Outline (back to top) Introduction How large are the IQ gains? Where is the IQ test data from? What are possible causes for the Flynn Effect? Why must IQ tests be constantly restandardized? Who has written about the Flynn Effect? Introduction (back to outline) In his study of IQ tests scores for different populations over the past sixty years, James R. How large are the IQ gains? Research shows that IQ gains have been mixed for different countries. Fluid Intelligence Crystallized Intelligence Where is the IQ test data from? What are possible causes for the Flynn Effect? What do intelligence tests really test?

Imitation of Life Can a computer program reproduce everything that happens inside a living cell? Brian Hayes Almost 30 years ago, Harold J. Morowitz, who was then at Yale, set forth a bold plan for molecular biology. The Tarahumaras: An Endangered Species : Mexico Culture & Arts Shep Lenchek Never conquered by the Aztecs and despite being defeated by Mexican armies, the Tarahumaras still consider themselves an independant nation. So strong is this conviction that in the Fifties they more than once took complaints directly to the United Nations. Perhaps the purest and most unmixed of any Indian tribe in Mexico, so little is known about them that their true name "Raramuri" was corrupted to "Tarahumara" by white men and never corrected. Most of the world knows them only as long distance runners.

Over half the world now live in cities according to UN Report July 12, 2007 A United Nations report coinciding with World Population Day reveals that for the first time in history, more people now live in cities than rural areas. There are now 6.6 billion of us – a figure expected to surge dramatically by 37 percent to 9.076 billion by the year 2050 according to the UN report, with Asia and Africa leading the growth. World Population Day on July 11 is aimed at focusing on efforts to turn the challenges of population growth into opportunities.

What If the 21st Century Begins in 2014? As if you didn’t already have enough to be nervous about, here’s something creepy to ponder as the new year opens. This what-if isn’t technological, social, political or even science-fictional. Rather, it’s a bit of wholly unscientific, superstitious pattern-recognition. The last two centuries (and possibly more) didn’t “start” at their official point, the turning of a calendar from 00 to 01. That wasn’t when they began in essence, nor when they first bent the arc of history. No.

How Science Changes - Rebecca J. Rosen An interview with Samuel Arbesman, author of The Half-Life of Facts Dim Dimich/Shutterstock/Rebecca J. Rosen In 1947 a mathematician named Derek J. de Solla Price came to Raffles College in Singapore to teach. He did not, Samuel Arbesman writes in his new book, "intend to spearhead an entirely new way of looking at science." But as you probably guessed, that's exactly what he did, or we would not be retelling his story here.

Researchers uncover 8,000 years of human history hidden in the Middle East Which would be interesting, seeing as, when interpreted literally, the Bible also claims that the universe was created between 6000-8000 years ago. Which is problematic, to say the least. EDIT: Not to mention the mental gymnastics required to reconcile the (presumably) carbon dating of the earliest Mesopotamian settlements to 8000 years ago and the fact that that same dating methods go on to describe artifacts and fossils that are up to 40 000 years old. As I recall, Asimov hypothesized that the age of creation used in the Bible is actually linked to the point at which we (or rather Near Eastern peoples) began recording history in the form of writing. Not sure how strong his evidence was but it sounds reasonable intuitively. That's always been the same assumption that I have made.

Think Again: War - By Joshua S. Goldstein "The World Is a More Violent Place Than It Used to Be." No way. The early 21st century seems awash in wars: the conflicts in Afghanistan and Iraq, street battles in Somalia, Islamist insurgencies in Pakistan, massacres in the Congo, genocidal campaigns in Sudan. Why 2012 was the best year ever Never in the history of the world has there been less hunger, less disease and more prosperity Has national morale ever been as strong as it was during the Jubilee and the Olympics? Photo: Getty Images. Books: None of the Above Correction appended. One Saturday in November of 1984, James Flynn, a social scientist at the University of Otago, in New Zealand, received a large package in the mail. It was from a colleague in Utrecht, and it contained the results of I.Q. tests given to two generations of Dutch eighteen-year-olds. When Flynn looked through the data, he found something puzzling.

Written in Bone - A Highly Unusual Case In 2002, archaeologists uncovered an isolated grave just outside the log wall of a fort built on an island in the James River almost four centuries earlier. Who was buried there? Male skeleton (burial partially re-created for an exhibition) 1607, James Fort site, Jamestown Virginia.
