A Genetic Basis of Economic Egalitarianism
- 445 Downloads
Studies of political attitudes and ideologies have sought to explain their origin. They have been assumed to be a result of political values ingrained during the process of socialization until early adulthood, as well as personal political experience, party affiliation, social strata, etc. As a consequence of these environment-dominated explanations, most biology-based accounts of political preference have never been considered. However, in the light of evidence accumulated in recent years, the view that political attitudes are detached from any physical properties became unsustainable. In this paper, we investigate the origins of social justice attitudes, with special focus on economic egalitarianism and its potential genetic basis. We use Minnesota Twin Study data from 2008, collected from samples of monozygotic and dizygotic twin pairs (n = 573) in order to estimate the additive genetic, shared environmental, and unique environmental components of social justice attitudes. Our results show that the large portion of the variance in a four-item economic egalitarianism scale can be attributed to genetic factor. At the same time, shared environment, as a socializing factor, has no significant effect. The effect of environment seems to be fully reserved for unique personal experience. Our findings further problematize a long-standing view that social justice attitudes are dominantly determined by socialization.
