Even though women consistently receive better grades in math and science, men excel on math aptitude tests and are greatly overrepresented in the so-called hard sciences. The Mathematics of Sex explores why males are overrepresented in mathematically intensive professions such as physics, computer science, chemistry, mathematics, and engineering. Bringing together for the first time important research from such diverse fields as endocrinology, economics, sociology, education, genetics, and psychology, the authors show that two factors--the parenting choices women (but not men) have to make, and the tendency of bright women to choose people-oriented fields like medicine--largely account for the under-representation of women in the hard sciences. Further, research shows that biology itself--differences in hormones or brain organization--does not fully account for the problem. Compressing an enormous amount of information--over 400 studies--into a readable, engaging account suitable for parents, educators, and policymakers, this book advances the debate about women in science unlike any other book before it.

By linking a wide range of social and economic conditions, The State of Americans is a “thoughtful, compelling piece of work” that presents a comprehensive overview of American social trends (William J. Bennett, bestselling author). With previous publications about social problems dealing with one issue at a time, The State of Americans is the first book to bring together the demographic data on social trends, systematically examining the relationships among them. Readers will find evidence supporting the authors’ claims that it is impossible to determine where America is headed unless there is consideration of factors such as family structures and social attitudes and recognition of how they influence each other. The State of Americans is the perfect read for anyone looking to understand the interrelationships among social and economic conditions and how they can determine whether the nation is prospering or declining.

Ceci argues that traditional conceptions of intelligence ignore the role of society in shaping intelligence and underestimate the intelligence of non-Western societies. He puts forth a "bio-ecological" framework of individual differences in intellectual development that is intended to address some of the major deficiencies of extant theories of intelligence. The focus is on alternative interpretations of phenomena that emerge when implicit assumptions of intelligence researchers are challenged.
