Argues that a significant part of the gap between rich and poor countries is due to differences in national intelligence.

A scientific response to the best-selling The Bell Curve which set off a hailstorm of controversy upon its publication in 1994. Much of the public reaction to the book was polemic and failed to analyse the details of the science and validity of the statistical arguments underlying the books conclusion. Here, at last, social scientists and statisticians reply to The Bell Curve and its conclusions about IQ, genetics and social outcomes.

Most Americans strongly favor equality of opportunity if not outcome, but many are weary of poverty's seeming immunity to public policy. This helps to explain the recent attention paid to cultural and genetic explanations of persistent poverty, including claims that economic inequality is a function of intellectual ability, as well as more subtle depictions of the United States as a meritocracy where barriers to achievement are personal--either voluntary or inherited--rather than systemic. This volume of original essays by luminaries in the economic, social, and biological sciences, however, confirms mounting evidence that the connection between intelligence and inequality is surprisingly weak and demonstrates that targeted educational and economic reforms can reduce the income gap and improve the country's aggregate productivity and economic well-being. It also offers a novel agenda of equal access to valuable associations. Amartya Sen, John Roemer, Robert M. Hauser, Glenn Loury, Orley Ashenfelter, and others sift and analyze the latest arguments and quantitative findings on equality in order to explain how merit is and should be defined, how economic rewards are distributed, and how patterns of economic success persist across generations. Moving well beyond exploration, they draw specific conclusions that are bold yet empirically grounded, finding that schooling improves occupational success in ways unrelated to cognitive ability, that IQ is not a strong independent predictor of economic success, and that people's associations--their neighborhoods, working groups, and other social ties--significantly explain many of the poverty traps we observe. The optimistic message of this beautifully edited book is that important violations of equality of opportunity do exist but can be attenuated by policies that will serve the general economy. Policy makers will read with interest concrete suggestions for crafting economically beneficial anti-discrimination measures, enhancing educational and associational opportunity, and centering economic reforms in community-based institutions. Here is an example of some of our most brilliant social thinkers using the most advanced techniques that their disciplines have to offer to tackle an issue of great social importance.

Over the last few decades, economists and psychologists have quietly documented the many ways in which a person's IQ matters. But, research suggests that a nation's IQ matters so much more. As Garett Jones argues in Hive Mind, modest differences in national IQ can explain most cross-country inequalities. Whereas IQ scores do a moderately good job of predicting individual wages, information processing power, and brain size, a country's average score is a much stronger bellwether of its overall prosperity. Drawing on an expansive array of research from psychology, economics, management, and political science, Jones argues that intelligence and cognitive skill are significantly more important on a national level than on an individual one because they have "positive spillovers." On average, people who do better on standardized tests are more patient, more cooperative, and have better memories. As a result, these qualities—and others necessary to take on the complexity of a modern economy—become more prevalent in a society as national test scores rise. What's more, when we are surrounded by slightly more patient, informed, and cooperative neighbors we take on these qualities a bit more ourselves. In other words, the worker bees in every nation create a "hive mind" with a power all its own. Once the hive is established, each individual has only a tiny impact on his or her own life. Jones makes the case that, through better nutrition and schooling, we can raise IQ, thereby fostering higher savings rates, more productive teams, and more effective bureaucracies. After demonstrating how test scores that matter little for individuals can mean a world of difference for nations, the book leaves readers with policy-oriented conclusions and hopeful speculation: Whether we lift up the bottom through changing the nature of work, institutional improvements, or freer immigration, it is possible that this period of massive global inequality will be a short season by the standards of human history if we raise our global IQ.

Using data from the National longitudinal Study of Youth, argues that intelligence quotient has an important effect on income independent of family background.

Emotional intelligence is an important trait for success at work. IQ tests are biased against minorities. Every child is gifted. Preschool makes children smarter. Western understandings of intelligence are inappropriate for other cultures. These are some of the statements about intelligence that are common in the media and in popular culture. But none of them are true. In the Know is a tour of the most common incorrect beliefs about intelligence and IQ. Written in a fantastically engaging way, each chapter is dedicated to correcting a misconception and explains the real science behind intelligence. Controversies related to IQ will wither away in the face of the facts, leaving readers with a clear understanding about the truth of intelligence.
