Politics, Policy, and Ethics contains informative chapters on the history of psychiatric "brain intervention" from lobotomies to deep brain stimulation; how advances in neuroscience have impacted the definition of death; and the commercial and military applications of new neuroscience technologies. The bulk of the book, however, is devoted to making the argument that advances in neuroscience have significantly advanced our understanding of social, political, and moral behavior.

Man Is by Nature a Political Animal: Evolution, Biology, and Politics. Edited by Peter K. Hatemi and Rose McDermott. Chicago: The University of Chicago Press, 2011. 352p. $80.00 cloth, $27.50 paper.Peter K. Hatemi and Rose McDermott's Man Is by Nature a Political Animal brings together some of the most important social scientists working at the intersection of political science, psychology, biology, and cognitive neuroscience. Given recent advances in cognitive neuroscience and given the proliferation of work in political science that draws on these advances, we have decided to invite a range of political scientists to comment on the promise and the limits of this line of inquiry. What can scientific developments in psychology, biology, and neuroscience tell us about "human nature"? Can these discourses reckon with the variation in time and space that has traditionally been at the heart of political science, perhaps even going back to the classic text from which Hatemi and McDermott derive their title, Aristotle's Politics?—Jeffrey C.

I would like to thank Alford, Funk, and Hibbing, and Hannagan and Hatemi, for agreeing to write critical responses to my article, and I am grateful for the opportunity afforded me to respond.

AbstractThere is a trend among behavioral scientists to view ever more complex attitudes or systems of belief as in some sense genetically determined (or "heritable"). Consistent with this trend is the recent article of Alford, Funk, and Hibbing titled "Are Political Orientations Genetically Transmitted?" in which the authors claim to have demonstrated that when it comes to the transmission of political ideologies, genes count for more than environment. Their article has received an enormous amount of attention among political scientists and in the popular press. I critically evaluate the research technique on the basis of which the authors' support their claims and argue that it suffers from significant methodological flaws. Such flaws notwithstanding, I demonstrate that the authors' data do not clearly support their conclusions. I then question the cogency, from an historical and theoretical perspective, of proposing the existence of "liberal" and "conservative" "phenotypes" and "genotypes." My argument has implications beyond the findings of Alford, Funk, and Hibbing, and applies to all studies that claim to have demonstrated the heritability of complex and politically relevant attitudes.
