Who is more prone to depression at higher latitudes? Islanders or mainlanders?

Across 195 countries, rates of depressive disorders in women and men are higher among islanders (relative to mainlanders) at more northern locations in the Northern Hemisphere and at more southern locations in the Southern Hemisphere. Our explanatory analyses show that the three-way interaction of greater daylength variability, being more of an islander, and adopting a more individualistic culture accounts for higher rates of depression in both genders. Differences in longitude, photoperiod, phase shift, disaster risk, economic poverty, income inequality, and urbanization level do not appear to account for the oppositely sloping north-south gradients of depression above and below the equator

Cognitive Inflexibility Predicts Extremist Attitudes.

Research into the roots of ideological extremism has traditionally focused on the social, economic, and demographic factors that make people vulnerable to adopting hostile attitudes toward outgroups. However, there is insufficient empirical work on individual differences in implicit cognition and information processing styles that amplify an individual's susceptibility to endorsing violence to protect an ideological cause or group. Here we present original evidence that objectively assessed cognitive inflexibility predicts extremist attitudes, including a willingness to harm others, and sacrifice one's life for the group. Across two samples (N = 1,047) from the United Kingdom and United States, structural equation models demonstrated that cognitive inflexibility predicted endorsement of violence to protect the national ingroup, which in turn predicted a willingness to die for the group. These statistical models accounted for an average of 31.4% of the variance in willingness to die for the group, after accounting for demographic variables. Furthermore, cognitive inflexibility was related to greater confidence in the decision to sacrifice one's life in an ingroup trolley problem scenario. Analysis of participants' performance on the cognitive tasks revealed that cognitive rigidity - distinctly from other aspects of cognition - was specifically implicated as a cognitive antecedent of extremist attitudes. Implications for the study of radicalization and identity fusion through a neurocognitive lens are discussed

Religious people only live longer in religious cultural contexts: A gravestone analysis.

Religious people live longer than non-religious people according to a staple of social science research. Yet, are those longevity benefits an inherent feature of religiosity? To find out, we coded gravestone inscriptions and imagery in order to assess the religiosity and longevity of 6,400 deceased people from religious and non-religious U.S. counties. We show that in religious cultural contexts, religious people lived 2.2 years longer than did non-religious people. In non-religious cultural contexts, however, religiosity conferred no such longevity benefits. Evidently, a longer life is not an inherent feature of religiosity. Instead, religious people only live longer in religious cultural contexts where religiosity is valued. Our study answers a fundamental question on the nature of religiosity and showcases the scientific potential of gravestone analyses

Musical preferences predict personality: evidence from active listening and Facebook likes

Research over the past decade has shown that various personality traits are communicated through musical preferences. One limitation of that research is external validity, as most studies have assessed individual differences in musical preferences using self-reports of music-genre preferences. Are personality traits communicated through behavioral manifestations of musical preferences? We addressed this question in two large-scale online studies with demographically diverse populations. Study 1 (N = 22,252) shows that reactions to unfamiliar musical excerpts predicted individual differences in personality—most notably, openness and extraversion—above and beyond demographic characteristics. Moreover, these personality traits were differentially associated with particular music-preference dimensions. The results from Study 2 (N = 21,929) replicated and extended these findings by showing that an active measure of naturally occurring behavior, Facebook Likes for musical artists, also predicted individual differences in personality. In general, our findings establish the robustness and external validity of the links between musical preferences and personality

Fear, populism, and the geopolitical landscape: the “sleeper effect” of neurotic personality traits on regional voting behavior in the 2016 Brexit and Trump elections

Two recent electoral results - Donald Trump’s election as US president and the UK’s Brexit vote - have re-ignited debate on the psychological factors underlying voting behavior. Both campaigns promoted themes of fear, lost pride, and loss aversion, which are relevant to the personality dimension of Neuroticism, a construct previously not associated with voting behavior. To that end, we investigate whether regional prevalence of neurotic personality traits (Neuroticism, Anxiety, Depression) predicted voting behavior in the US (N = 3,167,041) and the UK (N = 417,217), comparing these effects with previous models, which have emphasized the roles of Openness and Conscientiousness. Neurotic traits positively predicted share of Brexit and Trump votes and Trump gains from Romney. Many of these effects persisted in additional robustness tests controlling for regional industrial heritage, political attitude, and socio-economic features, particularly in the US. The “sleeper effect” of neurotic traits may profoundly impact the geopolitical landscape

Does Shyness Vary According to Attained Social Roles? Trends Across Age Groups in a Large British Sample

OBJECTIVE: The current study investigated (a) how a composite measure of shyness comprising introversion and neuroticism relates to other well-known constructs involving social fears, and (b) whether mean levels of shyness vary for men and women depending on the adoption of various social roles. METHOD: Study 1 used a sample of 211 UK participants aged 17–70 (64% female; Mage = 47.90). Study 2 used data from a large cross-sectional data set with UK participants aged 17–70 (Ntarget = 552,663; 64% female; Mage = 34.19 years). RESULTS: Study 1 showed that shyness measured as a composite of introversion and neuroticism was highly correlated with other constructs involving social fears. Study 2 indicated that, controlling for various sociodemographic variables, females appeared to have higher levels, whereas males appeared to have lower levels of shyness. Males and females who were in employment had the lowest shyness levels, whereas those working in unskilled jobs had the highest levels and people working in sales the lowest levels of shyness. Participants in relationships had lower levels of shyness than those not in relationships, but parenthood was not associated with shyness. CONCLUSIONS: Mean levels of shyness are likely to vary according to adopted social roles, gender, and age.Preparation of this manuscript was supported by Grant 2011-0307 from the Swedish Research Council for Health, Working Life and Welfare to Nejra Van Zalk

Entrepreneurship Culture, Knowledge Spillovers, and the Growth of Regions

An extensive literature has emerged in regional studies linking organization-based measures of entrepreneurship (e.g., self-employment, new start-ups) to regional economic performance. A limitation of the extant literature is that the measurement of entrepreneurship is not able to incorporate broader conceptual views, such as behaviour, of what actually constitutes entrepreneurship. This paper fills this gap by linking the underlying and also more fundamental and encompassing entrepreneurship culture of regions to regional economic performance. The empirical evidence suggests that those regions exhibiting higher levels of entrepreneurship culture tend to have higher employment growth. Robustness checks using causal methods confirm this finding

Happiness around the world: A combined etic-emic approach across 63 countries.

What does it mean to be happy? The vast majority of cross-cultural studies on happiness have employed a Western-origin, or "WEIRD" measure of happiness that conceptualizes it as a self-centered (or "independent"), high-arousal emotion. However, research from Eastern cultures, particularly Japan, conceptualizes happiness as including an interpersonal aspect emphasizing harmony and connectedness to others. Following a combined emic-etic approach (Cheung, van de Vijver & Leong, 2011), we assessed the cross-cultural applicability of a measure of independent happiness developed in the US (Subjective Happiness Scale; Lyubomirsky & Lepper, 1999) and a measure of interdependent happiness developed in Japan (Interdependent Happiness Scale; Hitokoto & Uchida, 2015), with data from 63 countries representing 7 sociocultural regions. Results indicate that the schema of independent happiness was more coherent in more WEIRD countries. In contrast, the coherence of interdependent happiness was unrelated to a country's "WEIRD-ness." Reliabilities of both happiness measures were lowest in African and Middle Eastern countries, suggesting these two conceptualizations of happiness may not be globally comprehensive. Overall, while the two measures had many similar correlates and properties, the self-focused concept of independent happiness is "WEIRD-er" than interdependent happiness, suggesting cross-cultural researchers should attend to both conceptualizations

The Musicality of Non-Musicians: An Index for Assessing Musical Sophistication in the General Population

Musical skills and expertise vary greatly in Western societies. Individuals can differ in their repertoire of musical behaviours as well as in the level of skill they display for any single musical behaviour. The types of musical behaviours we refer to here are broad, ranging from performance on an instrument and listening expertise, to the ability to employ music in functional settings or to communicate about music. In this paper, we first describe the concept of ‘musical sophistication’ which can be used to describe the multi-faceted nature of musical expertise. Next, we develop a novel measurement instrument, the Goldsmiths Musical Sophistication Index (Gold-MSI) to assess self-reported musical skills and behaviours on multiple dimensions in the general population using a large Internet sample (n = 147,636). Thirdly, we report results from several lab studies, demonstrating that the Gold-MSI possesses good psychometric properties, and that self-reported musical sophistication is associated with performance on two listening tasks. Finally, we identify occupation, occupational status, age, gender, and wealth as the main socio-demographic factors associated with musical sophistication. Results are discussed in terms of theoretical accounts of implicit and statistical music learning and with regard to social conditions of sophisticated musical engagement
