When genes matter for intelligence
Image credit: Aleksandra Pospiech One of the interesting and robust nuggets from behavior genetics is that heritability of psychological traits increases as one ages. Imagine for example you have a cohort of individuals you follow over their lives. At the age of 1 the heritability of I.Q. may be ~20%. This means that ~20% of […]
Kissing & the science of humanity
I approached Sheril Kirshenbaum’s The Science of Kissing: What Our Lips Are Telling Us with some trepidation and excitement. The former is a consequence of my hypochondria and its associated germophobia. I have no aversion to kissing in my own life (apologies for divulging personal information), but I did have some worries about having to […]
The Human Nature Top 10
A few days Kevin Drum proposed a “Human Nature Top 10.” Here are the criteria:
Not personal pet theories, but aspects of human nature that are (a) widely accepted and relatively noncontroversial among professionals, and (b) underappreciated by most of us. They can come from anywhere: economics, psychology, sociology, politics, anthropology, whatever.
He offers two: loss aversion […]
American family values: where even the dull can dream!
One of the issues when talking about the effect of environment and genes on behavioral and social outcomes is that the entanglements are so complicated. People of various political and ideological commitments tend to see the complications as problems for the other side, and yet are often supremely confident of the likely efficacy of their […]
The illusions of intuition
Sometimes books advertise themselves very well with their title. The Invisible Gorilla: And Other Ways Our Intuitions Deceive Us is one of those books. Alternatively it could have been titled: “Giving thinking a second chance.” Or, with an eye toward pushing copies: “Why everything Malcolm Gladwell tells you is crap.” And finally, a more highbrow […]

Harvard University psychologist Marc Hauser — a well-known scientist and author of the book “Moral Minds’’ — is taking a year-long leave after a lengthy internal investigation found evidence of scientific misconduct in his laboratory.

Porn and moral panic
Social conservative blogger Rod Dreher points me to this interview of a Left-wing sociologist on the malevolent influence of pornography on modern relationships. She has a book out, Pornland: How Porn has Hijacked our Sexuality. Her conclusion:
To turn this around there needs to be a massive public health awareness campaign. Unless people begin to understand […]
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 […]
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 […]
Tickling
Did not know this:
Still, these platonic tickle sessions appear to be rare. Based on a survey he conducted for his fascinating book Laughter, neuroscientist Robert Provine notes that adults and adolescents are seven times more likely to be tickled by members of the opposite sex. When asked whom they would most like to be tickled […]
What era are our intuitions about elites and business adapted to?
Well, just the way I asked it, our gut feelings about the economically powerful are obviously not a product of hunter-gatherer life, given that such societies have minimal hierarchy, and so minimal disparities in power, material wealth, privileges of a…
Using your brain

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 of the […]
Why do we delay gratification even when there is no downside?
Earlier this year, John Tierney reviewed several studies on how delaying gratification makes us feel better in the short term by preventing guilt but makes us feel more miserable in the long term by causing regret over missed opportunities. I added my …
No support for birth order effects on personality from the GSS
In researching for a review of The Nurture Assumption, I read over the debate between Harris and Sulloway over birth order effects on personality. Sulloway’s thesis, explained in Born to Rebel, is that last-born children have more rebellious, agreeabl…
The Faith Instinct in National Review
John Derbyshire has review of The Faith Instinct up. He hits the major points well. I should elaborate on something. In Darwin’s Cathedral David Sloan Wilson outlines two dimensions of religion, the horizontal and the vertical. The vertical is pretty s…
A simple framework for thinking about cultural generations
In this discussion about pop music at Steve Sailer’s, the topic of generations came up, and it’s one where few of the people who talk about it have a good grasp of how things work. For example, the Wikipedia entry on generation notes that cultural gene…
