Document Summary
Iq scores should correlate with other indices of a person"s intellectual ability (predicts success in school and careers) Iq scores do correlate moderately well with: grades in school (r from 0. 30 -0. 70, employment in intellectually demanding occupations, but, r between iq and employment could be due to r between iq and school performance. R of iq with on-the-job performance: moderate positive correlations, best predictors for performance on jobs involving high mental complexity. Iq at age 11 significantly higher likelihood of being alive at age 76: better self-care. Found that people who scored high on one test also scored high on all other tests. Some common factor is measured by every mental test. General intelligence (g): the underlying ability that contributes to a person"s performance on all mental tests (best measures of g come from averaging the scores on many diverse mental tests) Agreed with spearman that scores on mental tests reflect general intelligence.
