Afrikaner theocratic totalitarianism
The State is instituted by God to exercise His wrath upon evildoers, and to praise and protect those who live righteously. We see that the State is called upon to administer righteousness in society. (p. 43)According to Raath, then, the South African constitution should be set aside, its liberal freedoms severely curtailed, and the government should "demand obedience to both tables of the
Ten Commandments" (p. 52). Chillingly, Raath goes on to say that he "rejects the ridiculous idea of the right to life, according to which the right to life for evildoers is guaranteed" (p. 57) and thus apparently advocates the death penalty for blasphemy, homosexuality, witchcraft, adultery... As I said. Batshit. Crazy.
Incidentally, an unprovable but highly plausible argument I've heard a couple of times is that the divergence between Dutch Calvinism (which became far more liberal over time) and Afrikaner Calvinism (which until recently did not) is due to the Enlightenment. Holland, of course, has long been an important intellectual center, and Dutch culture was thus strongly influenced by the Enlightenment. South Africa, on the other hand, was isolated from these developments and could thus not benefit from them. The result? The enormous difference between South Africa's shameful, intolerant and illiberal political and cultural history and Holland's mostly tolerant and liberal political history. Of course... this claim is untestable and speculative and, given that I'm a fan of the Enlightenment, I could be suffering from confirmation bias. But, it's certainly interesting and plausible.

Fun with RSS
PostRank, bless it, adds a third option... Using a PageRank-esque algorithm (that takes account of the number of comments, Diggs, inbound links, del.ico.us saves and so on) PostRank gives a feed's individual posts a score of between 1 and 10, and these rankings in turn allows filtering for quality. So, for example, I love Phyrangula but I can handle only so many three-line posts about some random US politician defending creationism (or whatever). So all I have to do is add Phyrangula's feed to PostRank, specify that I only want to see "Great" posts (i.e. those with a PostRank score higher than 6), and then subscribe to the custom feed that gets generated, using my customary feed reader. The result? No to Jolly Squidmas wishes, but yes to the conversion of a prominent atheist blogger to Christianity. Best of all, there are two helpful Firefox addons that works with the service: a feed manager that makes handling all those RSS's simple, and AideRSS Google Reader integration that improves Google Reader with various PostRank tools.
Of course, the filtering is only as good as the algorithm, but so far I'm very impressed with the results. Obviously, also, there are a bunch of other ways PostRank is useful; I've only focused on the filtering because I'm so keen to reduce my RSS reading duties...
DNA & Dating
My bottom line, for what it's worth, is that it's plausible to think this kind of genetic matching is an improvement over sheer chance, but I doubt very much it'll be superior to our evolved sexual psychology. (Although I do suspect it'll in general predict compatibility better than questionnaire-based online matching services). So, if you're wealthy and lonely, give it a try... otherwise, stick to the singles bars.

Participate in an experiment...
Oh, and I see Wiseman appears on this week's edition of The Skeptics' Guide to the Universe podcast. I haven't heard the interview yet, but I'm sure it'll be worth a listen.
Licking wounds
Doubts aside, this is fascinating stuff. Why? Because if wound licking really promotes healing (but not obviously so), and all human beings lick their wounds, then it's plausible to suggest this behavior is adaptive. Or, in other words, if it increases fitness and if nearly everybody does it, it's possible that licking one's wounds is a behavior that evolved by natural selection. (Do note that I say 'plausible' and then 'possible'. The evidence I've presented here is merely suggestive and far, far from definitive). Moreover, if wound licking behavior occurs widely among mammals - and a couple of searches in Google Scholar suggests it is, including among several species of non-human primate - then it might be a very ancient behavior indeed. That is, because specific characteristics that different but related organisms share is likely to be inherited from a common ancestor, wound licking could have arisen tens of millions of years ago.
So next time you instinctively pop your injured finger into your mouth, remember that you're engaging in a behavior that may be significantly older than even the hominid lineage. You animal you.

Video: Atul Gawande
We are used to thinking that a doctor’s ability depends mainly on science and skill. The lesson from [the preceding stories] is that these may be the easiest parts of care. Even doctors with great knowledge and technical skill can have mediocre results; more nebulous factors like aggressiveness and consistency and ingenuity can matter enormously.Anyway, I highly recommend both the video and the article.

Gladwell's latest
There are certain jobs where almost nothing you can learn about candidates before they start predicts how they’ll do once they’re hired. So how do we know whom to choose in cases like that? In recent years, a number of fields have begun to wrestle with this problem, but none with such profound social consequences as the profession of teaching.
...
In teaching, the implications are even more profound. They suggest that we shouldn’t be raising standards [for hiring teachers]. We should be lowering them, because there is no point in raising standards if standards don’t track with what we care about. Teaching should be open to anyone with a pulse and a college degree—and teachers should be judged after they have started their jobs, not before... [The teaching profession] needs an apprenticeship system that allows candidates to be rigorously evaluated.
Once again, say it with me now: p-a-r-e-i-d-o-l-i-a

Grief hallucinations
The dead stay with us, that much is clear. They remain in our hearts and minds, of course, but for many people they also linger in our senses—as sights, sounds, smells, touches or presences. Grief hallucinations are a normal reaction to bereavement but are rarely discussed, because people fear they might be considered insane or mentally destabilised by their loss. As a society we tend to associate hallucinations with things like drugs and mental illness, but we now know that hallucinations are common in sober healthy people and that they are more likely during times of stress.(Also check out Vaughn's blog entry on the article.)
Prayer in SA schools
The point, Jacob Zuma, is that we don't need pious school leavers; we need ones who are developing razor-keen skills so that they can keep this country on the road to modernity. I'd like some of them to become super-healers, the kinds of doctors, nurses and medical researchers who are so good at what they do that the ruling party won't have to suffer the indignity of sending its ailing leaders off to the hospitals of former colonisers to get decent medical treatment. So let's leave the teachers to do their jobs -- teach -- and spare them the distraction of daily incantations.Joubert also writes a blog, Scorched... why hadn't I heard about her previously?!

Skeptics' Circle 101: The African Edition
The African Invasion
I have a large list of African science and skeptical blogs in my blogroll, under "African Science Blogroll" (please let me know if you know of any more!) but here are some notable blog entries from African skeptics over the last while...
First up is James Hough of Acinonyx Scepticus with a fascinating post on the application of evolutionary psychology's error management theory to scientific skepticism.
Owen Swart of 01 and the universe introduces and debunks the tokoloshe, a common Southern African superstition sure to interest many of you. (It's a bit like a really evil leprechaun).
Probably South Africa's best known skeptical activist is George Claassen, who runs Prometheus Unbound. George has two great recent entries: on 13 things we should tell our children and on creationist stupidity in the South African media.
Angela, The Skeptic Detective, admirably dissects a crazy quack chain email that claims rubbing Vicks Vaporub on your feet will cure your of a cough.
Finally, a couple of entries from a blog new to me, The Skeptical Blacksheep: silly Christians yet again being fooled by pareidolia and a deeply troubling instance of censorship at the CSRI (an important research outfit in South Africa).
Everybody else...
Leading the non-African pack is Techskeptic's Data Daily with an excellent explanation of why fMRI cannot be used to justify pseudoscience.
Skeptico explains how there is a big difference between race, sex, sexual orientation and handicap status on the one hand, and religion on the other, which means anti-discrimination laws cannot be used to justify banning 'blasphemy'.
Happy Spirochete of Ideas are Dangerous claims Michael Egnor is a stupid poopy head. I, for one, am not skeptical of that claim...
Greta Christina, in usual good form, explains that the universe is not perfect or 'fine tuned'.
Karen Stollznow, The Skepbitch, discusses bigfoot (aka Bigfootae Ambiguus Subjectico).
Next up is Scepticon (all the way from New Zealand, it seems), who interviews Alison Campbell (of BioBlog).
Also from Down Under is Kylie (the PodBlack Cat) on a play that promotes the 9/11 conspiracy nonsense. Who would have though such a thing possible?!
Aerik Knapp-Loomis has a challenging post about feminism and skepticism, specifically, he takes Phil Plait to task for allegedly sexist comments.
Politics and science. Science and politics. It'll never work... or at least not as long as a chiropractor is the Minister of Science, as is the case now in Canada, as Polite Company explains.
Our next host, Happy Jihad's House of Pancakes (how did he come up with that name?), has a Modest Proposal... (about drugs).
Next, Einar from Waffle ("Devoid of all delusions save those of observation, experience and reflection") reviews CS Lewis' The Screwtape Letters. To put it lightly, he was not impressed, and I can see why...
The Lay Scientist submitted an appropriately indignant post on science reporting so preposterously bad that even the NHS was pissed off.
Finally, there is Life, the Universe, and One Brow, with three posts skewering philosopher Thomas Nagel for claiming (among other things) that evolution and design are not alternatives.
AiG-obsessed Bing from Happy Jihad's House of Pancakes will host the next edition of the Circle on December 18th. If you'd like to contribute, check out the guidelines and then email your contributions to the host.
Unusual articles
One beautiful illustration of Wikipedia's greatness is its comprehensive and fascinating list of unusual articles. A small sampling of the fun:
- "Japanese toilets" (Japanese people can be weird),
- "David Hahn" (a 17 year old boy who tried to build a nuclear reactor in his backyard),
- "Heavy metal umlaut" (to prove your band is ütterly hardcore),
- "Gay bomb" (weapon the US miliarty wanted to develop to, erm, "soften up" enemies),
- "GoldenPalace.com Monkey" (a species of monkey named after an internet casino),
- "Acoustic Kitty" (CIA wanted the use cats as spies), and
- "Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo" (an example of a grammatically correct sentence that is nearly impossible to parse).
Nature vs. Mbeki
The editorial also mentions that UCT economist Nicoli Nattrass (a previous lecturer of mine) made a very similar estimate of the lives lost to South Africa's idiotic policies in a study published earlier this year.The needless deaths that occurred in South Africa prompt reflection on Mbeki's now infamous presidential AIDS advisory panel on the link between HIV and AIDS, the fate of which was chronicled in this journal in 2000–01. Its inconclusive report enabled Mbeki and his cabinet, who must bear collective responsibility, to portray this link as "deeply contested, and contestable", to quote Nattrass. Certainly, the AIDS dissidents (much criticized by Nature in the past) couldn't wait to participate in the panel. But should orthodox scientists have signed up?
Even in retrospect, this is a difficult question to answer. Once leading South African scientists, such as Malegapuru Makgoba, then president of the South African Medical Research Council and an outspoken critic of Mbeki, had agreed to do so, others were bound to follow suit in support. In turn, members from outside of the country in good faith believed that their colleagues deserved similar support, and so agreed to participate. Ultimately it became clear that these efforts were a waste of time, as there was no possibility of consensus being reached among the panel's two diametrically opposed camps.
Thabo Mbeki is no doubt experiencing immense cognitive dissonance at the moment. I don't want to sound callous, but I hope he's not sleeping.

Irrationality kills
Religion is an insult to human dignity. With or without it you would have good people doing good things and evil people doing evil things. But for good people to do evil things, that takes religion.Except, in this case, religion wasn't to blame, it was a kind of weirdly diffuse but prickly anti-Western pro-Africanist ideology. This ideology - quite possibly, it seems to me, one outgrowth of Mbeki's painful emotional insecurity - predisposed Mbeki to reject science and logic precisely because he thought of it as "Western". And, perhaps more importantly, if the orthodox explanation for AIDS were correct, it would imply, Mbeki thought, that Africans were uniquely sexually voracious, for how else could you explain the fact that Africa has by far the highest incidence? All these worries are reflected in a newly released letter (almost certainly drafted by the president himself) that Mbeki's office sent to the then head of the Medical Research Council, William Makgoba in December 2000.
I'm not going to deconstruct Mbeki's letter in detail - I don't have the time or patience and, besides, it would an exercise in futility. But I will note that there just is no meaningful sense in which science is "Western". While science no doubt arose in the West (in Western Europe during the Age of Reason to be precise) that obviously doesn't mean it cannot be a universally good way of finding out what's true. And, to address Mbeki's other concern, Africans are not uniquely licentious, HIV is more common here because it arose on the continent possibly as far back as 1884 and thus became endemic. (Moreover, there is evidence that, due to the Black Plague of all things, people of European descent are fortuitously less prone to be infected (pdf) and, due to malaria of all things, people of African descent are fortuitously more prone to be infected).
Anyway, two breathtakingly silly quotes from Mbeki's letter if you can't stand reading the whole thing:
Among the socio-biological factors that have shaped our society over three and a half centuries are the western scientists who helped to create the psychological dependence that obliged Africans to depend on these western scientists for solutions to problems they were otherwise uniquely positioned to solve.
These are the people who created the ‘Eurocentric African university' which you sought to overthrow and replace with a truly African University.
It is they who created a "scientific" view of the African that made us the very essence of everything despicable in human society and behaviour.
(...)
What is said is that the questions the President is raising were answered by western scientists at least 15 years ago.
It is also said that the ‘dissidents' the President speaks to lost the scientific argument to other western scientists at least 15 years ago.
After this seemingly powerful argument, it is assumed and intended that our President should then admit the error of his ways with regard to the matter of HIV/AIDS and shut up!
All that is said is that Western science long made a ruling!
The question is then asked - what right does a non-scientist have, such as our President, to question matters that science in Britain, France, Portugal and the United States answered many years ago!
The real question however that those who oppose President Mbeki are asking is, what right does any African have to question the findings of western science, regardless of whether he or she is a scientist or not!

Video: Brian Ferguson on war
While I don't agree with Ferguson's conclusion, the interview is highly recommended if you are at all interested in prehistory or human evolution.
Quote: Lionel Tiger
I dare say that it remains overwhelmingly the case in the social sciences that almost everywhere it is possible to receive a doctoral degree without studying any other species than humans. Even then, the work is likely to involve people and their behavior in the past generation and in a highly limited geographical area. This is wholly understandable, yet intellectually, it is akin to studying the whole of geology but focusing exclusively on Minnesota or doing botany while ignoring photosynthesis.
The great divide in anthropology
On one side are the evolutionary anthropologists. "(They believe) our behaviour is based on things that we did to find mates in our years of evolution," says Alex Bentley, a lecturer in anthropology at Durham University. "Then we have the social anthropologists. Some of them really strongly reject this kind of thinking. They consider it reductionist. They are focused on the specifics of culture."
Put crudely, social anthropologists describe and compare the development of human cultures and societies, while evolutionary anthropologists seek to explain it by reference to our biological evolution. The two sides of the one discipline are struggling to unite.
Do also have a look at the comments, there are some real corkers...

Skepticism and the Long Tail
As I said, interesting and provocative. Check it out.
Quackery in South Africa
Let's hope the Health Department under Barbara Hogan (the new Minister) starts doing something about these outrageous practices.
The dizzying diversity of human sexual strategies
Of course, it is not that simple. Women can be as sexually unrestrained as men. In fact, there is a huge overlap in the sociosexuality scores of men and women, with more variation within the sexes than between them. Some researchers are now trying to explain these subtleties in terms of biology and evolution.This rather reminds me of David Buss's answer to this year's Edge.org question, "What have you changed your mind about?" (which I blogged about here). Buss said he had realized that female sexual psychology is significantly more complicated than he had previously thought. Just so.
Take the fact that women's interest in casual sex can vary wildly over time. A hint that these short-term sexual encounters might have biological and evolutionary advantages comes from the timing of them. Several studies have shown that women are more likely to fancy a fling around the time they are ovulating - although there is no suggestion that this is a conscious decision. Not only that, says David Schmitt of Bradley University, Illinois, women show a shift in preference to men who look more masculine and symmetrical - both indicators of good genes. Women may have a dual strategy going, suggests Schmitt. "Humans infants need a lot of help, so we have pair-bonding where males and females help raise a child, but the woman can obtain good genes - perhaps better genes than from the husband - through short-term mating right before ovulation."
