Item type:Publication, Universality of the Triangular Theory of Love: Adaptation and Psychometric Properties of the Triangular Love Scale in 25 Countries(Taylor & Francis, 2020-08-12)The Triangular Theory of Love (measured with Sternberg's Triangular Love Scale - STLS) is a prominent theoretical concept in empirical research on love. To expand the culturally homogeneous body of previous psychometric research regarding the STLS, we conducted a large-scale cross-cultural study with the use of this scale. In total, we examined more than 11,000 respondents, but as a result of applied exclusion criteria, the final analyses were based on a sample of 7332 participants from 25 countries (from all inhabited continents). We tested configural invariance, metric invariance, and scalar invariance, all of which confirmed the cultural universality of the theoretical construct of love analyzed in our study. We also observed that levels of love components differ depending on relationship duration, following the dynamics suggested in the Triangular Theory of Love. Supplementary files with all our data, including results on love intensity across different countries along with STLS versions adapted in a few dozen languages, will further enable more extensive research on the Triangular Theory of Love. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Conservatism negatively predicts creativity: A study across 28 countries(SAGE Publications Inc., 2024-06-01)Previous studies have found a negative relationship between creativity and conservatism. However, as these studies were mostly conducted on samples of homogeneous nationality, the generalizability of the effect across different cultures is unknown. We addressed this gap by conducting a study in 28 countries. Based on the notion that attitudes can be shaped by both environmental and ecological factors, we hypothesized that parasite stress can also affect creativity and thus, its potential effects should be controlled for. The results of multilevel analyses showed that, as expected, conservatism was a significant predictor of lower creativity, adjusting for economic status, age, sex, education level, subjective susceptibility to disease, and country-level parasite stress. In addition, most of the variability in creativity was due to individual rather than country-level variance. Our study provides evidence for a weak but significant negative link between conservatism and creativity at the individual level (β = −0.08, p <.001) and no such effect when country-level conservatism was considered. We present our hypotheses considering previous findings on the behavioral immune system in humans. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Modernization, Collectivism, and Gender Equality Predict Love Experiences in 45 Countries(Nature Research, 2023-12-01)Recent cross-cultural and neuro-hormonal investigations have suggested that love is a near universal phenomenon that has a biological background. Therefore, the remaining important question is not whether love exists worldwide but which cultural, social, or environmental factors influence experiences and expressions of love. In the present study, we explored whether countries’ modernization indexes are related to love experiences measured by three subscales (passion, intimacy, commitment) of the Triangular Love Scale. Analyzing data from 9474 individuals from 45 countries, we tested for relationships with country-level predictors, namely, modernization proxies (i.e., Human Development Index, World Modernization Index, Gender Inequality Index), collectivism, and average annual temperatures. We found that mean levels of love (especially intimacy) were higher in countries with higher modernization proxies, collectivism, and average annual temperatures. In conclusion, our results grant some support to the hypothesis that modernization processes might influence love experiences. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, I see sick people: Beliefs about sensory detection of infectious disease are largely consistent across cultures(Elsevier BV, 2025-08-01)Identifying cues to contagious disease is critical for effectively tracking and defending against interpersonal infection threats. People hold lay beliefs about the types of sensory information most relevant for identifying whether others are sick with transmissible illnesses. Are these beliefs universal, or do they vary along cultural and ecological dimensions? Participants in 58 countries (N = 19,217) judged how effective, and how likely they were to use, cues involving each of the five major sensory modalities in an imagined social interaction during a flu outbreak. Belief patterns were strongly consistent across countries (sight > audition > touch > smell > taste), suggesting a largely universal conceptualization of the role of sensory information for interpersonal respiratory disease detection. Results also support a safe senses hypothesis, with perceivers reporting that they would use senses that function at a distance—and thus reduce pathogen transmission risk—more than would be expected given participants’ beliefs as to the efficacy of these senses for disease detection. Where societal variation did emerge, it was captured by a cohesive set of socio-ecological factors, including human development, latitude, pathogen prevalence, and population density. Together, these findings reveal a shared lens through which contagious respiratory disease is assessed, one that prioritizes minimizing risk to perceivers, and may offer leverage for designing interventions to improve public health.4 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Examining the connection between position-based power and social status across 70 cultures(Wiley, 2025-04-01)Even in the most egalitarian societies, hierarchies of power and status shape social life. However, power and received status are not synonymous-individuals in positions of power may or may not be accorded the respect corresponding to their role. Using a cooperatively collected dataset from 18,096 participants across 70 cultures, we investigate, through a survey-based correlational design, when perceived position-based power (operationalized as influence and control) of various powerholders is associated with their elevated social status (operationalized as perceived respect and instrumental social value). We document that the positive link between power and status characterizes most cultural regions, except for WEIRD (Western, Educated, Industrialized, Rich, Democratic) and Post-Soviet regions. The strength of this association depends on individual and cultural factors. First, the perceived other-orientation of powerholders amplifies the positive link between perceived power and status. The perceived self-orientation of powerholders weakens this relationship. Second, among cultures characterized by low Self-Expression versus Harmony (e.g., South Korea, Taiwan), high Embeddedness (e.g., Senegal), and high Cultural Tightness (e.g., Malaysia), the association between power and status tends to be particularly strong. The results underline the importance of both individual perceptions and societal values in how position-based power relates to social status.2 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Beyond WEIRD societies: Global social identifications across 45 countries and their socio-cultural and economic predictors(Wiley, 2026-06-01)In an increasingly globalized world challenged by multiple social problems, global social identifications (GSIs, e.g., with all humanity) are concepts of growing interest. Although such identifications can be affected by the cultural contexts in which they are manifested, research on them remains largely confined to Western, Educated, Industrialized, Rich, Democratic (WEIRD) societies. Using data collected in 45 countries ( N = 9807, preregistered), we compared the strength of three types of GSIs between countries and cultural clusters, and explored the possible role of five cultural dimensions. The results revealed relatively small cross‐national differences in GSIs overall, but African and South‐East Asian cultural clusters reported significantly stronger identifications than those from other regions, with India, South Africa, and Ghana scoring the highest. Contrary to our hypotheses, GSIs were positively associated with in‐group collectivism, survival values, and traditional values, while institutional collectivism was unrelated. As expected, humane orientation was positively related to most GSIs. Additional exploratory analyses showed higher GSIs in countries with a lower quality of life (broadly understood). GSIs were also more pronounced in less globalized, younger societies, with a higher proportion of men, fewer immigrants, and stronger diversity. Our study highlights the need to broaden research on GSIs beyond WEIRD contexts.
