The best way to measure the reliability of a test that claims to measure intelligence is to conduct a test-retest reliability study. This involves administering the same test to the same group of people at two different times and then correlating the scores from the two administrations. If the scores are highly correlated, then the test is considered reliable. This method helps to determine whether most people's scores are similar on a test and a retest, which indicates that the test is consistent and reliable over time.
