The Intelligence of Nations

"Richard Lynn and David Becker have done an excellent job in updating IQs for all nations in the world showing that they range from an average of 69 in sub-Saharan Africa to 105 in Northeast Asia. In addition, they summarize studies of the genetic and climatic causes of these IQ differences and also of their numerous educational, economic, sociological and demographic effects. They conclude by discussing the future of national IQs and argue that dysgenic fertility and immigration will reduce intelligence in the United States and Europe, leaving China to emerge as the world super-power in the second half of the twenty-first century." Professor Helmuth Nyborg, University of Aarhus, Denmark "This update of IQs for 128 nations of the world and their causes and consequences will be welcomed by everyone interested in intelligence as a unifying construct for the social sciences." Professor Heiner Rindermann, University of Chemnitz, Germany
