It Is Not Only the Environment That Matters: A Short Introduction to Research on the Heritability of Political Attitudes

In the article, we review key methodological issues and study results on the heritability of political attitudes. These studies show to what degree the variance of observed attitudes can be explained by genetic variance. We have analysed studies differing in terms of applied methods, techniques and research tools, as well as sample populations of different age and sex structures. Regardless of these differences, the studies show that political attitudes are most likely influenced to some extent by genetic factors. This research suggests that the influence of genes on attitudes is subject to change over the life cycle. It also provides knowledge regarding the mechanisms that may link genes and attitudes. The studies conducted to date offer the opportunity to broaden the culturalism-based explanations of political attitudes with biological aspects; however, they also point to several issues that will require additional attention from the researchers.

Automated summary

This article reviews research on the heritability of political attitudes, examining different methods and sample populations. The studies suggest that genetic factors play a role in shaping political attitudes and highlight the need for further research on the mechanisms behind this influence.
