But looking now at the broader picture, it is certainly useful to study specific populations: young versus old, tall versus short, Mediterranean versus Anglo-Saxon, Jewish versus Christian, high IQ versus low IQ, active versus inactive, men versus women, and black versus white or Asian. The questions are, How useful is this? and How should we spend precious and diminishing research dollars? When observed in these terms (and while we are being practical, focused, and thoughtful), doing gender-based studies is generally unwarranted, with important exceptions. Far more vital concerns draw our attention, and that’s as it should be—unless, of course, one is more interested in a political agenda and willing to sacrifice judgment and good sense trying to substantiate that particular world view.
