Schmidt Quoted on Intelligence Tests

A story about the study of "emotional intelligence" says that contrary to common perception, traditional tests of general mental ability (GMA) or IQ do not measure some single, fixed genetic aptitude. They measure a variety of mental skills, as well as the ability to learn -- qualities that are partly linked to genes. These generally include numeric ability, verbal fluency and spatial aptitude (the ability to rotate and visualize objects mentally). Each of these skills functions differently in each individual: A mechanic may have sublime spatial skills but limited numeric ability, and vice versa for an accountant. But the idea is that by measuring several things at once you detect an intelligence that shares all three, said FRANK SCHMIDT, an industrial psychologist who studies intelligence testing at the University of Iowa.
