Does your family make you smarter? Environmental inheritance and the limits of human independence

Only a few researchers could honestly deal with the surrounding issues of causes and effects related to the intelligence trait, and fewer of those could delve into this field with the originality and clarity that characterized Flynn. Steven Pinker (Department of Psychology, Harvard University). Another tremendous effort from the best mind in this field. A keen insight in data analysis, and insightful explanations, as the presented theories of intelligence are a rich meal for the mind. Thomas G. Bouchard Jr., recipient of the Dvorsky Award for Academic Excellence in Behavioral Genetics. Another excellent analysis of intelligence test data by Flynn! As the author of the fifth edition of the Stanford-Binet Intelligence Test, I have always been impressed by Flynn's work. I highly recommend this book, which sheds new light on intelligence across different age stages. Guil H. Roid (author of the fifth edition of the Stanford-Binet Intelligence Test).
