Excerpt from the conclusion written by Charles Murray, AEI.2009
We have reviewed overwhelming evidence that genetic and hormonal differences between males and females are major causes of sex differences in 258 THE SCIENCE ON WOMEN AND SCIENCE behavior. These include differences in social behaviors in infants, play behaviors, interests, activities, educational and vocational goals, choices of occupations, patterns of cognitive abilities, and the frequency of extreme giftedness in spatial, mechanical, and mathematical ability. The dominance of female doctoral students in the life and human sciences and of male doctoral students in the inorganic sciences and engineering is consistent with and predictable by sex differences in interests and ability patterns. The greater social interest and ability of females than males is evident in infancy. The differing play activities and interests of boys and girls share similarities with sex differences in the play behaviors of nonhuman primates. Interests, activities, values, and vocational goals that differentiate girls from boys and women from men are strongly affected by the level of fetal androgen exposure or tissue sensitivity to androgen. Daily, monthly, or yearly cycles in levels of adult sex hormones influence performance on certain verbal and spatial tasks

For a British boy to be killed by a grenade attack anywhere is appalling, but for it to happen in a suburb of Gothenburg should shatter a few illusions about Sweden. Last week’s murder of eight-year-old Yuusuf Warsame fits a pattern that Swedes have come slowly to recognise over the years. He was from Birmingham, visiting relatives, and was caught up in what Swedish police believe is a gang war within the Somali community. Last year, a four-year-old girl was killed by a car bomb outside Gothenburg, another apparent victim of gang violence.
Fraser Nelson and Ivar Arpi discuss the Swedish model for migration on this week’s Spectator podcast:
For years, Sweden has regarded itself as a ‘humanitarian superpower’ — making its mark on the world not by fighting wars but by offering shelter to war’s victims. Refugees have arrived here in extraordinary numbers. Over the past 15 years, some 650,000 asylum-seekers made their way to Sweden. Of the 163,000 who arrived last year, 32,000 were granted asylum. Sweden accepts more refugees in proportion to size of population than any other nation in the developed world — when it comes to offering shelter, no one does it better. But when it comes to integrating those we take in (or finding the extra housing, schools and healthcare needed for them), we don’t do so well.

Guns, Gangs, and Genes: Evidence of an Underlying Genetic Influence on Gang Involvement and Carrying a Handgun
Gangs and guns represent two key sources of violence in America and around the world. While a considerable amount of research has been devoted to studying each outcome, neither has been extensively studied from a biosocial perspective. The current study addressed this gap in the literature by estimating the genetic and environmental underpinnings to gang membership, carrying a handgun, and the covariance between the two. Analyses of kinship pairs from the NLSY97 data revealed significant genetic influences on all of them. Specifically, genetic factors explained 77% of the variance in gang membership, 27% of the variance in carrying a handgun, and 66% of the covariance between gang membership and carrying a handgun. Just as important, however, is that the shared environment explained none of the variance/covariance across models, with all of the remaining variance being accounted for by nonshared environmental effects (plus error).
