Chapter 11: Intelligence Required characteristics for a good test:    Validity: the test must measure what it is supposed to measure.       Concurrent validity: the test must reflect your current state/level.       Predictive validity: the test must reflect your future performance.    Reliability: the test must give very similar results each time you take the same test.    Standardization: many people have to take the test; their distribution tells you the average score for the entire population as well as the percentage of people who scored higher/lower than you.       The test is only valid for populations on which it was standardized! Intelligence tests mostly assess analytic intelligence.    Like many aptitude tests they are good at predicting academic success, but poor at everything else.       Intelligence tests are now mostly used to detect people who may be mentally retarded, or who have serious psychological disorders.       Intelligence tests are negatively biased toward the groups they were not standardized on.
