Intelligence Genes And Success

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.

A provocative and timely case for how the science of genetics can help create a more just and equal society In recent years, scientists like Kathryn Paige Harden have shown that DNA makes us different, in our personalities and in our health—and in ways that matter for educational and economic success in our current society. In The Genetic Lottery, Harden introduces readers to the latest genetic science, dismantling dangerous ideas about racial superiority and challenging us to grapple with what equality really means in a world where people are born different. Weaving together personal stories with scientific evidence, Harden shows why our refusal to recognize the power of DNA perpetuates the myth of meritocracy, and argues that we must acknowledge the role of genetic luck if we are ever to create a fair society. Reclaiming genetic science from the legacy of eugenics, this groundbreaking book offers a bold new vision of society where everyone thrives, regardless of how one fares in the genetic lottery.

G is for Genes shows how a dialogue between geneticists and educationalists can have beneficial results for the education of all children—and can also benefit schools, teachers, and society at large. Draws on behavioral genetic research from around the world, including the UK-based Twins’ Early Development Study (TEDS), one of the largest twin studies in the world Offers a unique viewpoint by bringing together genetics and education, disciplines with a historically difficult relationship Shows that genetic influence is not the same as genetic determinism and that the environment matters at least as much as genes Designed to spark a public debate about what naturally-occurring individual differences mean for education and equality

The "nature versus nurture" controversy dates back to at least the nineteenth century. How much of a role does genetics or environment play in accounting for reasoning skill and other intellectual aptitudes? At a time when the public school system in the United States is under attack, this debate has taken center stage in arguments about what accounts for differences in academic achievement. Maximizing Intelligence convincingly argues that, while both genetics and environment play a role in a child's intelligence, environmental factors, especially at an early age, are of primary importance. Working from this premise, Armor suggests how intelligence may be heightened. Armor presents four propositions about intelligence. His first is that intelligence exerts a major influence on educational and occupational success, following a chronological sequence, from a child's cognitive skills learned before school, to academic success during the school years, to eligibility for college. His second proposition is that intelligence can be changed, at least within limits. There is ample evidence that a child's intelligence is not fully given at birth, but continues to evolve and change at least through the early elementary school years, although at a declining rate. Proposition three is that intelligence is influenced by a series of "risk factors," and most of the influence occurs before a child reaches school age. Risk factors include parent intelligence and education, family income, family structure and size, nutrition, and specific parenting behaviors. The fourth proposition flows from the second and third--that the most promising avenues for maximizing intelligence come from a child's parents. Armor persuasively argues for a "whole family" approach whereby government programs are modified or created to inform parents of risk factors and to reward behaviors that optimize positive outcomes. Maximizing Intelligence is meticulously researched

"Fresh insights into the nature of exceptional peformance…. A deeply interesting and important book” (New York Times Book Review) that offers a revolutionary and life-changing message on the new science of human potential. Is true greatness obtainable from everyday means and everyday genes? Conventional wisdom says no, that a lucky few are simply born with certain gifts. Now you can forget everything you think you know about genes, talent, and intelligence, and take a look at the amazing new evidence. Here, interweaving cutting-edge research from numerous scientific fields, David Shenk offers a new view of human potential, giving readers more of a sense of ownership over their accomplishments, and freeing parents from the bonds of genetic determinism. As Shenk points out, our genes are not a “blueprint” that dictate individual destinies. Rather we are all the product of interplay between genes and outside stimuli—a dynamic that we can influence. It is a revolutionary and life-changing message.

Written by James R. Flynn of the "Flynn effect" (the sustained and substantial increase in intelligence test scores across the world over many decades), Intelligence and Human Progress examines genes and human achievement in all aspects, including what genes allow and forbid in terms of personal life history, the cognitive progress of humanity, the moral progress of humanity, and the cross-fertilization of the two. This book presents a new method for weighing family influences versus genes in the cognitive abilities of individuals, and counters the arguments of those who dismiss gains in IQ as true cognitive gains. It ranges over topics including: how family can handicap those taking the SAT; new IQ thresholds for occupations that show elite occupations are within reach of the average American; what Pol Pot did to the genetic potential of Cambodia; why dysgenics (the deterioration of human genes over the generations) is important, but no menace for the foreseeable future; and what might derail human intellectual progress. Researchers in developmental and cognitive psychology, educators, and professionals involved in intelligence testing or psychometrics will benefit from the perspectives offered here. But beyond that, anyone interested in the potential of the human mind will be engaged and challenged by one of the most important contemporary thinkers on the subject.

There is a strange disconnect between the scientific consensus and the public mind on intelligence testing. 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.

The concept and measurement of intelligence present a curious paradox. On the one hand, scientists, fluent in the complex statistics of intelligence-testing theories, devote their lives to exploration of cognitive abilities. On the other hand, the media, and inexpert, cross-disciplinary scientists decry the effort as socially divisive and useless in practice. In the past decade, our understanding of testing has radically changed. Better selected samples have extended evidence on the role of heredity and environment in intelligence. There is new evidence on biology and behavior. Advances in molecular genetics have enabled us to discover DMA markers which can identify and isolate a gene for simple genetic traits, paving the way for the study of multiple gene traits, such as intelligence. Hans Eysenck believes these recent developments approximate a general paradigm which could form the basis for future research. He explores the many special abilities verbal, numerical, visuo-spatial memory that contribute to our cognitive behavior. He examines pathbreaking work on "multiple" intelligence, and the notion of "social" or "practical" intelligence and considers whether these new ideas have any scientific meaning. Eysenck also includes a study of creativity and intuition as well as the production of works of art and science identifying special factors that interact with general intelligence to produce predictable effects in the actual world. The work that Hans Eysenck has put together over the last fifty years in research into individual differences constitutes most of what anyone means by the structure and biological basis of personality and intelligence. A giant in the field of psychology, Eysenck almost single-handedly restructured and reordered his profession. Intelligence is Eysenck's final book and the third in a series of his works from Transaction.
