Is Psychometric g a Myth?
- "As an online discussion about IQ or general intelligence grows longer, the probability of someone linking to statistician Cosma Shalizi's essay g, a Statistical Myth

"Over the past few decades, 160 million women have vanished from East and South Asia
— or, to be more accurate, they were never born at all. Throughout the region, the practice of sex selection — prenatal sex screening followed by selective termination of pregnancies — has yielded a generation packed with boys. From a normal level of 105 boys to 100 girls, the ratio has shifted to 120, 150, and, in some cases, nearly 200 boys born for every 100 girls. In some countries, like South Korea, ratios spiked and are now returning to normal. But sex selection is on the rise in Eastern Europe, Southeast Asia, and the Middle East." American journalist Mara Hvistendahl's new book: "Unnatural Selection: Choosing Boys Over Girls, and the Consequences of a World Full of Men
," examines and tries to predict the actual and potential effects of unequal sex ratios on men, women and the social economies of the affected regions, including the recent spike in sex trafficking and bride-buying across Asia. More

Understanding what makes America tick
"The belief that America is exceptional, in the double sense that it is superior and that it is different...The United States had a mission, a manifest destiny, to change the world in its image. This conviction echoes down through American history....Other countries—France, Britain, Russia—have from time to time in their history felt a sense of mission, of carrying their civilisation to other peoples and territories. But in their cases it has been episodic and not deeply rooted—usually limited to when their power was at its zenith and usually clearly recognisable as a rationalisation for what they were doing for other reasons. In the case of the United States, it has been constant and central

Do we all need to get out more?
Although they're putting the "too much time with computers, not enough social interaction" spin on this study's findings, there are actually some good results of it. Heavy internet users spend less time in traffic (because they look up traffic
before going anywhere?), less time in malls (shopping online instead, duh), and less time watching TV (this is the best news of all, I barely watch it anymore because it's mostly inane garbage, whereas on the internet, I can find interesting things
). As for the less face time with friends and family, I have a growing number of friends online that I consider to be as close as any Real Life friend could be.
