Drawing on the latest research in psychology and neuroscience, this groundbreaking study examines the role that personality traits play in determining intelligence test performance. The author's insightful analysis sheds new light on how we measure intelligence and the factors that contribute to it.

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.

However, Jensen does not draw back from its most controversial conclusions - that the average differences in IQ and other abilities found between sexes and racial groups have a substantial hereditary component, and that these differences have important societal consequences.

This is a unique work which is the culmination of the author's many years of experience in the use of the Wechsler tests in clinical assessments and as a teacher of their use. In his research, he has questioned the validity of the hypotheses used to explain the meaning of Wechsler data and the heuristic value of Wechsler data in clinical assessment. This book traces the history and development of the tests and reflects on their psychometric qualities and clinical utility. A challenging work, it asks clinicians to examine some of their most cherished hypotheses regarding the use of these tests in clinical assessment.
