Genetics and Heritability Research on Political Decision Making (2020)
in: Oxford Research Encyclopedia of Politics
In 2005, political scientists claimed that parent-child similarities, in addition to parenting, socialization, or shared social factors by the family, are also driven by genetic similarity. This claim upended a century of orthodoxy in political science. Many social scientists are uncomfortable with this concept, and this discomfort often stems from a multitude of misunderstandings. Claims about the genetics and heritability of political phenomena predate 2005 and wave of studies over the decade that followed swept through political science and then died down as quickly as they came. The behavior genetic research agenda faces several challenges within political science, including (a) resistance to these ideas within all of the social sciences, (b) difficulties faced by scholars in the production of meaningful theoretical and empirical contributions, and (c) developments in the field of genetics and their (negative) impact on the related scholarship within the study of politics.
