Just mention IQ testing in polite company, and you'll sternly be informed that IQ tests don't measure anything "real", and only reflect how good you are at doing IQ tests; that they ignore important traits like "emotional intelligence" and "multiple intelligences"; and that those who are interested in IQ testing must be elitists, or maybe something more sinister.Yet the scientific evidence is clear: IQ tests are extraordinarily useful. IQ scores are related to a huge variety of important life outcomes like educational success, income, and even life expectancy, and biological studies have shown they are genetically influenced and linked to measures of the brain. Studies of intelligence and IQ are regularly published in the world's top scientific journals.This book will offer an entertaining introduction to the state of the art in intelligence and IQ, and will show how we have arrived at what we know from a century's research. It will engage head-on with many of the criticisms of IQ testing by describing the latest high-quality scientific research, but will not be a simple point-by-point rebuttal: it will make a positive case for IQ research, focusing on the potential benefits for society that a better understanding of intelligence can bring.

    His most recent book, God Is Not Great, was on the New York Times bestseller list in 2007 for months. Like his hero, George Orwell, Hitchens is a tireless opponent of all forms of cruelty, ideological dogma, religious superstition and intellectual obfuscation. Once a socialist, he now refers to himself as an unaffiliated radical. As a thinker, Hitchens is perhaps best viewed as post-ideological, in that his intellectual sources and solidarities are strikingly various (he is an admirer of both Leon Trotsky and Kingsley Amis) and cannot be located easily at any one point on the ideological spectrum. Since leaving Britain for the United States in 1981, Hitchens thinking has moved in what some see as contradictory directions, but he remains an unapologetic and passionate defender of the Enlightenment values of secularism, democracy, free expression, and scientific inquiry.The global turmoil of the recent past has provoked intense dispute and division among intellectuals, academics, and other commentators. Hitchens writing during this time, particularly after 9/11, is an essential reference point for understanding the genesis and meaning of that turmoil#151;and the challenges that accompany it. This volume brings together Hitchens most incisive reflections on the war on terror, the war in Iraq, and the state of the contemporary Left. It also includes a selection of critical commentaries on his work from his former leftist comrades, a set of exchanges between Hitchens and various left-leaning interlocutors (such as Studs Terkel, Norman Finkelstein, and Michael Kazin), and an introductory essay by the editors on the nature and significance of Hitchens contribution to the world of ideas and public debate. In response, Hitchens provides an original afterword, written for this collection.p pWhatever readers might think about Hitchens, he remains an intellectual force to be reckoned with. And there is no better place to encounter his current thinking than in this provocative volume.

    Coming eighteen years after the publication of The Ants, this new volume expands our knowledge of the social insects (among them, ants, bees, wasps, and termites) and is based on remarkable research conducted mostly within the last two decades. These superorganisms—a tightly knit colony of individuals, formed by altruistic cooperation, complex communication, and division of labor—represent one of the basic stages of biological organization, midway between the organism and the entire species. The study of the superorganism, as the authors demonstrate, has led to important advances in our understanding of how the transitions between such levels have occurred in evolution and how life as a whole has progressed from simple to complex forms. Ultimately, this book provides a deep look into a part of the living world hitherto glimpsed by only a very few.
