Objections to the HEXACO Model of Personality Structure—and why those Objections Fail

The Importance of Context-Relevance: Entrepreneurial Personality Relates to Entrepreneurial Outcomes Beyond the HEXACO and Dark Triad

Entrepreneurial Personality (EP) is a collection of traits that causes someone to be entrepreneurial, including both an attraction to and success in entrepreneurial activities. Although EP and its inclusion criteria is defined by its relevance to entrepreneurship, research has yet to support that it relates to entrepreneurial outcomes more strongly than extant frameworks of personality, causing uncertainty regarding its theoretical rationale and conceptual foundation. Applying the bandwidth-fidelity dilemma as our theoretical lens, the current article reports two studies to test whether EP relates to entrepreneurial outcomes beyond the HEXACO and Dark Triad dimensions. Using a sample of non-business owners, Study 1 supports that EP explains both more variance than and variance beyond the HEXACO and Dark Triad in outcomes associated with the earlier phases of the entrepreneurial process, such as entrepreneurial goal setting, goal striving, and goal achievement. Using a sample of business owners, Study 2 supports that EP explains both more variance than and variance beyond the HEXACO and Dark Triad in outcomes associated with the later phases of the entrepreneurial process, including entrepreneurial performance and well-being. These results encourage future research on EP by supporting the validity of the personality framework, and we suggest several directions for future research, such as broader applications of the bandwidth-fidelity dilemma.

Nuanced HEXACO: A Meta-Analysis of HEXACO Cross-Rater Agreement, Heritability, and Rank-Order Stability

Most Five-Factor Model (FFM) questionnaire items contain unique variance that is partly heritable, stable, and consensually observable, demonstrates consistent associations with age and sex, and predicts life outcomes beyond higher order factors. Extending these findings to the HEXACO model, we meta-analyzed single-item cross-rater agreement, heritability, and 2-year stability using samples from six countries. We analyzed raw item scores and their residual variance and adjusted the estimates for measurement unreliability. The median cross-rater agreement, heritability, and stability estimates were, respectively, .30, .30, and .57, for raw items and .10, .16, and .39, for item residuals. Adjusted for reliability, the respective medians were .46 and .25 for cross-rater agreement, .46 and .39 for heritability, and .87 and .94 for stability. These results are strikingly consistent with FFM-based findings, providing nondismissible evidence that single items index a partly unique level of the trait hierarchy-personality nuances-with trait properties comparable to those of higher-order traits.

Cheating to benefit others? On the relation between Honesty-Humility and prosocial lies

OBJECTIVE

Among basic personality traits, Honesty-Humility yields the most consistent, negative link with dishonest behavior. The theoretical conceptualization of Honesty-Humility, however, suggests a potential boundary condition of this relation, namely, when lying is prosocial. We therefore tested the hypothesis that the association between Honesty-Humility and dishonesty weakens once lying benefits someone else, particularly so if this other is needy.

METHODS

In two online studies (Study 1: N = 775 in Germany; Study 2: N = 737 in the UK, preregistered), we measured self-reported Honesty-Humility and dishonest behavior in incentivized cheating paradigms in which the beneficiary of participants' dishonesty was either the participants themselves, a "non-needy" other (e.g., another participant), or a "needy" other (e.g., a charity).

RESULTS

We found support for the robustness of the negative association between Honesty-Humility and dishonesty, even if lying was prosocial.

CONCLUSION

Individuals high in Honesty-Humility largely prioritize honesty, even if there is a strong moral imperative to lie; those low in Honesty-Humility, by contrast, tend to lie habitually and thus even if they themselves do not directly profit monetarily. This suggests that (un)truthfulness may be an absolute rather than a relative aspect of Honesty-Humility, although further systematic tests of this proposition are needed.

Moral beacons: Understanding moral character and moral influence

OBJECTIVE

We introduce the concept of moral beacons-individuals who are higher in moral character than their peers and prominent within their social environment-and examine the degree to which moral beacons increase the moral awareness of their peers.

BACKGROUND

Using data from cohorts of students in graduate business education across two universities, we applied theory and methods from organizational behavior, personality psychology, and social networks analysis to test two research questions about moral beacons.

METHOD

We used latent profile analysis of data from personality questionnaires and social network surveys completed by graduate business students at two universities (N = 502) to identify individuals classified as moral beacons. We used peer nominations and an in-class business case discussion exercise to assess moral influence.

RESULTS

Latent profile analysis identified a latent class of moral beacons in our sample. These individuals received more nominations from their peers in end-of-class surveys as guides for moral thought and action and positively impacted the moral awareness of their peers in a discussion of a difficult business case about possible lead poisoning of employees, but did not significantly change their counterparts' moral awareness in a different case.

CONCLUSIONS

These results provide promising initial evidence that moral beacons can be distinguished from their peers by both moral character and social prominence and can act as guides for others, at times encouraging greater consideration of the moral aspects of situations and decisions. As these results are the first of their kind, we encourage further replication and investigations of moral beacons and moral influence in other settings.

Coping, (mal)adaptive personality and identity in young adults: A network analysis

Coping, personality, and identity are three well-known constructs within the field of psychology. Yet, findings regarding how these constructs relate to each other have been inconsistent. The present study employs network analysis to investigate coping, adaptive and maladaptive personality, and identity and how they are related, using data from the Flemish Study on Parenting, Personality, and Development (FSPPD; Prinzie et al., 2003; 1999-current). Young adults (N = 457; 47% male), aged between 17-23 years old, completed a survey on coping, adaptive and maladaptive personality, and identity. Results indicate clear associations between coping and both adaptive and maladaptive personality within the network, suggesting coping and personality are distinct, yet highly related constructs whereas identity proved largely unrelated. Potential implications and suggestions for future research are discussed.

Can eating behaviour traits be explained by underlying, latent factors? An exploratory and confirmatory factor analysis

Eating Behaviour Traits (EBTs) are psychological constructs developed to explain patterns of eating behaviour, including factors that motivate people to (over or under) eat. There is a need to align and clarify their unique contributions and harmonise the understanding they offer for human eating behaviour. Therefore, the current study examined whether 18 commonly cited EBTs could be explained by underlying, latent factors (domains of eating behaviour). An exploratory factor analysis (EFA) was used to identify latent factors, and these factors were validated using a confirmatory factor analysis (CFA). 1279 participants including the general public and members of a weight management programme were included in the analysis (957 females, 317 males, 3 others, 2 prefer not to say), with a mean age of 54 years (median = 57 years, SD = 12.03) and a mean BMI of 31.93 kg/m2 (median = 30.86, SD = 6.00). The participants completed 8 questionnaires which included 18 commonly cited EBTs and the dataset was split at random with a 70/30 ratio to conduct the EFA (n = 893) and CFA (n = 383). The results supported a four-factor model which indicated that EBTs can be organised into four domains: reactive, restricted, emotional, and homeostatic eating. The four-factor model also significantly predicted self-reported BMI and weight change. Future research should test whether this factor structure is replicated in more diverse populations, and including other EBTs, to advance these domains of eating as a unifying framework for studying individual differences in human eating behaviour.

A Richer Vocabulary of Chinese Personality Traits: Leveraging Word Embedding Technology for Mining Personality Descriptors

This study uses a data-driven approach to mine the distribution of personality traits among Chinese people in the Chinese social context. Based on the hypothesis of personality lexicology, word embedding technology was employed in machine learning to mine personality vocabulary from Tencent's word embedding database. More than 10,000 Chinese personality descriptors were extracted and analyzed using Gaussian Mixture Model Cluster and Hierarchical clustering analysis. The data was collected from 658 Chinese people randomly from all parts of China through an online questionnaire method. The results reveal six personality traits in the Chinese context, expanding the personality thesaurus and providing examples to illustrate each trait. The findings coincide with previous research on the five-factor model, which partially describes the personality traits of Chinese people, but does not offer a complete explanation of their typical social behavior patterns. Additionally, the study supports the notion of cultural particularity in personality traits. The approach used in this study offers a richer personality vocabulary than traditional personality mining methods, and word embedding technology captures richer semantic information in Chinese. The six Chinese personality traits identified in this study will also be used to explore how to quantify and evaluate personality traits based on word embedding and personality descriptors.

Compilation and Validation of Two Short Forms to Measure HEXACO Dimensions in Elementary School Children

Personality trait measures for children are rarely based on the HEXACO Model of Personality, although research using this framework could provide important insights into the structure and development of children's personalities. There is no HEXACO measure for elementary school children to date, and existing measures for older children seem inappropriate for this age group (e.g., due to some item content). We thus compiled two HEXACO-based short forms for measuring personality in elementary school children (8-10 years old) via parent reports. We applied a meta-heuristic item sampling algorithm (Ant Colony Optimization) in a training sample with 1,641 parent reports of 122 administered items. We selected a 54-Item Short Form comprising a latent facet structure and an 18-Item Ultra-Short Form comprising a correlated factors model for all six HEXACO dimensions but no facet structure. Both short forms showed good model fit in a holdout sample (n = 411) and sufficiently high re-test correlations after six months. Convergent and divergent validities for maximal performance measures and socio-emotional constructs (also measured six months after the initial personality assessment) were largely in line with theoretical assumptions. Overall, our study provides support for construct, re-test, and (predictive) criterion validity for the selected short forms.

Broad and narrow environmental and genetic sources of personality differences: An extended twin family study

OBJECTIVE

Several personality theories distinguish between rather genetically rooted, universal dispositional traits (DTs) and rather environmentally shaped, more contextualized characteristic adaptations (CAs). However, no study so far has compared different measures of theoretically postulated DTs and CAs regarding their environmental and genetic components while considering differences in measurement abstraction and reliability. This study aims to bridge this gap by testing the assumed differences in the sensitivity to environmental influences based on representative sets of DTs (Big Five and HEXACO domains and facets) and CAs (goals, interests, value priorities, religiousness, and self-schemas).

METHOD

Using intra-class correlations and running extended twin family and spouses-of-twins model analyses, we analyzed a large data set (N = 1967) encompassing 636 twin pairs, 787 parent-offspring dyads, and 325 spouses/partners.

RESULTS

Findings consistently support lower environmentality of DTs compared to CAs. On average, more than half of reliable variance in DTs was genetic, whereas the reverse was found for CAs. Larger environmental components in CAs were primarily attributable to larger individual-specific effects (beyond error of measurement) and factors shared by spouses.

CONCLUSIONS

Findings are discussed against the background of the definitional distinction between DTs and CAs and the value of extended twin family data.

The HEXACO Adjective Scales and Its Psychometric Properties

The HEXACO model divides the space of personality into six main dimensions: Honesty-Humility, Emotionality, eXtraversion, Agreeableness (vs. anger), Conscientiousness, and Openness to Experience. Despite the lexical foundation, no validated adjective-based instruments are available yet. This contribution describes the newly developed HEXACO Adjective Scales (HAS), a 60 adjectives instrument to measure the six main personality dimensions. Study 1 (N=368) proceeds to the first pruning of a large set of adjectives to identify potential markers. Study 2 (N=811) delineates the final list of 60 adjectives and provides benchmarks for the new scales' internal consistency, convergent/discriminant, and criterion validity. Study 3 (N=411) confirms the HAS factorial structure, internal consistency, and criterion validity. The study also provides evidence of temporal stability (test-retest reliability) and convergence between raters (peer/self-evaluation). The HAS shows excellent psychometric properties and constitutes a valuable tool for assessing the HEXACO personality dimensions using adjectives.

Do We Need a Novel Framework for Classifying Psychopathology? A Discussion Paper

Introduction

The ICD-11 and DSM-5 are the leading systems for the classification of mental disorders, and their relevance for clinical work and research, as well as their impact for policy making and legal questions, has increased considerably. In recent years, other frameworks have been proposed to supplement or even replace the ICD and the DSM, raising many questions regarding clinical utility, scientific relevance, and, at the core, how best to conceptualize mental disorders.

Method

As examples of the new approaches that have emerged, here we introduce the Hierarchical Taxonomy of Psychopathology (HiTOP), the Research Domain Criteria (RDoC), systems and network approaches, process-based approaches, as well as a new approach to the classification of personality disorders.

Results and Discussion

We highlight main distinctions between these classification frameworks, largely related to different priorities and goals, and discuss areas of overlap and potential compatibility. Synergies among these systems may provide promising new avenues for research and clinical practice.

Development of an Inconsistent Responding Scale for the HEXACO Personality Inventory-Revised

Inconsistent or careless responding is a significant threat to the validity of self-reported personality data. Using archival samples of undergraduate and community participants, we developed an inconsistent responding scale using items that appear on both the 60- and 100-item versions of the HEXACO Personality Inventory-Revised-two widely used measures of the HEXACO model of personality trait structure. We identified pairs of correlated HEXACO items in Sample 1 and created a total inconsistent responding score by summing absolute differences between each item pair. The Brief Response Inconsistency Evaluation (BRIE) for the HEXACO effectively differentiated between genuine and randomly generated responses across samples. The BRIE also correlated as expected with other measures of careless responding and relevant personality traits (e.g., conscientiousness). Tentative cut scores for the BRIE that appear to provide a reasonable balance between sensitivity and specificity in Sample 1 were investigated. Future research should examine the BRIE with different populations and translations of the HEXACO inventories and further investigate the effectiveness of the recommended cut scores.

A Short Measure of the Big Five Aspects: Development and Validation of the BFAS-40

We present psychometric evidence for the BFAS-40, an abbreviated measure of the Big Five Aspects Scale (DeYoung et al., 2007). In Study 1, we developed the BFAS-40 using metaheuristic algorithms and cross-validated the factor structure of the shortened measure. In Study 2, we demonstrated that the BFAS and BFAS-40 correlate with external criteria in similar ways. In Studies 3 and 4, we provide convergent validity evidence by examining correlations between the BFAS-40 and other measures of typical and clinically relevant personality. Finally, in Study 5, we provide evidence of test-retest reliability as well as additional construct validity evidence. Across these five studies, we demonstrate that the BFAS-40 is a short, reliable, and valid measure of the Big Five Aspects.

HEXACO Personality Factors and their Associations with Facebook use and Facebook Network Characteristics

Personality factors affect the properties of 'offline' social networks, but how they are associated with the structural properties of online networks is still unclear. We investigated how the six HEXACO personality factors (Honesty-Humility, Emotionality, Extraversion, Agreeableness, Conscientiousness and Openness to Experience) relate to Facebook use and three objectively measured Facebook network characteristics - network size, density, and number of clusters. Participants (n = 107, mean age = 20.6, 66% female) extracted their Facebook networks using the GetNet app, completed the 60-item HEXACO questionnaire and the Facebook Usage Questionnaire. Users high in Openness to Experience spent less time on Facebook. Extraversion was positively associated with network size (number of Facebook Friends). These findings suggest that some personality factors are associated with Facebook use and the size of Facebook networks, and that personality is an important influence on both online and offline sociality.

Big Five personality traits and coping strategies of Italian university students during the COVID-19 pandemic first wave

Introduction

Little is known about the role personality traits may have played for university students in diminishing and compensating for the negative impact of COVID-19 in its early phases, promoting adaptive coping. University students represent a population which was consistently obliged to follow social distance rules due to the early shift of many organizations from face-to-face to online learning. Therefore, it is worth exploring whether the Big Five traits acted as risk or protective factors after the outbreak of a disaster such as the COVID-19 pandemic for Italian university students.

Methods

We involved a sample of 2,995 university students who completed an online survey in March 2020. We measured the Big Five personality traits through the Big Five Inventory-2-XS and their coping strategies through the Robust-Pandemic Coping Scale. The latter assessed four COVID-19-related coping dimensions, namely Despair (e.g., including helplessness and feeling lack of control), Aversion (e.g., referring to oppositive strategies), Proactivity (e.g., comprising problem solving and information seeking), and Adjustment (e.g., concerning reappraisal and assertiveness).

Results

Preliminarily, two Linear Mixed Models indicated that university students had higher scores in Conscientiousness, followed by Open-Mindedness, and then Agreeableness. These three traits were, in turn, higher than Extraversion and Negative Emotionality, which did not differ among them. Concerning coping, university students reacted more frequently utilizing adaptive strategies (with Proactivity used more frequently than Adjustment) rather than maladaptive strategies (with Despair higher than Aversion). A Path Analysis examining the relations between the Big Five traits and the four coping dimensions showed that Negative Emotionality can be considered as a risk factor, and that Agreeableness, Conscientiousness, and Open-Mindedness can be conceptualized as protective factors. More interestingly, we found that Extraversion entailed both a risk and a protective role for Italian university students after the outbreak of the COVID-19 pandemic.

Discussion

Notwithstanding limitations, these findings can be the basis for developing disaster preparation and prevention actions, aiming at promoting students' positive coping towards current and future disasters.

Unselfish traits and social decision-making patterns characterize six populations of real-world extraordinary altruists

Acts of extraordinary, costly altruism, in which significant risks or costs are assumed to benefit strangers, have long represented a motivational puzzle. But the features that consistently distinguish individuals who engage in such acts have not been identified. We assess six groups of real-world extraordinary altruists who had performed costly or risky and normatively rare (<0.00005% per capita) altruistic acts: heroic rescues, non-directed and directed kidney donations, liver donations, marrow or hematopoietic stem cell donations, and humanitarian aid work. Here, we show that the features that best distinguish altruists from controls are traits and decision-making patterns indicating unusually high valuation of others' outcomes: high Honesty-Humility, reduced Social Discounting, and reduced Personal Distress. Two independent samples of adults who were asked what traits would characterize altruists failed to predict this pattern. These findings suggest that theories regarding self-focused motivations for altruism (e.g., self-enhancing reciprocity, reputation enhancement) alone are insufficient explanations for acts of real-world self-sacrifice.

Conceptual and methodological issues in the study of the personality-and-culture relationship

Culture-and-personality studies were central to social science in the early 20th century and have recently been revived (as personality-and-culture studies) by trait and cross-cultural psychologists. In this article we comment on conceptual issues, including the nature of traits and the nature of the personality-and-culture relationship, and we describe methodological challenges in understanding associations between features of culture and aspects of personality. We give an overview of research hypothesizing the shaping of personality traits by culture, reviewing studies of indigenous traits, acculturation and sojourner effects, birth cohorts, social role changes, and ideological interventions. We also consider the possibility that aggregate traits affect culture, through psychological means and gene flow. In all these cases we highlight alternative explanations and the need for designs and analyses that strengthen the interpretation of observations. We offer a set of testable hypotheses based on the premises that personality is adequately described by Five-Factor Theory, and that observed differences in aggregate personality traits across cultures are veridical. It is clear that culture has dramatic effects on the thoughts, feelings, and behaviors from which we infer traits, but it is not yet clear whether, how, and in what degree culture shapes traits themselves.

Tracing the evolution of personality cognition in early human civilisations: A computational analysis of the Gilgamesh epic

Assessing evolution of cognitive structures across historical periods has remained challenging in the absence of direct access to humans from the past. Overcoming some of these challenges, we examined shifts in the implicit cognitive structures in the Epic of Gilgamesh, which is one of the earliest surviving pieces of literature, circulating in various versions over a period of approx. 2000 years in ancient Mesopotamia. Using a canonical English translation, we applied natural language processing (NLP) and human coding to extract low-dimensional representations of the implicit personality structure in three different historical epochs. We found systematic shifts over time with increasing complexity and increasing resemblance of contemporary personality models in later periods. We discuss how lexical analyses of ancient texts using trait co-occurrence analyses can provide novel insights on the evolution of human behaviour of relevance for contemporary social and behavioural science and the study of ancient societies.

Dimensional models of personality disorders: Challenges and opportunities

Categorical models of personality disorders have been beneficial throughout psychiatric history, providing a mechanism for organizing and communicating research and treatment. However, the view that individuals with personality disorders are qualitatively distinct from the general population is no longer tenable. This perspective has amassed steady criticism, ranging from inconsequential to irreconcilable. In response, stronger evidence has been accumulated in support of a dimensional perspective that unifies normal and pathological personality on underlying trait continua. Contemporary nosology has largely shifted toward this dimensional perspective, yet broader adoption within public lexicon and routine clinical practice appears slow. This review focuses on challenges and the related opportunities of moving toward dimensional models in personality disorder research and practice. First, we highlight the need for ongoing development of a broader array of measurement methods, ideally facilitating multimethod assessments that reduce biases associated with any single methodology. These efforts should also include measurement across both poles of each trait, intensive longitudinal studies, and more deeply considering social desirability. Second, wider communication and training in dimensional approaches is needed for individuals working in mental health. This will require clear demonstrations of incremental treatment efficacy and structured public health rebates. Third, we should embrace cultural and geographic diversity, and investigate how unifying humanity may reduce the stigma and shame currently generated by arbitrarily labeling an individual's personality as normal or abnormal. This review aims to organize ongoing research efforts toward broader and routine usage of dimensional perspectives within research and clinical spaces.

Disentangling the Association Between the Big Five Personality Traits and Student Achievement: Meta-Analytic Evidence on the Role of Domain Specificity and Achievement Measures

Students’ academic achievement is a central predictor of a long list of important educational outcomes, such as access to higher education and socioeconomic success. Prior studies have extensively focused on identifying variables that are related to academic achievement and an important variable in this context appears to be students’ personality. Notably, although findings from more recent studies suggested that the association between student achievement and personality varies by the subject domain (language vs. STEM) and the type of achievement measure (grades vs. test scores), systematic meta-analytical evidence is still lacking. To address this gap in the educational research literature, we conducted a meta-analysis based on 78 studies, with 1491 effect sizes representing data from 500,218 students and 110 samples from elementary to high school. We used a random-effects model with robust variance estimation to calculate mean effect sizes and standard deviations. We found moderating effects of measure or domain for all five personality traits, with differences in the direction of the effects. Our results highlight the importance of the domain and measure when examining how personality traits relate to academic achievement in school. The combination of subject domain and achievement was also found to be relevant for some of the traits. These findings emphasize that subject domains and types of achievement measures should be explicitly considered when investigating the personality saturation of student achievement. We discuss implications for future research, highlighting that there is no “best” or “more objective” achievement measure but, instead, that achievement measures should be chosen based on the research question of interest.

I enjoy hurting my classmates: On the relation of boredom and sadism in schools

Schools can be a place of both love and of cruelty. We examined one type of cruelty that occurs in the school context: sadism, that is, harming others for pleasure. Primarily, we proposed and tested whether boredom plays a crucial role in the emergence of sadistic actions at school. In two well-powered studies (N = 1038; student age range = 10-18 years) using both self- and peer-reports of students' boredom levels and their sadistic tendencies, we first document that sadistic behavior occurs at school, although at a low level. We further show that those students who are more often bored at school are more likely to engage in sadistic actions (overall r = .36, 95% CI [0.24, 0.49]). In sum, the present work contributes to a better understanding of sadism in schools and points to boredom as one potential motivator. We discuss how reducing boredom might help to prevent sadistic tendencies at schools.

Honesty as a trait

The purpose of this paper is to review recent research about the possibility that some people are more honest than others and about the causes of them being so. We tackle four big questions about the consistency of honest behavior, the content and breadth of trait honesty, the mechanisms underlying trait honesty, and the measurement of trait honesty. Recent research reveals we are only at the beginning states of answering these questions about honesty. Invigorated research is needed to firmly resolve whether individuals differ in honesty and if so, integrate the determining mechanisms and develop strong measurements.

Personality and behavioral dishonesty

The past two decades have seen major developments in the study of behavioral (dis)honesty and its measurement as well as a surge of interest in the location of trait honesty within models of basic personality structure and the role of personality traits in behavioral dishonesty more generally. The present review provides an overview of the corresponding literature with a particular emphasis on recent developments and identifies the research questions for which we now have relatively reliable knowledge as well as those that will require future research.

On the ontology of language: A critique of trait theory

In this article, we present a comparative analysis of the ontological assumptions about language at play within structural linguistics and trait theory. The ontological discussions demonstrate a fundamental incongruence between trait theory’s aim of description and its assumptions about language. This discussion guides a broader analysis of the structuring effect of the ontology of language within the study of subjectivity. We also develop the proposition that an integrative reading of structural linguistics and the phenomenology of speaking can be a constructive way to think coherently about language as system and language as subjectivity by insisting on speech as corporeal intention and reference and, thereby, lived.

Personality in a naturally occurring strong situation: Unique effects of HEXACO traits on COVID-19 mitigation

The first Italian lockdown during COVID-19 pandemic constituted an example of strong situation. Under this context, we investigated associations of HEXACO personality with COVID-19 mitigation behaviors (self-reported hygiene, distancing, going out). We tested unique associations through regularized regressions and out-of-sample prediction after establishing the best level of analysis (HEXACO traits, facets, items). Personality always explained out-of-sample variance over and above demographics, COVID-related knowledge, concern, impacts, and goals. Hygiene and distancing were best predicted by HEXACO traits, whereas facets constituted the best level for the prediction of going out. In general, honesty-humility (trait or facets) was the clearest predictor of safer behaviors. Results corroborate the relevance of personality even in strong situations, as well as its importance for COVID-19 mitigation.

Locating the Dark Triad in a Multidimensional Personality Space

The Dark Triad traits of Psychopathy, Machiavellianism, and Narcissism should be clearly recognizable within a multidimensional personality space. Two such personality spaces were investigated in this study: HEXACO (Honesty-Humility, Emotionality, Extraversion, Agreeableness, Conscientiousness, and Openness to Experience); and the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) space (Extraversion, Neuroticism, Activity, Sensation Seeking, and Aggressiveness). Our sample comprised 289 participants (137 males, 145 females, 7 unspecified) who completed these three questionnaires: HEXACO-60, ZKA-PQ/SF, and the SD3, assessing the Dark Triad. We reduced the dimensionality of each space to that of a 2D representation using Smallest Space Analysis (SSA). Three research questions guided the data analysis: (a) Do the HEXACO and ZKA-PQ SSA spaces conform to the structure of a radex? (b) Will these spaces remain invariant following the entry of the Dark Triad traits into the analyses? (c) Where will the Dark Triad traits be located in each SSA space? For ZKA-PQ space, the structure was clearly indicative of a radex, both prior to entering the Dark Triad traits into the analysis, and subsequent to this. Psychopathy and Machiavellianism were in close proximity in the Aggressiveness region; Narcissism was positioned at the common origin. In contrast, HEXACO space did not conform to a radex; furthermore, the presence of the Dark Triad traits distorts this 2D SSA space.

The organic diet effect on person perception

The organic halo effect describes how individuals tend to ascribe positive attributes such as low-calorie content to organic food. In this contribution, we extend the organic halo effect to the inferences individuals make about organic food consumers regarding basic personality traits. In a first study (N = 608), we tested whether describing a person as a regular (vs. rare) consumer (man vs. woman) who buys and regularly (vs. rarely) consumes organic food influences inferences of the Big Six personality traits and other characteristics. Results showed that a person depicted as a regular consumer of organic food is perceived as more honest, more agreeable, more conscientious, and more open. A second study (N = 214) with a similar procedure tested whether the effects from the previous study were due to the frequency information by manipulating the type of food (organic vs. conventional) and the high-frequency information (present vs. absent). We also included a measure of the Dark Triads traits to see whether this effect only applies to positive traits. Results generally confirmed the previous pattern. However, organic consumers were also judged as more narcissistic. Merging the two studies, we also showed that the organic halo effect was stronger for participants who frequently consume organic food. We discuss results in light of the large effect sizes and the evidence suggesting that while positive valence plays a role, it cannot explain the trait inferences' extent and specificity.

Sharing Money With Humans Versus Computers: On the Role of Honesty-Humility and (Non-)Social Preferences

Does giving behavior in economic games reflect true prosocial preferences or is it due to confusion? Research showing that trait Honesty-Humility accounts for giving behavior suggests the former, whereas research showing that participants give money to a computer might suggest the latter. In three preregistered, well-powered studies, we examined the relation of Honesty-Humility with behavior in the Dictator Game (Study 1, N = 468) and Public Goods Game (Studies 2 and 3, each N = 313), while participants interacted either with humans (“social game”) or with a computer (“non-social game”). We found that (a) decisions in the non-social game predicted decisions in the social game, supporting the confusion hypothesis; (b) the effect of Honesty-Humility differed within and between games; and (b) participants who gave money to the computer reported acting as if they were playing with humans. Overall, the studies suggest that both prosocial preferences and confusion underlie giving behavior.

Toward a Model of Personality Competencies Underlying Social and Emotional Skills: Insight From the Circumplex of Personality Metatraits

In recent years, there has been a growing interest in social and emotional skills (SES) both in the scientific literature and in social practice. The paper presents an overview of the ways of understanding what SES are and the catalogs thereof. There are some attempts in the literature to organize these catalogs within the Big Five traits that for a long time was claimed to be the most sound model of basic orthogonal dimensions of personality. However, further research on personality structure revealed that two metatraits can be found above the Big Five traits. These two metatraits form the basis of the Two Factor Model of personality, which was later developed into the Circumplex of Personality Metatraits. It turned out that in certain aspects models based on metatraits have a greater theoretical potential than those based on the Big Five traits. The paper presents a proposal for describing SES from the perspective of the Circumplex of Personality Metatraits rather than the Big Five. In this framework, we distinguish the concept of personality competences that underlie and organize many specific SES and identify the core personality competencies on the basis of the Circumplex of Personality Metatraits model.

Effect of Personality Traits on Banner Advertisement Recognition

This article investigates the effect of personality traits on the attitude of web users towards online advertising. Utilizing and analyzing personality traits along with possible correlations between these traits and their influence on consumers’ buying behavior is crucial not only in research studies; this also holds for commercial implementations, as it allows businesses to set up and run sophisticated and strategic campaign designs in the field of digital marketing. This article starts with a literature review on advertisement recall and personality traits, which is followed by the procedure and processes undertaken to conduct the experiment, construct the online store, and design and place the advertisements. Collected data from the personality questionnaire and the two experiment questionnaires (pre and post-test) are presented using descriptive statistics, and data collected from the eye-tracking are analyzed using visual behavior assessment metrics. The results show that personality traits and especially honesty–humility can prove to be a predictive force for some important aspects of banner advertisement recognizability.

COVID-19 vermijdingsgedrag: Het belang van persoonlijkheid en de relatie met toename in thuiswerken

De COVID-19 pandemie kan opgevat worden als een situatie waarin een specifieke vorm van trekactivatie plaatsvindt waarbij persoonlijkheid de kans op besmetting met het COVID-19 virus kan beïnvloeden. In dit onderzoek wordt gekeken naar de relatie tussen HEXACO persoonlijkheid en COVID-19 vermijdingsgedrag, dat wil zeggen het omgaan met de bedreiging die uitgaat van de pandemie en de mate waarin men zich schikt naar de COVID-19 gedragsregels. Daarnaast wordt gekeken in hoeverre COVID-19 vermijdingsgedrag een relatie heeft met een toename in thuiswerken. In een gestratificeerde Nederlandse steekproef van 932 volwassenen (waarvan N = 526 werkten) in september 2020 werd gevonden dat – naast leeftijd – hoge emotionaliteit en consciëntieusheid en lage extraversie de voornaamste unieke persoonlijkheidsvoorspellers van COVID-19 vermijdingsgedrag waren. Daarnaast voorspelden een selectie van zes facetten (angstigheid, sociabiliteit, ijver, weetgierigheid, onconventionaliteit en proactiviteit) COVID-19 vermijdingsgedrag beter dan de HEXACO domeinschalen. De belangrijkste voorspellers van een toename in thuiswerken waren het hebben van een kantoorbaan en een hoge opleiding. Het onderzoek maakt duidelijk dat individuele verschillen een grote rol spelen in hoe men omgaat met de pandemie, maar dat verschillen in opleiding en type baan het meest bepalend zijn voor de mate waarin men is gaan thuiswerken.

Academic Majors and HEXACO Personality

Self-reports on the HEXACO-PI-R scales were examined in relation to academic majors in post-secondary education ( N > 73,000). Openness to Experience showed the largest mean differences across academic major areas, with the Visual/Performing Arts and Humanities areas averaging higher and Health Sciences and Business/Commerce averaging lower. Emotionality showed the second largest differences, with the Engineering and Physical Sciences/Math areas averaging lower and Visual/Performing Arts averaging higher; these differences in Emotionality became smaller in within-sex analyses. In addition, Extraversion tended to be higher for Business/Commerce and lower for Physical Sciences/Math, while Honesty-Humility was lower for Business/Commerce. The facet-level analyses provided additional detail, as facet scales in the same domain sometimes showed considerably different means within a given academic major area. In one case, Visual/Performing Art majors averaged lower in Prudence, but higher in Perfectionism, even though both facets belong to the Conscientiousness domain.

Aversive Personality and COVID-19

Abstract. The Coronavirus Disease 2019 (COVID-19) has strongly affected individuals and societies worldwide. In this review and meta-analysis, we investigated how aversive personality traits – that is, relatively stable antisocial personality characteristics – related to how individuals perceived, evaluated, and responded to the COVID-19 pandemic. Across 34 studies with overall 26,780 participants, we found that people with higher scores in aversive personality traits were less likely to perceive guidelines and restrictions to curb the spread of the virus as protective ([Formula: see text] = −.11), to engage in health behaviors related to COVID-19 ([Formula: see text] = −.16), and to engage in non-health-related prosocial behavior related to COVID-19 ([Formula: see text] = −.14). We found no consistent relation between aversive personality and negative effect regarding the pandemic. The results thus indicate the importance of aversive personality traits in understanding individual differences with regard to COVID-19.

A Plea for Studying Qualitative Individual Differences by Default

I see great potential in the approach proposed by Rouder and Haaf. First, using an example from unethical decision making, I demonstrate that considering quantitative individual differences alone can make us overlook important psychological phenomena that are only visible at the individual level. Thus, the study of quantitative individual differences should, by default, be complemented by investigation of qualitative individual differences. Second, having powerful tools to study qualitative individual differences in cognition has great potential to advance personality science. Recently, personality psychologists are increasingly working towards obtaining a better understanding of the processes that underlie the expression of personality in behavior. The toolbox provided by Rouder and Haaf may add to this research in meaningful ways.

Personality Psychology

Personality psychology, which seeks to study individual differences in thoughts, feelings, and behaviors that persist over time and place, has experienced a renaissance in the last few decades. It has also not been reviewed as a field in the Annual Review of Psychology since 2001. In this article, we seek to provide an update as well as a meta-organizational structure to the field. In particular, personality psychology has a prescribed set of four responsibilities that it implicitly or explicitly tackles as a field: (a) describing what personality is-i.e., what the units of analysis in the field are; (b) documenting how it develops; (c) explaining the processes of personality and why they affect functioning; and (d) providing a framework for understanding individuals and explaining their actions, feelings, and motivations. We review progress made over the last 20 years to address these four agendas and conclude by highlighting future directions and ongoing challenges to the field. Expected final online publication date for the Annual Review of Psychology, Volume 73 is January 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Exploring the stability of HEXACO-60 structure and the association of gender, age, and social position with personality traits across 18 countries

OBJECTIVES

The present paper tests the cross-national stability of the HEXACO-60 structure across 18 countries from four continents. Gender and age differences across countries will be examined. Finally, this is the first study to explicitly analyze the relationships between the HEXACO and social position.

METHOD

Ten thousand two hundred and ninety eight subjects (5,410 women and 4,888 men) from 18 countries and 13 languages were analyzed. Confirmatory factor analysis techniques were used to test configural, metric and scalar invariance models. Congruence coefficients with the original structure of the HEXACO-60 were computed for every culture. Effect sizes of gender, age, and social position factors across countries were also computed.

RESULTS

HEXACO-60 demonstrates configural and metric invariance, but not scalar invariance. Congruence coefficients show a great equivalence in almost all countries and factors. Only Emotionality presents a large gender difference across countries. No relevant effect of age is observed. A profile of high scores on Honesty-Humility, Extraversion, Conscientiousness, and Openness to Experience, and low scores on Emotionality increases the likelihood of achieving a higher social position, although the effect sizes are small.

CONCLUSIONS

HEXACO-60 is a useful instrument to conduct personality trait research and practice around the world. Implications of gender, social position, and country differences are discussed.

The finer details? The predictability of life outcomes from Big Five domains, facets, and nuances

Associations between personality traits and life outcomes are usually studied using the Big Five domains and, occasionally, their facets. But recent research suggests these associations may be driven by the items (reflecting personality nuances) chosen to measure these traits. Using a large dataset (N = 6126), we examined associations with 53 self-reported outcomes using domains, facets and items (markers for nuances), training and validating models in different sample partitions. Facets better predicted outcomes than domains (on average, 18.0% versus 16.6% of variance explained), but items provided the most accurate predictions (on average 20.9%). Removing domain and facet variance from items had no effect on their predictive validity, suggesting that outcome-related information was often in items' unique variances (i.e., nuance-specific). Item-based prediction also showed the highest discriminant validity. These observations, replicating previous findings, suggest that personality traits' valid associations with outcomes are often driven by narrow personality nuances.

On the Comparability of Basic Personality Models: Meta-Analytic Correspondence, Scope, and Orthogonality of the Big Five and HEXACO Dimensions

Models of basic personality structure are among the most widely used frameworks in psychology and beyond, and they have considerably advanced the understanding of individual differences in a plethora of consequential outcomes. Over the past decades, two such models have become most widely used: the Five Factor Model (FFM) or Big Five, respectively, and the HEXACO Model of Personality. However, there is no large-scale empirical evidence on the general comparability of these models. Here, we provide the first comprehensive meta-analysis on (a) the correspondence of the FFM/Big Five and HEXACO dimensions, (b) the scope of trait content the models cover, and (c) the orthogonality (i.e., degree of independence) of dimensions within the models. Results based on 152 (published and unpublished) samples and 6,828 unique effects showed that the HEXACO dimensions incorporate notable conceptual differences compared to the FFM/Big Five dimensions, resulting in a broader coverage of the personality space and less redundancy between dimensions. Moreover, moderator analyses revealed substantial differences between operationalizations of the FFM/Big Five. Taken together, these findings have important theoretical and practical implications for the understanding of basic personality dimensions and their assessment.
