The `Flynn effect` refers to the massive increase in IQ test scores over the course of the twentieth century. Does it mean that each generation is more intelligent than the last? Does it suggest how each of us can enhance our own intelligence? Professor Flynn is finally ready to give his own views. He asks what intelligence really is and gives a surprising and illuminating answer. This expanded paperback edition includes three important new essays. The first contrasts the art of writing cognitive history with the science of measuring intelligence and reports new data. The second outlines how we might get a complete theory of intelligence, and the third details Flynn`s reservations about Gardner`s theory of multiple intelligences. A fascinating and unique book that bridges the gulf separating our minds from those of our ancestors a century ago, and makes an important contribution to our understanding of human intelligence.
• Expanded paperback edition of James R. Flynn’s acclaimed What Is Intelligence, which has sold over 6,500 copies world-wide • The style is simple and direct, yet even experts will find their understanding of intelligence enhanced • Boxes and figures make IQ trends easy to comprehend.

"It is not just the fascinating effect that makes the book special. It`s also Flynn`s style. There`s an unusual combination of clarity, wit, apposite allusion, and farsightedness in making connections and exploring unexpected consequences." (Ian Deary, Edinburgh University)
"A masterful book that will influence thinking about intelligence for many years to come." (Robert J. Sternberg, PsycCRITIQUES)
"In a brilliant interweaving of data and argument, Flynn calls into question fundamental assumptions about the nature of intelligence that have driven the field for the past century. There is something here for everyone to lose sleep over. His solution to the perplexing issues revolving around IQ gains over time will give the IQ Ayatollahs fits!" (S. J. Ceci, Cornell University)
