I published the first survey of national and racial differences in intelligence worldwide (Lynn, 1978) [16]. In this, I set the British IQ at 100 with a standard deviation of 15 and showed that the European peoples, including those in the United States, Australia and New Zealand, have same IQ, except for southern Europe, where the IQ was somewhat lower, falling to 89 in Greece. I gave the IQ in Iraq, Iran, India and sub-Saharan Africa as in the mid to low 80s; the IQ of Northeast Asians in Japan and Singapore as approximately 107; the IQ of Southeast Asians represented by Indonesia as 96; the IQ of Native American Indians as in the low 90s; the IQ of New Zealand Maori as approximately 94; the IQ of Micronesians and Polynesians as approximately 88; the IQ of Australian Aborigines as about 80; and the IQ of Kalahari Bushmen as approximately 55. These national and racial IQs have been largely confirmed by the numerous studies that have been published during the subsequent forty years that I have summarised in Lynn (2015) [17] and have been confirmed independently by David Becker in Lynn and Becker (2019) [18]. The only substantial differences are that the more recent data show the IQ of sub-Saharan Africans is approximately 70 and the IQ of Australian Aborigines is 62.
