More on Morality and Religion

The tie between religions and morality is one many probably have picked up on from their own personal experiences. This study looks at the “chicken and the egg” problem regarding morality and religion….

“Some scholars claim that religion evolved as an adaptation to solve the problem of cooperation among genetically unrelated individuals, while others propose that religion emerged as a by-product of pre-existing cognitive capacities,” explains study co-author Dr. Ilkka Pyysiainen from the Helsinki Collegium for Advanced Studies. Although there is some support for both, these alternative proposals have been difficult to investigate.

Dr. Pyysiainen and co-author Dr. Marc Hauser, from the Departments of Psychology and Human Evolutionary Biology at Harvard University, used a fresh perspective based in experimental moral psychology to review these two competing theories. “We were interested in making use of this perspective because religion is linked to morality in different ways,” says Dr. Hauser. “For some, there is no morality without religion, while others see religion as merely one way of expressing one’s moral intuitions.”

Just to add a small point, there is evidence to suggest that morality exists without religion. For an easy example, what libertarians often call “natural rights”.

Citing several studies in moral psychology, the authors highlight the finding that despite differences in, or even an absence of, religious backgrounds, individuals show no difference in moral judgments for unfamiliar moral dilemmas. The research suggests that intuitive judgments of right and wrong seem to operate independently of explicit religious commitments.

“This supports the theory that religion did not originally emerge as a biological adaptation for cooperation, but evolved as a separate by-product of pre-existing cognitive functions that evolved from non-religious functions,” says Dr. Pyysiainen. “However, although it appears as if cooperation is made possible by mental mechanisms that are not specific to religion, religion can play a role in facilitating and stabilizing cooperation between groups.”

Perhaps this may help to explain the complex association between morality and religion. “It seems that in many cultures religious concepts and beliefs have become the standard way of conceptualizing moral intuitions. Although, as we discuss in our paper, this link is not a necessary one, many people have become so accustomed to using it, that criticism targeted at religion is experienced as a fundamental threat to our moral existence,” concludes Dr. Hauser.

Sex, Status, and Vertical

From the Boston Globe….

When describing positions of relative status, people often use adjectives related to height, as in “top choice,” “up the food chain,” or “high end.” A recent study finds that this association even extends to judgments about the attractiveness of the opposite sex. Women rated pictures of men as more attractive when they were presented in the top half of a screen. Men, however, rated pictures of women as more attractive when they were presented in the bottom half of a screen. The authors see this as consistent with the evolutionary view that men prefer submissive mates, while women prefer dominant ones.

From "Downright Sexy: Verticality, Implicit Power, and Perceived Physical Attractiveness", by Brian P. Meier and Sarah Dionne….

Abstract text

Grounded theory proposes that abstract concepts (e.g., power) are represented by perceptions of vertical space (e.g., up is powerful; down is powerless). We used this theory to examine predictions made by evolutionary psychologists who suggest that desirable males are those who have status and resources (i.e., powerful) while desirable females are those who are youthful and faithful (i.e., powerless). Using vertical position as an implicit cue for power, we found that male participants rated pictures of females as more attractive when their images were presented near the bottom of a computer screen, whereas female participants rated pictures of males as more attractive when their images were presented near the top of a computer screen. Our results support the evolutionary theory of attraction and reveal the social-judgment consequences of grounded theories of cognition.

It’s too bad the study only tested a people from a very limited group….

Participants were 79 Gettysburg College students with a mean age of 19.03 (SD = 1.09) years. Of these participants: 29 were male and 50 participants were female; 75 participants identified themselves as Caucasian, two identified themselves as Asian, and two identified themselves as “other.”

Bonobo Cannibalism

So much for the “hippy chimp”. Bonobos, known for their peaceable ways and casual sex, have been caught in the act of cannibalism.

An account of a group of wild bonobos consuming a dead infant, published last month, is the first report of cannibalism in these animals – making the species the last of the great apes to reveal a taste for the flesh of their own kind.
[...]
Though bonobos mostly eat fruit and leaves, they are known to hunt monkeys and the small antelopes called duikers. But Fowler noted signs that this meal was somehow different. More individuals got a taste of the infant than is typical when the apes share meat. They also spent 7½ hours eating the body – longer than they take over a similar-sized monkey. Some even played with it. “If they just think of it as another piece of meat, why do they behave differently with it?” he asks.

John Hawks made the comment

Of course you’ll see a lot of rare things when you spend enough time watching. If the average individual can go through her entire life without eating the flesh of a conspecific, it’s not probably very important. But seeing it rarely puts it in the range of behavior — common enough in evolutionary timescales for either natural or cultural selection to pick it up if it were useful.

The Great Southern Migration Theory

Over at Kambiz Kamrani’s Anthropology.net, Terry Toohill has written and posted an interesting article on The Great Southern Migration Theory. The theory looks at the distribution of Y-DNA Haplogroup T (and to a lesser extent Y-DNA Haplogroup L).

I realise it’s risky to draw conclusions about ancient migrations from modern haplogroup distribution, but I believe that if we consider the possibility that Y-hap T was originally associated with some sort of a boating expansion we are easily able to explain the spotty distribution.
[...]
What is the possibility that L and T originate even further east? Y-haps N/O and P have become so widespread it’s possible to come up with almost any theory concerning their place of origin. But among L and T’s other close relations are S and M. Found in New Guinea, Melanesia and Australia, a region we know people must have reached using boats of some sort a very long time ago.

So we have evidence for a southern coastal migration. [...] The fact that Y-hap T, along with L to some extent, appears to have effortlessly established itself in all the desirable coastal and riverine ecosystems along the southern Eurasian margin suggests that this habitat was actually unoccupied until T’s expansion. And that argues against any other more ancient great southern coastal migration.

Bilderberg Group: Wasn’t this just a conspiracy theory?

There was an article back in November 22nd, 2009 that talked about the first president of the EU — Herman Van Rompuy — wanting a new Euro tax. In the article there is mention of the Bilderberg Group as such…

Within days of taking office in January, the former Belgian prime minister will put his weight behind controversial proposals already floated by the commission’s head, José Manuel Barroso, for a new “Euro tax”.

He will add credence to Mr Barroso’s plans, to be formally tabled in the New Year, by arguing for a Euro-version of a “Tobin Tax” – a levy on financial transactions already floated by Gordon Brown as a solution to the international banking crisis. It would result in a stream of income direct to Brussels coffers, funding budgets that critics say are already rife with waste and overspending.

Mr Van Rompuy, 62, who was appointed to the newly-created £320,000-a-year post at last week’s special EU summit, set out his stall on direct Euro-taxes during a private speech at a recent meeting of the Bilderberg group of top politicians, bankers and businessmen. The group officially meets in secret, but when selected details of his remarks leaked out, his office was forced to issue a public statement on his behalf.

“The financing of the welfare state, irrespective of the social reform we implement, will require new resources,” he said. “The possibility of financial levies at European level needs to be seriously reviewed.”

(Emphasis mine.)

If you believe the some of the conspiracy theories out there, it would look like people aren’t even really trying to keep secrets about it anymore.

King Tut’s DNA, Coming Soon

One of the great remaining mysteries of ancient Egypt, the lineage of the boy-pharaoh Tutankhamun, may soon be solved [...]

Zahi Hawass told AFP he has scheduled a news conference for February 17 [2010] in the Cairo Museum to unveil the findings from DNA samples taken from the world’s most famous pharaoh.

The announcement will be “about the secrets of the family and the affiliation of Tutankhamun, based on the results of the scientific examination of the Tutankhamun mummy following DNA analysis,” Hawass said.

After this question is answered though, the question then becomes, was King Tut representative of Egyptians in general? And what was the Egyptian royalty (genetically) like before him?

Scots and U.S. Scientists

Blogger Ron Guhname (not his real name) aka the Inductivist (not his real name either) did a little digging into the General Social Survey and found that, in the U.S., Scots — people of Scottish descent — seem to be disproportionately represented in the Natural Sciences in the U.S.

(Warning, there is a small N involved. So taking this with a grain of salt might be prudent.)

The General Social Survey asks respondents (American) about occupation and ethnic background. Here are the percent of all natural scientists in each ethnic group (those who are less than 5% of the total are excluded):

The ratio refers to the share of natural scientists compared to the ethnic group’s share of the total population. You can see that Americans of English, Irish, Italian and especially Scottish descent are natural scientists in disproportionate numbers.

Correlation is not causation, of course. But when we see correlation we wonder if there is causation involved.

It would be interesting to see how representative these U.S. Scots are representative of Scots in Scotland. Also, do Canadian Scots seem as gifted at Science? What about Australian Scots?
