Putting situational affordances in an intervention context: How the interaction between personality and intervention situations can help us explain differential intervention responses.

We propose a framework in which interventions are described as situations affording the expression of certain personality traits to provide a systematic understanding of differential intervention response by personality traits. The goal of the present paper is twofold: 1) elaborate on the proposed framework, and 2) provide an initial test of this framework. We empirically tested this framework using data from a Randomized Controlled Trial (N = 176) that examined a smartphone-based intervention aimed at increasing future-oriented thinking and behavior, and assessed HEXACO personality traits.

When does criminal victimization undermine generalized trust? A weighted panel analysis of the effects of crime type, frequency, and variety.

Scholars from various fields have suggested that criminal victimization can shatter generalized trust. Whereas small average effects in longitudinal studies provide only weak support for this claim, victimization effects may be stronger for specific crime types and multiple victimization. To test this assumption, we estimated various victimization effects by combining Energy weighting with lagged dependent variable models, using data from two-wave panel surveys conducted in 2014/2015 (cohort 1; N = 3401) and 2020/2021 (cohort 2; N = 2932) in two German cities.

Effectiveness of ex ante honesty oaths in reducing dishonesty depends on content.

Dishonest behaviours such as tax evasion impose significant societal costs. Ex ante honesty oaths-commitments to honesty before action-have been proposed as interventions to counteract dishonest behaviour, but the heterogeneity in findings across operationalizations calls their effectiveness into question. We tested 21 honesty oaths (including a baseline oath)-proposed, evaluated and selected by 44 expert researchers-and a no-oath condition in a megastudy involving 21,506 UK and US participants from Prolific.

The core tendencies underlying prosocial behavior: Testing a person-situation framework.

Objective And Background: According to a recently proposed theoretical framework, different personality traits should explain pro-social behavior in different situations. We empirically tested the key proposition of this framework that each of four "core tendencies" (i.e.

Personality, self-knowledge, and meat reduction intentions.

Objective: Meat consumption has a host of serious negative consequences for nonhuman animals, underprivileged humans, and the natural environment. Several interventions have been developed to encourage meat reduction but to relatively limited effect. There is also a range of established predictors of meat consumption, but much less is known about the factors that predict intentions to reduce meat consumption.

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.

Testing the equivalence of the aversive core of personality and a blend of agreeableness(-related) items.

Objective: There is an ongoing debate in personality research whether the common core of aversive ("dark") traits can be approximated by or even considered equivalent to one of the constructs that have been labeled "Agreeableness". In particular, it has been suggested that the low pole of (what we term) AG+, a broad blend of Big Five Agreeableness and the HEXACO factors Honesty-Humility, Agreeableness, and Altruism, is essentially equivalent to the Dark Factor of Personality (D). Based on theoretical differences, we herein test empirically whether D and AG+ are isomorphic.

The Dispositional Essence of Proactive Social Preferences: The Dark Core of Personality vis-à-vis 58 Traits.

Individuals differ in how they weigh their own utility versus others'. This tendency codefines the dark factor of personality (D), which is conceptualized as the underlying disposition from which all socially and ethically aversive (dark) traits arise as specific, flavored manifestations. We scrutinize this unique theoretical notion by testing, for a broad set of 58 different traits and related constructs, whether any predict how individuals weigh their own versus others' utility in proactive allocation decisions (i.

Making rights from wrongs: The crucial role of beliefs and justifications for the expression of aversive personality.

Whereas research focusing on stable dispositions has long attributed ethically and socially aversive behavior to an array of aversive (or "dark") traits, other approaches from social-cognitive psychology and behavioral economics have emphasized the crucial role of social norms and situational justifications that allow individuals to uphold a positive self-image despite their harmful actions. We bridge these research traditions by focusing on the common core of aversive traits (the dark factor of personality [D]) and its defining aspect of involving diverse beliefs that serve to construct justifications. In particular, we theoretically specify the processes by which D is expressed in aversive behavior-namely, through diverse beliefs and the justifications they serve.

Trait-specificity versus global positivity: A critical test of alternative sources of assumed similarity in personality judgments.

For decades, a recurring question in person perception research has been whether people's perceptions of others' personality traits are related to how they see themselves on these traits. Indeed, evidence for such "assumed similarity" effects has been found repeatedly, at least for certain characteristics. However, recent research suggests that these findings may be an artifact of individual differences in how positively or negatively perceivers see others in general, irrespective of trait-specific content.

Beyond (low) Agreeableness: Toward a more comprehensive understanding of antagonistic psychopathology.

In clinical psychopathology research, up to seven traits have been suggested as instances of antagonistic psychopathology. Those antagonistic traits, in turn, are commonly viewed as reflections of low Agreeableness as per the Big Five (BF-AG). However, specific theoretical differences between antagonistic traits suggest that other broad, basic dimensions beyond BF-AG ought to provide further points of correspondence.

Test-retest reliability of the HEXACO-100-And the value of multiple measurements for assessing reliability.

Despite the widespread use of the HEXACO model as a descriptive taxonomy of personality traits, there remains limited information on the test-retest reliability of its commonly-used inventories. Studies typically report internal consistency estimates, such as alpha or omega, but there are good reasons to believe that these do not accurately assess reliability. We report 13-day test-retest correlations of the 100- and 60-item English HEXACO Personality Inventory-Revised (HEXACO-100 and HEXACO-60) domains, facets, and items.

Prosocial behavior and altruism: A review of concepts and definitions.

The field of prosociality is flourishing, yet researchers disagree about how to define prosocial behavior and often neglect defining it altogether. In this review, we provide an overview about the breadth of definitions of prosocial behavior and the related concept of altruism. Common to almost all definitions is an emphasis on the promotion of welfare in agents other than the actor.

Gossip and reputation in everyday life.

Gossip-a sender communicating to a receiver about an absent third party-is hypothesized to impact reputation formation, partner selection, and cooperation. Laboratory experiments have found that people gossip about others' cooperativeness and that they use gossip to condition their cooperation. Here, we move beyond the laboratory and test several predictions from theories of indirect reciprocity and reputation-based partner selection about the content of everyday gossip and how people use it to update the reputation of others in their social network.

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.

The dispositional basis of human prosociality.

Individual differences in prosocial behavior have been consistently observed in a variety of contexts. Here, we summarize and critically discuss recent developments in two research agendas on the dispositional basis of human prosociality: a personality approach, proposing a variety of trait concepts and corresponding measures to predict prosocial behavior in different situations; and a behavioral consistency approach, testing for consistency in prosocial behaviors and its underlying latent disposition(s) across situations. Drawing on different properties of situations (so-called situational affordances), we outline a theoretical framework that can help integrate these so far hardly connected research agendas.

Are social desirability scales desirable? A meta-analytic test of the validity of social desirability scales in the context of prosocial behavior.

Social desirability (SD) scales have been used for decades in psychology and beyond. These scales are sought to measure individuals' tendencies to present themselves overly positive in self-reports, thus allowing to control for SD biases. However, research increasingly questions the validity of SD scales, proposing that SD scales measure substantive trait characteristics rather than response bias.

Stockpiling during the COVID-19 pandemic as a real-life social dilemma: A person-situation perspective.

Prior research using economic games has shown that personality drives cooperation in social dilemmas. In this study, we tested the generalizability of these findings in a real-life social dilemma during the COVID-19 pandemic, namely stockpiling in the presence of low versus high resource scarcity. Honesty-Humility was negatively related to stockpiling intentions and justifiability of stockpiling.

Who wants to change and how? On the trait-specificity of personality change goals.

The study of volitional personality change has received increasing attention in recent years, suggesting that individuals want to change for the better particularly on those socially desirable characteristics that they lack. However, individuals do not want to change for the better on all (even socially desirable) traits alike. In a meta-analytic summary of evidence on the Big Five, we demonstrate that individuals' trait levels are only negatively related to their change goals for Neuroticism, Extraversion, and Conscientiousness, but not for Agreeableness and Openness to Experience.

Labelling affects agreement with political statements of right-wing populist parties.

In light of the recent rise of right-wing populist parties across Europe, it is an intriguing question under which conditions people agree with right-wing political statements. The present study investigates whether mere labelling of political statements as endorsed by a right-wing populist party influences people's agreement with such statements. In the study (pre-registered; N = 221 German voters), it is shown than that supporters of the right-wing populist party indicated higher agreement with the statements when they were labelled as being endorsed by the party (vs.

A psychometric evaluation of the Standardized Assessment of Severity of Personality Disorder (SASPD) in nonclinical and clinical German samples.

The Standardized Assessment of Severity of Personality Disorder (SASPD) is a 9-item self-report screening instrument and was developed to assess personality disorder (PD) severity according to the initial proposal of ICD-11. Our aim was to investigate the psychometric properties of the German version of the SASPD in nonclinical and clinical samples. A total of 1,991 participants ( = 888 from nonclinical and = 1,103 from clinical samples) provided ratings on the SASPD as well as other measures of psychopathology and personality.

The dark core of personality and socially aversive psychopathology.

Objective: Although dark traits as studied in mainstream personality research and socially aversive psychopathology as studied in abnormal psychology intend to account for the same classes of behavior, their degree of conceptual and, consequently, empirical correspondence has remained limited at best. We aim to overcome this divide by demonstrating clear convergence between the common core of all dark traits (the Dark Factor of Personality, D) and the four prominent instances of socially aversive psychopathology: narcissistic, antisocial, paranoid, and borderline tendencies.

Method: In a large-scale, eight-month longitudinal study we assessed D, basic personality (the six HEXACO dimensions), and narcissistic, antisocial, paranoid, and borderline tendencies at time 1 (N = 2,329) and the latter aversive tendencies again at time 2 (N = 668) using different inventories.
