Those who (enjoy to) hurt: The influence of dark personality traits on animal- and human directed sadistic pleasure

BACKGROUND AND OBJECTIVES

Sadistic pleasure - gratuitous enjoyment from inflicting pain on others - has devastating interpersonal and societal consequences. The current knowledge on non-sexual, everyday sadism - a trait that resides within the general population - is scarce. The present study therefore focussed on personality correlates of sadistic pleasure. It investigated the relationship between the Dark Triad traits, and both dispositional and state-level sadistic pleasure.

METHODS

N = 120 participants filled out questionnaires to assess their level of Dark Triad traits, psychopathy subfactors, and dispositional sadism. Then, participants engaged in an animal-directed task in which they were led to believe that they were killing bugs; and in a human-directed task where they could ostensibly noise blasts another participant. The two behavioral tasks were administered within-subjects, in randomized order. Sadistic pleasure was captured by increases in reported pleasure from pre-to post-task.

RESULTS

All Dark Triad traits related to increased dispositional sadism, with psychopathy showing the strongest link. The coldheartedness psychopathy subscale showed a unique combination with both self-reported sadism and increased pleasure following bug grinding.

LIMITATIONS

Predominantly female and student sample, limiting generalizability of findings.

CONCLUSIONS

Out of all Dark Triad components, psychopathy showed the strongest link with gaining pleasure from hurting others. The results underscore the differential predictive value of psychopathy's subcomponents for sadistic pleasure. Coldheartedness can be considered especially disturbing because of its unique relationship to deriving joy from irreversible harm-infliction (i.e. killing bugs). Our findings further establish psychopathy - and especially its coldheartedness component - as the most adverse Dark Triad trait.

Is Doing Good Good Enough? A Motivation, Action, Sacrifice, and Temptation (MAST) View of Moral Praiseworthiness

We present the Motivation, Action, Sacrifice, and Temptation (MAST) view of moral praiseworthiness and evaluate four components shaping judgments of an actor's morality: (a) How did the person act? (b) Why did the person act? (c) Did the person sacrifice something when acting? and (d) Was the person tempted to avoid the sacrifice? Across multiple moral domains, we evaluate moral impressions of hypothetical actors who acted ostensibly morally under different motivational, sacrificial, and temptational conditions. Across four studies (total N > 1,200) and 150 morally relevant scenarios, all components shaped moral impressions, with motivational purity having the strongest impact. Exploring motivation more deeply via Self-Determination Theory, we found effects of internalized (vs. externalized) motivations. Broadly speaking, judges prefer actors to act automatically and in an idealized manner rather than with deliberation and effort. This work address questions that have fascinated philosophers, psychologists, and laypeople, advancing understanding of moral impression formation.

Giving Meaning to the Dark Triad: Comparison of Different Factor Structures of the Dirty Dozen Through Eight Regions of the World

The traits of the dark triad (narcissism, psychopathy, and Machiavellianism) capture the individual differences in the aversive personality. The dark triad has shown significant relations with behaviors that affect people's lives. One of the best-known instruments to assess the dark triad is the Dirty Dozen. However, controversy continues over the use of one general dark triad score or, conversely, three different scores. This study aimed to investigate the factor structure of the Dirty Dozen across eight global regions. There were 11,477 participants in 49 countries grouped into eight regions. Different factor structures were studied using confirmatory factor analyses. Both the three-dimensional models and the bifactor models (symmetrical or traditional and non-symmetrical or bifactor-[S - 1]) showed a good fit to the data. The bifactor-(S - 1) models (with psychopathy or Machiavellianism as the reference factors) show adequate fit to the data, supported by the coherence of the factorial loadings and the bifactor indices. Regarding measurement invariance for both models, configural, metric, and scalar invariance were satisfied. The results indicate that it is not clear whether a psychopathy or Machiavellianism reference factor predominates in the Dirty Dozen. For both models, templates are provided to obtain standardized scores for applied researchers in the eight studied world regions until future studies offer a greater amount of validity evidence for this instrument.

Cognitions in antisocial personality and their association with "dark" traits

Unlike the cognitions associated with depressive symptoms, little is known about those associated with antisocial personality and with its related traits ("dark traits"). Using the scrambled sentences task, an instrument from depression research, we investigated cognitions such as justifications (external blaming for one's behavior) and harm to others (based on the notion that some of these individuals enjoy harming or humiliating others) that we hypothesized may be prevalent in those high in antisocial personality traits. Confirming our hypothesis, these cognitions were associated with ratings on different antisocial personality scales and with antisocial and detachment scores in the alternative model of personality disorders of the DSM-5 (AMPD) in three non-clinical samples, but not with depressive symptoms or neuroticism. Cognitions including harm to others were differentially associated with high sadism. These findings empirically characterize classes of cognitions that are shared by individuals with antisocial tendencies, and that differ from those associated with depressive symptoms.

Canada's Medical Assistance in Dying System can Enable Healthcare Serial Killing

The Canadian approach to assisted dying, Medical Assistance in Dying (MAiD), as of early 2024, is assessed for its ability to protect patients from criminal healthcare serial killing (HSK) to evaluate the strength of its safeguards. MAiD occurs through euthanasia or self-administered assisted suicide (EAS) and is legal or considered in many countries and jurisdictions. Clinicians involved in HSK typically target patients with the same clinical features as MAiD-eligible patients. They may draw on similar rationales, e.g., to end perceived patient suffering and provide pleasure for the clinician. HSK can remain undetected or unconfirmed for considerable periods owing to a lack of staff background checks, poor surveillance and oversight, and a failure by authorities to act on concerns from colleagues, patients, or witnesses. The Canadian MAiD system, effectively euthanasia-based, has similar features with added opportunities for killing afforded by clinicians' exemption from criminal culpability for homicide and assisted suicide offences amid broad patient eligibility criteria. An assessment of the Canadian model offers insights for enhancing safeguards and detecting abuses in there and other jurisdictions with or considering legal EAS. Short of an unlikely recriminalization of EAS, better clinical safeguarding measures, standards, vetting and training of those involved in MAiD, and a radical restructuring of its oversight and delivery can help mitigate the possibility of abuses in a system mandated to accommodate homicidal clinicians.

Personality factors and pandemic-related behaviors

Purpose

The purpose of the current study was to determine whether there are personality differences (the HEXACO model, narcissism, sadism, compassion for others) in mask-wearing, social distancing, and hoarding.

Findings

Those who always wore masks were significantly higher in compassion for others and significantly lower in sadism compared to those who did not always wear masks. Those who always socially distanced (compared to those who did not) were significantly higher in openness, compassion for others, and conscientiousness. Those who hoarded were significantly lower in agreeableness than those who did not hoard.

Conclusion

Perhaps physicians may use information to boost states of altruistic-type traits (agreeableness, compassion for others) while educating patients during visits in order to increase the likelihood of receiving vaccinations or booster shots.

A multi-study investigation assessing the potential redundancy among the Dark Tetrad using a narrowband trait approach

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.

Emotional Regulation of Displaced Aggression in Provocative Situations among Junior High School Students

This study investigated the emotion regulation effect of displaced aggression among junior high school students after provocation through two experiments. Experiment 1 examined the effect of displaced aggression on the negative and positive emotions of junior high school students after low- and high-level provocation. The results showed that only after high-level provocation did individuals experience a significant decrease in negative emotions and a significant increase in positive emotions after engaging in displaced aggression. Experiment 2 explored the effect of aggressive intensity on negative and positive emotions after provocation. The results indicated that, in terms of changes in positive emotions, low-intensity aggression showed a significant increase in positive emotions after aggression. Regarding changes in negative emotions, both low-intensity aggression and high-intensity aggression resulted in significant decreases in negative emotions after aggression. In conclusion, this research showed that, in highly provocative situations, displaced aggression among junior school students, especially low-intensity displaced aggression, could increase positive emotions and decrease negative emotions. These results support the emotional regulation theory of aggression. However, considering that displaced aggression violates social norms, efforts should be made to avoid individuals regulating their emotions through displaced aggression, instead guiding them toward using more appropriate methods for emotional regulation in future research and practical applications.

Do Dark Humour Users Have Dark Tendencies? Relationships between Dark Humour, the Dark Tetrad, and Online Trolling

Humour and antisocial behaviour on the internet are under-researched. Online spaces have opened a gateway for new ways to express unrestrained humour (e.g., dark humour) and ways to behave antisocially (e.g., online trolling). The tendencies and motivations of those engaging with such humour and behaviour are yet to be clearly established and understood. The present study aimed to fill this gap by exploring the interplay between dark humour, online trolling, and dark personality traits. Participants (N = 160) completed an online survey consisting of trait scales to assess the Dark Tetrad, dark humour, and online trolling, as well as two online trolling tasks (enjoyment and ability) and two dark humour meme tasks (enjoyment and ability). The results confirmed relationships between the Dark Tetrad and the dark humour trait, and several Dark Tetrad traits were related to the enjoyment of and ability to produce dark humour. Furthermore, dark humour and online trolling were closely related. The findings also revealed that online trolls did not enjoy being trolled but did enjoy trolling, and this ability to troll is underpinned by sadism. These findings illustrate the potential dark psychological motivations for using dark humour, demonstrate that online trolling is infused with darker forms of humour, and provide deeper insights into online trolls.

Is "sadistic pleasure" a contrived process of signaling one's antagonism?

OBJECTIVE

Sadistic pleasure presumably incorporates processes that support an authentic enjoyment of others' pain. However, antagonism confirmation theory, grounded in social-psychological theorizing on identity maintenance and the notion of ego-syntonicity, suggests that individuals higher in sadism report greater pleasure in response to others' pain because such reports are immoral responses that confirm their self-views. This alternative conception has yet to be tested.

METHOD

In two preregistered experiments (total N = 968), participants completed measures of sadism, read about situations involving others' pain, and rated their pleasure. We manipulated the extent to which pleasure from others' pain could be used to signal morality or antagonism.

RESULTS

We found that relatively sadistic people indicated greater pleasure across the studies but, like relatively non-sadistic people, they altered their pleasure ratings to signal greater morality or less antagonism.

CONCLUSIONS

The findings fail to support antagonism confirmation theory, but they support recent perspectives on sadism that suggest that sadistic people may occasionally care about seeming moral (or not seeming antagonistic) and that sadism may be somewhat ego-dystonic in this respect.

The dark side of personality functioning: associations between antisocial cognitions, personality functioning (AMPD), empathy and mentalisation

Introduction

With the introduction of the new psychiatric diagnostic manuals, personality functioning has gained new prominence. Several studies have reported consistent findings that individual showing high levels of antisocial features are associated with alterations in interpersonal functioning domains such as empathy and mentalisation. The focus of the current study (N = 198) is to examine antisocial cognitions, as measured by the Scrambled Sentences Task (SST), and to what extent this approach can help to better understand the relationship between antisocial traits and personality functioning/empathy.

Method

We implemented a hypothesis-driven approach using logistic regression and a data-driven approach using machine learning to examine distinct but related measures of personality functioning as predictors of antisocial cognitions.

Results

Antisocial cognitions were associated with low interpersonal functioning as expected, but only when not adjusting for antisocial traits, which accounted for almost all the association. The data-driven analysis revealed that individual items assessing empathic concern in personality functioning scales (as opposed to the whole scores) explained low antisocial cognitions even when adjusting for antisocial traits.

Discussion

Antisocial cognitions appear to be associated to two distinct traits, the antisocial and a specific type of personality functioning. This finding is discussed in terms of the possible distinction between two motivational forces: to harm others/prioritize one's advantage, and to help suffering others.

Initial tweet valence, abuse volume, and observer Dark Tetrad characteristics influence perceptions of female celebrity abuse on Twitter

Research into relationships between victim-generated content, abuse received, and observer characteristics when considering Twitter abuse has been limited to male victims. We evaluated participant perceptions of female celebrity victims and abuse received on Twitter. We used a 3 (Initial Tweet Valence; negative, neutral, positive) × 2 (Abuse Volume; low, high) repeated measures design and online survey method. Participants were shown tweets generated by six female celebrities, counterbalanced such that each participant saw each celebrity in one Valence-Volume condition. Stimuli were presented across six 'lists' such that celebrity 'victims' could be rotated across Valence-Volume pairings. Participants rated-per target stimulus-the level of blame attributable to the victim and the perceived severity of the incident. Furthermore, participants were asked to complete a Dark Tetrad scale-measuring their Machiavellianism, Narcissism, Psychopathy, and Sadism. Analyses determined that victim-blaming was influenced by victim Initial Tweet Valence (greater victim-blaming associated with more-negative content) and observer Machiavellianism. Perceived severity was influenced by victim Initial Tweet Valence, Volume of Abuse received, and observer Machiavellianism. Results were consistent with previous research involving male celebrity victims. Further research is needed to understand the contributions of participants' hostile and benevolent sexism, as well as the role of victim attractiveness.

The Gray Nine and Parallel Personality Patterns: Big Five, Dark Tetrad, and a "Well-Rounded Personality"

The vast literature on personality psychology generally focuses on neutral or socially beneficial personality traits such as the Five-Factor model (e.g., agreeableness, conscientiousness) or "dark" traits such as Machiavellianism, narcissism, psychopathy, and everyday sadism. However, the current synthesis of the literature indicates that the distinction between benign, malign, and neutral personality traits and facets is partly misguided. In fact, there are many objective and subjective measures that indicate that high agreeableness is not beneficial, while moderate grandiose narcissism is. Many, if not all of the traits are rather gray and socially and personally desired outcomes indicate that people who aim for a well-rounded personality should typically be clustered in the middle of the various personality spectrums. In addition, many of the personality traits are characterized by parallel patterns of good/bad relations to social and personal outcomes.

The differential effect of psychopathy on active and bystander trolling behaviors: the role of dark tetrad traits and lower agreeableness

This study aimed to develop the Global Assessment of Active Trolling and Passive Bystanderism (GAATPB) scale and investigate the influence of personality traits on trolling behaviors. Focusing on the Dark Tetrad (DT) traits and agreeableness, the present study examined their associations and predictive utility on active trolling and passive bystanderism. Participants were recruited from social networking sites (SNSs), and eligibility criteria included active SNS usage and engagement in online interactions. A total of 797 healthy adult students participated in the study, with data from 300 used for the initial exploratory factor analysis (EFA) and the remaining 497 (Mage = 22.25 years, SD = 3.37) for the subsequent analyses. Results indicated a significant correlation between DT traits and agreeableness across both active trolling and passive bystanderism, revealing a shared personality profile. Hierarchical multiple regression analyses showed that narcissism, Machiavellianism, and trait sadism were predictors of active trolling, with psychopathy being the strongest predictor. However, psychopathy did not emerge as a predictor for passive bystanderism. The study also highlighted that DT traits mediated the relationship between lower agreeableness and overall trolling behavior, suggesting that trolling manifests from lower agreeableness through the instigation of callous-unemotional, manipulative, and self-centered traits inherent in DT.

Personality Traits, Ideology, and Attitudes Toward LGBT People: A Scoping Review

This scoping review investigates the existing literature regarding personality traits, ideology, gender roles, and attitudes toward LGBT people. The review was conducted through PubMed and Web of Science databases. After establishing inclusion- and exclusion criteria, 12 studies published between 2013 and 2023 were reviewed, three themes (personality traits, gender roles and differences, and political ideology) were identified through thematic analysis. Several of the studies reported a relation between the personality traits Openness to Experience, Agreeableness and Conscientiousness, and homo- and transnegative attitudes. In particular, lower levels of Agreeableness, high levels of Conscientiousness, and lower levels of Extraversion were related to prejudice. The Dark Triad, especially the antagonistic traits Psychopathy and Machiavellianism, had a strong association with homo- and transnegativity. Multiple studies showed a connection between negative attitudes and ideological views. Especially right-wing authoritarianism (RWA) and social dominance orientation (SDO) were strong predictors of negative attitudes toward LGBT people. The majority of the studies also reported a significant gender difference in attitudes, with men being more prone to exhibit prejudice toward LGBT people than women. There are practical implications of this review relating to interventions which may target the prevention of homo and trans-negative attitudes, promoting inclusion and integration.

Can Forced-Choice Response Format Reduce Faking of Socially Aversive Personality Traits?

Self-report assessments are the standard for personality measurement, but motivated respondents are able to manipulate or fake their responses to typical Likert scale self-report. Although progress has been made in research seeking to reduce faking, most of it has focused on normative personality traits such as those measured by the five factor model. The measurement of socially aversive personality (e.g., the Dark Triad) is less well-researched. The negative aspects of socially aversive traits increase the opportunity and motivation of respondents to fake typical single-stimulus self-report assessments underscoring the need for faking resistant response formats. A possible way to reduce faking that has been explored in basic personality research is the use of the forced-choice response format. This study applied this method to socially aversive traits and illustrated best practices to create new multidimensional forced-choice and single-stimulus measures of socially aversive personality traits. Results indicated that participants were able to artificially alter their scores when asked to respond like an ideal job applicant, and counter to expectations, the forced-choice format did not decrease faking. Our results indicate that even when best practices are followed, forced-choice format is not a panacea for respondent faking.

When Kinks Come to Life: An Exploration of Paraphilic Behaviors and Underlying Predictors

Paraphilia is defined as a condition in which sexual excitement relies on fantasizing about and/or participating in unusual sexual behavior. Although recent studies have assessed the concordance between paraphilic interests and paraphilic behaviors, few studies have studied which individual traits and demographics predict engaging in paraphilic behaviors, or the level of concordance between arousal and behavior. The current study replicated and expanded Joyal and Carpentier's 2022 study. We assessed concordance between paraphilic arousal and behavior. Further, we assessed the impact of Dark Tetrad traits, impulsivity, social desirability and demographic variables on engaging in paraphilic behaviors using self-report questionnaires in a sample from the general population and FetLife. Finally, we were interested in whether these individual differences moderated the concordance between arousal and behavior. Results indicated high concordance between paraphilic arousal and behavior for all paraphilias except pedophilia and hebephilia. Younger, male participants were more likely to engage in various paraphilias than women and older participants. Machiavellianism was linked with lower paraphilic behavior, particularly impulsive or risky ones. Psychopathy predicted engaging in more deviant or illegal paraphilias, whereas sadism only showed an association for engaging in frotteurism and narcissism was not a predictor for engaging in any paraphilia. For several paraphilias, individual traits moderated the effect of arousal on behavior. Implications of these findings and future directions are discussed.

Social appearance anxiety among the dark tetrad and self-concealment

This study analyzed the effects of the Dark Tetrad (narcissism, Machiavellianism, psychopathy, sadism) and self-concealment on social appearance anxiety. Empirical investigations on which personality traits influence social appearance anxiety are yet missing. In this study, a sample of N = 1186 Chinese students performed a questionnaire-based survey assessing different personality facets and social appearance anxiety tendencies. Measures included the Narcissistic Personality Inventory, the Levenson Self-Report Psychopathy Scale, the Machiavellian Personality Scale, the Short Sadistic Impulse Scale, the Self-concealment Scale, and the Social Appearance Anxiety Scale. The results of the multiple regression analysis showed that psychopathy, Machiavellianism, sadism, and self-concealment positively predicted social appearance anxiety and narcissism negatively predicted social appearance anxiety. Machiavellianism, psychopathy, sadism, and self-concealment were positive predictors of social appearance anxiety, whereas narcissism was a negative predictor. These findings provide insight into the complex nature of the Dark Tetrad and their influence on social appearance anxiety.

Validation of the Italian version of the Dark Tetrad at Work scale

This study presents and validates the Italian adaptation of the Dark Tetrad at Work (DTW) scale, an instrument for assessing four socially aversive personality traits (narcissism, Machiavellianism, psychopathy and sadism) in the context of the workplace. A total of 300 Italian-speaking participants (50% female, M age = 32 years ± 9.2) and 253 English-speaking participants (38% female, M age = 39 years ± 12.1) were recruited via an online survey platform. The Italian-speaking sample was used to test the factorial structure, reliability and criterion-related validity of the Italian version of the DTW, whereas the English-speaking sample was used to test cross-language measurement invariance. Results from confirmatory factor analysis showed that the original four-factor model provided the best fit to the data. The Italian DTW scale demonstrated acceptable internal consistency, with reliability coefficients of ω = .77 for narcissism, ω = .80 for Machiavellianism, and ω = .81 for both psychopathy and sadism. Concurrent associations between the DTW scales and negative and positive workplace outcomes supported the criterion validity of the scale. Machiavellianism, psychopathy, and sadism positively correlated with counterproductive work behaviors and workplace bullying, and negatively with organizational citizenship behaviors and affective organizational commitment. In contrast, narcissism exhibited a unique pattern: It correlated positively with positive workplace behaviors and negatively with counterproductive behaviors toward the organization, but it was also found to be a significant predictor of workplace bullying. This finding may reflect multidimensional nature of narcissism, but a note of caution is warranted in interpreting this result, as all measurements relied on self-report instruments, introducing the possibility of socially desirable associations influencing the outcomes. Finally, the comparison with the English sample established configural, full metric and partial scale invariance, allowing for valid cross-language comparisons between Italian and English-speaking populations in the future. Preliminary Italian normative data were provided to offer a benchmark for the interpretation of DTW values. This study provides a reliable and valid instrument tailored to the Italian workforce, enhancing our understanding of dark personality traits within organizational contexts and providing organizations with an effective means to address and manage dark personality traits for a healthier workplace culture.

The Dark Tetrad: analysis of profiles and relationship with the Big Five personality factors

The Dark Tetrad (DT) is composed of the traits of Narcissism, Machiavellianism, Psychopathy, and Sadism. Most studies analyzing the DT have employed a variable-centered approach, analyzing the traits separately. In the present study, we treat DT as a whole, adopting a person-centered approach. We analyzed different homogeneous subgroups of individuals characterized by specific DT profiles, aiming to examine their relationship with Big Five personality factors. A sample of 1149 participants (50.1% women, 18-79 years) completed The Short Dark Triad and the Assessment of Sadistic Personality instrument to assess DT, while the Mini-IPIP was used to assess the Big Five personality factors. Cluster analysis yielded five groups: Narcissism, Machiavellianism, Mean DT, Low DT, and High DT group. The main results showed that the High DT group was distinguished by higher levels of extraversion and lower levels of agreeableness and conscientiousness (compared with the Low DT group). Moreover, the Narcissism group was characterized by higher scores on emotional stability, openness to experience, and extraversion. Finally, distribution according to gender varied across DT groups (more men than women in the High DT group and the opposite in the Low DT group). Limitations and future lines of research are discussed.

Dominance Analysis of Bright and Dark Dispositional Predictors of Socially Desirable Responding

Although the role of so-called dark traits in the prediction of maladaptive behavior has seen a large increase in interest by researchers, the Big Five still maintain their ubiquity in the prediction of most behaviors. This study uses measures of the Dark Tetrad and the Big Five personality traits to predict a very specific form of maladaptive behavior: the impression management form of socially desirable responding. In regression-based dominance analysis, results suggest that not all of the Big Five nor the Dark Tetrad provide statistically significant incremental validity but as a block, the Big Five dominate the Dark Tetrad in the prediction of the purposeful misrepresentation of one's self to others on self-report inventories. More specifically, four of the Big Five as well as the traits of Machiavellianism and sadism from the Dark Tetrad are significant predictors of impression management.

Sadism in the context of intergroup aggression

People more readily harm members of outgroups than ingroups, often enjoying the inflicted agony. Yet it remains unclear how these malevolent tendencies towards outgroups relate to sadism. Sadists often harm others, driven by a desire to feel pleasure from their suffering. In attempt to bridge these two lines of research, this work examined relationships between sadism and aggression against ingroup and outgroup members in three studies (total N = 755) that focused on two groups with a history of conflict (i.e., the United Kingdom and the Republic of Ireland). Across all studies, British participants' sadistic tendencies were just as strongly linked to their aggression against ingroup members (i.e., British partners) as to their aggression against outgroup members (i.e., Irish partners). Despite this lack of a preference for greater outgroup aggression, they tended to enjoy outgroup aggression more than ingroup aggression, especially at its extreme levels. These findings extend works linking sadism to aggression into the domain of intergroup relations and bind together research on sadism and intergroup schadenfreude.

Sadism and Personality Disorders

PURPOSE OF REVIEW

Sadistic pleasure-the enjoyment of harm-infliction to others-can have devastating interpersonal and societal consequences. The goal of the current review is to illuminate the nomological net of traits related to sadism. We aim to achieve an understanding of the current empirical status on the link between sadism and personality disorders, psychopathy, the Dark Triad, and basic personality traits in clinical and community-based samples.

RECENT FINDINGS

The field is dominated by self-report studies on the Dark Triad with convenience samples. The link with DSM personality disorders has hardly been empirically studied. Existing evidence shows that sadism is most strongly related to increased psychopathic personality traits. Sadism can originate both from the interpersonal, affective, and behavioural basis of dark personality traits. There are diverging ideas on the differential status between sadism, psychopathy, and other dark traits. Research is needed on the causal impact of the broader range of personality disorders on sadism, in more diverse samples, including behavioural assessments of sadistic pleasure, as well as on the interplay of such personality traits with situational and affective aspects, and victim attitudes.

Everyday Sadism as a Predictor of Rape Myth Acceptance and Perception of Harassment

The #MeToo movement has stressed the need to understand why individuals who witness sexual violence may or may not take action. However, prevention programs usually fail to address the association between personality traits and attitudes, perception, and behavior in the context of sexual violence. To improve prevention programs' effectiveness, it is vital to understand how personality traits might interfere with willingness to engage in bystander intervention. This study aims to explore the relationships between Everyday Sadism, perception of harassment, Rape Myths and gender in a sample of 177 participants recruited online. Analyses revealed significant gender differences, with men endorsing more Rape Myths, perceiving less harassment, and being more sadistic. Gender and everyday sadism emerged as significant predictors of perception of harassment. In the case of Rape Myths, age emerged as an additional predictor. These results have several implications, ranging from expanding our knowledge of the influence of everyday sadism on factors known to modulate bystander behaviors as well as informing and shaping the development of prevention programs.

On the (number of) aversive traits it takes to approximate the common core of aversive personality

The Dark Triad and Dark Tetrad are the constellation of aversive traits that are most commonly assessed to study their common (aversive) and unique (non-aversive) features. Nonetheless, it is unclear whether these particular traits (in combination) indeed closely approximate the common core of all aversive traits. A close approximation of the aversive core, however, is crucial if one is strictly interested in an aversive trait's unique variance. Therefore, the present study aims to specify how many and which aversive traits jointly approximate the aversive core to a satisfactory extent. To this end, the aversive core was first estimated from 16 aversive traits and then correlated to the aversive cores extracted from all 63,002 possible combinations of two to eleven of these traits. Results showed that most combinations of four, or essentially any combination of at least six aversive traits, approximated the aversive core reasonably well, whereas the Dark Triad and Dark Tetrad lead to systematically poorer approximations compared to other combinations of three of four aversive traits.

No mercy for victims: Exploring the link between dark personality traits, aggressive video game behavior, and severe traffic violations

This study investigates the relationship between dark personality traits, aggressive behavior in violent video games, and severe traffic violations among 200 driving offenders from Tehran, Iran, participating in a rehabilitation program. Participants engaged in a computerized shooting decision task, where their tendency to shoot unarmed targets (innocent victims), compared to armed targets (criminals), was used as an indicator of aggressive behavior toward innocent victims. Additionally, they completed self-report measures of narcissism, Machiavellianism, psychopathy, and sadism to evaluate the impact of Dark Tetrad personality traits on their behavior. Bivariate analyses revealed associations between Dark Tetrad personality traits and aggressive behavior in the video game with serious traffic offenses. Multivariate analyses identified Machiavellianism, sadism, and aggressive behavior in video games as significant predictors of severe traffic offenses. The results suggest that dark personality traits and aggressive behavior in video games may aid in better identifying road traffic offenders with the most severe violations. Potential implications for preventing repeated traffic offenses by tailoring rehabilitation programs are discussed.

HEXACO, the Dark Triad, and Chat GPT: Who is willing to commit academic cheating?

The rise in popularity of Chat GPT, an advanced language model that uses deep learning techniques to simulate human-like conversation, has raised concerns about its potential misuse, particularly in academic contexts. The present study (N = 283) explored the relationship between personality traits and the intention to use chatbot-generated texts for academic cheating. Among the HEXACO and Dark Triad traits, Honesty-Humility, Conscientiousness, Openness to Experience (all negative), Machiavellianism, narcissism, and psychopathy (all positive) were significant predictor variables. A multiple regression analysis showed that Honesty-Humility had the most robust association with the intention to use chatbot-generated texts for academic cheating. Further analyses on the facet level revealed that the fairness facet of Honesty-Humility was the most predictive, suggesting that individuals high in Honesty-Humility refrain from using chatbot-generated texts for academic cheating as they prioritize fairness over their own interests. Promoting Honesty-Humility and its fairness facet can be a valuable approach to promoting ethical behavior in academic and other contexts.

Blunted startle reactivity in everyday sadism and psychopathy

Two studies examined the amplitude of the startle response as a function of the Dark Tetrad of personality (narcissism, Machiavellianism, psychopathy, and sadism). We measured electromyographic activity of the orbicularis oculi muscle evoked by a startle stimulus while participants viewed images on a computer screen. Both studies revealed a negative correlation between general startle reactivity (averaged across positive, negative, and neutral images) and sadistic tendencies. In Study 2, all four dark traits were negative correlates of general startle reactivity. Study 2 also examined the personality correlates of aversive startle potentiation (ASP; indexed by greater reactivity while viewing negatively-valenced images than positive or neutral images). ASP correlated negatively with a variety of personality measures of psychopathy and sadism, their facets, and related personality tendencies (callousness, risk-taking, and restricted affect). These findings suggest that ordinary people with high levels of callousness and antagonism display physiological evidence of non-reactivity (i.e., blunted acoustic startle in general), whereas psychopathy and sadism are preferentially associated with reduced ASP.

Conflict experience and resolution underlying obedience to authority

Definitions of obedience require the experience of conflict in response to an authority's demands. Nevertheless, we know little about this conflict and its resolution. Two experiments tested the suitability of the 'object-destruction paradigm' for the study of conflict in obedience. An experimenter instructed participants to shred bugs (among other objects) in a manipulated coffee grinder. In contrast to the demand condition, participants in the control condition were reminded of their free choice. Both received several prods if they defied the experimenter. Results show that participants were more willing to kill bugs in the demand condition. Self-reported negative affect was increased after instructions to destroy bugs relative to other objects (Experiments 1 and 2). In Experiment 2, compliant participants additionally showed an increase in tonic skin conductance and, crucially, self-reported more agency and responsibility after alleged bug-destruction. These findings elucidate the conflict experience and resolution underlying obedience. Implications for prominent explanations (agentic shift, engaged followership) are discussed.

Dark Personality Traits and Online Behaviors: Portuguese Versions of Cyberstalking, Online Harassment, Flaming and Trolling Scales

The main objective of this study is to assess moderation effects of online behaviors between personality traits and addiction to Internet. To this end, four instruments were validated for Portuguese version through confirmatory factor analysis and exploratory factor analysis (Study 1) Multiple regression analysis was applied to examine the personality predictors of specific online behaviors while controlling for gender and age; and moderation effects were assessed (Study 2). Results showed good psychometric properties for the four validated scales. Machiavellianism is positively associated with all the dimensions of this study. Psychopathy is positively associated with total Cyberstalking, Cyberstalking Control, Flaming and Trolling. Narcissism is positively associated with all the dimensions, except Online Harassment and Flaming. Machiavellianism is positively associated with Addiction to Internet through Cyberstalking, Flaming and Trolling. Psychopathy is positively associated with Addiction to Internet through Cyberstalking Control and Flaming. Narcissism is also positively associated with Addiction to Internet through Cyberstalking and Trolling. This study demonstrates that dimensions of the dark triad of personality play an important role in Internet addiction through online behaviors. The results of this study have theoretical and practical implications: on the one hand, they reinforces the findings of other studies showing that dimensions of the dark personality triad play an important role in Internet and social network addition, contributing to the literature; and, on the other hand, on a practical level, they allow to conduct awareness campaigns in communities, schools, and work to understand that one can be exposed to unpleasant situations due to behaviors that some people with personality traits of Machiavellianism, narcissism and/or psychopathy that may cause problems affecting the mental, emotional and psychological health of others.

The Revised Assessment of Sadistic Personality (ASP-8): Evidence for Validity across Four Countries

Subclinical sadism, characterized by infliction of cruelty, aggression, or humiliation on another for subjugation or pleasure, provides important information in the prediction of aversive behaviors that have implications for individuals' and society's well-being worldwide. Given sadism's universal relevance, it is imperative that researchers ensure valid and reliable trait measurement not only among English-speaking individuals, but also cross-nationally among countries in which sadism remains relatively understudied. The objective of the current research was to validate the revised version of the Assessment of Sadistic Personality (ASP-8) (Plouffe et al., 2017) across samples of Russian (n = 1087, M_age = 37.36, SD = 10.36), Greek (n = 1195, M_age = 35.64, SD_age = 13.08), Serbian (n = 443, M_age = 28.10, SD_age = 6.60), and British (n = 511, M_age = 28.50, SD_age = 11.62) adults. Overall, results supported the reliability, dimensionality, and scalar/partial scalar measurement invariance of the ASP-8 across cross-national samples. Convergent and discriminant validity were mostly supported through correlations with general personality traits, the Dark Triad, emotional intelligence, mental toughness, depression, anxiety, stress, satisfaction with life, aggression, and attitudes toward social groups. Based on our findings, we recommend the use of the ASP-8 in future investigations of aversive traits.

Premorbid Personality Traits as Risk Factors for Behavioral Addictions: A Systematic Review of a Vulnerability Hypothesis

The debate on personality structure and behavioral addictions is an outstanding issue. According to some authors, behavioral addictions could arise from a premorbid personality, while for others, it could result from a pathological use of technological tools. The current study aims to investigate whether, in the latest literature, personality traits have been identified as predictors of behavioral addictions. A literature search was conducted under the PRISMA methodology, considering the most relevant studies of the five-factor model from the past 10 years. Overall, most studies on addiction, personality traits, and personality genetics proved that behavioral addiction may be an epiphenomenon of a pre-existing personality structure, and that it more easily occurs in vulnerable subjects with emotional instability, negative affects, and unsatisfactory relationships with themselves, others, and events. Such neurotic personality structure was common to any addictive behavior, and was the main risk factor for both substance and behavioral addictions. Therefore, in clinical and educational contexts, it becomes crucial to primarily focus on the vulnerability factors, at-risk personality traits, and protective and moderating traits such as extroversion, agreeableness, conscientiousness, and openness to experience; meanwhile, treatment of behavioral addictions is frequently focused on overt pathological behaviors.

I'm Offering You My Pain: Priming COVID-19 Salience Increases Everyday Sadism

The COVID-19 pandemic and its link to the emergence of everyday sadism is a matter of public concern worldwide. However, previous studies are nearly silent regarding the causal relationship between the two variables. We address this gap by theorizing that exposure to information about coronavirus can increase sadistic behavior by inducing state boredom. We conducted three complementary controlled experiments, which comprised multiple participants populations (N = 784, student and community samples) and measurement techniques of sadism, to test our theoretical perspective. Based on self-report measures, Study 1 found that Chinese university students who were exposed to a reminder of COVID-19 exhibited a higher level of everyday sadism than participants in the control condition. Study 2 replicated this finding in a more generalized population. Additionally, results revealed that state boredom mediated this effect. Moving beyond subjective self-report data in Studies 1 and 2, Study 3 assessed a different behavioral operationalization of sadistic tendencies, namely, shredding worms. As expected, priming COVID-19 salience has an immediate, statistically significant influence on sadistic behavior in impactful real-world contexts. Overall, these findings suggest that the COVID-19 pandemic not only has grave effects on economy and society, but has implications for the malevolent side of human nature.

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.

Development and validation of Chinese form Short Dark Tetrad (C-SD4)

The Short Dark Tetrad (SD4) was developed as a brief measure of the Dark Tetrad, which comprises narcissism, Machiavellianism, psychopathy, and sadism. Previous research suggests the possibility of cultural differences in these traits in Western and Eastern cultures. We developed and validated the Chinese form of SD4 (C-SD4) cross four studies in a large sample (total N = 3181) to assist in solving problems caused by these differences. In study 1, we adjusted the item pool on the basis of the original form of SD4. In Study 2, we trimmed the scale to generate a 28-item version of C-SD4 and examined correlations with Big-5. In study 3, we examined the internal structure, measurement invariance, and criterion validity of the C-SD4. In study 4 we examined C-SD4 test-retest reliability and compared item content to standard measures. This package of studies suggests that the C-SD4 is a reliable and valid measure of the Dark Tetrad in Chinese participants.

Reactions from the Dark Side: How Does the Dark Tetrad Affect Responses to Daily Abusive Supervision Today and Tomorrow?

Abusive supervision is a widely-studied phenomenon experienced by a multitude of workers across organizations and occupations. It has typically been conceptualized as a chronic phenomenon with negative outcomes. However, preliminary evidence indicates that conceptualizing abusive supervision as constant may not be accurate, and that its outcomes may vary temporally. This study uses a within-person approach to capture the dynamic nature of abusive supervision and subordinate responses more fully. We surveyed 102 full-time employees from the U.S. who responded to 932 daily surveys assessing personality, workplace behaviors, and justice perceptions. Daily abuse led to lower perceptions of justice and increased retaliation on the same day, but not the following days. Rather, employees who engaged in workplace deviance more often reported more abusive supervision, potentially as a justification for their behavior. Further, justice perceptions predicted increased reports of abuse, indicating that this may be a circular relationship instead of a unidirectional one. Finally, narcissism exacerbated the relationships explored. These results can be used to implement interventions directed at both supervisor behavior and subordinate perceptions and behaviors.
