Quizplus · Accepted Answer

Mack's method of measuring intelligence by using the circumference of a subject's forehead may be consistent or reliable in the sense that it could yield the same measurement each time the procedure is repeated on the same subject. However, this does not mean it is an accurate or valid measure of intelligence, as there is no established correlation between head size and intelligence.
