For the past few months I've been following The Givewell Blog. Here's a recent post, Why are we always criticizing charities?: Recently, we've criticized (in one way or another) many well-known, presumably well-intentioned charities (Smile Train, Acumen Fund, UNICEF, Kiva), which might lead to some to ask: should GiveWell focus on the bad (which may discourage donors from giving) as opposed to the good (which would encourage them to give more)? Why so much negativity and not more optimism? The fact is, we are very optimistic about what a donor can accomplish with their charity. Donor's can…
In the comments below, vanya states: But razib, upstate New York is not New England. I've never heard of "Greater New England." As a kid in New Hampshire I always understood that New England was superior to New York state, which was mostly a nest of Dutchmen and Tories in 1776 anyway. I never heard of "Greater New England" explicitly until I read this article by Michael Lind. I say explicitly because implicitly the region is obvious. You even know this from the biographies of prominent New Englanders, the perigrinations of Joseph Smith and John Brown follow the arc of Greater New England,…
Why Tiger's endorsement empire is safe: And as indiscretions go, this is not Michael Vick, say sports marketers. This is not Michael Phelps. This is not Kobe Bryant. Not yet, anyway. "I'm convinced that this will not cause the end of Tiger Woods Inc. as we know it," said Paul Swangard, managing director of the University of Oregon's Warsaw Sports Marketing Center. Probably Woods will still make gajillions of dollars in endorsements. Vick and Bryant's transgressions were much more serious. But are professional golfers graded on the same curve as NBA or NFL athletes? I'm skeptical.
We May Be Born With an Urge to Help: What is the essence of human nature? Flawed, say many theologians. Vicious and addicted to warfare, wrote Hobbes. Selfish and in need of considerable improvement, think many parents. But biologists are beginning to form a generally sunnier view of humankind. Their conclusions are derived in part from testing very young children, and partly from comparing human children with those of chimpanzees, hoping that the differences will point to what is distinctively human. The somewhat surprising answer at which some biologists have arrived is that babies are…
A friend of mine pointed me to an interesting weblog, Here in Glitner. From the "About" page: Reflections from my life as a Muslim, perspectives on Islam in my true life as a non-Muslim. I was a Muslim woman, a Muslim wife, a Muslim mother, a Muslim sister. I wore hijab, abstained from pork, obeyed my husband, studied quran and sunnah, and avoided all forbidden and doubtful things as much as I could. And then, slowly, from the blip of one thought to a full-blown realization more than five years later, I emerged into my true life, into reality, and realized my atheism. As you will read,…
This article pointed me to this interesting paper, Rapid adaptive evolution of northeastern coyotes via hybridization with wolves: The dramatic expansion of the geographical range of coyotes over the last 90 years is partly explained by changes to the landscape and local extinctions of wolves, but hybridization may also have facilitated their movement. We present mtDNA sequence data from 686 eastern coyotes and measurements of 196 skulls related to their two-front colonization pattern. We find evidence for hybridization with Great Lakes wolves only along the northern front, which is…
Wet phases in the Sahara/Sahel region and human migration patterns in North Africa: The carbon isotopic composition of individual plant leaf waxes (a proxy for C3 vs. C4 vegetation) in a marine sediment core collected from beneath the plume of Sahara-derived dust in northwest Africa reveals three periods during the past 192,000 years when the central Sahara/Sahel contained C3 plants (likely trees), indicating substantially wetter conditions than at present. Our data suggest that variability in the strength of Atlantic meridional overturning circulation (AMOC) is a main control on vegetation…
I've been crunching some county-by-county data at one of my other weblogs: Where the fat folks live Diabetes and obesity The white vote for Obama, by county & correlates Are over-leveraged counties seeing an increase in food stamp usage?

Open Secrets has data on members of the House and Senate in relation to their net worth. Here are some descriptive statistics: Democrats & Republicans: 25th percentile = $228,006 Median = $791,004 75thth percentile = $2,962,519 Mean = $6,438,210 Republicans: 25th percentile = $269,007 Median = $999,381 75thth percentile = $3,421,512 Mean = $6,010,456 Democrats: 25th percentile = $217,001 Median = $718,756 75thth percentile = $2,516,033 Mean = $6,731952 Let's limit to those who have positive net worth (greater than zero) and less than $50,000,000. This is about two standard deviations…
The New York Times has an article on cousin marriage that's up. Here's some important bits: Shane Winters, 37, whom she now playfully refers to as her "cusband," proposed to her at a surprise birthday party in front of family and friends, and the two are now trying to have a baby. They are not concerned about genetic defects, Ms. Spring-Winters said, and their fertility doctor told them he saw no problem with having children. The couple -- she is a second-grade teacher and he builds furniture -- held their wedding last summer on a lake near this tiny town in central Pennsylvania. But their…
Last week I pointed to numbers on evolution and the Muslim world. The New York Times has an article up about the conference which inspired my investigation into that topic. The reporter focuses on the rote learning and creativity as the factors behind a lack of knowledge or understanding of evolutionary theory. Plausible, but really unlikely. East Asian nations have the same issues (which they are trying to reform), but acceptance of evolution is high there. In fact, even in non-developed nations such as the Philippines acceptance of evolution can be high. It is higher than in the United…
The state of China has 1/5 of humanity within its borders, so it's genetic structure is of interest. It is obviously important for medical reasons to clarify issues of population structure so that disease susceptibility among the Han is well characterized, in particular with the heightened medical needs of an aging population in the coming generation. And of course, there are the nationalistic concerns. About 20 years ago L. L. Cavalli-Sforza reported that his South Chinese samples were genetically closer to Southeast Asians than North Chinese in The History and Geography of Human Genes.…
A new paper in PLoS ONE, Evaluation of Group Genetic Ancestry of Populations from Philadelphia and Dakar in the Context of Sex-Biased Admixture in the Americas, doesn't add much to what we know. They looked at a several hundred individuals who are self-identified as African American and European American, as well as 49 Senegalese from Dakar. Additionally, they reanalyzed data from Latin America from whites and blacks in Brazil, as well as a group of mixed Cubans. They found what you might expect to find, African and Native ancestry shows a female bias, European ancestry shows a male bias. But…
Since The Origin of Species was published 150 years ago many articles on evolution are seeing the light of day today. Normally I'm all in favor of this, I ♥ evolution. But it also means that woolly thinking is put out there as conventional wisdom as journalists simply act as stenographers for any scientist who's in their rolodex. Some of the quotes in this National Geographic article make me want to tear my hair out. Ian Tattersall, a paleoanthropologist, decides to offer up his opinions as a population geneticist: "Everything we know about evolutionary change suggests that genetic…
In medical news which won't be surprising to anyone, Ethnic Variation in Fat and Lean Body Mass and the Association with Insulin Resistance: Objective: Our objective was to compare total body fat to lean mass ratio (F:LM) in Aboriginal, Chinese, European, and South Asian individuals with differences in insulin resistance. ... Results: After adjustment for confounders and at a given body fat, South Asian men had less lean mass than Aboriginal [3.42 kg less; 95% confidence interval (CI) = 1.55-5.29], Chinese (3.01 kg less; 95% CI = 1.33-4.70), and European (3.57 kg less; 95% CI = 1.82-5.33)…
FuturePundit points me to a new paper on the Toba explosion, Environmental impact of the 73 ka Toba super-eruption in South Asia: The cooling effects of historic volcanic eruptions on world climate are well known but the impacts of even bigger prehistoric eruptions are still shrouded in mystery. The eruption of Toba volcano in northern Sumatra some 73,000 years ago was the largest explosive eruption of the past two million years, with a Volcanic Explosivity Index of magnitude 8, but its impact on climate has been controversial. In order to resolve this issue, we have analysed pollen from a…
Cannibalism is a controversial topic. It is routine for particular societies to accuse "barbarians", enemies, or evil mythological figures, of cannibalism. When it comes to the archaeological record some skeptics have claimed that like "sacred objects" too often human remains found in peculiar circumstances are ascribed to human sacrifice or cannibalism. In Did Adam and Eve Have Navels? Martin Gardner lays out the skeptical case for why cannibalism is rare to non-existent, and rather something which emerges from the imaginations of ethnographers and archaeologists, or is rooted in…
National Geographic has an interesting piece of ethnographic travel writing up on the Hadza of Tanzania. The Hadza are one of the few remaining hunter-gather populations in the world, and their language is an isolate which has clicks. There's a bit too much "noble savage" archetype loaded into the piece, but this portion is of note: The chief reason the Hadza have been able to maintain their lifestyle so long is that their homeland has never been an inviting place. The soil is briny; fresh water is scarce; the bugs can be intolerable. For tens of thousands of years, it seems, no one else…
I found this SNL sketch about an Obama/Jintao press conference very funny.
