Continued research with the tools of genetic epidemiology, population genetics, psychometrics, and cognitive neuroscience is likely to settle many of the contentious issues raised in Nisbett’s book, even without a centralized effort toward any such narrow goal. Given that much of the critical research so clearly lies ahead, Nisbett’s certainty regarding his own premature conclusions is quite remarkable. Some of this may be owed to the disturbing possibilities raised by the alternatives. Even the prospect that current group differences might be eliminated by a combination of biological enhancement and environmental improvement will fail to put all observers at ease, since the prospect of biologically based remedies is itself frightening to many. For what it is worth, I believe that the possibilities regarding both the state of nature and our powers of control should leave us reasonably optimistic about what the future might hold. But I confess to less than total confidence in even this qualified remark, and I envy Nisbett his certitude.
