Question

Quizplus · Accepted Answer

The IQ test used in World War I was heavily biased towards certain cultural backgrounds and favored those who were more familiar with the type of questions being asked. As a result, many of the recruits who scored low on the test were not necessarily mentally deficient, but simply did not have the same cultural knowledge and experiences as those who were better able to navigate the test.
