The two cycles
I’m reading Brotherhood of Kings: How International Relations Shaped the Ancient Near East. The book basically outlines the international state system in the ancient Near East which fostered diplomatic relationships between the monarchies of the period. It is noted that this state system and diplomatic culture did not make it through the chaos which marks […]
Psychometrics, epigenetics and economics
Two papers of interest. IQ in the Production Function: Evidence from Immigrant Earnings (ungated). And Human Intelligence and Polymorphisms in the DNA Methyltransferase Genes Involved in Epigenetic Marking. My impression is that the focus on epigenetics has a higher-order social motive; even the sort of humanists who are involved with N + 1 have asked […]
Why educated women are having children
Matt Yglesias has posted some charts showing that
1) Childlessness among women is becoming more common
2) The variation of this state by education is disappearing
Here’s the chart which illustrates the second phenomenon:
I think the reason this may be occurring is a dilution of the sample bias of women who have higher education in relation to the […]
Amerindians of Brazil more numerous than you think
A few months ago I was thinking a fair amount about the Neandertals. One issue which became more stark to me due to that particular finding, that a few percent of the human genome seems to have derived from Neandertal populations, is the reality that genetic distinctiveness can persist long after cultural coherency is no […]
Tick-tock biological clock
There will be an interesting presentation tomorrow at the European Society of Human Reproduction & Embryology. Basically the researcher is going to present on a method for predicting when a woman will hit menopause. This part from the press release is the important bit:
“The results from our study could enable us to make a […]
The essence of pleasure
I highly recommend this discussion between Paul Bloom & Robert Wright. The topic under consideration is the psychology of pleasure, as reviewed in Bloom’s new book How Pleasure Works: The New Science of Why We Like What We Like. You can also find out about Bloom’s ideas in this exchange in Slate. The essentialism examined […]
First they came for Dave Weigel
Dave Weigel of The Washington Post has resigned over his juvenile postings on an e-list. Basically the postings allowed for Weigel’s mask to slip, and showed him to be a vulgar and immature young man in some contexts. That’s no different from many of us in the proper context. The e-list is now defunct because […]
Daily Data Dump – Friday
23andMe research article finally published. Dr. Dan MacArthur offers his take on a new PLoS Genetics paper which was published using 23andMe’s user base. Of course there’s already information coming out of 23andMe’s user community not getting into the academic literature, see this comment below.
Group Solidarity and Survival. For what it’s worth, I think group […]
What has Rome to do with Nairobi?
There are very few books which would attempt to connect the experiences of the 1st century British who lived through Roman conquest with the French under the Vichy regime in World War II. The The Rule of Empires: Those Who Built Them, Those Who Endured Them, and Why They Always Fall by Timothy Parsons attempts […]
The dismal gods
Larry Witham’s Marketplace of the Gods: How Economics Explains Religion is a manifestly ill-timed book. He states that “…around 2006 I began to notice a good deal of hoopla in the book market about economic explanations for just about everything-books that were best sellers.” Marketplace of the Gods was obviously written to capitalize on the […]
You have no privacy, deal with it
The Washington Post’s blogger-journalist Dave Weigel has a post up where he preemptively apologizes for stuff he posted on an “off-the-record” e-list,. Extracts are going to be published by a gossip site. Journalists are the tip of the iceberg; privacy is fast becoming a total fiction, remember that. We’re slowly drifting toward David Brin’s model […]
Daily Data Dump – Thursday
This Doctor Does What to 6-Year-Old Girls’ Clitorises? This reminds me of the possibly apocryphal story of a pediatrician being attacked in England because a really stupid outraged person was opposed to pedophilia. Here’s a sentence for the ages: ” Because much as Savage might like it to be, the world is not yet a […]
The English & Irish, together again
One of the peculiarities of the synthesis of 19th and early 20th historical linguistics and biological anthropology was the perception by many British thinkers that the English, as the scions of the Anglo-Saxons, were fundamentally a different race from the Celtic nations to their west, the Welsh and Irish, and the Scots to the north […]
Project your own probability
By now you’ve probably stumbled onto Wired’s profile of Sergey Brin, and his quest to understand and overcome Parkinson’s disease through the illumination available via genomic techniques. I want to spotlight this section:
Not everyone with Parkinson’s has an LRRK2 mutation; nor will everyone with the mutation get the disease. But it does increase the chance […]
Daily Data Dump – Wednesday
GDP PPP inhabitant by European region. Combining Italy or the UK into one GDP number is deceptive. Lombardy has twice the GDP PPP of much of southern Italy. The regional differences are not nearly as stark in Spain, where poor regions like Andalusia and Galicia exhibit less of a gap from prosperous regions. By the […]
Daily Data Dump – Tuesday
Sexual urges overcome cultural taboo. So it turns out that the female children of immigrants from conservative societies (South Asian and Islamic) are paying for hymen restoration surgeries. The more interesting question would be if these children become sexually conservative themselves, perpetuating the life history trajectory so that their own children have to go through […]
The future of fertility; more kids please
After my post yesterday on Bryan Caplan’s argument for having more children, I was curious as to what the public perceptions of the ideal number of children was in the General Social Survey. There’s a variable with large N’s which is already in there: CHLDIDEL. It asks:
What do you think is the ideal number of […]
ResearchBlogCast #9: Genetics, Fertility, And Disease
The 9th ResearchBlogCast is up. We talk about the recent paper on cystic fibrosis genetics which I blogged.
Daily Data Dump – Monday
I won the 3 Quarks Daily Science Prize. ‘Top quark’. Heh. “I” = Ed Yong. ‘nuf said.
Brown-eyed men perceived to be more dominant. Dienekes offers up a more banal explanation, that the disjunction between blue vs. brown-eyed males in dominance perception has to do with a correlation that’s a holdover from past population differences which […]
