After the fact
Daniel Larison has a post up where he criticizes a David Brooks column. Here’s what Larison observes (Brooks’ quote within):David Brooks is right that culture and habits matter, but this one line rang false:There is the influence of the voodoo religion…

Levelling off of the “Obesity Epidemic”?
There’s a lot of media buzz right now about a new report in JAMA on the empirical trends on prevalence of obesity in the United States. You can read the whole paper here (too many tables, not enough graphs). Interestingly, like George W. Bush it seems …

Haiti & charity
A reader asked about donating to alleviate the suffering in Haiti. In particular, making sure that the donations don’t go toward religious or Leftist ends. My own personal assumption is in line with the recommendations of the The GiveWell Blog: A few notes: Unfortunately, “disaster relief” is not an area we’ve researched. When we’ve (very…

On the Y
Here’s the link to the new paper in Naure on the evolution of the human & chimp Y chromosome, Chimpanzee and human Y chromosomes are remarkably divergent in structure and gene content. ScienceDaily and The New York Times have summaries up. Wonder if th…

The Confucian conservatives
I highly recommend John Keay’s China: A History to any readers who wish to familiarize themselves with this civilization. Keay’s narrative is aimed at the general reader. Specialists will no doubt find themselves irritating by the simplifications, or even errors (I’m not a China specialist but even I picked out a factual error here and…

The Dark Age Mighty Whitey
This week David Brooks has a column up on the messianic variant of the “Mighty Whitey” motif. Steve points out that this is a relatively old genre, with roots back to the Victorian period. And, it also has basis in fact. Consider the White Rajahs of Sa…

Localizing recent positive selection in humans using multiple statistics
Online this week in Science, a group presents a method for identifying genes under positive selection in humans, and gives some examples. I have somewhat mixed feelings about this paper, for reasons I’ll get to, but here’s their basic idea:Readers of t…

Don’t be an infidel?
Interesting possibility that Google is engaging in self-censorship in regards to Islam. If true the motive is likely more profit that fear (via Abhi). Share/Save

On the cusp
Lots of talk about how the “underwear bomber” was from a wealthy and cosmopolitan background in the media. Like the poverty = crime meme, the poverty & backwardness = terrorism meme is still floating around, though the evidence of the past decade o…

Over the past decade there have been many warnings about Global Warming; precise extrapolations of temperature increases and projections of sea level rise.

How Chinese relate to each other and the Japanese
Last month I pointed to a paper on Chinese population structure, Genomic Dissection of Population Substructure of Han Chinese and Its Implication in Association Studies. One to note was that the average FST differentiation Han populations was on the or…

On signals & design
Somehow SR’s email address was added to Newsmax’s mailing list for ad buys. The pitch is that one will reach affluent readers. But they undermine their message by formatting their HTML emails in a garish 1997 Frontpage-generated style. I thought they were being ironic, but I think they’re sincere. Share/Save

We are a social animal
Occasionally we get emails like this: Up until now I thought I was the rarest of all ducks. A conservative atheist. I read Heather MacDonald’s piece in the Wall Street Journal today and was pleased to find I am not alone. I would love to know more about the organization. Yours truly, [name omitted] One…
