Divergent Validity

In psychological testing, Divergent Validity is used to determine if a test is too similar to another test. If a test is found to correlate too strongly (or be too similar) with another test then it suggests that the tests are measuring the same thing and are too alike to be considered different. An example would be a test used by a company for hiring purposes that measures how proficient someone is at a particular skill. If the test correlates too strongly with an IQ test then it essentially is just another IQ test instead of measuring something different.
