Genetic and environmental influences on sociopolitical attitudes

Evidence of correlations between human partners based on systematic reviews and meta-analyses of 22 traits and UK Biobank analysis of 133 traits

Positive correlations between mates can increase trait variation and prevalence, as well as bias estimates from genetically informed study designs. While past studies of similarity between human mating partners have largely found evidence of positive correlations, to our knowledge, no formal meta-analysis has examined human partner correlations across multiple categories of traits. Thus, we conducted systematic reviews and random-effects meta-analyses of human male-female partner correlations across 22 traits commonly studied by psychologists, economists, sociologists, anthropologists, epidemiologists and geneticists. Using ScienceDirect, PubMed and Google Scholar, we incorporated 480 partner correlations from 199 peer-reviewed studies of co-parents, engaged pairs, married pairs and/or cohabitating pairs that were published on or before 16 August 2022. We also calculated 133 trait correlations using up to 79,074 male-female couples in the UK Biobank (UKB). Estimates of the 22 mean meta-analysed correlations ranged from rmeta = 0.08 (adjusted 95% CI = 0.03, 0.13) for extraversion to rmeta = 0.58 (adjusted 95% CI = 0.50, 0.64) for political values, with funnel plots showing little evidence of publication bias across traits. The 133 UKB correlations ranged from rUKB = -0.18 (adjusted 95% CI = -0.20, -0.16) for chronotype (being a 'morning' or 'evening' person) to rUKB = 0.87 (adjusted 95% CI = 0.86, 0.87) for birth year. Across analyses, political and religious attitudes, educational attainment and some substance use traits showed the highest correlations, while psychological (that is, psychiatric/personality) and anthropometric traits generally yielded lower but positive correlations. We observed high levels of between-sample heterogeneity for most meta-analysed traits, probably because of both systematic differences between samples and true differences in partner correlations across populations.

Idealisation, genetic explanations and political behaviours: Notes on the anti-reductionist critique of genopolitics

The rapid development of genetic research, determined, among others, by the requirements of The Human Genome Project, and a gradual reorientation in the perception of the role of nature and culture in the process of shaping complex networks of human relations by some political scientists, result in the increasing application of genetic data and methods in research regarding political behaviours. One of the key philosophical objections against the studies of the genetic foundations of political behaviours is that of excessive reductionism. This is supposed to manifest itself in the inadequate selection of the level of analysis for the explained phenomenon, the incompleteness of explanations and their low utility. My findings show that this objection is not sufficiently supported by contemporary science. Both studies using classical behavioural genetic methodologies and studies using DNA-based methods show that genes most likely play a role in political behaviours. Emphasising the significance of genetic influences in the midst of multiple extra-genetic interactions generates highly idealised explanations. Using the conceptual apparatus of the deformational concept of culture, I have demonstrated that the omission of a number of important extra-genetic influences by researchers is a consequence of focusing on specific causal patterns. This omission, however, does not entail negating the influence of non-genetic factors and, importantly, it may not have to be permanent. Following this approach, if correct, the reductionism of research into the genetic foundations of political behaviours is a standard cognitive procedure applied in science.

A Clinician's Guide to Polycultural Psychiatry

Patients and families each present unique microcultures, mixing and blending numerous broadly conceptualized cultural identity groups. Within individuals and families, cultural identities are experienced and enacted as complex matrices of intersecting identities that, to varying degrees, complement, assimilate, accommodate, or clash. In these patterns, individuals' relationships to cultures are not necessarily categorically distinct ("multicultural"). Instead, they are often "polycultural," defined as partial and plural; rather than interpreting different cultural traditions as separate and independent, they are, within the lives of individuals and families, better understood as systems that interact with and influence one another.Cultural identity groups extend beyond those traditionally considered by transcultural psychiatry-that is, beyond ethnic, racial, and language groups. They encompass (in alphabetical order) educational, ethnic, extended family, gender-oriented, generational, geographic, language and dialect, organizational, physical or psychiatric disability, political, professional, racial, religious, sect, social class, and vocational identity groups, among others. Simplistic assumptions and generalities about identity groups risk cultural stereotyping that may negatively bias clinical assessments. Therefore, practitioners striving for cultural sensitivity need to adopt nuanced strategies for approaching broad polycultural identity questions in clinical practice. Accordingly, this article suggests frameworks and strategies for (1) assessing and confronting one's own cultural preconceptions and prejudices, and (2) developing etic (objective quantitative data) and emic (insiders' experiential worldviews) perspectives pertinent to clinical anthropathology. Both etic and emic perspectives are necessary for polyculturally nuanced, respectful, comprehensive inquiries pertinent to patients' and family's health beliefs, psychiatric difficulties, and health practices. Supplementary material from the DSM-5 section on cultural formulation is adapted and discussed, along with the implications of polycultural psychiatry for education and training in psychiatry.
