselves (Human Nature, vol 13, p 1). "The facts are clear," Fehr says. "Many people are willing to cooperate and to punish those who don't, even when no gain is possible."
"Many people will cooperate, and punish those who don't, even when no gain is possible"

This tendency - which researchers call "strong reciprocity" - throws into question the assumption that apparently selfless behaviour must have some selfish explanation. Across disciplines, researchers now agree that people often act against their own self-interest. "This is the most important empirical work on the human sense of justice in many years," says evolutionary biologist Robert Trivers of Rutgers University in New Jersey.
Well, there's hope for humanity. I don't find their findings in any way surprising. It doesn't either have the be an either-or proposition whether it is enlightened self-interest or not. It all depends on how big you feel your operating sphere is. Cooperation and justice is good for humanity. And I'm a whole lot more than a bag of skin. So, sure, it is in my own self-interest to promote good will, justice and cooperation, even with people I'll never see again, and even when nobody's looking.

..who claim that altruism is a part of our nature and that negative selfish attitudes can be transformed into love & caring for our world family.
It is hopeful, thanks, Ming.  

23 Mar 2005 @ 15:29 by Quirkeboy @ : Not so sure..
That this proves altruism exists.. although I believe it does.
The second experiment isnt fleshed out so I wont comment on that..
But in the first experiment.. if I am following my own self interests.. and I was the proposer.. I would have to determine how much I should offer the receiver to ensure I receive something.
If I offer 50% the reciever would realize I was being fair and accept the offer for sure... and I would get $10.
But I could be greedy and gamble that he will accept 25% because the reciever may accept SOMETHING instead of nothing... and I get $15.
Either way Im taking into consideration how much it will benefit me.. how is this showing altruism? How many proposers offer the full %100? How many receivers reject offers because it seems unfair to take TOO much?
This seems to be a akin to a member of the mafia trying to gauge how much to bribe a cop.. if you dont offer him enough you will get thrown in jail and get nothing..
This seems to be an exercise in bribery and revenge.
I do believe altruism exists.. but this experiment seems to prove the opposite.

BULLY Personality is NOT INTRINSIC/NATURAL but an expression of a SOUL in DIS-ease!
I'm not going into reasos why that is so....it's been so "forever" and those with the disease have through History taken over the Social "game"/Human Co-operation meme and thrown it for a loop through a million ways DECEPTION,BRAINDWASH,PLAIN OL'CRUELTY DIS-INFO, MIS-INFO, ReligionS (PLURAL), "Science", you name it....TO UN-DO our NATURAL WAY OF BEING!!! IT HAS TAKEN ALL THE SHIT WE STILL TO THIS DAY SEE OUR "GOV'S PUTTING OUT THERE!!! TO HURT US; KEEP US DOWN, ONE MORE YEAR, HOPEFULLY... THEY; The Kings and Queens, be they presidents, emperors, dictators -or whatever...- ARE -FINALLY- FORCED TO COUNT their time in months, soon in only weeks > days! THAT IS HOW NATURAL AND STRONG our NATRUAL TENDENCY of SYMBIOSIS and CO-OPERATION IS!!!!....IT HAS TAKEN ALL THAT DECEPTION & INTIMIDATION/MURDER and other CRAPP to keep people down, away from expressing their natural tendency; the one which these surpriced 'scientists' came face to face with!

THANKS, Ming!... So great that you posted this article!... It will have much greater impact on Socio-Cosmic level than any of us can even guess.
The Pic is just DARLIN'!!!... : )  

23 Nov 2009 @ 09:27 by drew3000 @ : a lot of things at play here
Doing good things for others is often essential for self respect and healthy self respect is a positive attribute for gaining respect from others, which does increase resources in a community, so I think some links could be made. Halthy self respect could be seen as a trait that has survived the ages, so the trait for generosity would pass along as well.
