Keller explains the persistence of the nature/nurture debate by a chronic ambiguity in language derived from classical and behavioral genetics. She suggests that the more precise vocabulary of modern molecular genetics may be used to rephrase the underlying questions and hence provide a way out of this controversy. I show that her proposal fits into a long tradition in which other authors have wrestled with the same problem and come to similar conclusions. - Review of 'The mirage of a space (...) between nature and nurture' by Evelyn Fox Keller, Duke University Press, 2010, ISBN 9780822347316.

Genetic explanation of complex human behavior presents an excellent test case for pluralism. Although philosophers agree that successful scientific investigation of behavior is pluralistic, there remains disagreement regarding integration and elimination—is the plurality of approaches here to stay, or merely a waystation on the road to monism? In this paper we introduce an issue taken very seriously by scientists yet mostly ignored by philosophers—the missing heritability problem—and assess its implications for disagreement among pluralists. We argue that the missing heritability problem, (...) which isn’t going anywhere any time soon, implies that pluralism in behavior genetics is both practically ineliminative and theoretically non-integrative.

The phrase ‘social constructionism about race’ is so ambiguous that it is unable to convey anything very meaningful. I argue that the various versions of social constructionism about race are either false, overly broad, or better described as anti-realism about biological race. One of the central rhetorical purposes of social constructionism about race has been to serve as an alternative to biological racial realism. However, most versions of social constructionism about race are compatible with biological racial realism, and there are (...) some race scholars who endorse both positions. Going a step further, David Reich has recently defended both social constructionism about race and racial hereditarianism. While Reich’s defense of racial hereditarianism is unconvincing, I show that most versions of social constructionism about race are indeed compatible with racial hereditarianism. I argue that we ought to replace the social constructionist “consensus” about race with the view that there are no races, only racialized groups. (shrink)

Lucas Matthews and I substantially revised my SEP entry on Heritability. This version includes discussion of the missing heritability problem and other issues that arise from the use of Genome Wide Association Studies by Behavioral Geneticists.
