On the relationship between indirect measures of Black versus White racial attitudes and discriminatory outcomes
The idea that racial prejudice contributes to discrimination not only deliberately but also in a more automatic fashion has been one of the most prominent topics in social psychological research in the past 30 years. Much of the evidence for theories of automatic prejudice stems from the use of indirect measures of implicit attitudes, yet meta-analyses give differing estimates regarding the predictive validity of such measures. The present advers…
Polarized Attitudes and Anti-Democratic Orientation
Influential perspectives on polarization in the United States imply that partisans will be more willing to degrade democracy when they are ideologically aligned with their own party and negatively oriented toward the opposing party. But psychological accounts of political ideology suggest that conservatives will be especially anti-democratic regardless of partisanship. Integrating insights from these areas, we argue that there are reasons to expe…
Durably reducing conspiracy beliefs through dialogues with AI
Conspiracy theory beliefs are notoriously persistent. Influential hypotheses propose that they fulfill important psychological needs, thus resisting counterevidence. Yet previous failures in correcting conspiracy beliefs may be due to counterevidence being insufficiently compelling and tailored. To evaluate this possibility, we leveraged developments in generative artificial intelligence and engaged 2190 conspiracy believers in personalized evide…
The psychological causes and societal consequences of authoritarianism
On the Association between Grants and Scholarly Achievement among the World’s Most Eminent Psychologists
Development and Initial Validation of Two Brief Measures of Left-Wing Authoritarianism
Although authoritarianism has predominantly been studied among political conservatives, authoritarian individuals exist on both "poles" of the political spectrum. A 39-item multidimensional measure of left-wing authoritarianism, the Left-wing Authoritarianism Index, was recently developed to extend the study of authoritarianism to members of the far-left. The present study coupled a fully automated machine learning approach (i.e., a genetic algor…
Absolute Certainty and Political Ideology
The present investigation examined curvilinear relations between political ideology, on the one hand, and absolute certainty and dogmatism, on the other, across six online samples ( N = 2,889). Ideological extremists were more likely than others to be absolutely certain: About one in three extremists reported being absolutely (i.e., 100%) certain of the correctness of their political beliefs, whereas about one in 15 non-extremists reported being …
The conspiratorial mind
A tidal wave of research has tried to uncover the motivational and personological correlates of conspiratorial ideation, often studying these two classes of correlates in parallel. Here, we synthesize this vast and piecemeal literature through a multilevel meta-analytic review that spanned 170 studies, 257 samples, 52 variables, 1,429 effect sizes, and 158,473 participants. Overall, we found that the strongest correlates of conspiratorial ideatio…
Revisiting the rigidity-of-the-right hypothesis
conservatives are essentially rigid to when and why they might or might not be, will help provide a more realistic account of the psychological underpinnings of political ideology. (PsycInfo Database Record (c) 2023 APA, all rights reserved)
Professed Democracy Support and Openness to Politically Congenial Authoritarian Actions Within the American Public
Elites degrade democracy in part because of incentives that arise from public opinion. We report pre-registered and exploratory tests of which Americans are most likely to support democracy-degrading action, focusing on three distinct democracy attitudes assessed in a large demographically representative sample 5 weeks before the 2020 election. Professed opposition to democracy was relatively rare and most common among citizens who felt disengage…
Stepping Outside the Echo Chamber
In recent years, an upsurge of polarization has been a salient feature of political discourse in America. A small but growing body of research has examined the potential relevance of intellectual humility (IH) to political polarization. In the present investigation, we extend this work to political myside bias, testing the hypothesis that IH is associated with less bias in two community samples ( N 1 = 498; N 2 = 477). In line with our expectatio…
Spanish Adaptation of the Left-Wing Authoritarianism Index
Notwithstanding long-simmering controversies around the construct, several studies have gathered consistent evidence of authoritarian attitudes among left-wing voters and activists. Recently, Costello et al. (Clarifying the structure and nature of left-wing authoritarianism. Journal of Personality and Social Psychology, 2021) validated, in the English-speaking context, a three-factor scale to measure left-wing authoritarianism, as well as two sho…
Feeling Powerful” versus “Desiring Power”
Clarifying the structure and nature of left-wing authoritarianism
Authoritarianism has been the subject of scientific inquiry for nearly a century, yet the vast majority of authoritarianism research has focused on right-wing authoritarianism. In the present studies, we investigate the nature, structure, and nomological network of left-wing authoritarianism (LWA), a construct famously known as "the Loch Ness Monster" of political psychology. We iteratively construct a measure and data-driven conceptualization of…
The curious case of left‐wing authoritarianism
Left-wing authoritarianism (LWA) has a controversial history in psychology. Some researchers have expressed skepticism about the existence of LWA, whereas others have argued that LWA is a valid construct. In the present article, we offer a framework to reconcile these two perspectives by proposing that ideologically based authoritarian norms are sometimes in conflict with the processes that create authoritarian individuals. In Western political c…
Social and Economic Political Ideology Consistently Operate as Mutual Suppressors
Right–left political views can be decomposed into distinct economic and social dimensions that bear differing relations with external criteria. In three community samples (total N = 1,487), we identified replicable suppressor situations in which statistically controlling for either social or economic political ideology increased the other ideology dimension’s relations with variables reflecting cognitive rigidity, authoritarianism, dangerous worl…
Looking under the tinfoil hat
OBJECTIVE: We sought to replicate and extend provisional research on the personological correlates of conspiracy beliefs by examining their associations with abnormal- and normal-range personality domain-level traits and, for the first time, lower-order personality facets; we also examined internalizing symptoms. METHOD: = 1,927), and examined the cross-sectional relations between self-reported conspiratorial ideation and measures of (a) the six-…
