More news on the Economist:
The magazine has recently been on a bit of a sociobiology kick with several recent unsigned articles chawing the collective ear about the biological basis of human behavior. Here's what I've found over the past year or so:
# LEADERS: Evolution

It is time to turn to Darwin to explain human behaviour

# CHRISTMAS SPECIALS: Darwinism
Why we are, as we are
As the 150th anniversary of the publication of “On The Origin of Species” approaches, the moment has come to ask how Darwin’s insights can be used profitably by policymakers

Geoffrey Carr expects scientists to provide a year of celebrations and screams

# CHRISTMAS SPECIALS: Beauty and success
To those that have, shall be given
The ugly are one of the few groups against whom it is still legal to discriminate. Unfortunately for them, there are good reasons why beauty and success go hand in hand

And there's more naturally, much of it the work, one would suspect, of the magazine's science editor Geoffrey Carr.
I'm not at all opposed to the theoretical notion that our behavior, our morals our civilization & culture are all ultimately based on biology. I'm just skeptical that biology should be the thing we're focussing on.
The Economist makes a lot of the fact that murder rates, pretty much universally, peak at the time when there is the most competition for mates--teens to twenties--and rapidly fall after that. Interesting, but what does biology bring to it?
We already were perfectly well aware of the fact that violence was a young man's game--demographic research has contributed to social policy for quite some time--how does the notion that it may have an evolutionary explanation help policy makers?* I don't think it does.
And what is the evolutionary explanation for the more remarkable number on their graph--that the murder rate among males is 30 times higher in the US than Great Britain, across all age groups?
But the strong implication of the Economist articles--that we have already arrived at a time when we cannot assume that strong differences in "outcomes" between population groups are evidence of unfairness is patently and obviously false. Just a few years ago, people were making strong arguments on behalf of Larry Summers by pointing out that it was obvious that there women were innately inferior at mathematics to men. Now it appears that that isn't the case--very egalitarian societies show little evidence of an "outcome gap" in math--we only thought we had reached a state of fairness with residual unequal outcomes. Which, frankly, was clear to anyone who looked at the situation without ideological blinders.
The bit about race in the same (Dec. 20th) article is rather bizarrely credulous. We are told that people generally register three things about a person they meet: sex, age and race.
But Dr Cosmides and Dr Tooby [two of the founding figures of the latest push to apply biology to policy] pointed out that before long-distance transport existed, only two of those would have been relevant. People of different ages and sexes would meet; people of different races would not.So, in a world "where the largest social unit is the tribe, clan or what-you-will of a few hundred people" In a world where you spend every living moment associating with pretty much the same 2-300 people, we don't recognize them all? Admittedly, we wouldn't know them all well, but we would be able to recognize them. There would be no need for a super-sensitive "lineage detector."
The two researchers argue that modern racial discrimination is an overstimulated response to what might be called an “alliance” detector in the human brain. In a world where the largest social unit is the tribe, clan or what-you-will of a few hundred people, your neighbours and your other allies will normally look a lot like you, and act similarly. However, it is known from the study of modern hunter-gatherers, and inferred from archaeological evidence about ancient ones, that neighbouring tribes are often hostile.
Though an individual might reasonably be expected to know many members of his tribe personally, he would probably not know them all. There would thus be a biological advantage in tribal branding, as it were. Potential allies would quickly identify what marked them out from others, and what marked others out from them—and, because those differences would probably be small, the detector would need to be very sensitive.
Our awareness of race--and many of our other traits--has a more complex explanation that people like Cosmides and Tooby are willing to admit. they can't all be traced back to factors in some notional "early human environment." Some have roots that go back beyond early man, and beyond primates even. And many traits have a lot more cultural input than they'd like to admit.
In short, the origins of human behavious are complex and are not the place to turn for stunning insight about what we should be doing now. In fact, biological questioning of the the origins of our behavior seems to a) give us answers we already knew about, either because that's the story biologists wanted to tell us or because we all have an inherent ability to judge ourselves; or b) give us no good answers at all, as biologists radically simplify complex phenomena in order to imply they've got the goods when they don't. They tell us they know the etiology of social phenomenon X, when they don't really appreciate X as a phenomenon at all. How can they tell us how X arose, when they don't even know what X is?
All they really want to do is to say X is a function of my field of specialty, and you really should stop paying attention to X and start paying attention to me.
For most cases of X, X is more interesting than evolutionary psychology. And the study of social phenomena as they manefest themselves to us today is infinitely more likely to provide us with answers and progress than the study of evolutionary biology.
And as economics suffers from a crisis of credibility, it may seem only natural that the Economist would turn to economics' cousin evolution for a boost. But this totalizing system is not much better that the others we suffered through in the last century. One would hope the Economist would in the final instance make a stand for the particular against the sloppy totalizers.
