An English-Language adaptation and validation of the Justice Sensitivity Short Scales-8 (JSS-8).

The construct of justice sensitivity has four perspectives that capture individual differences in the strength of reactions to injustice when becoming a victim of injustice (victim sensitivity), when witnessing injustice as an outsider (observer sensitivity), when passively benefitting from an injustice done to others (beneficiary sensitivity), or when committing an injustice (perpetrator sensitivity). Individual differences in these four justice sensitivity perspectives are highly relevant in moral research. With just eight items in total, the Justice Sensitivity Short Scales-8 (JSS-8) are a very efficient way to measure the four perspectives. JSS-8 was initially constructed in German (Ungerechtigkeitssensibilität-Skalen-8, USS-8) and later translated into English. In the present study, we empirically validated this English-language adaptation in a heterogeneous quota sample from the UK. The results show that the psychometric properties (i.e., reliability, validity, standardization) of JSS-8 are good, and that they are comparable with those of the German-language source version. Because of the invariance of loadings, intercepts, and residual variances, researchers can compare manifest scale statistics (i.e., means, variances) of JSS-8 across the UK and Germany. JSS-8 is thus particularly suitable for measuring justice sensitivity in various research areas with constraints on assessment time and questionnaire space.

Personality processes of everyday moral courage.

INTRODUCTION: Moral courage manifests in acts intended to intervene to stop or redress witnessed moral norm violations, despite the risk of negative consequences for the intervener. We investigate moral courage in everyday life and ask what personality processes are involved. Based on an extended process model of moral courage, we derived hypotheses on cognitive and emotional processes that should facilitate or hinder intervention. Further, we identified candidate personality dispositions that should shape these processes and thereby predict who tends to intervene against others' norm violations and who does not. METHODS: Using a quota-based sample of the German population (N = 1108), we conducted a personality assessment, followed by a 7-day experience sampling during which participants reported norm violations witnessed in their daily life as well as their cognitive, emotional, and behavioral reactions. RESULTS: In total, 678 participants reported 1965 norm violations and intervened against 32% of them. Dispositional self-efficacy facilitated intervention by increasing a sense of efficacy when confronted with others' norm violations. Conversely, dispositional moral disengagement hindered intervention by reducing perceived own responsibility. DISCUSSION: Our findings provide novel insights into the situations affording moral courage in everyday life, and the personality processes that uniquely guide this behavior.

"Proof Under Reasonable Doubt": Ambiguity of the Norm Violation as Boundary Condition of Third-Party Punishment.

In six studies, we consistently observed costly third-party punishment (3PP) to decrease under ambiguity of the norm violation. Our research suggests that, under ambiguity, some people experience concerns about punishing unfairly. Those with higher (vs. lower) other-oriented justice sensitivity (Observer JS) reduced 3PP more pronouncedly (in Studies 1-3 and 4b, but not replicated in Studies 4-5). Moreover, those who decided to resolve the ambiguity (hence, removing the risk of punishing unfairly) exceeded the 3PP observed under no ambiguity (Study 4). However, we did not consistently observe these concerns about punishing unfairly to affect 3PP (Studies 4-5). We further considered whether people could use ambiguity as justification for remaining passive-thus, avoiding the costs of 3PP. We did not find conclusive evidence supporting this notion. Taken together, ambiguity entails a situational boundary of 3PP that sheds light on the prevalence of this behavior and, potentially, on its preceding decision-making.

The distinct associations of ingroup attachment and glorification with responses to the coronavirus pandemic: Evidence from a multilevel investigation in 21 countries.

While public health crises such as the coronavirus pandemic transcend national borders, practical efforts to combat them are often instantiated at the national level. Thus, national group identities may play key roles in shaping compliance with and support for preventative measures (e.g., hygiene and lockdowns). Using data from 25,159 participants across representative samples from 21 nations, we investigated how different modalities of ingroup identification (attachment and glorification) are linked with reactions to the coronavirus pandemic (compliance and support for lockdown restrictions). We also examined the extent to which the associations of attachment and glorification with responses to the coronavirus pandemic are mediated through trust in information about the coronavirus pandemic from scientific and government sources. Multilevel models suggested that attachment, but not glorification, was associated with increased trust in science and compliance with federal COVID-19 guidelines. However, while both attachment and glorification were associated with trust in government and support for lockdown restrictions, glorification was more strongly associated with trust in government information than attachment. These results suggest that both attachment and glorification can be useful for promoting public health, although glorification's role, while potentially stronger, is restricted to pathways through trust in government information.

Trust in scientific information mediates associations between conservatism and coronavirus responses in the U.S., but few other nations.

U.S.-based research suggests conservatism is linked with less concern about contracting coronavirus and less preventative behaviors to avoid infection. Here, we investigate whether these tendencies are partly attributable to distrust in scientific information, and evaluate whether they generalize outside the U.S., using public data and recruited representative samples across three studies (Ntotal = 34,710). In Studies 1 and 2, we examine these relationships in the U.S., yielding converging evidence for a sequential indirect effect of conservatism on compliance through scientific (dis)trust and infection concern. In Study 3, we compare these relationships across 19 distinct countries. Although the relationships between trust in scientific information about the coronavirus, concern about coronavirus infection, and compliance are consistent cross-nationally, the relationships between conservatism and trust in scientific information are not. These relationships are strongest in North America. Consequently, the indirect effects observed in Studies 1-2 only replicate in North America (the U.S. and Canada) and in Indonesia. Study 3 also found parallel direct and indirect effects on support for lockdown restrictions. These associations suggest not only that relationships between conservatism and compliance are not universal, but localized to particular countries where conservatism is more strongly related to trust in scientific information about the coronavirus pandemic.

How prosocial is moral courage?

Moral courage, that is, defending moral beliefs despite personal risks, is often seen as a hallmark of prosocial behavior. We argue that prosociality in moral courage is, however, complex. While its prosociality is often evident at a higher societal level, it can be contested in some aspects of morally courageous acts. We review the literature on two such aspects and highlight that differences and conflicts in moral beliefs, as well as the confrontational nature of many morally courageous acts, call into question prosociality. We recommend that future research takes the complexity of prosociality in moral courage into account to obtain a comprehensive and nuanced understanding of the psychological underpinnings of moral courage and its contributions to the functioning of societies.

The functions of anger in moral courage-Insights from a behavioral study.

Moral courage is manifested when bystanders intervene to stop or prevent others' norm transgressions, despite potential costs to themselves. Although theoretical models propose a key role of emotions, in particular anger, in the psychological processes underlying moral courage, to date this role is underexplored. In a behavioral study, we proposed a conceptual differentiation between experienced and expressed anger in response to a witnessed moral transgression. By staging the embezzlement of money from project funds in the lab, we tested whether anger arises in response to a witnessed moral norm transgression and scrutinized its unique contribution to predicting who intervenes and who remains inactive in the context of other theoretically relevant emotions (guilt, fear, and empathy). In addition, we investigated the role of bystanders' anger expression in response to the transgression. Lastly, we tested whether experienced and expressed anger reactions were predicted across time from dispositions. Our paradigm allowed us to obtain observational data of behavioral responses and anger expression and experienced emotion reports in response to a realistic moral norm transgression. Results showed that experienced anger increased after the transgression and uniquely predicted intervention. Experienced anger reaction was predictable across time from dispositional sensitivity to observed injustice. Anger expression was only loosely associated with anger experience and intervention, suggesting it may constitute a display of disapproval in itself. The present findings from a realistic moral transgression situation evidence the important role of anger in the psychological process underlying moral courage.

A Multilab Replication of the Ego Depletion Effect.

There is an active debate regarding whether the ego depletion effect is real. A recent preregistered experiment with the Stroop task as the depleting task and the antisaccade task as the outcome task found a medium-level effect size. In the current research, we conducted a preregistered multilab replication of that experiment. Data from 12 labs across the globe (N = 1,775) revealed a small and significant ego depletion effect, d = 0.10. After excluding participants who might have responded randomly during the outcome task, the effect size increased to d = 0.16. By adding an informative, unbiased data point to the literature, our findings contribute to clarifying the existence, size, and generality of ego depletion.

Causal underpinnings of working memory and Stroop interference control: Testing the effects of anodal and cathodal tDCS over the left DLPFC.

By means of transcranial direct current stimulation applied to the left dorsolateral prefrontal cortex, we investigated the causal role of increased or decreased excitability of this brain region for two facets of executive functions: working memory and Stroop interference control. We tested 1) whether anodal tDCS of the left DLPFC enhances working memory 15 minutes after termination of stimulation and in the absence of direct task practice under stimulation; 2) whether anodal tDCS of the left DLPFC enhances interference control, as evidenced by Stroop performance and Stroop sequence effects; and 3) whether cathodal tDCS leads to compromised executive functioning compared to anodal stimulation. In a between-subject design with 88 healthy psychology students, we compared the impact of anodal and cathodal stimulation against a sham condition, on performance on a Stroop task (during active stimulation) and on an n-back task (completed 15 minutes after active stimulation ended). We found significantly enhanced accuracy in the n-back task after anodal stimulation compared with sham, as well as speeded reactions in the Stroop tasks independent of trial type. By contrast, we found no modulation of Stroop interference effects or Stroop sequence effects. No inhibitory effects of cathodal stimulation were observed. These results support the causal role of the left DLPFC in working memory but lend no support to its involvement in Stroop interference control.

How Victim Sensitivity leads to Uncooperative Behavior via Expectancies of Injustice.

According to the Sensitivity-to-mean-intentions model, dispositional victim sensitivity involves a suspicious mindset that is activated by situational cues and guides subsequent information processing and behavior like a schema. Study 1 tested whether victim-sensitive persons are more prone to form expectancies of injustice in ambiguous situations and whether these expectancies mediate the relationship between victim sensitivity and cooperation behavior in a trust game. Results show an indirect effect of victim sensitivity on cooperation after unfair treatment (vs. control condition), mediated by expectancies of injustice. In Study 2 we directly manipulated the tendency to form expectancies of injustice in ambiguous situations to test for causality. Results confirmed that the readiness to expect unjust outcomes led to lower cooperation, compared to a control condition. These findings provide direct evidence that expectancy tendencies are implicated in elevated victim sensitivity and are of theoretical and practical relevance.

Measuring four perspectives of justice sensitivity with two items each.

People differ systematically in their vulnerability to injustice. We present two-item scales for the efficient measurement of justice sensitivity from 4 perspectives (victim, observer, beneficiary, perpetrator). In Study 1 using a quota-based sample of German adults, a latent state-trait analysis revealed the factorial validity and high reliabilities of the scales. In Study 2 employing a large random sample, we tested for measurement invariance of the items within the context of our short 2-item scales compared to the original 10-item scales. Multigroup confirmatory factor analyses confirmed that the validity of the indicators and the internal structure of the assessed constructs did not change across item contexts. In both studies, correlations with personality dimensions and life satisfaction provide evidence for the validity of our scales. With the presented instrument, future research can extend scientific knowledge regarding the role of individual differences in reactions to injustice for the explanation of well-being and physical health.

Proposal of a Nonlinear Interaction of Person and Situation (NIPS) model.

Marshall and Brown (2006) proposed a Traits as Situational Sensitivities (TASS) Model, which implies a systematic person × situation interaction. We review this model and show that it suffers from several limitations. We extend and modify the model in order to obtain a symmetric pattern of levels and effects for both person and situation factors. Our suggestions result in a general Nonlinear Interaction of Person and Situation (NIPS) Model. The NIPS model bears striking similarities to the Rasch model. Based on the symmetric nature of the NIPS model, we generalize the concept of weak and strong situations to individuals and propose the concepts of weak and strong persons. Finally, we discuss psychological mechanisms that might explain the NIPS pattern and offer ideas for future research.

Interventions against norm violations: dispositional determinants of self-reported and real moral courage.

Moral courage is characterized as a bystander intervention against the norm violations of a perpetrator despite the potential for negative consequences for oneself. We tested a comprehensive set of potential personality determinants of moral courage derived from a model of helping. In Study 1, we used a vignette to assess the self-reported willingness to intervene against a theft. In Study 2, the theft was put into effect, and behavioral reactions were observed. The results of Study 1 showed that moral disengagement, self-efficacy, and social anxiety, which are traits that are known to predict helping, were also related to moral courage intentions. Differently, in Study 2, real moral courage was predicted only by beneficiary sensitivity, a disposition that captures perceptual readiness and affective reactivity to perceived injustice. Our results provide insights into the processes involved in moral courage in a realistic situation and stress the importance of behavioral observations.

Learning to interpret one's own outcome as unjustified amplifies altruistic compensation: a training study.

Interpretational tendencies in ambiguous situations were investigated as causal mechanisms of altruistic compensation. We used a training procedure to induce a tendency to interpret one's own advantages as unjustified. In a subsequent mixed-game, participants had to decide whether to invest their own money to compensate a victim of a norm violation. The amount of one's own resources invested as an altruistic compensation was enhanced after the training procedure compared to controls. These findings suggest that interpretational patterns with regard to injustice determine prosocial behavior. The training procedure offers a potential intervention strategy for enhancing altruistic compensation in bystander situations in which people must invest their own resources to restore justice.

Negative emotional processing induced by spoken scenarios modulates corticospinal excitability.

Emotion is assumed to facilitate the preparation of behavioral responses to environmental stimuli. In the present study, we examined whether emotional processing induced by spoken scenarios of positive and negative content, related to the self or to other people, modulates corticospinal excitability. Motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation (TMS) in 20 volunteers indicated that processing of negative emotional content increased MEP amplitude, regardless of the perspective taken in the scenario. By contrast, positive emotional processing did not reliably alter MEP amplitude. These results provide the first TMS evidence that the auditory processing of emotionally negative information triggers action preparation.
