The Relationship between Education and Mental Health
Prior research has documented a strong and positive correlation between completed education and adults’ mental health. Researchers often describe this relationship using causal language: higher levels of education are thought to enhance people’s skills, afford important structural advantages, and empower better coping mechanisms, all of which lead to better mental health. An alternative explanation—the social selection hypothesis—suggests that sc…
Genetic influences on dietary variety - Results from a twin study
Genetic and Environmental Transmission of Political Orientations
This article reports results from the first twin study of adults in the United States that focuses exclusively and comprehensively on political traits. These data allow us to test whether a common set of genetic and environmental influences act upon a broad variety of values, personality traits, and political attitudes. In short, it allows us to empirically investigate whether there are a core set of predispositions that form the basis of our pol…
Maoa and Aggression
Political scientists tend to focus on environmental triggers as the primary precipitating cause for political violence. However, little has been done to explain why certain individuals faced with certain pressures resort to violence, while others confronting the same situation seek out diplomatic and peaceful resolutions to conflict. Here, using two independent samples, we explore the interaction between genetic disposition and violent early life…
Fear as a Disposition and an Emotional State
Fear is a pervasive aspect of political life and is often explored as a transient emotional state manipulated by events or exploited by elites for political purposes. The psychological and psychiatric literatures, however, have also established fear as a genetically informed trait, and people differ in their underlying fear dispositions. Here we propose these differences hold important implications for political preferences, particularly toward o…
Disentangling the Importance of Psychological Predispositions and Social Constructions in the Organization of American Political Ideology
Ideological preferences within the American electorate are contingent on both the environmental conditions that provide the content of the contemporary political debate and internal predispositions that motivate people to hold liberal or conservative policy preferences. In this article we apply Jost, Federico, and Napier's top‐down/bottom‐up theory of political attitude formation to a genetically informative population sample. In doing so, we fur…
It’s the end of ideology as we know it
Scholars have long focused on socio-psychological attachment, elite discourse, and rational action to explain the nature and structure of ideologies. Recently genetic and neurobiological influences have also emerged as predictors of ideological preferences. So far however, there has been little synthesis of these findings into the larger discourse on the structures and manifestations of ideology. The few studies which do include genetic sources o…
Biology, Ideology, and Epistemology
Evidence that political attitudes and behavior are in part biologically and even genetically instantiated is much discussed in political science of late. Yet the classic twin design, a primary source of evidence on this matter, has been criticized for being biased toward finding genetic influence. In this article, we employ a new data source to test empirically the alternative, exclusively environmental, explanations for ideological similarities …
Correlation not Causation
The assumption in the personality and politics literature is that a person's personality motivates them to develop certain political attitudes later in life. This assumption is founded on the simple correlation between the two constructs and the observation that personality traits are genetically influenced and develop in infancy, whereas political preferences develop later in life. Work in psychology, behavioral genetics, and recently political …
Population Composition, Public Policy, and the Genetics of Smoking
In this article, we explore the effect of public policy on the extent to which genes influence smoking desistance. Using a sample of adult twins (nmz = 363, ndz = 233) from a large population registry, we estimate Cox proportional hazards models that describe similarity in the timing of smoking desistance among adult twin pairs. We show that identical twin pairs are significantly more likely to quit smoking within a similar time frame compared wi…
Do We Choose Our Spouse Based on Our In‐Laws? Resolving the Effects of Family Background and Spousal Choice for Educational Attainment, Religious Practice, and Political Preference
Objectives Contemporary scholarly debate emphasizes the importance of spouse selection on population stratification, typically focusing on the traits of spouses themselves. In this study spouses and their parents were analyzed to resolve the effects of direct spousal assortment from family background assortment on three social traits that spouses correlate the highest: education, church attendance, and political affiliation. Methods The data set …
A Genome-Wide Analysis of Liberal and Conservative Political Attitudes
The assumption that the transmission of social behaviors and political preferences is purely cultural has been challenged repeatedly over the last 40 years by the combined evidence of large studies of adult twins and their relatives, adoption studies, and twins reared apart. Variance components and path modeling analyses using data from extended families quantified the overall genetic influence on political attitudes, but few studies have attempt…
The Politics of Mate Choice
Recent research has found a surprising degree of homogeneity in the personal political communication network of individuals but this work has focused largely on the tendency to sort into likeminded social, workplace, and residential political contexts. We extend this line of research into one of the most fundamental and consequential of political interactions—that between sexual mates. Using data on thousands of spouse pairs in the United States,…
Not by Twins Alone
Variance components estimates of political and social attitudes suggest a substantial level of genetic influence, but the results have been challenged because they rely on data from twins only. In this analysis, we include responses from parents and nontwin full siblings of twins, account for measurement error by using a panel design, and estimate genetic and environmental variance by maximum‐likelihood structural equation modeling. By doing so, …
Interaction Between the Serotonin Transporter Gene (5-HTTLPR), Stressful Life Events, and Risk of Depression
CONTEXT: Substantial resources are being devoted to identify candidate genes for complex mental and behavioral disorders through inclusion of environmental exposures following the report of an interaction between the serotonin transporter linked polymorphic region (5-HTTLPR) and stressful life events on an increased risk of major depression. OBJECTIVE: To conduct a meta-analysis of the interaction between the serotonin transporter gene and stress…
Genetic and Environmental Transmission of Political Attitudes Over a Life Time
Recently political scientists have looked anew at the source of political preferences and find support for the heuristic that political attitudes and behaviors are influenced by endogenous factors. The present research attempts to characterize how the transmission of political orientations develops over the life course. Using longitudinal data collected on twins throughout childhood and adolescence combined with cross-sectional data from adult tw…
Do Genes Contribute to the “Gender Gap
The nature and mechanisms underlying the differences in political preferences between men and women continues to be debated with little consideration for the biology of sex. Genetic influences on social and political attitudes have been reported for each sex independently, yet neither the magnitude nor sources of genetic influences have been explored for significant differences between males and females. In a large sample of adult twins, responde…
Is There a “Party” in Your Genes
Utilizing quantitative genetic models, the authors examine the sources of party identification and the intensity of that identification. The results indicate genes exert little, if any, influence on party identification, directly or indirectly through covariates. However, we find that genes appear to play a pivotal role in shaping the strength of an individual’s party identification. Together with recent examinations of political attitudes and vo…
A Twin Study of Sexual Behavior in Men
Depression scale scores in 8–17‐year‐olds
Background: The excess of unipolar depression in females emerges in adolescence. However, studies of age effects on depression scale scores have produced divergent estimates of changes from childhood to adolescence. Method: We explored possible reasons for this discrepancy in two large, longitudinal samples of twins and singletons aged 8–17. Results: There were no differences between twins and singletons in their scores on the Short Mood and Feel…
Testing hypotheses on specific environmental causal effects on behavior
There have been strong critiques of the notion that environmental influences can have an important effect on psychological functioning. The substance of these criticisms is considered in order to infer the methodological challenges that have to be met. Concepts of cause and of the testing of causal effects are discussed with a particular focus on the need to consider sample selection and the value (and limitations) of longitudinal data. The desig…
Understanding Biological and Social Influences on Religious Affiliation, Attitudes, and Behaviors
Although the transmission of religiousness has been assumed to be purely cultural, behavior genetic studies have demonstrated that genetic factors play a role in the individual differences in some religious traits. This article reviews the extant behavior genetic literature and presents new analyses from the “Virginia 30,000” on the causes of variation in religious affiliation, attitudes, and practices, and relates these to personality as constru…
Recovering components of variance from differential ratings of behavior and environment in pairs of relatives
Evidence from genetic studies underscores the importance of examining the within-family environment and its association with genetic differences among siblings in influencing children's development. Simulated and published data are analyzed to illustrate the contribution of genetic and environmental factors to differential ratings of behavioral and environmental differences within families. Comparison of the mean differential ratings within vario…
Genetic and Environmental Factors in Relative Body Weight and Human Adiposity
Genetic and environmental structure of the Tridimensional Personality Questionnaire
Previous phenotypic factor analyses suggest that C. R. Cloninger's Tridimensional Personality Questionnaire (TPQ; 1987c) assesses 4 rather than 3 temperament dimensions. The purpose of this study was to determine whether Cloninger's revised 4-factor model showed incremental validity over his original model and to investigate the convergent and discriminant validity of Cloninger's dimensions in comparison to the personality dimensions proposed by …

Social support, depressed mood, and adjustment to stress
A survey of 821 same-sex female twin pairs from a population-based registry assessed 8 dimensions of social support and social integration. Twin analyses documented significant common environmental influences on 5 of these 8 measures and significant genetic influences on 5 of the 8. A decomposition of the multiplicative association between support and a measure of stressful life experiences in predicting depressed mood--an association typically i…

The nature of extraversion
A biometrical-genetical analysis of twin data to elucidate the determinants of variation in extraversion and its components, sociability and impulsiveness, revealed that both genetical and environmental factors contributed to variation in extraversion, to the variation and covariation of its component scales, and to the interaction between subjects and scales. A large environmental correlation between the scales suggested that environmental facto…

Environmental and genetical causes of variation in ethological aspects of behavior in two‐year‐old boys
The interactive behavior of two‐year‐old male twins (17 MZ, 29 DZ pairs) with their parents was observed in the home and laboratory. Behavior counts, ratings, and experimental measures were subjected to a biometrical genetic analysis. A model which included only within‐and between‐families environmental effects fitted most variables best, except for Instrumental Independence (a rating) and Speech Rate (a count variable) which showed a significant…

The zygosity of twins
The agreement between zygosity diagnosis in twins by reference to the twins' own answers to written questions and diagnosis based on an objective assessment of zygosity by blood-typing is studied for 178 pairs of same sex twins. Seventy-two female and 106 male twin pairs answered two questions concerning their similarity in appearance and frequency of confusion in childhood, and were blood-grouped using up to 23 different antisera. Of those pairs…

Multiple Regression With Data Collected From Relatives
Multiple regression is a causal model of the relationship between sets of independent (X) and dependent (Y) variables. This model is extended to cover data collected from relatives, where the observations are not independent. If correct, the model permits appropriate statistical tests of regression coefficients in data collected from relatives. Across relative covariances, particularly across the independent and dependent variables may reject the…
