The Dark Triad,the Big Five,and the HEXACO model

The “Dark Triad” of Machiavellianism, Narcissism, and psychopathy has received much research attention since the seminal article of Paulhus and Williams (2002). The introduction of the Dark Triad came shortly after the discovery of a six-dimensional model of personality characteristics, now called the HEXACO model. One of the HEXACO factors—Honesty–Humility—is essentially equivalent (at its opposite pole) to the common element shared by the Dark Triad variables. We suggest that the emergence and popularity of the Dark Triad reflect the importance of these characteristics and their underrepresentation in five-dimensional models of personality. We note that optimal prediction and understanding of criterion variables is better achieved using the HEXACO factors than using an ad hoc combination of the Big Five and a Dark Triad composite.     

Dichotomous Thinking and Personality Traits: From the Viewpoints of the Big Five and HEXACO1,2

Dichotomous thinking is a feature of certain personality traits, such as the Dark Triad and Cluster B personality disorders, which commonly reflect a fast life history strategy. The Big Five and HEXACO personality models are useful for understanding the personality structure and individual differences in life history strategy. Our study aimed to shed light on the propensity for dichotomous thinking using the framework of the Big Five and HEXACO personality models. Participants (n = 229) completed the Dichotomous Thinking Inventory, the 60-item HEXACO Personality Inventory – Revised, and the Ten-Item Personality Inventory. We examined correlations between dichotomous thinking and each domain of the Big Five and HEXACO personality models, and then computed multiple correlations predicting total and dimensional scores on the propensity for dichotomous thinking with scores on the Big Five and HEXACO personality traits. Results indicated that dichotomous thinking tendency is characterized by the set of low Agreeableness and Honesty–Humility. This study suggests that dichotomous thinking has antagonistic characteristics and a linkage to the fast life history strategy.     

Personality,the Dark Triad and violence

Aggression involves using force to dominate a situation, whereas violence uses force to do intentional harm. Previous research suggests the Dark Triad underlies much anti-social behaviour, and is associated with aggression. We extend this work to examine whether Dark Triad constructs predict self-reported violence. The Dark Triad, measured using the SD3, was examined in relation to normal personality traits as indexed by the HEXACO, which comprises a general Big Five structure with the addition of an Honest–Humility dimension. We also measured impulsivity using the I-7. A sample of 159 adults completed the measures. Principal Components Analysis revealed Machiavellianism, psychopathy and violence loaded on the same factor, which also had negative loadings for HEXACO domains of Honesty–Humility and Agreeableness. Narcissism loaded on a separate factor which was also defined by Extraversion. Hierarchical regression analyses found Agreeableness a more powerful predictor of violence than psychopathy or Machiavellianism, both of which showed a trend to this association; narcissism had no effect. Agreeableness emerged as the strongest negative predictor of violence, and exclusively explained the majority of variance in violence scores. Findings are discussed regarding the centrality of low agreeableness as a driving force behind the Dark Triad and the constructs it predicts.     

Honesty–Humility and the HEXACO Structure of Religiosity and Well-Being

Past research has shown that general and intrinsic religiosity is related to higher Big Five Agreeableness, Conscientiousness and, to some extent, Extraversion. With the rise of the six-factor HEXACO (Honesty–Humility, Emotionality, eXtraversion, Agreeableness, Conscientiousness, Openness) model of personality, however, a more differentiated look at religiousness and personality is called for. It has been suggested that religiosity is more associated with Honesty–Humility than with Agreeableness. The new personality factor, Honesty–Humility has also been shown to have null or weak relations with happiness. In 5 studies involving 1375 participants from Iran, Poland, and Malaysia, the relations of Honesty–Humility and other HEXACO dimensions to religious orientation and well-being outcomes were investigated. As expected, Honesty–Humility was one of the strongest personality correlate of religiosity. Higher scores on religiousness were also associated with Agreeableness, Conscientiousness, and to some extent, Extraversion showing that the main personality characteristics of religiosity are consistent across religious contexts and personality models. Relations of Honesty–Humility to psychological well-being scales were consistently positive and stronger than its relations to subjective well-being measures, suggesting that Honesty–Humility may not be “bad” for pleasure attainment and pain avoidance, but it is definitely “good” for living a virtuous, fully functioning life.     

A sixth personality domain that is independent of the Big Five domains: The psychometric properties of the HEXACO Personality Inventory in a Japanese sample

We investigated the reliability of the HEXACO‐Personality Inventory (HEXACO‐PI) using the NEO Five‐Factor Inventory (NEO‐FFI) and the International Personality Item Pool (IPIP) Big Five scales in a Japanese sample of 492 respondents (mean age = 20.4 years). The psychometric properties of the HEXACO‐PI were examined and found to be satisfactory. The results of the factor analysis showed that the six hypothesized personality domains were found independently. A total of 307 participants responded to the NEO‐FFI and the IPIP Big Five scales. The results showed that the five domains of the HEXACO model corresponded to the Five‐Factor domains and were relative to the Big Five personality domains as a whole, but the sixth domain, Honesty‐Humility, showed weak to moderate correlations with some factors of the NEO‐FFI and the IPIP Big Five scales. These results suggest that the Honesty‐Humility domain is independent of the five fundamental personality factors and that the HEXACO‐PI is a useful and reliable questionnaire for investigating personality structure in cross‐cultural and other context.     

The discriminant validity of honesty-humility: A meta-analysis of the HEXACO,Big Five,and Dark Triad

We perform a meta-analysis of almost 400 studies to assess honesty-humility’s relationships with the (H)EXACO, Big Five, and Dark Triad dimensions. We meta-analytically support that honesty-humility shares a modest amount of variance with the (H)EXACO and Big Five dimensions, although it is more strongly associated with Big Five agreeableness than HEXACO agreeableness. Honesty-humility does, however, very strongly relate to the Dark Triad, and the unreliability-corrected correlation of honesty-humility with Machiavellianism approaches levels expected in tests of convergent validity. Most relationships significantly differed based on the measure and facet. We urge future authors to investigate the facets shared between honesty-humility and Machiavellianism as well as assess differences of the HEXACO against the Big Five and Dark Triad (B5 + D3) when studied together.     

Predicting integrity with the HEXACO personality model: Use of self‐ and observer reports

Recent research has suggested that a six‐dimensional model of personality called the HEXACO framework may have particular value in organizational settings because of its ability to predict integrity‐related outcomes. In this series of studies, the potential value of the HEXACO factor known as Honesty‐Humility was further examined. First, the empirical distinctness of this construct from the other major dimensions of personality was demonstrated in a high‐stakes personnel selection situation. Second, Honesty‐Humility was found to predict scores on an integrity test and a business ethical decision‐making task beyond the level of prediction that was possible using measures based on a traditional Big Five model of personality. This finding was also observed when Honesty‐Humility was assessed by familiar acquaintances of the target persons. The applicability of the HEXACO model within industrial and organizational psychology was then discussed.     

The HEXACO model of personality structure and indigenous lexical personality dimensions in Italian,Dutch, and English

We correlated the scales of the HEXACO Personality Inventory (HEXACO-PI) with adjective scale markers of personality factors previously obtained in indigenous lexical studies of personality structure in the Italian, Dutch, and English languages. Self-ratings were obtained from samples of 327 Italian, 161 Dutch, and 214 English-speaking Canadian participants. Results showed that each of the six HEXACO variables—including Honesty–Humility—correlated strongly with its hypothesized six-factor adjective scale counterpart in all three languages. In each case, convergent correlations were substantially stronger than discriminant correlations. Because the HEXACO model was developed without prior knowledge of the indigenous Dutch and English lexical factors, the results suggest that the HEXACO model of personality structure can be extended to the personality lexicons of those languages.     

More than the Big Five: Egoism and the HEXACO model of personality

Egoism is a personality trait that is associated with self‐enriching and self‐centred behaviours. Research has suggested that egoism lies beyond the Big Five personality factors. Recently, the HEXACO model of personality has been proposed as an alternative to the Big Five model. In three studies, the relation between the HEXACO Personality Inventory and egoism, conceptualized using three different questionnaires (DPQ Egoism, SPI Egotism and the Egoism Scale), is investigated. In all three studies, the HEXACO Honesty–Humility factor scale was the most important predictor of egoism. Additionally, in two studies in which FFM measures were used, the HEXACO Personality Inventory explained more variance in egoism than did the FFPI (Study 2) and the NEO‐PI‐R (Study 3).

The relations of gratitude to religiosity,well-being,and personality

The relations of gratitude toward God and dispositional gratitude with well-being and personality were investigated, in an Iranian sample. As expected, gratitude was associated with higher scores on happiness, life satisfaction, psychological well-being, and the Big Five factors of personality. Dispositional gratitude out-predicted religious gratitude in relation with well-being. A second study confirmed the results in a second sample of Iranian Muslims, and in a sample of Polish Christians, providing cross-cultural evidence that the dispositional gratitude is a unique predictor of well-being. Positive links between gratitude and Honesty–Humility provided additional construct validity for these variables, as personality dimensions representing the bases of reciprocal altruism.     

Personality and prejudice: Extension to the HEXACO personality model

We modelled the associations between the HEXACO dimensions of personality, Social Dominance Orientation (SDO), Right‐Wing Authoritarianism (RWA) and prejudice towards dangerous, derogated and dissident groups (N = 454 undergraduates). Consistent with a Big‐Five model, low Openness to Experience predicted RWA and therefore dangerous and dissident group prejudice. As predicted, low Emotionality (and Openness) rather than Agreeableness predicted SDO and therefore derogated and dissident group prejudice. Comparison with meta‐analytic averages of Big‐Five data supported expected similarities and differences in the association of Big‐Five and HEXACO models of personality with ideology. Finally, Honesty‐Humility simultaneously predicted increases in RWA but decreases in SDO, and thus opposing effects on prejudice. These opposing effects have gone unidentified in research employing Big‐Five models of personality structure. Copyright © 2010 John Wiley & Sons, Ltd.     

The HEXACO Personality Inventory: Validation and Psychometric Properties in the Serbian Language

The aim of this research is to validate the HEXACO model of personality in the Serbian language through psychometric validation of the 100–item version of the HEXACO–PI–R. The research was conducted on 2 independent samples, the first comprising 1,217 participants from a community sample (55.5% females; average age = 31.77 years), and the second 345 undergraduate students (65% females; average age = 21 years). Besides the HEXACO–PI–R, 2 questionnaires were applied for the purposes of convergent validation: the Big Five Plus Two (BF+2), measuring 7 lexical personality dimensions (applied in Sample 1), and the Big Five Inventory (BFI; applied in Sample 2). Factor structure of the HEXACO–PI–R is in line with model assumptions. Convergent validity is good, whereby Extraversion, Openness to Experience, and Conscientiousness are highly correlated to their BFI and BF+2 counterparts. Honesty–Humility is most closely related to Negative Valence (BF+2), Emotionality to BFI Neuroticism, and Agreeableness to BF+2 Aggressiveness and BFI Agreeableness. The results point to the satisfactory validity of the HEXACO model and its measure in the Serbian language.     

God,the good life,and HEXACO: the relations among religion,subjective well-being and personality

The relations among religiousness, subjective well-being (SWB) and the HEXACO (Honesty–Humility, Emotionality, eXtraversion, Agreeableness, Conscientiousness, Openness) model of personality were studied in a Muslim population. As expected, Extraversion and Honesty-Humility factors were the strongest correlates of SWB and religiosity, respectively. Religiosity also correlated with higher levels of SWB, and explained variance in SWB beyond personality factors, showing that religion is a unique predictor of well-being. Results have been discussed within the religious orientation paradigm, and the HEXACO model of personality structure.     

Broad versus narrow traits: Conscientiousness and honesty–humility as predictors of academic criteria

Recent research has suggested that the six‐dimensional personality model, and especially the dimension Honesty–Humility/Integrity, adds incremental validity to the prediction of important criteria. We expected both this dimension and the dimension Conscientiousness to explain incremental variance in two academic criteria, namely grade point average (GPA) and counterproductive academic behaviour (CAB). In addition, we expected the more specific, so‐called narrow traits of Conscientiousness and Honesty–Humility/Integrity to be stronger predictors of academic criteria than the broad traits. To test these expectations, two studies were conducted using the HEXACO Personality Inventory Revised (HEXACO‐PI‐R) and the Multicultural Personality Test—Big Six (MPT‐BS). The results confirmed our expectations and suggest that academic criteria may be predicted with greater accuracy by focusing on the narrow traits of Conscientiousness and Honesty–Humility/Integrity.

Unpacking “evil”: Claiming the core of the Dark Triad

Understanding the nature of “evil” has been challenging for a number of reasons. A productive psychological approach to this problem has been to study antisocial traits associated with negative outcomes. One such approach has grouped together three antisocial personalities known as the “Dark Triad”: Machiavellianism, Narcissism, and Psychopathy. Researchers have proposed various models to account for the common core of these antisocial personalities – a core that might well be considered the psychological equivalent of the core of “evil” – and these models have not been directly compared, to date. We conducted two studies (total N > 700) to compare the utility of the various models using Canonical Correlation Analyses (CCAs). Results confirm that the HEXACO personality model (and, in particular, the Honesty–Humility factor) is not only the most theoretically parsimonious model, it also best accounts for the empirical overlap between these constructs that represents the core of the Dark Triad. Results also support the idea that the core of the Dark Triad represents an alternative life history strategy.     

Are Dishonest Extraverts More Harmful than Dishonest Introverts? The Interaction Effects of Honesty‐Humility and Extraversion in Predicting Workplace Deviance

Honesty‐Humility, one of the six major personality dimensions included in the HEXACO model of personality structure, has previously been found to show negative correlations with workplace deviance. In this study, we hypothesised that Extraversion would moderate the relationship between Honesty‐Humility and workplace deviance. In particular, we posited that the relation between Honesty‐Humility and workplace deviance would be stronger among employees who are high on Extraversion than among those low on Extraversion. The hypothesis was tested using three different samples across Australia, Canada, and the Netherlands. It was found in two of the three samples that high levels of Extraversion did indeed amplify the relationship between (low) Honesty‐Humility and workplace deviance. Results suggest a potentially important role for multiplicative effects of personality variables on workplace criteria.     

Comparing the Eysenck and HEXACO Models of Personality in the Prediction of Adult Delinquency

Drawing from self and peer reports of personality, the present study compares the structures of the HEXACO and Eysenck models of personality and the models' capacity to predict self reported acts of delinquency. Correlations amongst scales revealed that Psychoticism captures elements of both HEXACO Emotionality and Conscientiousness. The Eysenck Lie scale correlated positively with both self and peer reported HEXACO Honesty–Humility and Conscientiousness, suggesting that this validity scale includes substantive variance relating to the latter factors. Regression analyses of personality data from both rater sources revealed that Honesty–Humility and Psychoticism were strong predictors of delinquency that independently offered substantial incremental validity. For self reports, the Extraversion and Lie scales were also strong unique predictors of delinquency. Copyright © 2011 John Wiley & Sons, Ltd.     

Active versus reactive cooperativeness in Borderline Psychopathology: A dissection based on the HEXACO model of personality

The concept of personality disorders (PDs) is shifting from categorical to dimensional, conceptualizing PDs as maladaptive variants of basic personality traits. The Agreeableness trait in the Five Factor Model of personality classically represents dispositional cooperativeness, which is associated with PDs characterized by interpersonal impairments. However, recent research designates two separate dispositional tendencies: active and reactive cooperativeness. Using the HEXACO model of personality we assessed traits representing these tendencies (Honesty–Humility and Agreeableness) and investigated their relation to Borderline features in 602 individuals. Borderline features were associated with low Agreeableness scores, representing low reactive cooperation, entailing a tendency to retaliate. Yet, there was no association with Honesty–Humility, implying intact active cooperativeness and non-exploitation. These findings extend prior results on the relation between Borderline PD and basic personality dimensions driving prosocial behavior. Implications for the understanding of interpersonal problems in PDs and the refinement of existing therapies are discussed.     

Situational Affordances for Prosocial Behaviour: On the Interaction Between Honesty‐Humility and (Perceived) Interdependence

Individual differences in prosocial behaviour are well‐documented. Increasingly, there has been a focus on the specific situations in which particular personality traits predict prosocial behaviour. HEXACO Honesty‐Humility—the basic trait most consistently linked to prosocial behaviour in prior studies—has been found to predict prosociality most strongly in situations that afford the exploitation of others. Importantly, though, it may be the subjectively perceived situation that affords the behavioural expression of a trait. Following this reasoning, we tested the proposition that Honesty‐Humility would predict prosocial behaviour more strongly in situations characterised by, and perceived to contain, two dimensions of interdependence that can afford exploitation: high conflict and high power. However, across a series of incentivised economic games and two large experience sampling studies, we only found inconsistent evidence for the association between Honesty‐Humility and prosocial behaviour. Furthermore, the link between Honesty‐Humility and prosociality was neither conditional on objective interdependence nor on subjective perceptions of interdependence. Nonetheless, perceptions of conflict and power tracked objective properties of economic games and were related to prosocial behaviour in the lab and field. Future research should take individuals' subjective understanding of situations into account, which may also help understand the (generalisability of the) effect of Honesty‐Humility on prosocial behaviour. © 2019 The Authors.
