Previous research has established that higher levels of trait Honesty-Humility (HH) are associated with less dishonest behavior in cheating paradigms. However, only imprecise effect size estimates of this HH-cheating link are available. Moreover, evidence is inconclusive on whether other basic personality traits from the HEXACO or Big Five models are associated with unethical decision making and whether such effects have incremental validity beyond HH. We address these issues in a highly powered reanalysis of 16 studies assessing dishonest behavior in an incentivized, one-shot cheating paradigm (N = 5,002). For this purpose, we rely on a newly developed logistic regression approach for the analysis of nested data in cheating paradigms. We also test theoretically derived interactions of HH with other basic personality traits (i.e., Emotionality and Conscientiousness) and situational factors (i.e., the baseline probability of observing a favorable outcome) as well as the incremental validity of HH over demographic characteristics. The results show a medium to large effect of HH (odds ratio = 0.53), which was independent of other personality, situational, or demographic variables. Only one other trait (Big Five Agreeableness) was associated with unethical decision making, although it failed to show any incremental validity beyond HH.

Based on lexical studies, the HEXACO (honesty-humility, emotionality, extraversion, agreeableness, conscientiousness, and openness to experience) model of personality has been proposed as a model of basic personality structure that summarizes individual differences in six broad trait dimensions. Although research across various fields relies on the HEXACO model increasingly, a comprehensive investigation of the nomological net of the HEXACO dimensions is missing entirely. Thus, it remains unclear whether each HEXACO dimension accounts for individual variation across theoretically relevant outcome criteria. We close this gap through a large-scale meta-analytic investigation, testing whether each HEXACO dimension is uniquely linked to one broad and theoretically relevant outcome domain. Results from 426 individual meta-analyses, 436 independent samples, and 3,893 effect-size estimates corroborate this unique mapping. Specifically, honesty-humility maps onto the outcome domain of exploitation, emotionality onto insecurity, extraversion onto sociality, agreeableness versus anger onto obstruction, conscientiousness onto duty, and openness to experience onto exploration. Overall, the current investigation provides a comprehensive empirical test of the (breadth of) content captured by the HEXACO dimensions and allows for a broad specification of the nomological net of the HEXACO model overall.

[Article Retracted] To verify the association between personality traits and academic performance in a university setting, we collected the grade point average (GPA) and six personality characteristics (honesty-humility, emotionality, extraversion, agreeableness, conscientiousness, and openness to experience) of 349 students at a university in China. According to the results, there were positive associations between GPA and honesty-humility, emotionality, extraversion, agreeableness, conscientiousness, and openness to experience. Additionally, honesty-humility, extraversion, agreeableness, and openness to experience explained 30.72% of the variance in GPA. On the basis of the above findings, two conclusions can be made: First, undergraduates' GPA is associated with these six personality traits; second, undergraduates' honesty-humility, extraversion, agreeableness, and openness to experience may help to explain the variance in their GPA.

The above article has been retracted by agreement between the publisher of this journal, Scientific Journal Publishers Limited, the journal's Editor-in-Chief, Dr. Robert A. C. Stewart, and Managing Editor, Alexandra Cheyne, and the submitting author, Longlong Zhao. Concerns were raised by a reader about the reliability of the dataset, and after investigation and analysis of the item-level dataset by external reviewers and journal editors, discrepancies were revealed that cannot be explained by sampling errors or naturally occurring fluctuations. These anomalies in the Zhao data suggest that both the data and resulting conclusions cannot be considered reliable. For this reason, retraction was agreed upon.

Thanh Ngoc Dan Nguyen, Ho Chi Minh City Open University, Ho Chi Minh City, 70000, Vietnam, Email thanh.nnd@ou.edu.vnPurpose: This study aimed to analyze the influence of narcissism on self-esteem and social media addiction. In addition, it highlights the consequences of social media addiction through internal factors such as self-esteem and external factors such as life satisfaction. It also examined the regulatory role of personality traits in this context.Participants and Methods: Conducted in Ho Chi Minh City, it surveyed 426 Generation Z individuals aged 13- 26 spending over two hours daily on social media, using convenience sampling. Data analysis and reliability assessment were done with SPSS 29, and SmartPLS 4 evaluated the linear structural model.Results: The study has demonstrated that narcissism among Generation Z significantly influences life satisfaction. The results indicate that narcissism plays a crucial role in determining the self-esteem of Generation Z. Furthermore, individuals exhibit varying levels of narcissism, which are positively related to various online social activities. Therefore, high levels of narcissism are likely to lead to social media addiction. Those who exhibit symptoms of social media addiction tend to have lower self-esteem because they perceive social media as a safe space where they can express themselves. However, each individual possesses unique personality traits, and this study has proven that specific personality traits such as Agreeableness and Openness impact the life satisfaction of Generation Z.Conclusion: The study investigated how narcissism, self-esteem, and social media addiction affect life satisfaction among Generation Z, exploring their complex interplay and mental health implications. It emphasized Gen Z's widespread social media engagement and addiction risks, impacting mental health and emotional satisfaction. Additionally, it highlighted the influence of personality traits on life satisfaction. The examination scrutinized the intricate relationship between self-esteem and narcissism, stressing its nuances, especially among Generation Z.

We investigated the putative redundancy of the Dark Tetrad (specifically, Machiavellianism-psychopathy and sadism-psychopathy) through an examination of the differences between correlations with self-reported narrowband personality traits. In addition to measures of the Dark Tetrad, participants in four studies completed measures of various narrowband traits assessing general personality, aggression, impulsivity, Mimicry Deception Theory, and Reinforcement Sensitivity Theory. Results generally supported empirical distinctions between Machiavellianism and psychopathy, and between sadism and psychopathy. Machiavellianism significantly differed from psychopathy across correlations for nine of 10 traits (Study 1), 8 of 25 facets (Study 2), aggression (Study 3), 12 of 25 facets (Study 3), four of five facets (Study 4), impulsivity (Study 4), and five of six facets (Study 4). Sadism significantly differed from psychopathy across correlations with five of 10 traits (Study 1), eight of 25 facets (Study 2), reactive aggression (Study 3), 10 of 25 facets (Study 3), three of six facets (Study 4), impulsivity (Study 4), and three of six facets (Study 4). Our findings challenge the claims that Machiavellianism and psychopathy, as well as sadism and psychopathy, as currently measured, are redundant.

NOABSTRACTThe main aim of this study was to examine the effect of the HEXACO domains and triarchic psychopathy dimensions on interpersonal and organisational deviant workplace behaviour.The Workplace Deviance Measure, HEXACO-PI-R and Triarchic Psychopathy Measure were applied to a sample of 429 workers recruited from employees of several IT organisations and education staff working in higher education.Results showed that honesty-humility and agreeableness significantly predicted both interpersonal and organisational workplace deviance, and agreeableness showed significant effects on interpersonal workplace deviance. Openness to experience was unrelated to both interpersonal and organisational workplace deviance, but extraversion positively predicted organisational deviance. All triarchic dimensions (boldness, meanness, and disinhibition) showed significant effects on both interpersonal and organisational workplace deviance.Findings indicate that honesty-humility, agreeableness, and conscientiousness significantly enhance the probability of developing positive relationships with co-workers. Triarchic psychopathy features demonstrate considerable maladaptive potential, consequently presenting a significant risk factor for the development of positive workplace interactions.

There is evidence that different types of irrational thinking and beliefs are significant predictors of questionable and maladaptive COVID-19 related health practices. In this study, we investigated the role of two under-researched types of irrational thinking, more typical for a clinical setting: irrational beliefs defined in Rational Emotive Behavior Therapy (REBT) and attachment anxiety and avoidance. We investigated whether REBT irrational beliefs, attachment dimensions, and conspiracy mentality mediated the relationship between personality traits, on the one side, and COVID-19 health behaviors, on the other. We proposed that HEXACO personality traits, and especially Disintegration (proneness to psychotic-like experiences) predicted irrational thinking and beliefs, which in turn predicted higher susceptibility to questionable health practices. Structural equation modeling on a sample of 287 participants from the general population, showed that Disintegration was related to REBT irrational beliefs, attachment dimensions, and conspiracy mentality, highlighting the important effect of Disintegration on irrational thinking and beliefs. Conspiracy mentality mediated the effects of Disintegration to low adherence to recommended health behaviors--RHB, and greater use of pseudoscientific practices--PSP. Attachment anxiety mediated the relationship between high Disintegration, high Emotionality (E), and low Honesty (H), and lower adherence to RHB. REBT irrational beliefs and attachment avoidance did not mediate the relationship between personality traits and COVID-19 health behaviors.

Personality factors, such as the Dark Tetrad personality factors (Machiavellianism, narcissism and sadism) relate to greater online trolling. Other personality factors, such as the Big Five Personality factors, honesty–humility and negative social potency, may also play a role in cyberbullying, which is an aggressive behavior similar to trolling. The purpose of this study was to predict Facebook trolling behavior based on personality factors. A total of 139 participants completed a survey on their online behavior and personality factors. Online trolling behavior positively correlated with sadism, psychopathy and Machiavellianism, and negatively correlated with agreeableness, conscientiousness and honesty–humility. A hierarchical linear regression showed that sadism, Machiavellianism and negative social potency were the only unique predictors of online trolling behavior. Trolling was unrelated to the frequency of Facebook use and the frequency of commenting. Enjoyment of trolling fully mediated the relationship between Machiavellianism and the trolling behavior. The results thus suggested that Facebook trolling behaviors may be motivated by enjoying the manipulation of others.

Investors’ personality traits and psychological biases play a crucial role in the decision-making process and risk-taking behavior of investors. The emotional and psychological factors impact the decision-making, giving rise to biases. These biases make investors make irrational decisions, which signifies the need for this study. This study aims to assess investors’ personalities using HEXACO model and its interaction with biases and financial risk tolerance. The data of 530 retail investors in India, who had more than 2 years of investing experience in the stock market, were collected. The study considered the HEXACO model since it captures all dimensions of personality that are not considered in the commonly used Big Five Model (BFM). The result of structural equation modeling and mediation analysis shows that the ‘honesty-humility’ trait significantly affects overconfidence bias. The mediation analysis of biases between traits and financial risk tolerance showed complete, partial, and no mediation effect depending on the nature of prejudice. Clear distinction of personality traits into ‘virtue traits’ and ‘character traits’ can be observed. This clear distinction paves the way for employing the HEXACO model in future studies.
