Students of the problem of sex differences in intelligence will be indebted to Mackintosh and Flynn for providing useful further clarification of the issue of sex differences in intelligence. I have little to say about Flynn's paper except to note that it confirms my thesis that among adults males have a small advantage over females in abstract reasoning ability. Mackintosh and I have some common ground but there remain substantial disagreements.
