2 genes do not make a voter

DURHAM, N.C. -- Voting behavior cannot be predicted by one or two genes as previous researchers have claimed, according to Evan Charney, a Duke University professor of public policy and political science.

In "Candidate Genes and Political Behavior," a paper published in the February 2012 American Political Science Review, Charney and co-author William English of Harvard University call into question the validity of all studies that claim that a common gene variant can predict complex behaviors such as voting.
