I stumbled on this relatively concise article that provides a nice (and brief) overview of the historical “bad days” of IQ test and score misuse. Don’t let the title’s focus on epilepsy deter you from reading—the content is relevant to thinking about intelligence and IQ scores in general. After the succinct overview of the horrible historical uses of IQ tests and scores, the article touches on contemporary theories and thinking (e.g., process overlap theory or POT; CHC cognitive abilties theory) that view the IQ score as nothing more than a statistical emergent property index—and the need to focus on broad CHC abilities from cognitive ability tests.
