Two-Dimensional Machiavellianism: Conceptualisation, Measurement, and Well-Being

Individuals learn to influence and manipulate others to function as part of society. Machiavellianism captures one’s willingness to orchestrate the behaviour of others against their interests, rights, and well-being. Research focuses primarily on a single Machiavellianism dimension. This thesis, however, contends that Machiavellianism comprises two correlated dimensions: a views dimension that captures one's cynical and distrusting view of humanity and the world, and a tactics dimension that captures one’s willingness to endorse exploitative and amoral behaviours when deemed advantageous. This thesis aimed to develop a stronger understanding of each dimension, and this required developing stronger psychometric instruments. The secondary aim was to test the presupposition of no psychopathological cost to Machiavellianism. After an initial foray into Machiavelli and Machiavellianism in the first two chapters, Chapter 3 identifies a robust Machiavellianism factor-structure and how each dimension relates to psychopathological domains in 1478 US and 218 Australian participants. Confirmatory factor analysis demonstrated that Machiavellianism comprises two robust dimensions which could be reliably captured through a 10-item subset of the Mach-IV scale, named Two-Dimensional Mach-IV (TDM-IV). Further, Machiavellian views associated with all major psychological domains, while Machiavellian tactics related only to the externalising and thought dysfunction domains. Machiavellianism is two-dimensional, with each dimension having distinctive psychopathological implications. The study in Chapter 4 investigates whether these two dimensions are universal, or merely measurement artefacts within Study 1. If universal, this research further aimed to develop a nomological network to better understand the nature of each dimension. International collaborators shared 15 datasets, which comprisedover 17,000 participants. The two-factor structure was reproducible and structurally equivalent across cultures, languages, types of respondent, response category length, age, and gender. Further, each dimension was situated within a different constellation of broad personality traits, developmental pathways, emotionality, and behaviour. Therefore, the two dimensions appear to be core aspects of Machiavellianism and need to be independently captured in future research. The TDM-IV derives from the Mach-IV, inheriting many of its psychometric concerns that reduce the accuracy of its inferences, such as confusing item wording and not accounting for acquiesces appropriately. To overcome these weaknesses, Chapter 5 presents the development and validation of the Two-Dimensional Machiavellianism Scale (TDMS). The TDMS had excellent psychometric properties in six independent samples involving over 3800 participants, based on confirmatory factor analysis, longitudinal structural equation modelling, and item response theory. The scale provided invariant measurement across all samples and a test-retest sample, was internally consistent, and provided most information in the low to high average range. This study demonstrates confirmatory and discriminatory validity with existing measures of Machiavellianism, broader personality taxonomies, socio-political attitudes, psychopathy, narcissism, and morality vignettes. Finally, Chapter 6 explicates this two-dimensional Machiavellianism construct and discusses key areas for future investigation, including latent profiles, longitudinal modelling of each dimension’s development, and cross-cultural equivalence. Together, this research demonstrates that: a) Machiavellianism comprises two distinct dimensions, b) the TDMS, as a psychometrically robust measure of Machiavellianism, should replace current measures of Machiavellianism, and c) the presupposition of psychopathological immunity among Machiavellians is false

Item response theory approach to ethnocentrism

IntroductionAlthough ethnocentrism is one of the fundamental concepts in the social sciences, its study has been impeded by a diversity of conceptualizations and measures. In recent years, a growing number of political scientists and psychologists have undertaken in-depth research into ethnocentrism. In addition, researchers have recently proposed a comprehensive reconceptualization of ethnocentrism and developed a new Ethnocentrism scale. There is strong evidence for this scale's reliability and validity in indexing ethnocentrism, but like most measures in psychology and political science, this scale is based on classical test theory. Item response theory (IRT) is a powerful psychometric technique that can provide a much more sophisticated test of test performance and is currently under-utilized in research.MethodsWe performed IRT to assess the psychometric properties of the Ethnocentrism scale on a sample of 4,187 participants.ResultsThe scale's items had strong psychometric properties to capture the ethnocentrism latent construct, particularly in the below average to above average range. Men required marginally lower levels of ethnocentrism to endorse less socially acceptable items than women (items relating to superiority, purity, or exploitativeness). When compared to liberals, conservatives responded more readily to nearly all ethnocentrism items. Given this variation, the IRT approach highlighted that future measurements must adjust for differential item functioning, albeit more for political orientation than gender identity.DiscussionThe findings detail how IRT can enhance measurement in political science and demonstrate the implications for how gender and political ideology may affect the differential performance of items

Solastalgia mediates between bushfire impact and mental health outcomes: A study of Australia\u27s 2019–2020 bushfire season

In 2019–2020, Australia experienced an unprecedented bushfire season that caused widespread environmental destruction across the continent, and especially to its south-east corner. Over two studies, we examine mental health outcomes of individuals impacted by bushfire, drawing on the concept of solastalgia – the sense of distress arising from unwanted environmental change – as a potential explanation for the mental health consequences of bushfire. In Study 1, we surveyed 2084 residents from the Australian Capital Territory and surrounding regions directly after the bushfire season. Participants were asked about exposure to the 2019–2020 bushfires, and to a previous regional fire of significance, experience of solastalgia, and five mental health indicators. In Study 2, we broaden our focus to all of Australia, and administer our measures with a nationally representative sample six months after the conclusion of the bushfire season (N = 1477). In both studies, we find the severity of reported bushfire impact is significantly associated with mental health, such that greater impact predicts poorer outcomes. Moreover, we find the experience of solastalgia mediates the relationship between bushfire impact and mental health and wellbeing. Experiencing solastalgia is a partial, but important, mechanism for understanding the impact of bushfire exposure on mental health and wellbeing. Importantly, people not directly impacted by a bushfire event also experience solastalgia and subsequent poorer mental health outcomes following bushfires. We suggest that future measurements of the impact of abrupt environmental change events, including bushfires, consider the role of solastalgia and localised environmental contexts in shaping the mental health impacts to the population

Contrasting Computational Models of Mate Preference Integration Across 45 Countries

Humans express a wide array of ideal mate preferences. Around the world, people desire romantic partners who are intelligent, healthy, kind, physically attractive, wealthy, and more. In order for these ideal preferences to guide the choice of actual romantic partners, human mating psychology must possess a means to integrate information across these many preference dimensions into summaries of the overall mate value of their potential mates. Here we explore the computational design of this mate preference integration process using a large sample of n = 14,487 people from 45 countries around the world. We combine this large cross-cultural sample with agent-based models to compare eight hypothesized models of human mating markets. Across cultures, people higher in mate value appear to experience greater power of choice on the mating market in that they set higher ideal standards, better fulfill their preferences in choice, and pair with higher mate value partners. Furthermore, we find that this cross-culturally universal pattern of mate choice is most consistent with a Euclidean model of mate preference integration.The work of Truong Ti Khanh Ha was supported by grants 501.01–2016.02 from the Vietnam National Foundation for Science and Technology Development (NAFOSTED).

Love and affectionate touch toward romantic partners all over the world

Touch is the primary way people communicate intimacy in romantic relationships, and affectionate touch behaviors such as stroking, hugging and kissing are universally observed in partnerships all over the world. Here, we explored the association of love and affectionate touch behaviors in romantic partnerships in two studies comprising 7880 participants. In the first study, we used a cross-cultural survey conducted in 37 countries to test whether love was universally associated with affectionate touch behaviors. In the second study, using a more fine-tuned touch behavior scale, we tested whether the frequency of affectionate touch behaviors was related to love in romantic partnerships. As hypothesized, love was significantly and positively associated with affectionate touch behaviors in both studies and this result was replicated regardless of the inclusion of potentially relevant factors as controls. Altogether, our data strongly suggest that affectionate touch is a relatively stable characteristic of human romantic relationships that is robustly and reliably related to the degree of reported love between partners.info:eu-repo/semantics/publishedVersio

Reasons for facebook usage: Data from 46 countries

Seventy-nine percent of internet users use Facebook, and on average they access Facebook eight times a day (Greenwood et al., 2016). To put these numbers into perspective, according to Clement (2019), around 30% of the world\u2019s population uses this Online Social Network (OSN) site. Despite the constantly growing body of academic research on Facebook (Chou et al., 2009; Back et al., 2010; Kaplan and Haenlein, 2010; McAndrew and Jeong, 2012; Wilson et al., 2012; Krasnova et al., 2017), there remains limited research regarding the motivation behind Facebook use across different cultures. Our main goal was to collect data from a large cross-cultural sample of Facebook users to examine the roles of sex, age, and, most importantly, cultural differences underlying Facebook use

Affective interpersonal touch in close relationships: a cross-cultural perspective

Interpersonal touch behavior differs across cultures, yet no study to date has systematically tested for cultural variation in affective touch, nor examined the factors that might account for this variability. Here, over 14,000 individuals from 45 countries were asked whether they embraced, stroked, kissed, or hugged their partner, friends, and youngest child during the week preceding the study. We then examined a range of hypothesized individual-level factors (sex, age, parasitic history, conservatism, religiosity, and preferred interpersonal distance) and cultural-level factors (regional temperature, parasite stress, regional conservatism, collectivism, and religiosity) in predicting these affective-touching behaviors. Our results indicate that affective touch was most prevalent in relationships with partners and children, and its diversity was relatively higher in warmer, less conservative, and religious countries, and among younger, female, and liberal people. This research allows for a broad and integrated view of the bases of cross-cultural variability in affective touch

Sex differences in mate preferences across 45 countries: A large-scale replication

Considerable research has examined human mate preferences across cultures, finding universal sex differences in preferences for attractiveness and resources as well as sources of systematic cultural variation. Two competing perspectives—an evolutionary psychological perspective and a biosocial role perspective—offer alternative explanations for these findings. However, the original data on which each perspective relies are decades old, and the literature is fraught with conflicting methods, analyses, results, and conclusions. Using a new 45-country sample (N = 14,399), we attempted to replicate classic studies and test both the evolutionary and biosocial role perspectives. Support for universal sex differences in preferences remains robust: Men, more than women, prefer attractive, young mates, and women, more than men, prefer older mates with financial prospects. Cross-culturally, both sexes have mates closer to their own ages as gender equality increases. Beyond age of partner, neither pathogen prevalence nor gender equality robustly predicted sex differences or preferences across countries
