There has been a recent increase in interest in the psychological differences and antecedents related to political orientation. Personality, disgust sensitivity, attachment, and closeness to parents have all been found or have been theorized to be predictive of political orientation. These variables and the additional roles played by normative identity style and parental identification were examined. The results showed that normative identity style is associated with political orientation and that the role played by parental identification depends on the perceived parental political ranking, the gender of the parent, and the measure used to examine political orientation. No support was found for Lakoff's (2002) model of parenting and political orientation.Recently there has been a surge in interest in the psychological foundations of political orientation (Jost 2006). While a significant portion of the variance in political orientation is explained by individual genetic differences (Alford et al. 2005), heritability estimates of political attitudes show that both shared and nonshared environmental effects explain sizable amounts of variance for attitudes on the majority of political issues studied. Also, genes do not directly influence political orientation (i.e., there are not genes for being a Democrat or Republican) and therefore the variance explained by heritability estimates on political attitudes is due to any number of mediating psychological variables.
