altruism to attract a mate

[kc8tbe]

The Economist has an article on how humans use altruism as a form of "conspicuous consumption" to attract mates, but how different sexes apparently go about this differently.

Altruism, according to the text books, has two forms. One is known technically as kin selection, and familiarly as nepotism. This spreads an individual's genes collaterally, rather than directly, but is otherwise similar to his helping his own offspring. The second form is reciprocal altruism, or “you scratch my back and I'll scratch yours”. It relies on trust, and a good memory for favours given and received, but is otherwise not much different from simultaneous collaboration (such as a wolf pack hunting) in that the benefit exceeds the cost for all parties involved.

Humans, however, show a third sort of altruism—one that has no obvious pay-off. This is altruism towards strangers, for example, charity. That may enhance reputation. But how does an enhanced reputation weigh in the Darwinian balance?

To investigate this question, the researchers made an interesting link. At first sight, helping charities looks to be at the opposite end of the selfishness spectrum from conspicuous consumption. Yet they have something in common: both involve the profligate deployment of resources.

That is characteristic of the consequences of sexual selection. An individual shows he (or she) has resources to burn—whether those are biochemical reserves, time or, in the human instance, money—by using them to make costly signals. That demonstrates underlying fitness of the sort favoured by evolution. Viewed this way, both conspicuous consumption and what the researchers call “blatant benevolence” are costly signals. And since they are behaviours rather than structures, and thus controlled by the brain, they may be part of the mating mind.

There is, of course, a lot of evidence for the first part of this conjecture. Everybody knows that fast cars attract fast women. The second, though, may come as a surprise. So the team did an experiment to compare them.

They divided a bunch of volunteers into two groups. Those in one were put into what the researchers hoped would be a “romantic mindset” by being shown pictures of attractive members of the opposite sex. They were each asked to write a description of a perfect date with one of these people. The unlucky members of the other group were shown pictures of buildings and told to write about the weather.
The participants were then asked two things. The first was to imagine they had $5,000 in the bank. They could spend part or all of it on various luxury items such as a new car, a dinner party at a restaurant or a holiday in Europe. They were also asked what fraction of a hypothetical 60 hours of leisure time during the course of a month they would devote to volunteer work.

The results were just what the researchers hoped for. In the romantically primed group, the men went wild with the Monopoly money. Conversely, the women volunteered their lives away. Those women continued, however, to be skinflints, and the men remained callously indifferent to those less fortunate than themselves. Meanwhile, in the other group there was little inclination either to profligate spending or to good works. Based on this result, it looks as though the sexes do, indeed, have different strategies for showing off. Moreover, they do not waste their resources by behaving like that all the time. Only when it counts sexually are men profligate and women helpful.

That result was confirmed by the second experiment which, instead of looking at the amount of spending and volunteering, looked at how conspicuous it was. After all, there is little point in producing a costly signal if no one sees it.

As predicted, romantically primed men wanted to buy items that they could wear or drive, rather than things to be kept at home. Their motive, therefore, was not mere acquisitiveness. Similarly, romantically primed women volunteered for activities such as working in a shelter for the homeless, rather than spending an afternoon alone picking up rubbish in a park. For both sexes, however, those in an unromantic mood were indifferent to the public visibility of their choices.

These two studies support the idea, familiar from everyday life, that what women want in a partner is material support while men require self-sacrifice. Conspicuous consumption allows men to demonstrate the former. Blatant benevolence allows women to demonstrate the latter. There is, however, a confounding observation. The most blatant benevolence of all, that of billionaires giving away their fortunes and heroes giving away (or at least risking) their lives, is almost entirely a male phenomenon.

To examine this, the team did another experiment. They found that when requests for benevolence were financial, rather than time-consuming, romantically primed men were happy to chip in extravagantly. Giving money to charity is thus more akin to conspicuous consumption than it is to blatant benevolence. The primed men were also willing (or at least said they were willing) to act heroically as well as spend—but only if the action suggested was life-threatening. Women, romantically primed or not, weren't.

Heroism, of course, is a pretty high-risk strategy. But if you survive, you really have proved the quality of your genes. As the old saw has it, faint heart never won fair lady. On the other hand a soft heart, it appears, wins a gentleman.

It benifits an indivual's chance of survival and propagation to be in a fuctional sucessful group. I would Recomend Richard Dawkins' Nice Guys finnish first if you are interested on the subject.

Lately, just by coincidence really I've found myself working part-time jobs for two charitable organizations over the past year.

One of the jobs involved calling up people associated with the organization and asking if they'd like to donate money to it.

The other job involved calling up people and asking if they would be willing to go door to door to raise money for our organization.

Off hand, in the first job, I'm not too sure if their was a very dramatic difference between the number of males willing to donate money and the number of females. I think that I probably got slightly more males donating then females but I doubt it was overly significant.

Where there's a HUGE difference though is in my second job asking if the prospect is interested in going door to door. Both myself and the charity as a whole gets many, many more females willing to volunteer to go door to door then males. Almost to the point where if I got a male on the phone I almost wished I could just hang up because I knew they hardly ever volunteered.

Maybe part of it though was that the calls typically took place during the day and so I would reach far more women then men as more women tend to be home during the day. However maybe their's just something else to be said for alot of men having a more negative opinion then women on asking others for money.

Of course this is all just personal experience.

I know it's just a personal observation, but guys on dates tip better than guys who are just out with their friends.
