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 […]
To be fruitful and multiply
Over at The Wall Street Journal Bryan Caplan has an op-ed, The Breeders’ Cup: Social science may suggest that kids drain their parents’ happiness, but there’s evidence that good parenting is less work and more fun than people think. Bryan Caplan makes the case for having more children. Much of the op-ed focuses on behavior […]
Animal Apartheid
Here’s an article from Canada on the debate about whether hybridization should be discouraged. I understand the impulse toward preserving nature as it is, but the drive for presumed purity seems almost fetishistic. Consider this sentence: ” Or could hybrids actually weaken genetically pure populations of disappearing wildlife?” What does “genetically pure” mean in a […]
“Here be dragons”
I just stumbled onto two amusing articles, Ancient legends once walked among early humans?, and The discovery of material evidence of a distinct hominin lineage in Central Asia as recently as 30,000 years ago is no surprise. The second is a letter from a folklorist:
Sir, The discovery of material evidence of a distinct hominin lineage […]
Cuckoldry more common in past generations
We have some data that in fact older generations were more sexually promiscuous, contrary to the moral panic perpetually ascendant. As a follow up to my previous post, there is some scholarship which suggests that misattributed paternity rates have been declining. Recent decline in nonpaternity rates: a cross-temporal meta-analysis:
Nonpaternity (i.e., discrepant biological versus social fatherhood) […]
The paternity myth: the rarity of cuckoldry
An urban myth, often asserted with a wink & a nod in some circles, is that a very high proportion of children in Western countries are not raised by their biological father, and in fact are not aware that their putative biological father is not their real biological father. The numbers I see and hear […]
The returns on homogeneity
A few days ago on Twitter I wondered if economists had calculated the costs of the world having a diversity of languages, instead of one language. The logic is that unintelligibility naturally throws up barriers to communication, and the flow of ideas and labor. This is one reason why the European Union necessarily has less […]
America in 2050 may still be majority white
I have expressed some skepticism at the idea that in the year 2050 the United States of America will perceive itself as a majority-minority nation; that is, non-Hispanic whites will be be a minority. This projection is repeated and asserted so often that it’s a plausible background assumption when you’re making a model of the […]
Another perspective on Facebook
From Ruchira Paul, who analyzes her own friend network. One issue which I think is relevant is that many people have several Facebook accounts for several different purposes. It’s an interesting window into the psychology of different individuals, as some seem happy to go along with Facebook’s preference of a unitary identity, while others resist […]
Daily Data Dump – Friday
Subprime for Students – Why does so much federal money go to for-profit schools—and what happens when the system crashes? Steve Eisman, a Cassandra of the subprime meltdown in real estate, is now focused on the student loan & grant racket in the for-profit education industry. I have nothing against competition forcing the relatively static […]
The “how” of cystic fibrosis through the “why”
It’s just a fact that contemporary human evolutionary genetics has relied upon its potential insights into disease to generate funding, support and interest. I don’t think that this is much of a silver lining when set next to the suffering caused by disease, but it’s a silver lining nevertheless. Therefore findings which would be of […]
“What has bioinformatics done for us”
So asks Anthony Goldbloom: A British bioinformatician asks what bioinformatics has ever done for us? Or put differently, what is the single greatest biological discovery made possible by bioinformatics? He is offering $USD100 to the person who puts forward the most compelling answer (the prize is small but the idea is to stoke discussion). Kaggle […]
