Genes and Ideologies

Abstract

Abstract There 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.
