Implications of Deafness, Deprivation, and IQ for IQ Differences between Groups
The study of deafness helps illuminate the nature and causes of between-group differences in IQ. Deafness offers a powerful paradigm for testing environmental, genetic, and interactionist theories of IQ differences between groups. By examining the IQs of deaf people in the context of IQ differences between groups, theories can be tested, refined, clarified. As such, deafness offers a valuable, and heretofore underutilized, tool for understanding why different groups have different distributions of IQ.
