Bourdieu's concept of habitus describes a set of tastes and dispositions operating according to a class homology -for example, a working-class preference for utility, or a bourgeois orientation toward luxury. In the United States, Holt found that high cultural capital consumers were characterized by their cosmopolitanism, idealism, connoisseurship, and affinity for the exotic and authentic. In this article, we use Holt's analysis as a comparative case, finding an altered high cultural capital habitus incorporating environmental awareness and sustainability principles, in a configuration that has been called ethical or ''conscious consumption.'' Using both quantitative survey data of self-described conscious consumers as well as four qualitative case studies, we argue that ethical consumers are overwhelmingly high cultural capital consumers, and that high cultural capital consumption strategies have shifted since Holt's study in the mid1990s. We show that on a number of dimensions -cosmopolitanism, idealism, and relation to manual labor -a new high cultural capital consumer repertoire privileges the local, material, and manual, while maintaining a strategy of distinction. While the critical literature on conscious consumers has suggested that such practices reflect neo-liberal tendencies that individualize environmental responsibility, our findings suggest that such practices are hardly individual. Rather, they are collective strategies of consumptionwhat we have termed an emerging high cultural capital ''eco-habitus.''

This study asks two related questions about the shifting landscape of marriage and reproduction in US society over the course of the last century with respect to a range of health and behavioral phenotypes and their associated genetic architecture: (i) Has assortment on measured genetic factors influencing reproductive and social fitness traits changed over the course of the 20th century? (ii) Has the genetic covariance between fitness (as measured by total fertility) and other traits changed over time? The answers to these questions inform our understanding of how the genetic landscape of American society has changed over the past century and have implications for population trends. We show that husbands and wives carry similar loadings for genetic factors related to education and height. However, the magnitude of this similarity is modest and has been fairly consistent over the course of the 20th century. This consistency is particularly notable in the case of education, for which phenotypic similarity among spouses has increased in recent years. Likewise, changing patterns of the number of children ever born by phenotype are not matched by shifts in genotype-fertility relationships over time. Taken together, these trends provide no evidence that social sorting is becoming increasingly genetic in nature or that dysgenic dynamics have accelerated.assortative mating | fertility | polygenic scores | cohort trends T he traditional view of evolutionary dynamics in humans was that the history of modern humans was too short for the species to have experienced substantive change in its genetic makeup (1, 2). However, findings from recent population genetics studies suggest the possibility that selective fertility, nonrandom mating, drift, and other violations of the Hardy-Weinberg equilibrium accelerated genetic divergence between modern human populations, particularly since humans began farming and civilization developed (3-6). Extending this logic, rapid economic development and the corresponding demographic transition over the past two centuries may have led to a further shift in the dynamics of reproduction and selection. The present paper uses genetic and phenotypic data from a nationally representative sample of US older adults to test whether the societal changes in the United States during the 20th century were reflected in (i) changes in patterns of genetic assortment in marriage, and (ii) changes in genetic influences on fertility.Understanding trends with respect to specific deviations from random mating and differential fertility is critical to both social and evolutionary scientists. For example, recent research in sociology has suggested that taking a prospective view on social stratification that incorporates differential fertility yields disparate results for estimands such as levels of intergenerational educational mobility (7). Likewise, genetic research on human populations often assumes that mating in a population is random with respect to genotypes (8, 9). Recent empirical evidence suggests otherw...

This study evaluates changes in genetic penetrance—defined as the association between an additive polygenic score and its associated phenotype—across birth cohorts. Situating our analysis within recent historical trends in the U.S., we show that, while height and BMI show increasing genotypic penetrance over the course of 20th Century, education and heart disease show declining genotypic effects. Meanwhile, we find genotypic penetrance to be historically stable with respect to depression. Our findings help inform our understanding of how the genetic and environmental landscape of American society has changed over the past century, and have implications for research which models gene-environment (GxE) interactions, as well as polygenic score calculations in consortia studies that include multiple birth cohorts.

Since the 1970s, social scientists have argued that general pro-environmental attitudes have diffused throughout American society, rendering socio-demographics largely irrelevant in predicting support for such issues. The public reaction to the issue of climate change, however, is an exception to this narrative. While media bias, ideological framing, and business influence are often invoked to explain public apathy, I argue that ignoring class and culture in determining why climate change is so divisive is a potentially significant oversight. Using the cultural theory of Bourdieu, I examine how the conception of and reaction to climate change varies with economic and cultural capital using data from 40 interviews of Boston-area respondents. The results suggest that climate change may indeed be a 'classed' issue-both in how the respondents conceive of it in the first place, and how they speak of social class in the context of it. The results suggest that social scientists should go beyond rational-choice and media framing explanations, to take two prolific examples, in exploring how disagreements on the importance of climate change persist in the US.

Previous scholarship pertaining to the social bases of proenvironmental behavior presents an equivocal picture of the influence of social class indicators. In further investigation of this possible association, the author examined municipal-level data in Massachusetts, compiled by various state agencies, exploring whether sociodemographics are associated with recycling rates, hybrid car ownership, and the presence of sustainability advocacy groups. Results indicate that the proportion of college-educated population was significantly associated with recycling and hybrid auto ownership, whereas results for the civic action group presence show population density and political voting were significant but not sociodemographics. The insignificance of economic metrics implies that policy makers and social scientists in this specific case should focus more on cultural factors than financial barriers in encouraging certain behaviors.

In this research note, we use data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to determine whether darker skin tone predicts hypertension among siblings using a family fixed-effects analytic strategy. We find that even after we account for common family background and home environment, body mass index, age, sex, and outdoor activity, darker skin color significantly predicts hypertension incidence among siblings. In a supplementary analysis using newly released genetic data from Add Health, we find no evidence that our results are biased by genetic pleiotropy, whereby differences in alleles among siblings relate to coloration and directly to cardiovascular health simultaneously. These results add to the extant evidence on color biases that are distinct from those based on race alone and that will likely only heighten in importance in an increasingly multiracial environment as categorization becomes more complex.

There is a growing interest in how social conditions moderate genetic influences on education [gene–environment interactions (GxE)]. Previous research has focused on the family, specifically parents’ social background, and has neglected the institutional environment. To assess the impact of macro-level influences, we compare genetic influences on educational achievement and their social stratification across Germany, Norway, Sweden, and the United States. We combine well-established GxE-conceptualizations with the comparative stratification literature and propose that educational systems and welfare-state regimes affect the realization of genetic potential. We analyse population-representative survey data on twins (Germany and the United States) and twin registers (Norway and Sweden), and estimate genetically sensitive variance decomposition models. Our comparative design yields three main findings. First, Germany stands out with comparatively weak genetic influences on educational achievement suggesting that early tracking limits the realization thereof. Second, in the United States genetic influences are comparatively strong and similar in size compared to the Nordic countries. Third, in Sweden genetic influences are stronger among disadvantaged families supporting the expectation that challenging and uncertain circumstances promote genetic expression. This ideosyncratic finding must be related to features of Swedish social institutions or welfare-state arrangements that are not found in otherwise similar countries.

The extent to which siblings resemble each other measures the total impact of family background in shaping life outcomes. We study sibling similarity in cognitive skills, school grades, and educational attainment in Finland, Germany, Norway, Sweden, the United Kingdom, and the United States. We also compare sibling similarity by parental education and occupation within these societies. The comparison of sibling correlations across and within societies allows us to characterize the omnibus impact of family background on education across social landscapes. We find similar levels of sibling similarity across social groups. Across countries, we find only small differences. In addition, rankings of countries in sibling resemblance differ across the three educational outcomes we study. We conclude that sibling similarity is largely similar across advanced, industrialized countries and across social groups within societies contrary to theories that suggest large cross-national differences and variation of educational mobility across social groups within societies.
