To deny the predictive validity of race at this level is nonscientific and unrealistic.

Blacks in the Caribbean, Britain, Canada and sub-Saharan Africa as well as in the United States have low IQ scores relative to whites.

Each race (or variety) is characterized by a more or less distinct combination of inherited morphological, behavioral, physiological traits.

Of course, individuals vary greatly within each racial group and should be treated as such.

The biological factors underlying race differences in sports have consequences for educational achievement, crime and sexual behavior.

Nonetheless, much has been learned by studying the statistical differences between the various human races.

The mean pattern of educational and economic achievement within multi-racial countries such as Canada and the United States has increasingly been found to prove valid internationally.
