In a review to be published in the May 18 issue of the journal Science, Jonathan Haidt, associate professor of psychology at the University of Virginia, discusses a new consensus scientists are reaching on the origins and mechanisms of morality. Haidt shows how evolutionary, neurological and social-psychological insights are being synthesized in support of three principles:

1) Intuitive primacy, which says that human emotions and gut feelings generally drive our moral judgments;

2) Moral thinking if for social doing, which says that we engage in moral reasoning not to figure out the truth, but to persuade other people of our virtue or to influence them to support us; and

3) Morality binds and builds, which says that morality and gossip were crucial for the evolution of human ultrasociality, which allows humans - but no other primates - to live in large and highly cooperative groups.

"Putting these three principles together forces us to re-evaluate many of our most cherished notions about ourselves," says Haidt, whose own research demonstrates that people generally follow their gut feelings and make up moral reasons afterwards. "Since the time of the Enlightenment," Haidt says, "many philosophers have celebrated the power and virtue of cool, dispassionate reasoning. Unfortunately, few people other than philosophers can engage in such cool, honest reasoning when moral issues are at stake. The rest of us behave more like lawyers, using any arguments we can find to make our case, rather than like judges or scientists searching for the truth. This doesn't mean we are doomed to be immoral; it just means that we should look for the roots of our considerable virtue elsewhere - in the emotions and intuitions that make us so generally decent and cooperative, yet also sometimes willing to hurt or kill in defense of a principle, a person or a place."

When offspring genetic engineering becomes possible I expect parental choices to produce bigger differences in how people morally reason. Conservative-leaning people will make their children morally reason even more strongly in the conservative style. The liberals will do likewise. So the size of the center will shrink. This will lead to deeper political divisions and perhaps civil war in some countries and wars between countries.

I also expect offspring genetic engineering to produce more other styles of moral reasoning including ones that are rare today and others that do not exist at all today. Who knows, maybe genetic engineering will move libertarianism up in the ranks of moral reasoning styles. [More]

Most of the houses have obviously been newly rebuilt, with brick walls and higher roofs. (Feng Shui and the cost of land may explain why houses stay on the same plots.) This is entirely typical for the area. It's dangerous to generalise about a huge country from anecdotal evidence; still, it is evidence that at least one substantial group of Chinese peasants are doing absolutely better than before, whether or not they are falling relatively behind the city-dwellers.

I have linked before about the growing male/female unbalance in Asia - particularly China. Here is more on the possible implications of the female shortage:

The long-term implications of the gender imbalance are largely guesswork because there is no real precedent for imbalances on such a scale. Some Chinese experts speculate, off the record, that there might be a connection between the shortage of women and the spread of open gay life since 2001, when homosexuality was deleted from the official Classification of Mental Disorders. It is possible to dream up all kinds of scenarios: Mumbai and Shanghai may soon rival San Francisco as gay capitals. A Beijing power struggle between cautious old technocrats and aggressive young nationalists may be decided by mobs of rootless young men, demanding uniforms, rifles, and a chance to liberate Taiwan. More likely, the organized crime networks that traffic in women will shift their deliveries toward Asia and build a brothel culture large enough to satisfy millions of sexually frustrated young men.
