Parent Contributions to the Development of Political Attitudes in Adoptive and Biological Families

Where do our political attitudes originate? Although early research attributed the formation of such beliefs to parent and peer socialization, genetically sensitive designs later clarified the substantial role of genes in the development of sociopolitical attitudes. However, it has remained unclear whether parental influence on offspring attitudes persists beyond adolescence. In a unique sample of 394 adoptive and biological families with offspring more than 30 years old, biometric modeling revealed significant evidence for genetic and nongenetic transmission from both parents for the majority of seven political-attitude phenotypes. We found the largest genetic effects for religiousness and social liberalism, whereas the largest influence of parental environment was seen for political orientation and egalitarianism. Together, these findings indicate that genes, environment, and the gene–environment correlation all contribute significantly to sociopolitical attitudes held in adulthood, and the etiology and development of those attitudes may be more important than ever in today’s rapidly changing sociopolitical landscape.

Does Sexuality Matter? A Comparison of Heterosexuals’ and Sexual Minorities’ Sociopolitical Attitudes

Few researchers have examined the influence of sexuality on individuals’ sociopolitical attitudes. Using data from the 1991-2012 General Social Surveys (GSS) and 2008 American National Election Survey (ANES), I compare the social and political attitudes of heterosexuals and sexual minorities across a wide array of domains. Examining sixty measures of sociopolitical attitudes in the GSS, I find evidence that sexual minorities are significantly more liberal than their heterosexual counterparts across both sexual (e.g., sexual morality) and non-sexual (e.g., civil liberties, environmentalism) domains. In comparing the effect of sexuality on attitudes to the effects of gender, race, and education, I find that the influence of sexuality is comparable to these other well-documented sociodemographic predictors of attitudes. However, unlike these other sociodemographic characteristics, sexuality consistently predicts more liberal attitudes among sexual minorities compared to heterosexuals. Expanded analyses using 278 attitudinal items in the GSS and 64 in the ANES yield similar results. My findings provide evidence for the necessity to incorporate sexuality in future assessments of sociodemographic predictors of sociopolitical attitudes.

Early-Childhood Conduct Problems Predict Economic and Political Discontent in Adulthood: Evidence From Two Large, Longitudinal UK Cohorts

Longstanding interest has been directed toward the etiology of sociopolitical attitudes. Personality traits have been posited as antecedents; however, most work addressing such links has been limited to cross-sectional study designs. The current study used data from two large (both Ns > 8,700), longitudinal cohorts of individuals from the United Kingdom who were parent-assessed on a measure of temperament (assessing anxiety, conduct problems, and hyperactivity) at age 5 or 7 years and on a range of sociopolitical attitudes at age 30 or 33 years. In both cohorts, higher levels of childhood conduct problems predicted higher levels of economic and political discontent in adulthood. These associations were still evident when controlling for sex, childhood intelligence, and parental social class. In both cohorts, this pathway was partially mediated by educational attainment and achieved social class. These findings are consistent with the perspective that early-life temperament gives rise to adult political sentiment.

Genetic and environmental influences on sociopolitical attitudes

A new paradigm has emerged in which both genetic and environmental factors are cited as possible influences on sociopolitical attitudes. Despite the increasing acceptance of this paradigm, several aspects of the approach remain underdeveloped. Specifically, limitations arise from a reliance on a twins-only design, and all previous studies have used self-reports only. There are also questions about the extent to which existing findings generalize cross-culturally. To address those issues, this study examined individual differences in liberalism/conservatism in a German sample that included twins, their parents, and their spouses and incorporated both self- and peer reports. The self-report findings from this extended twin family design were largely consistent with previous research that used that rater perspective, but they provided higher estimates of heritability, shared parental environmental influences, assortative mating, and genotype-environment correlation than the results from peer reports. The implications of these findings for the measurement and understanding of sociopolitical attitudes are explored.

Does College Influence Sociopolitical Attitudes?

Past research shows a statistically significant relationship between college completion and sociopolitical attitudes. However, recent scholarship suggests the effects of college on social outcomes may be confounded with unobserved family background. In this study, we leverage the shared family and social background of siblings to better identify the effect of college on sociopolitical attitudes. We draw data from the Study of American Families and General Social Survey and use sibling fixed effects to assess the effect of college on political orientation, support for civil liberties, and beliefs about gender egalitarianism. We find that earning a four-year college degree has a significant impact on support for civil liberties and beliefs about gender egalitarianism, but the effect of college on political orientation is confounded by family background.
