'What is intelligence?' may seem like a simple question to answer, but the study and measurement of human intelligence is one of the most controversial subjects in psychology. IQ and Human Intelligence provides an authoritative overview of the main issues surrounding this fascinating area.

Since the turn of the century, the idea that intellectual capacity is fixed has been generally accepted. But increasingly, psychologists, educators, and others have come to challenge this premise. Outsmarting IQ reveals how earlier discoveries about IQ, together with recent research, show that intelligence is not genetically fixed. Intelligence can be taught. David Perkins, renowned for his research on thinking, learning, and education, identifies three distinct kinds of intelligence: the fixed neurological intelligence linked to IQ tests; the specialized knowledge and experience that individuals acquire over time; and reflective intelligence, the ability to become aware of one's mental habits and transcend limited patterns of thinking. Although all of these forms of intelligence function simultaneously, it is reflective intelligence, Perkins shows, that affords the best opportunity to amplify human intellect. This is the kind of intelligence that helps us to make wise personal decisions, solve challenging technical problems, find creative ideas, and learn complex topics in mathematics, the sciences, management, and other areas. It is the kind of intelligence most needed in an increasingly competitive and complicated world. Using his own pathbreaking research at Harvard and a rich array of other sources, Perkins paints a compelling picture of the skills and attitudes underlying learnable intelligence. He identifies typical pitfalls in multiple perspectives, and neglecting evidence. He reveals the underlying mechanisms of intelligent behavior. And he explores new frontiers in the development of intelligence in education, business, and other settings. This book will be of interest to people who have a personal or professional stake in increasing their intellectual skills, to those who look toward better education and a more thoughtful society, and not least to those who follow today's heated debates about the nature of intelligence.

Lynn and Vanhanen test the hypothesis on the causal relationship between the average national intelligence (IQ) and the gap between rich and poor countries by empirical evidence. Based on an extensive survey of national IQ tests, the results of their work challenge the previous theories of economic development and provide a new basis to evaluate the prospects of economic development throughout the world. They begin by reviewing and evaluating some major previous theories. The concept of intelligence is then described and intelligence quotient (IQ) introduced. Next they show that intelligence is a significant determinant of earnings within nations, and they connect intelligence with various economic and social phenomena. The sociology of intelligence at the level of sub-populations in nations is examined, and the independent (national IQ) and dependent (various measures of per capita income and economic growth rates) variables are defined and described. They then provide empirical analyses starting from the 81 countries for which direct evidence of national IQs is available; the analysis is then extended to the world group of 185 countries. The hypothesis is tested by the methods of correlation and regression analyses. The results of statistical analyses support the hypothesis strongly. The results of the analyses and various means to reduce the gap between rich and poor countries are discussed. A provocative analysis that all scholars, students, and researchers involved with economic development need to confront.

IQ tests, which measure our ability to retain information, are out-dated. In the digital era, the new IQ is not about retaining knowledge, but managing it.

“By languages, in all their facets, we can live in peace or go to war. We sing songs in harmony, or shout insults in anger. We experience connection or disconnection. We work together in peace or in pain. The choice is ours.”—Anna Kendall Every so often, we meet people with whom we find it difficult to communicate. For one reason or another, we don’t seem to be on the same wavelength—it’s as if we’re speaking different languages. It’s frustrating when we try to discuss something with them or understand their point of view. The late renowned management consultant Peter Drucker claimed that 80 percent of all management problems were the result of faulty communication. Poor communication also causes strife in many relationships. Fred and Anna Kendall set out to discover how different people prefer to communicate and what methods they use to do so. The result is the Kendalls’ Life Languages program, which has been used successfully by tens of thousands of people around the world. In Communication IQ, the Kendalls share information about three communication intelligence categories—kinetic/action, emotive/feeling, and cognitive/thinking—and the seven Life Languages—Mover, Doer, Influencer, Responder, Shaper, Producer, and Contemplator. Each Life Language has a filter through which one views life and communication, a need that provides feelings of acceptance and love when it’s met, a key character strength, a learning style, and other traits. The Kendalls’ goal is to empower people to learn how to use their Life Language to better communicate with others in their personal lives, their careers, and the world at large, while also gaining a greater self-awareness of their own strengths and passions.
