Temporal comparisons shape system justification processes
A central aspect of political conservatism is the notion that the system is fair. Political conservatives tend to defend the system more than do liberals. Here we test whether the link between political orientation and this system justification tendency depends on the comparisons people make across time. Across five studies, we found that the typically observed link between conservative (vs. liberal) political orientation and system justification…
Psychologie der Rechtsradikalisierung
Wie radikalisieren sich Menschen und warum ist die Empfänglichkeit für rechte Radikalisierungsdynamiken aktuell besonders hoch? Dieses Buch bietet Einblicke in die psychologische Forschung zu diesen Fragen. Wissenschaftlerinnen und Wissenschaftler stellen in prägnanter und verständlicher Weise Erkenntnisse und Forschungslücken dar. Die Beiträge diskutieren insbesondere die motivationale Bedeutung von Verlust- und Benachteiligungserfahrungen, das …
Relativity in Social Cognition
A key challenge for social psychology is to identify unifying principles that account for the complex dynamics of social behaviour. We propose psychological relativity and its core mechanism of comparison as one such unifying principle. To support our proposal, we review recent evidence investigating basic processes underlying and novel applications of social comparisons. Specifically, we clarify determinants of assimilation and contrast, evaluat…
Psychological power increases the desire for social distance but reduces the sense of social distance
How vertical elevation affects self-other integration as measured by the joint Simon effect
Earlier findings suggest that positions of power decrease self-other integration and increase psychological distance to others. Until now, however, evidence for this relation rests exclusively on subjective measures. The current research instead employed a vertical joint Simon task to measure self-other integration. This task assesses the extent to which people represent their own actions in reference to their co-actor's, also referred to as the …
Self-control failure increases a strategic preference for submission as means to avoid future failure
Moral Character Impression Formation Depends on the Valence Homogeneity of the Context
People quickly form impressions about moral character; for example, if people learn that someone cheated, they form a negative impression about that person’s character and expect that person to cheat in the future. Four studies show that the formation of such moral character impressions depends on the degree of valence homogeneity in the target’s context. We argue that this is the case because the degree of homogeneity in the context (the evaluat…
Past-focused temporal communication overcomes conservatives’ resistance to liberal political ideas
Nine studies and a meta-analysis test the role of past-focused temporal communication in reducing conservatives' disagreement with liberal political ideas. We propose that conservatives are more prone to warm, affectionate, and nostalgic feelings for past society. Therefore, they are more likely to support political ideas-including those expressing liberal values-that can be linked to a desirable past state (past focus), rather than a desirable f…
Stressing the Advantages of Female Leadership Can Place Women at a Disadvantage
Women are still underrepresented in management and men hold the majority of higher positions. Nonetheless, one often-heard claim in popular media is that female people-centered leadership skills (empathy, communication, etc.) are a better match for the business world - especially in the future. Furthermore, a related idea is that women may use this advantage to take over men's dominant position in leadership. Four studies show that such claims pa…
Gender Stereotype-Inconsistent Acts Are Seen as More Acceptable Than Stereotype-Consistent Acts, if They Are Clever
Four studies show that gender stereotype-inconsistent behavior is seen as more acceptable than gender stereotype-consistent behavior, if it is clever. Four studies found consistently that participants rated the behavior of a man who relied on attractiveness or passiveness (stereotypically female) to be more acceptable than similar behavior by a woman. The behavior of a woman who relied on dominance or aggressiveness (stereotypically male) was som…

Not all rejections are alike; competence and warmth as a fundamental distinction in social rejection
Writing autobiographical narratives increases political conservatism
Political Diversity in Social and Personality Psychology
A lack of political diversity in psychology is said to lead to a number of pernicious outcomes, including biased research and active discrimination against conservatives. We surveyed a large number (combined N = 800) of social and personality psychologists and discovered several interesting facts. First, although only 6% described themselves as conservative “overall,” there was more diversity of political opinion on economic issues and foreign po…
Power Increases Social Distance
Five experiments investigated the effect of power on social distance. Although increased social distance has been suggested to be an underlying mechanism for a number of the effects of power, there is little empirical evidence directly supporting this claim. Our first three experiments found that power increases social distance toward others. In addition, these studies demonstrated that this effect is (a) mediated by self-sufficiency and (b) mode…
The powerful disregard social comparison information
Abstraction increases hypocrisy
Power Increases Hypocrisy
In five studies, we explored whether power increases moral hypocrisy (i.e., imposing strict moral standards on other people but practicing less strict moral behavior oneself). In Experiment 1, compared with the powerless, the powerful condemned other people's cheating more, but also cheated more themselves. In Experiments 2 through 4, the powerful were more strict in judging other people's moral transgressions than in judging their own transgress…
Power and behavioral approach orientation in existing power relations and the mediating effect of income
A large number of authors have observed that the experience of power increases behavioral approach tendencies. There are however some important unresolved problems. Predominantly, the literature relies on lab manipulations, priming, and student populations. This has resulted in low face validity. Also, it is unclear what process underlies this effect. A large‐scale survey ( N = 3082) reliably measures power among real low‐ and high‐power employee…
Iron ladies, men of steel
Women remain a minority in politics. In nearly all countries, including parliamentary democracies, women are still underrepresented in national parliament and other representative institutions. Research has argued that there is a bias against women in elections. Here we study the process behind this phenomenon by investigating the effect of a candidate's gender and gender prototypicality on judgment of the suitability of this candidate in electio…
Illegitimacy Moderates the Effects of Power on Approach
A wealth of research has found that power leads to behavioral approach and action. Four experiments demonstrate that this link between power and approach is broken when the power relationship is illegitimate. When power was primed to be legitimate or when power positions were assigned legitimately, the powerful demonstrated more approach than the powerless. However, when power was experienced as illegitimate, the powerless displayed as much appro…
Looking through the eyes of the powerful
Across four experiments, we test the idea that power decreases metastereotyping, and that this effect is mediated by reduced perspective taking. Metastereotypes refer to the beliefs that members of group A share about the stereotypes that members of specific outgroup B typically have about ingroup A. We propose that the dominant psychological orientation of the powerless is aimed at seeing how others see them. In an intergroup situation they are …
