ABSTRACT

This chapter describes the ultimate taboo—race differences in behavior. It describes a classic study of behavioral differences among puppies of four dog breeds. The chapter examines these issues: race, brain size, and intelligence; income inequality and intelligence; and the mean sub-Saharan African IQ of 70. It deals with morphological measurements such as height, head shape, cranial capacity, facial features, and weight, the nature-nurture issue is always open to debate. The most extensively documented research on race differences in behavior concerns the fifteen-point difference between the average IQs of white Americans and African Americans, whites being higher, but Asians have a slightly higher average IQ than do whites. The Freedmans decided to observe the behavior of newborns and infants of different races. The productive questions pertain to how races came to be and the extent to which racial variation has significant consequences with respect to function in the modern world.
