Greenleaf’s foundational work on servant leadership has evolved considerably over the past 50 years. Servant leadership has been found to have positive outcomes on group and organisational effectiveness. While servant leadership characteristics and outcomes have been measured, is a need to be better understand how servant leaders navigate when they disagree. Using a social and cultural analysis, the conflict between Paul and Barnabas is explored. Social and cultural analysis allows interpreters to understand what the characters in the narrative ‘see and (...) hear.’ The analysis of Acts 15:36–41 yielded three emerging themes related to how these servant leaders navigated conflict: (1) the tension created by conflict, (2) leader maturity and conflict and (3) the effectiveness of servant leadership amid differences. It was found that servant leaders are not immune from conflict, and when two servant leaders disagree it creates tension between the various servant leader behaviours. Furthermore, a leader’s experience and maturity influence their responses to conflict. Lastly, it was found that servant leaders do not allow conflict to derail their mission.Contribution: This article contributes to the body of knowledge on servant leadership by exploring how servant leaders navigate conflict from a biblical perspective. By exploring servant leadership behaviours from a biblical perspective, this article contributes to the interdisciplinary focus of HTS Teologiese Studies/Theological Studies, engaging social scientific constructs through a New Testament paradigm.

The study of servant leadership has been extensively defined with a list of applicable attributes; however, has limited guidance on implementation of a servant leadership culture within an existing leadership culture. The research gap was addressed through socio-rhetorical analysis using social and cultural texture of the Matthew 20:20-28 pericope. The exegetical analysis revealed five emerging themes applicable to Jesus’ methods of servant leadership implementation. These transitioning themes included: organizational order of change, everyone matters, new identity and values, implementation without compromise, (...) and speak more about the new than the old.

Background This paper describes the design, implementation, and process outcomes from three public deliberations held in three tribal communities. Although increasingly used around the globe to address collective challenges, our study is among the first to adapt public deliberation for use with exclusively Indigenous populations. In question was how to design deliberations for tribal communities and whether this adapted model would achieve key deliberative goals and be well received.Methods We adapted democratic deliberation, an approach to stakeholder engagement, for use with (...) three tribal communities to respect tribal values and customs. Public deliberation convenes people from diverse backgrounds in reasoned reflection and dialogue in search of collective solutions. The deliberation planning process and design were informed by frameworks of enclave deliberation and community-based participatory research, which share key egalitarian values. The deliberations were collaboratively designed with tribal leadership and extensive partner input and involvement in the deliberations. Each deliberation posed different, locally relevant questions about genomic research, but used the same deliberation structure and measures to gauge the quality and experience of deliberation.Results A total of 52 individuals participated in the deliberations across all three sites. Deliberants were balanced in gender, spanned decades in age, and were diverse in educational attainment and exposure to health research. Overall, the deliberations were positively evaluated. Participant perceptions and external observer datasets depict three deliberations that offered intensive conversation experiences in which participants learned from one another, reported feeling respected and connected to one another, and endorsed this intensive form of engagement.Conclusion The adapted deliberations achieved key deliberative goals and were generally well received. Limitations of the study are described. (shrink)

There has been increased interest in the potential of maternal immunisation to protect maternal, fetal, and infant health. Maternal tetanus vaccination is part of routine antenatal care and immunisation campaigns in many countries, and it has played an important part in the reduction of maternal and neonatal tetanus. Additional vaccines that have been recommended for routine maternal immunisation include those for influenza and pertussis, and other vaccines are being developed. Maternal immunisation is controversial since regulators, professionals, and the public are (...) often reluctant to accept pharmaceutical interventions during pregnancy. So far, little attention has been given to the ethics of vaccination during pregnancy. In this Personal View we argue that maternal immunisation should be offered in response to concrete, severe risks of disease for mother and child, and we explain how this requirement of serious risk can be used to guide ethical decision-making about maternal immunisation.

Dynamic intra-individual variability (IIV) in cardiac vagal control across multiple situations is believed to contribute to adaptive cognition under stress; however, a dearth of research has empirically tested this notion. To this end, we examined 25 U.S. Army Soldiers (all male, Mean Age= 30.73, SD = 7.71) whose high-frequency heart rate variability (HF-HRV) was measured during a resting baseline and during three conditions of a shooting task (training, low stress, high stress). Response inhibition was measured as the correct rejection of (...) friendly targets during the low and high stress conditions. We tested the association between the standard deviation of HF-HRV across all four task conditions (IIV in vagal control) and changes in response inhibition between low and high stress. Greater differences in vagal control between conditions (larger IIV) were associated with higher tonic vagal control during rest, and stronger stress-related decreases in response inhibition. These results suggest that flexibility in vagal control is supported by tonic vagal control, but this flexibility also uniquely relates to adaptive cognition under stress. Findings are consistent with neurobehavioral and dynamical systems theories of vagal function. (shrink)

Common symptoms of multiple sclerosis include motor impairments of the lower extremities, particularly gait disturbances. Loss of balance and muscle weakness, representing some peripheral effects, have been shown to influence these symptoms, however, the individual role of cortical and subcortical structures in the central nervous system is still to be understood. Assessing [18F]fluorodeoxyglucose uptake in the CNS can assess brain activity and is directly associated with regional neuronal activity. One potential modality to increase cortical excitability and improve motor function in (...) patients with MS is transcranial direct current stimulation. However, tDCS group outcomes may not mirror individual subject responses, which impedes our knowledge of the pathophysiology and management of diseases like MS. Three PwMS randomly received both 3 mA tDCS and SHAM targeting the motor cortex that controls the more-affected leg for 20 min on separate days before walking on a treadmill. The radiotracer, FDG, was injected at minute two of the 20 min walk and the subjects underwent a Positron emission tomography scan immediately after the task. Differences in relative regional metabolism of areas under the tDCS anode and the basal ganglia were calculated and investigated. The results indicated diverse and individualized responses in regions under the anode and consistent increases in some basal ganglia areas. Thus, anodal tDCS targeting the M1 that controls the more-affected leg of PwMS might be capable of affecting remote subcortical regions and modulating the activity of the circuitry connected to these regions.

Research ethics is a core component of undergraduate psychology curricula, typically first encountered in introductory textbooks. Previous analyses of introductory textbooks focused on human research ethics. Given growing concerns about animal research—particularly among college students—we analyzed discussions of animal research ethics in 18 introductory psychology textbooks. Our results revealed that while most textbooks address this topic, defenses of animal use and mentions of oversight account for a majority of content, while discussions of ethics were lacking. We discuss implications of these (...) results and suggest improvements for engaging students to think critically about animal research ethics. (shrink)

Coupledom and notions of intimacy and family formation with one committed partner are hallmarks of family and relationship science. Recent national surveys in the United States and Canada have found that consensually non-monogamous relationships are common, though prevalence of specific types of consensual non-monogamy are unknown. The present research draws on a United States Census based quota sample of single adults to estimate the prevalence of desire for, familiarity with, and engagement in polyamory—a distinct type of consensually non-monogamous relationship where (...) people typically engage in romantic love and sexual intimacy with multiple partners. Results show that 1 out of 6 people desire to engage in polyamory, and 1 out of 9 people have engaged in polyamory at some point during their life. Approximately 1 out of 15 people reported that they knew someone who has been or is currently engaged in polyamory. Among participants who were not personally interested in polyamory, 1 out of 7 indicated that they respect people who engage in polyamory. Few sociodemographic correlates emerged; no differences in prevalence were found based on political affiliation, income, religion, geographic region, or race/ethnicity. Sexual minorities, men, and younger adults reported greater desire to engage in polyamory. Men and people with lower education backgrounds were more likely to have previously engaged in polyamory. Given that emotional and sexual intimacy is an important part of most people’s lives, understanding the varied ways in which people navigate their intimate lives is critical for the fields of relationship, sexuality, and family science.

Are the places that superhuman beings purportedly act and dwell randomly or arbitrarily distributed? Inspired by theoretical work in cognitive science of religion, descriptions of superhuman beings were solicited from informants in 20 countries on five continents, resulting in 108 usable descriptions, including information about these beings’ properties, their dwelling location, and whether they were the target of rituals. Whether superhuman beings are the subject of religious and ritual practices appeared to co-vary in relation to both features of physical geography (...) and cognitive factors. Good gods were more likely the focus of religious practices than evil gods, and where the gods are thought to dwell mattered. If either the being was thought to dwell in a dangerous place or a resource rich place, it was more likely to have practices directed at it. (shrink)

If “Big Gods” evolved in part because of their ability to morally regulate groups of people who cannot count on kin or reciprocal altruism to get along, then powerful gods would tend to be good gods. If the mechanism for this cooperation is some kind of fear of supernatural punishment, then we may expect that mighty gods tend to be punishing gods. The present study is a statistical analysis of superhuman being concepts from 20 countries on five continents to explore (...) whether the goodness of a god is related to its mightiness. Gods that looked more like the God of classical theism and gods that were low in anthropomorphism were more likely to be regarded as morally good and to be the target of religious practices. Mighty gods were not, however, especially likely to punish or to be a “high god.”. (shrink)

ObjectiveTo compare techniques for computing clustering and switching scores in terms of agreement, correlation, and empirical value as predictors of incident cognitive impairment.MethodsWe transcribed animal and letter F fluency recordings on 640 cases of ICI and matched controls from a national epidemiological study, amending each transcription with word timings. We then calculated clustering and switching scores, as well as scores indexing speed of responses, using techniques described in the literature. We evaluated agreement among the techniques with Cohen’s κ and calculated (...) correlations among the scores. After fitting a base model with raw scores, repetitions, and intrusions, we fit a series of Bayesian logistic regression models adding either clustering and switching scores or speed scores, comparing the models in terms of several metrics. We partitioned the ICI cases into acute and progressive cases and repeated the regression analysis for each group.ResultsFor animal fluency, we found that models with speed scores derived using the slope difference algorithm achieved the best values of the Watanabe–Akaike Information Criterion, but with good net reclassification improvement only for the progressive group. For letter fluency, different models excelled for prediction of acute and progressive cases. For acute cases, NRI was best for speed scores derived from a network model, while for progressive cases, the best model used clustering and switching scores derived from the same network model. Combining variables from the best animal and letter F models led to marginal improvements in model fit and NRI only for the all-cases and acute-cases analyses.ConclusionSpeed scores improve a base model for predicting progressive cognitive impairment from animal fluency. Letter fluency scores may provide complementary information. (shrink)

In cognitive science, there is a tacit norm that phenomena such as cultural variation or synaesthesia are worthy examples of cognitive diversity that contribute to a better understanding of cognition, but that other forms of cognitive diversity (e.g., autism, attention deficit hyperactivity disorder/ADHD, and dyslexia) are primarily interesting only as examples of deficit, dysfunction, or impairment. This status quo is dehumanizing and holds back much-needed research. In contrast, the neurodiversity paradigm argues that such experiences are not necessarily deficits but rather (...) are natural reflections of biodiversity. Here, we propose that neurodiversity is an important topic for future research in cognitive science. We discuss why cognitive science has thus far failed to engage with neurodiversity, why this gap presents both ethical and scientific challenges for the field, and, crucially, why cognitive science will produce better theories of human cognition if the field engages with neurodiversity in the same way that it values other forms of cognitive diversity. Doing so will not only empower marginalized researchers but will also present an opportunity for cognitive science to benefit from the unique contributions of neurodivergent researchers and communities.

Brings together cutting-edge research on the use of empirical scientific methods to illuminate traditional and contemporary issues in political philosophy.

Two main uses of categories are classification and feature inference, and category labels have been widely shown to play a dominant role in feature inference. However, the nature of this influence remains unclear, and we evaluate two contrasting hypotheses formalized as mathematical models: the label special-mechanism hypothesis and the label super-salience hypothesis. The special-mechanism hypothesis is that category labels, unlike other features, trigger inference decision making in reference to the category prototypes. This results in a tendency for prototype-compatible inferences because (...) the labels trigger a special mechanism rather than because of any influences they have on similarity evaluation. The super-salience hypothesis assumes that the large label influence is due to their high salience and corresponding impact on similarity without any need for a special mechanism. Application of the two models to a feature inference task based on a family resemblance category structure yields strong support for the label super-salience hypothesis and in particular does not support the need for a special mechanism based on prototypes.

The authors address problems with “compulsory” arbitration clauses in contracts. Specifically, they note that consumers are misguided about their rights in such cases. In addition, arbitration clauses do not allow the press to cover any proceedings that may result. The arbitration clauses in contracts are written in legalese that consumers do not understand. The authors found that even university students had difficulty understanding the information in such clauses. An example of an actual case is included.

Animal and plant species exhibit an astonishing diversity of sexual systems, including environmental and genetic determinants of sex, with the latter including genetic material in the mitochondrial genome. In several hermaphroditic plants for example, sex is determined by an interaction between mitochondrial cytoplasmic male sterility (CMS) genes and nuclear restorer genes. Specifically, CMS involves aberrant mitochondrial genes that prevent pollen development and specific nuclear genes that restore it, leading to a mixture of female (male‐sterile) and hermaphroditic individuals in the population (...) (gynodioecy). Such a mitochondrial‐nuclear sex determination system is thought to be rare outside plants. Here, we present one possible case of CMS in animals. We hypothesize that the only exception to the strict maternal mtDNA inheritance in animals, the doubly uniparental inheritance (DUI) system in bivalves, might have originated as a mitochondrial‐nuclear sex‐determination system. We document and explore similarities that exist between DUI and CMS, and we propose various ways to test our hypothesis. (shrink)

Iris Murdoch was a notable philosopher before she was a notable novelist and her work was brave, brilliant, and independent. She made her name first for her challenges to Gilbert Ryle and behaviourism, and later for her book on Sartre, but she had the greatest impact with her work in moral philosophy—and especially her book The Sovereignty of Good. She turned expectantly from British linguistic philosophy to continental existentialism, but was dissatisfied there too; she devised a philosophy and a style (...) of philosophy that were distinctively her own. Murdoch aimed to draw out the implications, for metaphysics and the conception of the world, of rejecting the standard dichotomy of language into the 'descriptive' and the 'emotive'. She aimed, in Wittgensteinian spirit, to describe the phenomena of moral thinking more accurately than the 'linguistic behaviourists' like R. M. Hare. This 'empiricist' task could be acheived, Murdoch thought, only with help from the idealist tradition of Kant, Hegel, and Bradley. And she combined with this a moral psychology, or theory of motivation, that went back to Plato, but was influenced by Freud and Simone Weil. Murdoch's impact can be seen in the moral philosophy of John McDowell and, in different ways, in Richard Rorty and Charles Taylor, as well as in the recent movements under the headings of moral realism, particularism, moral perception, and virtue theory. This volume brings together essays by critics and admirers of Murdoch's work, and includes a longer Introduction on Murdoch's career, reception, and achievement. It also contains a previously unpublished chapter from the book on Heidegger that Murdoch had been working on shortly before her death, and a Memoir by her husband John Bayley. It gives not only an introduction to Murdoch's important philosophical life and work, but also a picture of British philosophy in one of its heydays and at an important moment of transition.Readership: Students and scholars of philosophy and literature.

Recent arguments claim that behavioral science has focused – to its detriment – on the individual over the system when construing behavioral interventions. In this commentary, we argue that tackling economic inequality using both framings in tandem is invaluable. By studying individuals who have overcome inequality, “positive deviants,” and the system limitations they navigate, we offer potentially greater policy solutions.

The dissemination of models across disciplinary lines has become a phenomenon of interest to philosophers of science. To account for this phenomenon, philosophers have invented two units of analysis. The first identifies to the thing that transfers, model templates. The second identifies the thing to which transferable templates apply, landing zones. There exists a dynamic between the thing that is transferred and the thing to which transferrable templates apply. The use of a transferable template in a new domain requires reconception (...) of domain-specific phenomena. This paper examines two cases of model transfer, the use of the ideal gas law in biology by R.A. Fisher and the use of the virial theorem in chemistry by Richard Bader. These two stories of model transfer in biology and chemistry indicate a dimension to conceptual progress related to this dynamic. Using discourse on model transfer affords philosophers a novel approach for depicting the invention of, for instance, chemical concepts and resulting disputes. (shrink)

A number of authors have suggested that a conditional analysis of dispositions must take roughly the following form: Thing X is disposed to produce response R to stimulus S just in case, if X were exposed to S and surrounding circumstances were auspicious, then X would produce R. The great challenge is cashing out the relevant notion of ‘auspicious circumstances’. I give a general argument which entails that all existing conditional analyses fail, and that there is no satisfactory way to (...) define ‘auspicious circumstances’ just in terms of S, R, and X. Instead, I argue that the auspicious circumstances C for the manifestation of a disposition constitute a third irreducible element of that disposition, and that to pick out (or to ‘individuate’) that disposition one must specify C along with S and R. This enables a new conditional analysis of dispositions that gives intuitively satisfying answers in cases that pose problems for other approaches. (shrink)

Alterations to cognitive function are often reported with depression and anxiety symptoms, yet few studies have examined the same associations with mental well-being. This study examined the association between mental well-being, depression and anxiety symptoms and cognitive function in 1502 healthy adult monozygotic and dizygotic twins, and the shared/unique contribution of genetic and environmental variance. Using linear mixed models, mental well-being was positively associated with sustained attention, inhibition, cognitive flexibility, motor coordination and working memory, whereas depression and anxiety symptoms were (...) associated with poorer sustained attention, inhibition, cognitive flexibility and executive function. Bivariate twin modelling showed well-being shared a small environmental correlation with motor coordination and a small genetic correlation with working memory. Trivariate twin modelling showed well-being shared a small genetic correlation with inhibition, whereas depression and anxiety symptoms shared a small environmental correlation with inhibition. The remaining variance was mostly driven by unique G and/or E variance. Overall, well-being and depression and anxiety symptoms show both independent and shared relationships with cognitive functions but this is largely attributable to unique G or E variance and small shared G/E variance between pairs of variables.

Factors such as subsistence turnover, warfare, or interaction between different groups can be major sources of cultural change in human populations. Global demographic shifts such as the transition to agriculture during the Neolithic and more recently the urbanization and globalization of the twentieth century have been major catalysts for cultural change. Here, we test whether cultural traits such as patri/matrilocality and postmarital migration persist in the face of social upheaval and gene flow during the past 150 years in postcolonial South (...) Africa. The recent history of South Africa has seen major demographic shifts that resulted in the displacement and forced sedentism of indigenous Khoekhoe and San populations. During the expansion of the colonial frontier, the Khoe-San admixed with European colonists and enslaved individuals from West/Central Africa, Indonesia, and South Asia, introducing novel cultural norms. We conducted demographic interviews among Nama and Cederberg communities representing nearly 3,000 individuals across three generations. Despite the history of colonial expansion, and the subsequent incorporation of Khoe-San and Khoe-San-descendant communities into a colonial society with strong patrilocal norms, patrilocality is the least common postmarital residence pattern in our study populations today. Our results suggest that more recent forces of integration into the market economy are likely the primary drivers of change in the cultural traits examined in our study. Birthplace had a strong effect on an individual’s odds of migration, distance moved, and postmarital residence form. These effects are at least partially explained by the population size of the birthplace. Our results suggest that market factors local to birthplaces are important drivers of residence decisions, although the frequency of matrilocal residence and a geographic and temporal cline in migration and residence patterns also indicate the persistence of some historic Khoe-San cultural traits in contemporary groups.

We elucidate the epistemological futility of using concepts such as unconscious thinking in research. Focusing on Newell & Shanks' use of the lens model as a framework, we clarify issues with regard to unconscious-thought theory and self-insight studies. We examine these key points: Brunswikian psychology is absent in UTT; research on self-insight did not emerge to explore the unconscious; the accuracy of judgments does not necessitate the unconscious; and the prescriptive claim of UTT is unfounded.

I develop a distinction between two types of psychological hedonism. Inferential hedonism (or “I-hedonism”) holds that each person only has ultimate desires regarding his or her own hedonic states (pleasure and pain). Reinforcement hedonism (or “R–hedonism”) holds that each person's ultimate desires, whatever their contents are, are differentially reinforced in that person’s cognitive system only by virtue of their association with hedonic states. I’ll argue that accepting R-hedonism and rejecting I-hedonism provides a conciliatory position on the traditional altruism debate, and (...) that it coheres well with the neuroscientist Anthony Dickinson’s theory about the evolutionary function of hedonic states, the “hedonic interface theory.” Finally, I’ll defend R-hedonism from potential objections.

This article proposes an evolution of Edmund Husserl’s transcendental epoché by integrating P. R. Sarkar’s Tantra sádhaná, which engages ipseity as both the subject and the object of consciousness. First, it explores some of the recent philosophical and scientific obstacles that confound the transcendental reduction. Following this, an East-West trajectory for Husserl’s first science of consciousness is examined by combining Sarkar’s 3 shuddhis in pratyáhára, effecting an experience of noumenal consciousness. Combining Husserl’s phenomenology with Sarkar’s spiritual praxis reinvigorates the transcendental (...) epoché and emphasizes practice in a field both undermined by logical positivism and dominated by the scholasticism of Husserl’s protégés. Furthermore, the efficacy of an East-West approach is contextualized in view of Husserl’s admiration of Buddhism and Sarkar’s cognitive cosmology. (shrink)

Charting significant growth in science production over the 20th century in four European Union member states, this neo-institutional analysis describes the development and current state of universities and research institutes that bolster Europe’s position as a key region in global science. On-going internationalization and Europeanization of higher education and science has been accompanied by increasing competition as well as collaboration. Despite the policy goals to foster innovation and further expand research capacity, in cross-national and historical comparison neither the level of (...) R&D investments nor country size accounts completely for the differential growth of scientific productivity. Based on a comprehensive historical database from 1900 to 2010, this analysis uncovers both stable and dynamic patterns of production and productivity in Germany, France, Belgium, and Luxembourg. Measured in peer-reviewed research articles collected in Thomson Reuters’ Science Citation Index Expanded, which includes journals in the fields of Science, Technology, Engineering, Mathematics, and Health, we show the varying contributions of different organizational forms, especially research universities and research institutes. Comparing the institutionalization pathways that created the conditions necessary for continuous and strong growth in scientific productivity in the European center of global science emphasizes that the research university is the key organizational form across countries.

William L. Rowe’s argument against divine freedom has drawn considerable attention from theist philosophers. One reply to Rowe’s argument that has emerged in the recent literature appeals to modified accounts of libertarian freedom which have the result that God may be free even if he necessarily actualizes the best possible world. Though in many ways attractive, this approach appears to lead to the damning consequence of modal collapse i.e., that the actual world is the only possible world. But appearances can (...) be deceiving, and in this paper I argue that the threat of modal collapse dissolves when we consider Alvin Plantinga’s critique of the purportedly Leibnizian notion that God can actualize any possible world, and incorporate the implications of this critique into the divine freedom debate. Developing a suggestion by Edward R. Wierenga, I argue first that the modal collapse objection fails within a Molinist context, and then I extend the discussion beyond that context to show that the objection also fails on the assumption that Molinism is false.

There are many computational problems which are generally “easy” to solve but have certain rare examples which are much more difficult to solve. One approach to studying these problems is to ignore the difficult edge cases. Asymptotic computability is one of the formal tools that uses this approach to study these problems. Asymptotically computable sets can be thought of as almost computable sets, however every set is computationally equivalent to an almost computable set. Intrinsic density was introduced as a way (...) to get around this unsettling fact, and which will be our main focus.Of particular interest for the first half of this dissertation are the intrinsically small sets, the sets of intrinsic density $0$. While the bulk of the existing work concerning intrinsic density was focused on these sets, there were still many questions left unanswered. The first half of this dissertation answers some of these questions. We proved some useful closure properties for the intrinsically small sets and applied them to prove separations for the intrinsic variants of asymptotic computability. We also completely separated hyperimmunity and intrinsic smallness in the Turing degrees and resolved some open questions regarding the relativization of intrinsic density.For the second half of this dissertation, we turned our attention to the study of intermediate intrinsic density. We developed a calculus using noncomputable coding operations to construct examples of sets with intermediate intrinsic density. For almost all $r\in $, this construction yielded the first known example of a set with intrinsic density r which cannot compute a set random with respect to the r-Bernoulli measure. Motivated by the fact that intrinsic density coincides with the notion of injection stochasticity, we applied these techniques to study the structure of the more well-known notion of MWC-stochasticity.prepared by Justin Miller.E-mail: [email protected]: https://curate.nd.edu/show/6t053f4938w.

The elements are X, ω 1 , ω 1 * , C, C * where X is any suborder of the reals of size (...) ω 1 and C is any Countryman line. Third, the Proper Forcing Axiom implies the Singular Cardinals Hypothesis at κ unless stationary subsets of S κ + ω reflect. The techniques are expected to be applicable to other open problems concerning the theory of H(ω 2 ). (shrink)

In this study we examined the applicability of personality measures to assessing God representations, and we explored how the overlap between personality judgments of self and God relate to strength of (dis)belief and closeness to God among atheists and agnostics. Using sample of 1,088 atheists/agnostics, we applied Goldberg’s Big Five bipolar markers as a standardized measure of personality dimensions, along with measures of identity fusion with God, belief strength, and sociosexuality, as this trait has been shown to be relevant in (...) predicting religiosity. Our study revealed that personality measures can be used for research on the personality of supernatural agents. We also found that personality self-assessments were related to the assessments of God personality. Agreeableness was positively related to the perception of emotional stability of God, while conscientiousness and surgency were negatively related to perceived intellect and surgency of god, respectively. Also, intellect of the participants was related negatively to perceptions of God’s emotional stability and intellect. Perceived distance between the assessment of one’s own personality and the personality of God predicted the strength of (dis)belief, thus opening new interpretations into possible sources of belief and disbelief. Finally, echoing previous studies, we found that conscientiousness of God had a negative effect on SOI-R score. (shrink)
