TwoSTDVs on height and sex

OneSTDV (who I'm a huge fan of) believes he has identified an indisputable fact of gender realism, that women rarely date men who are shorter than they are.The problem with this assertion is that in the US, the average height is 5'10" for men and 5'4" for women'. Contemporary measures of standard deviations for American height vary a bit, from about 2.5 inches to 3 inches. For the sake of argument, we'll error on the high end and call it 3 full inches....

Tracing the growth of "Judeo Christian"

Reacting to Lawrence Auster's visceral reactions towards anyone on the right who is not viewed as sufficiently supportive of Israel, Dennis Mangan remarks that it was not so-called "Judeo-Christian" morality that shaped Western civilization, but simply Christian morality that did.While Dennis' assertion would have gone undisputed in the fifties when he was a toddling around,...

On the passive suggestion of Parapundit's Randall Parker, I'm reading The World Without Us, a book by Alan Weisman that attempts to describe the future following the abrupt extinction of homo sapiens. It immediately strikes me as disappointingly misanthropic and distractingly quasi-religious (what Half Sigma terms "Gaia worship"). The recurring criticisms I have with this approach--the idea that humans have somehow unfairly intruded onto evolution's...

Mark Wethmen, who formerly blogged at Congenial Times (since deleted and then reincarnated, though not obviously related to its previous life), graciously sent me data from the Arizona Department of Health Services showing birth trends by race in the state over the last decade. Consequently, I'm going to take one more shot from the fecundity elixir, and then I'll really put...

Of chimps and men

When I came across the video below (not for the squeamish) via OneSTDV, the following passage from Nick Wade's Before the Dawn sprung to mind (p148-9):Chimp warfare takes the form of bands of males who patrol the borders of their territory, looking for an individual of the neighboring community who has been rash enough to feed alone. ...Chimpanzees carefully calculate the odds and seek to minimize risk, a very necessary procedure if one fights on...

... which, given that they top the list among states in the worst financial shape in the country, isn't too comforting. What I'm referring to here, though, is racial composition, exclusively. The following table* ranks each state by its racial disparities with the US on the whole:StateVariance1. Illinois4.12. New Jersey10.33. New York13.44. Connecticut15.75. Florida17.26. Virginia17.97.

Devon's doing less of it now, too

After this, I'm off the fecundity kick for awhile, promise. In the following graph, GSS respondents are broken up into five categories; Really Smarts (wordsum score of 9-10, comprising 13% of the population), Pretty Smarts (7-8, 26%), Normals (6, 22%), Pretty Dumbs (4-5, 27%), and Really Dumbs (0-3, 12%). The average number of children middle-aged adults in each category...

Calling BS on Timothy Geithner

A few weeks ago, Timothy Geithner was interviewed by NPR's Robert Siegel ahead of a "working dinner" between the US Treasury Secretary and the Chinese vice premier concerning currency policies and intellectual property. In response to a question from Siegel about how responsible the putative undervaluation of the yuan is for the ongoing US trade deficit with China, Geithner offered this response:Well, the big reason we have a trade imbalance in China...

Educational attainment and barrenness in the US

In the comments of a previous post on the relationship between fecundity and educational attainment in the US, Bruce Charlton wondered what percentage of women never had children by educational category, noting that in Europe around one-third of female college graduates are barren.Fertility in the US is higher than that among those with bachelor's degrees, but at the doctoral level, nearly one in three women never get around to starting a family....

Classical music and double-digit IQs

Steve Sailer recently reiterated an observation made by Linda Gottfredson that perhaps the surest way to assess a person's IQ from casual conversation without risking a false positive is by asking the person whether or not he likes classical music. If the answer is "yes", his IQ is in the triple-digits. If he doesn't enjoy it, though, his answer is less suggestive.The brief post's comment thread is pretty heated but largely anecdotal, so let's turn...

With the Superbowl a day away, here are correlations between several favorite stats and wins during the 2010 NFL regular season.

Income relative to IQ, by occupation

++Addition++Steve Sailer adds some flavor, pulling from his personal experience in a marketing research firm.---With occupational average IQ estimates constructed from median income and, separately, from wordsum scores, the question of which occupations garner earnings higher than the IQ of their practitioners would predict, and which occupations bring in less than IQ would predict, naturally arises. The following table ranks occupations by the income...
