The Drive For Altruism Is Hardwired

Posted by kdawson on Tue May 29, 2007 01:47 PM
from the good-feels-good dept.
Dekortage writes "The Washington Post is reporting on recent neuroscience research indicating that the brain is pre-wired to enjoy altruism — placing the interests of others ahead of one's own. In studies, '[G]enerosity activated a primitive part of the brain that usually lights up in response to food or sex... Altruism, the experiment suggested, was not a superior moral faculty that suppresses basic selfish urges but rather was basic to the brain, hard-wired and pleasurable.' Such research 'has opened up a new window on what it means to be good,' although many philosophers over recorded history have suggested similar things."

      If we didn't get something out of giving, we wouldn't do it.
      I can say without cynicism that if I didn't get incredible joy out of caring for my infant son (who is teething, very expressive about it, and quick as a ninja monkey) I don't know that any force on earth could make me change a dirty diaper- yet somehow it's strangely enjoyable and I come back for more.

      It's pretty obvious if you think about it that we get a LOT out of contributing to others. My most-satisfying jobs have all been ones where I helped people out, my least-satisfying ones have been the ones where I couldn't tell that I was making any difference for anybody. I once put together a program to teach at-risk teens how to kayak, and when I told people what I was doing and asked for their help, they thanked me for creating the opportunity to donate gear, time, money and expertise. My experience asking for help to put the program together was quite surprising- I had thought it would be hard, they wouldn't want to, but it was the opposite: people are hungry for any chance to help others.

      If you look broadly, people are willing to die in order to make a difference. People join the army in time of war to serve. They strap bombs to themselves and blow themselves up in a crowded market, in order to serve. People will open their checkbooks and donate money, they'll give blood, they'll use their vacations to go build houses for people- there's not much people won't do for the chance to make a difference for others.

            I have heard this statistic many times and tend to believe it, within reason. The import thing to remember about it is that this also includes contributions to some organizations that you are a member of, most importantly your church. My bet is that if you look at donations to your own church as something other than "charity", then this statistic may swing the other way.

            Another way of looking at this might be that "Religious Conservatives" spend a lot more money (primarily) improving the well-being of those they consider to be part of their own group, while "Secular Liberals" contribute a smaller amount to people outside of their own group. Both seem like perfectly natural responses.

            Also remember that many religions have the concept of a semi-inforced tithe, and many European countries have gone so far as to make this a part of tax law. That sort of thing is going to skew the statics to almost meaninglessness.

                Germany and Austria are both examples of countries that have near-manitory taxes based on what religion you are a member of. The taxes are collected based on a percentage of your income, and go to the religious organization that you are registered as a member. You can register yourself as being non-religious and then pay nothing, but you will be officially excommunicated from your church.

        Actually, the most selfish are those who insist on working directly with the charity -- even though an extra hour of work would provide them with the money to do far better good for the masses. Slate had an article on this late last year. Simply not donating would be rather neutral, because no party would benefit, and thus both would benefit equally. Check out the blockquote:

        This isn't some silly tautology. If these do-gooders really were motivated by the desire to do good, they would be doing something different. It would almost always be more effective to volunteer less, work overtime, and give more. A Dutch banker can pay for a lot of soup-kitchen chefs and servers with a couple of hours' worth of his salary, but that wouldn't provide the same feel-good buzz as ladling out stew himself, would it?

          Must be nice to be a Dutch banker. Here in the USA, professionals who make lots of money are salaried, meaning they could work round the clock until they died and not get paid a penny more than working 40 hours.

          Theoretically, you could get an extra job, but since working the same job for someone else would get you fired at BOTH workplaces, its much easier and better to volunteer your time and effort to a deserving organization who needs it.

          Couple that with the fact that working hard at the same or similar job all the time leads to declining health and an early demise, and volunteer work that makes you feel good about yourself and gives you a break from the daily grind starts to sound pretty great after all.

          The best option? Give some of your money AND some of your time.

      Not true:

      Or I should say, only partially true. You're saying that altruism is a selfish endeavor, meaning, giving away something is only done because the brain will reward you with pleasure. True. However, you're missing the bigger picture of this article: altruism is not just about pleasure, it's about survival.

      Take this altruistic concept back to a primitive, tribal society level. One hunter brings back a deer to the village. He can hoard it all to himself and ensure the survival of himself and/or his family, OR, he can divvy out the deer to the entire tribe even though this means he'll get less for himself. Why would he do this? According to you, it's simply because it feels good to give, but the point of this article (imho) is to show that it's actually beneficial to his survival. And his survival is 100% dependent on the survival of the tribe.

      So, yes, it is selfish, but it's selfish on a tribal/societal level. Sharing ensures the survival of the tribe, therefore sharing ensures the survival of the individual (because it's really hard, if not impossible, to survive on your own in a hostile world).

      That's my two cents.

    ...that's similar to that when you get food and/or sex from doing "good things", doesn't that possibly mean that doing good things is historically/genetically programmed into us as one common way to get more more food and sex? And if you are doing good deeds in anticipation of that "dinner and a movie," it isn't really altruistic, is it?

    If you're a Christian, is it impossible to be altruistic? If you do good deeds, don't you ingratiate yourself witht he Lord, thereby increasing your chance of being admitted to heaven? So, even if you don't really "get" anything for doing good deeds, you're still going to get a reward for it in the afterlife right? Which would mean it wasn't really altrustic.

      It is axiomatic of Christianity that we've all "earned" nothing more than death, and it's only by divine grace that we are reunited with God. The religion is not about "getting in" to an afterlife paradise for being good (though many so-called believers behave that as if it is).

      The good works are not sufficient to get a person to heaven. Getting to heaven, in the Christian mindset, requires a recognition and acceptance of God's forgiveness of offenses against God and neighbor, and responding with a selfless desire to please God and look out for our fellow humans. I suppose someone MIGHT do these things for a reward, but a growing and maturing Christian will grow beyond that in time. God also can read our minds and hearts, and when we die, he won't be using a checklist to see who gets in and who doesn't. If our hearts are in the correct state, as developed through a life's worth of experiences, then he will let that person into heaven.

      By the standard you're using, can any act ever be altruistic? Someone always receives a reward in doing good for someone else either by having pride in being a person who can choose doing something for someone else over doing nothing, or that by doing something to improve humanity in general everybody is better off including the one doing the act.

    Altruism is also observed in vampire bats, curiously, who remember who shared blood with them previously, and who did not. Altruism is a simple kind of savings scheme. When you are lucky, you share. When you are unlucky, you borrow. It depends on a good memory and a set of rules that have to be instinctive, so everyone agrees with them. (No point if everyone randomly invents "good" and "bad" behaviour.)

    Guilt, on the other hand, is waiting for the blow to fall. We don't feel guilty when there's no risk of being punished, and we don't act altruistic when there's no-one watching.

Most of the people around us were immediate or extended family. We can also assume that a group of people who are sometimes generous with each other will survive better than people who are strictly selfish. If we put those two facts together and stir it with some evolution... what do you get? People who help each other are more likely to survive as a group. So if we have two tribes, one family that has only selfish tendencies and one that has generous tendencies; the generous family is more likely to survive as a whole. There's no secret here.

    Humanity is a social animal. We form packs. We are hardwired to be pack-supporting; you see a huge natural disaster and people rush to the area to help...They don't turn and run the other way. A child gets lost in the mountains, and you get hordes of volunteers tromping around and getting themselves lost in the search.

    This is not behaviour that is smart for the individual. Risking your own life for others? Not something you see often in the animal kingdom. But it is something that occurs among humans, and it is a big part of what we consider "good".

    Philosophically, ethics falls into two distinct branches: relativism, and objectivism.

    Relativism basically states that good and evil are relative...Relative to you personally, relative to your culture, relative to your psychological state. It fits with people's differing views on what is right and wrong; I think it's right, you think it's wrong, we're both correct. Basically it's worthless. If you're a relativist, morals are meaningless, because you can only apply moral judgements to yourself, and what the hell point is there in that?

    Objectivism states that good and evil are objective...That there are things that everyone should agree are right and everyone should agree are wrong. Logically, objectivism must be correct, because the alternative is relativism, and relativism is worthless. But no one agrees about right and wrong, so how can it be right?

    But when you look at it in terms of humanity as a social animal, it becomes a little clearer. The "Robin Hood" story is a classic example: Stealing is bad, except when you're stealing from the rich and giving to the poor, right? Obviously the group that is being stolen from (the rich) still think it's bad, but since the vast majority of people are not rich, historically it's been considered good.

    Mill came up with the theory of Utilitarianism to attempt to explain this sort of thing: in a nutshell, whatever makes the majority happy is right, and whatever makes the majority unhappy is wrong. Politicians live by this one, because they never have to actually consider the greater good, they just have to make 51% happy until the next election. So adding a tax on gasoline to reduce consumption and using the money to pay for better public transit and research into cleaner energy, while probably the "right" thing to do, would never fly because it would piss off 80% of people and the guy'd get canned in the next election by someone running on a "repeal the gas tax" platform.

    So utilitarianism clearly needs some work...Reduce "good" into "happy" and you end up with nothing but bread and circuses, because that would make people happy, and happy == good. This, in a nutshell, is the problem with democracy.

    So we have a hardwired inclination toward altruism. It definitely explains a few things. The problem is, humanity has a lot of hardwiring. We have tons of instincts, reflexes, automatic responses. Most people learn to override those things as part of their day to day life. Can't live purely on instinct. So what value is it to have a piece of altrustic hardwiring in a society that preaches just the opposite? Altruism is an irrational response, from the point of view of the thing that's about to put its squishy coropreal self in harm's way.

    Still, it's nice to know that, if you're trying to be altrusitic, if you're trying to be selfless, you're instinctive responses are going to be in line with your conscious actions. Maybe everyone...most everyone...really does have some good in them, whether they like it or not.

    For one, the research doesn't show that altruism is "hardwired", despite what Shankar Vedantam writes in the Washington Post. The brain has very little "hardwired" responses, especially for such complex and abstract behavior as "altruism". There are organs, nerve bundles, and the like, and surely some consequential neural connects at all scales of influence are determined by human genetics in a very consistent behavior (eg, the 12 cranial nerves). But even those "hardwired" connections aren't well understood, nor are the possibilities that environment after conception can make them very different.

    For another, just because altruism stimulates (some of) the same brain parts that sex and good food stimulate, doesn't mean that altruism is not "higher moral behavior". If higher moral behavior didn't stimulate neurons that we feel as pleasure, then higher moral behavior wouldn't feel good. Why not? Does god hate pleasure? Must all pleasure come from doing wrong? What kind of sick, immoral person thinks like that?

    This is just another journalist copout: we're not really good, or even responsible for what we do, because "we're wired that way". It's stupid, immoral, and should feel awful. But journalists like Vedantam and their editors seem to like it.

      • I was wondering when the defense of selfishness would begin. As capitalism and the free market are based on the Selfish Actor theory, which has been proven to be inadequate even before this finding, perhaps we need to rethink our economic system. Spin it all you like, people don't act in their own rational self interest, this has been shown over and over again in hundreds of different kinds of experiments. Our system is based on the premise that they will. Therefore, our entire economic system is based on a false premise. By focusing on the selfish aspects of our behavior, it actually encourages them. People would rather be selfless, but in a selfish system, being selfless means you get taken advantage of. So people choose to be selfish because our system requires it.

        The natural world and systems such as our economy are incredibly complex. One could find evidence of almost anything if one looked at them carefully enough. People look to nature and natural systems, and for the most part, they see what they want to see. Selfish people want evidence that the world is selfish in order to justify their feelings. So they look at the world, they see selfishness, and they discount everything else.

        There is no evidence that evolution and capitalism are effective because they involve selfishness. It is equally valid to say that they are effective despite this fact, and are effective because of the inherent cooperation involved. Do cells in your body compete with each other? Do divisions of a corporation compete? No, they both cooperate, and that is why a body and a whole corporation are more effective than a cell or a corporate division: cooperation, not competition.

        But you keep on telling yourself that selfishness is natural, right, and good if that lets you sleep at night.
              • The Egyptian empire thrived for over a thousand years, in the end it fell, the Aztec empire thrived for centuries, in the end it fell, the roman empire stood for over 500 years, in the end it fell, the medieval feudal system thrived for centuries, in the end it fell, the Chinese empire thrived for over 2000 years, in the end it fell. Capitalism has been around for a mere 200 years, that is nothing to what the imperial system achieved, but in the end, it fell. only for 3% of human history has there been capitalism, just because you live in that 3% do not make the mistake of thinking that the model we follow is somehow the best one.

                If you lived in the rein of Charles II, would you have gloated over the failure of the English revolution and declared democracy to be a failure and monarchy to be the best way? If you lived in the roman empire, would you have laughed at the barbarians and their feudal system, and declared the Imperial system to be superior? empires have risen and fallen, and so have systems of government. Many billions before you have claimed that the system they lived in was the best system, the final system. There is no reason to believe that capitalism is any different. Our civilization will fall, sooner or later. 200 years of history means nothing, let alone the 60 year old events you cite, it is just a blink of an eye.

        Meanwhile, the Ayn Rand tribe would have left the sick and injured to die, reducing their tribe's size and its genetic diversity (and hence their adaptability) as well as possibly losing the benefit of those who might have recovered if cared for. This would have damaged the tribe's survival chances relative to the altruistic tribe.

      • It is co-operation. The human being is a social animal because if you don't watch each other's backs, the sabre tooth tiger will first eat the other guy and then eat you. (A simplistic example of why if we are all selfish, we will all just die out).

        NO! Watching each other's back against a threat in a pack setting IS selfish. That's the whole point. It's selfish to act in your own self interest - that's the concept's MEANING. When a threat that's bigger than you requires teamwork for you to survive (large

          What you are talking about is a reasoned decision to co-operate. That is a slow process and easily sabotaged by immediate concerns leading a tragedy of commons situation. The "altruism gene" makes co-operation a more deep seated and automatic process making survival that much more likely.
