Why unity through enforced assimilation doesn’t work

My wife and I are currently working our way through all five seasons of Babylon 5. It’s one of the most highly acclaimed science-fiction shows ever produced for television, so not having watched it was seriously hurting my street cred as an sci-fi geek. Anyway, in one of the first season episodes, The Geometry of Shadows, the command crew of the station is presented with an odd problem.

Members of one the minor races, the Drazi, have begun fighting one another for no apparent reason, and the escalating level of violence is threatening the security of the station, so the newly promoted Commander Ivanova needs to find a solution to the problem. To do that, she needs to find out why they are fighting. As it turns out, every once in a while, the Drazis put a number of sashes in a gigantic barrel, one for each Drazi. Half of the sashes are dyed purple, the other half green, so whichever colour of sash a Drazi draws out of the barrel determines which group he belongs in. As the Drazis explain, “Where there was one Drazi people, now there are two. The two fight until there are one.”

Fighting crime one broken window at a time

With crime in the spotlight in Malaysia (again), I thought I should highlight this article from The Economist. It’s about a series of experiments performed by Kees Keizer and his colleagues at the University of Groningen to determine the truth of an old idea: that physical disorder in the environment can lead people to commit crimes more readily. This is the same line of thinking that inspired New York’s efforts to fight more serious crimes by cracking down on minor offenses like graffiti, breaking windows and other forms of vandalism.

One such experiment took place in an alley in which people frequently parked their bicycles. To create a disorderly state, they covered the walls of the alley with graffiti while the walls were freshly painted in the orderly state. Under both conditions, a prominent “No Littering” sign was displayed in the alley. Once bicycles had been parked, the experimenters quickly moved in to put a fake advertisement flyer on the bike in such a way that it would have to be removed in order to ride the bike. When the owners came back, they had to choose either to remove the flyer and keep it on their person somehow, throw it onto the ground, or put it on another bike. The experimenters secretly observed and recorded these reactions and considered putting the flyer on another bike as an act of littering.

The final result was that when the walls were clean, only 33% of bicyclists littered, but if the walls were covered with graffiti, the figure increased to 69%. Other experiments in the same vein showed similar results. If the environment was clean and orderly, people were less likely to commit crimes or break the rules, but in a disorderly environment, people seemed to think that breaking the rules was no big deal.

I point this out because I think that it’s particularly relevant for Malaysia. This is after all the country where putting a prominent “Dilarang Buang Sampah” sign up anywhere guarantees that a pile of rubbish will show up at the spot. One of my pet peeves about Malaysians is that everyone thinks rules and laws are meant to be bent. Just look at the money-lender advertisements everywhere in places where they plainly don’t belong or traffic violations like double-parking. But as these experiments indicate, if you want to live in a safe and orderly environment, you need people to perceive the environment to be safe and orderly, and the only way to achieve that is by cracking down on all crimes, especially the small but highly visible ones, and enforcing the law to its strictest extent.

Recent Interesting Science Articles (Oct ’08)

Wow, I haven’t done one of these in a while since my Economist subscription lapsed. I only renewed it fairly recently. Anyway, here are the three most interesting science related news items that I’ve seen in October, with one of them from The Economist. Let’s start with that one first.

The biological causes and effects of homosexuality is one of the perennial questions when you try to explain human nature in scientific terms. The most obvious of these questions is why homosexuality, since it can in large part be attributed to genetic causes, persists when common sense dictates that homosexuals shouldn’t be in a good position to pass along their genes to the next generation? A recent article highlights one possible answer: genes that make men more feminine and genes that make women more masculine confer a reproductive advantage to the person who possesses them, so long as they do not actually push them into homosexuality.

Recent Interesting Science Articles (July 2008)

I haven’t been as up to date as I should this month, but nonetheless I have three articles. The first and the most exciting one is the announcement by NASA confirming the presence of water on Mars. Now, we’ve had indirect evidence of water for a while now, but this is the first time that a robot, in this case the Phoenix, has actually tasted it by melting a piece of ice. The next step will be to bring it to even higher temperatures to try to find any traces of carbon-based compounds.

Recent Interesting Science Articles (June 2008)

Wow, I haven’t done any updates for this in a while, so let’s make up for it by posting about four different articles, starting with the biggest science-related news this month. According to the U.S. National Snow and Ice Center, the North Pole may be, for a brief period, completely free of ice this summer. This is as alarming a symptom of global warming as anyone can imagine. While the scientists assure us that the melting of the polar ice cap should have no immediate ill effects, jokes about Santa Claus losing his home aside, it’s hard to deny that this should be seen as an extremely loud wake up call.

I have to admit that I was once a global warming skeptic myself but the scientific consensus now is that global warming is a real and human-induced phenomenon. What we should do about it is a different and complex matter of course, and I still reserve the right to mock greens for their conflicting rhetoric over it.

Recent Interesting Science Articles (Jan’08)

Three articles all on the subject of biology for this month. Science news website LiveScience had an article this month with a controversial angle: it cites a new study published in Psychopharmacology which found that male mice liked to fight for no reason other than to fight. The experiment involved first placing a male and a female pair of mice in a cage, then removing the female one and introducing another male “intruder” mouse. After the initial fight, the scientists arranged for the cage to be rigged such that when the mouse nose-poked a specific trigger, the intruder mouse would be able to return to the cage. They found that the resident mouse would actually do this often, suggesting that it regarded fighting as a sort of reward. The scientists then treated the mice with a drug known to block the effects of dopamine in parts of brain involved in rewards and found that this had the effect of reducing the mice’s tendency to nose-poke the trigger.

The controversy in this case comes from the researchers’ argument that the results would be equally applicable to humans as the reward pathway in humans and mice are similar and that aggression is highly conserved in vertebrates in general and mammals in particular. I believe that this remains to be proven but would not find it surprising if true. In any case, if indeed this were proven true, it would reinforce the usefulness of activities like sports and games to vent the natural aggression of human males.

Recent Interesting Science Articles (Dec’07)

Probably the most talked about scientific issue that’s been making the rounds recently is the news is that not only has human evolution not stopped since the advent of modern technology, a previously popular view, but has in fact actually accelerated. As this article in ABC News notes, in a recent paper published in the Proceedings of the National Academy of Sciences in the United States, researchers discovered that by comparing the DNA of humans and chimpanzees since the two species diverged six million years ago there were not enough differences between the two sets of DNA to account for the currently observed rate of change. Therefore, they take this to mean that human evolution has substantially accelerated since the appearance of modern humans 40,000 to 50,000 years ago.

Moreover, they find that different populations of humans have been evolving in different ways. The lighter skin colour of Asians and Europeans compared to Africans is one example, as an adaptation to allow more absorption of vitamin D in areas with less sun. Another example is the disappearance of the lactase enzyme that allows digestion of fresh milk in China and most of Africa where dairy farming is less common than in Europe.
