Peer reviewedSpitz, Herman H. – Intelligence, 1989
Studies involving groups administered the Wechsler Adult Intelligence Scale (WAIS) and the WAIS-Revised were examined to determine the validity of J. R. Flynn's (1987) findings of massive intelligence quotient gains in a single generation in many nations. Results for sampled adults support Flynn for the average intelligence range only. (TJH)
