Psychometricians have discovered a trend showing that IQ scores in children have shown a significant rise over the past 50 years, and scores between white and minority students are converging. This trend, dubbed the Flynn Effect after James Flynn, the social scientist who first documented it, is the focus of this book. Is it possible to compare IQ scores from one generation to the next? Which environmental factors most affect IQ? What kind of intelligence does psychometric tests actually measure? Leading experts in nutrition, psychometric research, sociology and cognitive, social and developmental psychology debate the source of the Flynn Effect, along with the much-discussed dysgenic hypothesis, made popular by Charles Murray in The Bell Curve. This should be useful to those who seek the latest scholarship on intelligence and its measure.
Do we have the wrong map for the Christian life? Life's inconveniences, disappointments, and trials can leave us confused, cynical, and eventually bitter. But the apostle Paul traces out the path of dying and rising with Jesus—what Paul Miller calls the “J-Curve”—as the normal Christian life. The J-Curve maps the ups and downs of daily life onto the story of Jesus. It grounds our journeys not in some abstract idea but in union with Christ and his work of love. Understanding our lives in light of the J-Curve roots our hope, centers our love, and tethers our faith to Christ.
In 1958, Charles David Keeling began measuring the concentration of carbon dioxide in the earth's atmosphere at the Mauna Loa Observatory in Hawaii. His project kicked off a half century of research that has expanded our knowledge of climate change. Despite more than fifty years of research, however, our global society has yet to find real solutions to the problem of global warming. Why? In Behind the Curve, Joshua Howe attempts to answer this question. He explores the history of global warming from its roots as a scientific curiosity to its place at the center of international environmental politics. The book follows the story of rising CO2—illustrated by the now famous Keeling Curve—through a number of historical contexts, highlighting the relationships among scientists, environmentalists, and politicians as those relationships changed over time. The nature of the problem itself, Howe explains, has privileged scientists as the primary spokespeople for the global climate. But while the “science first” forms of advocacy they developed to fight global warming produced more and better science, the primacy of science in global warming politics has failed to produce meaningful results. In fact, an often exclusive focus on science has left advocates for change vulnerable to political opposition and has limited much of the discussion to debates about the science itself. As a result, while we know much more about global warming than we did fifty years ago, CO2 continues to rise. In 1958, Keeling first measured CO2 at around 315 parts per million; by 2013, global CO2 had soared to 400 ppm. The problem is not getting better - it's getting worse. Behind the Curve offers a critical and levelheaded look at how we got here.
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.
