![]() Smart people could be underscored and vice versa, depending on the conditions of the administration of the test or on the personality of the test-taker. Of course, that does not mean IQ tests are perfect and always produce perfect scores. Indeed, both statistics are assessed during the construction process of the IQ test. ![]() So, in sum, IQ tests are both valid and reliable they measure intelligence in a consistent way and the scores that they produce correlate with real-life outcomes, with those related to the construct of intelligence. If they were not, if both variables turned out to be uncorrelated, then that would mean that there is something wrong with the IQ test under assessment. ![]() If, for instance, smarter people are better in the academic realm, then that means that those who score higher on a given IQ test should also be better academically. If these correlations are found, and these real-life outcomes are variables that fit within the definition of the construct being measured, that means the test is valid.įor instance, we would expect people who score high on IQ tests to exhibit results in a life that “intelligent” people are supposed to have. Another way to infer the validity of a test is to find correlations between the results of the test and real-life outcomes.
