In a review of Richard Lynn's book on the Pioneer Fund, psychologist Ulrich Neisser, a critic of race-based research, writes: "All things considered, I doubt that the Pioneer Fund's political activities have made much difference one way or the other. The world would have been much the same without them. On the other hand, Lynn reminds us that Pioneer has sometimes sponsored useful research – research that otherwise might not have been done at all. By that reckoning, I would give it a weak plus."
