Aren IQ tests only good for predicting academic performance?
A. Then why have the U.S. armed forces invested heavily in IQ testing all potential recruits since WWII? Because the military has found, over and over again, that IQ correlates with performance in a huge array of military duties. Over a time, a unit with an average IQ of 110 is going to repair jet engines faster and accidentally shoot themselves in the foot less often than a unit with an average IQ of 90. Q. The military uses IQ tests? I never heard of such a thing! A. They don’t go out of their way to publicize it because it’s politically incorrect, but the Armed Forces Qualification Test, which is the central core of the larger ASVAB test, is required of everyone who wants to enlist. It’s the equivalent of a highly g-loaded IQ test. During the golden age of recruiting from 1992-2004, only 1 percent of enlistees got in with scores in the bottom 30 percent on the test (92 IQ or lower).
