presentations. Several pieces of indirect evidence suggest biocultural interpretations for encephalization (Beals 1987). First, expansion of the brain case has been greater than is explicable by the corresponding increase in body size. Second, average human relative endocranial volume (24.9 cm3 per kg of body weight) is more than twice that of apes. "Biophysical" variables like body surface area, thermoregulation, and cranial geometry fail to fully explain the changes observed for hominid data… Expand

Race and sex differences in head size and IQ
Abstract An analysis of IQ in relation to head size (and by inference, brain size) was performed on some 14,000 children and their full siblings, almost evenly divided by race (white and black) andExpand
Cognitive abilities amongst the Sámi population
Abstract We review and summarize the data contained in three studies on the IQ of Sami peoples. Their IQ is estimated as highly similar to that of Finns (100.8 vs. 101), but their verbal IQ is lowerExpand
The Intelligence of Nations and their Economic and Social Effects
Differences in intelligence among individuals explain a wide range of different life outcomes including educational attainment, intellectual achievement, earnings, health, fertility, socialExpand
ABO Phenotype and Morphology
The existence of naturally occurring blood-group antigens without obvious benefit to the individual having them is one of the more perplexing and widely investigated problems in biology. TheExpand
Cognitive function among the Ainu people
Abstract The Ainu are an ethnic minority in northern Japan. Their overall IQ was estimated to be somewhat below that of the Japanese (97.2) from the meta-analysis of mostly pre-war Japanese data (N =Expand
Race as Social Construct
It is often claimed that race is a social construct and that scientists studying race differences are disruptive racists. The recent April 2018 “Race Issue” of the widely distributed NationalExpand
Biology, Immigration, and Public Policy
This paper discusses recent scientific research that has shifted the terms of the debate about the respective roles of nature and nurture in shaping behavior. The research includes literature in theExpand
The Bell Curve: Intelligence and Class Structure in American Life
The Bell Curve is a book about differences in intellectual capacity among people and groups, and what those differences mean for America's future. Encapsulated, this is our story: For people at theExpand
Reminiscences of forty years of friendship with Hans Eysenck and collaboration on work on racial and national differences in personality and intelligence
Abstract This paper summarises the author's friendship and collaboration with Hans Eysenck over forty years with particular reference to their work on racial and national differences in personalityExpand


Climate and the evolution of brachycephalization.
Evidence supports the hypothesis of cold adaptation among "Classic" Neandertals and it is probable that a decrease of the cranial index occurs from the Middle to Upper Paleolithic, and during the Holocene, the index increases under all climatic conditions. Expand

Paralleled timing neurons can overcome the usual neural noise limitations via the law of large numbers, suggesting that enhanced throwing skill could have produced a strong selection pressure for any evolutionary trends that provided additional timing neurons. Expand
Winter Temperature as a Constraint to the Migration of Preindustrial Peoples
The dispersion of preindustrial peoples is strongly related to winter temperature in two surprising respects. Based on a classification of societies by language, we introduce a statistical model forExpand
