Bias and error in human judgment

Currently prevalent views of human inference are contrasted with an integrated theory of the epistemic process. The prevailing views are characterized by the following orienting assumptions: (1) There exist reliable criteria of inferential validity based on objectively veridical or optimal modes of information processing. (2) Motivational and cognitive factors bias inferences away from these criteria and thus enhance the likelihood of judgmental error. (3) The layperson's epistemic process is pluralistic; it consists of a diverse repertory of information-processing strategies (heuristics, schemas) selectively invoked under various circumstances. By contrast, the present analysis yields the following conclusions: (1) There exist no secure criteria of validity. (2) Psychological factors that bias inferences away from any currently accepted criteria need not enhance the likelihood of error. (3) The inference process may be considered unitary rather than pluralistic. The various strategies and biases discussed in the literature typically confound universal epistemic process with specific examples (or contents) of such processes. Empirical support for the present analysis is presented, including evidence refuting proposals that specific contents of inference are of universal applicability; evidence suggesting that people do not, because of a reliance on subnormative heuristics, underutilize nonnative statistical information—rather, people seem unlikely to utilize any information if it is nonsalient or (subjectively) irrelevant; and evidence demonstrating that the tendency of beliefs to persevere despite discrediting information can be heightened or lowered by introducting appropriate motivational orientations.     

Making Americans Feel Great Again? Personal Significance Predicts Political Intentions of Losers and Winners of the 2016 U.S. Election

Reactions of losers and winners of political elections have important consequences for the political system during times of power transition. In four studies conducted immediately before and after the 2016 U.S. presidential elections, we investigated how personal significance induced by success or failure of one's candidate is related to hostile versus benevolent intentions toward political adversaries. We found that the less significant supporters of Hillary Clinton and supporters of Donald Trump felt after an imagined (Study 1A) or actual (Study 2) electoral failure the more they were willing to engage in peaceful actions against the elected president and the less they were willing to accept the results of the elections. However, while significance gain due to an imagined or actual electoral success was related to more benevolent intentions among Clinton supporters (Study 1B), it was related to more hostile intentions among Trump supporters (Studies 1B, 2, and 3).     

Need for closure and reactions to innovation

In two studies using Italian (N = 852) and American (N = 94) samples, we hypothesized that high NFC individuals would have lower intentions to use new technological developments, and that this relationship would be mediated by anxiety about the new technology. We found support for this hypothesis in Study 1, but not Study 2. In the second study, we found that the closed‐mindedness subscale of the full NFC scale was related to greater anxiety about new technology, which in turn led to lower intentions to use the new technology. This suggests that the closed‐mindedness facet of NFC may have been responsible for our results. A meta‐analytic synthesis of both studies provided some support for our original mediation hypothesis.     

When opportunity knocks: bottom-up priming of goals by means and its effects on self-regulation

Four studies using general attribute goals or specific task goals revealed that attainment means cognitively activate the goals they are perceived to serve. A range of means replicated this effect including goal-directed activities, specific behavioral strategies, or opportunities, assumed to afford effective goal pursuit. The increased accessibility of a currently pursued goal due to "bottom-up" priming by its attainment means improved task persistence and performance, whereas a similarly increased accessibility of a competing goal impeded task persistence and performance.     

Leaders as Planners and Movers: Supervisors' Regulatory Modes and Subordinates' Performance

In three field studies, we found that leaders high in both locomotion and assessment tendencies (Studies 1 and 2: evaluated by subordinates; Study 3: evaluated by leaders themselves) elicited higher levels of performance from their subordinates (Studies 1 and 3: as assessed by the subordinates themselves; Study 2: as assessed by their supervisors) than leaders low in one or both of these tendencies. The research supports the notion that locomotion and assessment constitute critical regulatory functions whose conjunction is indispensible for successful performance, whether on the level of the individual (Kruglanski et al., 2000) or the group (Mauro et al., 2009).     

The multifinality constraints effect: how goal multiplicity narrows the means set to a focal end

In the presence of several objectives, goal conflict may be avoided via multifinal means, which advance all of the active goals at once. Because such means observe multiple constraints, they are fewer in number than the unconstrained means to a single goal. Five experimental studies investigated the process of choosing or generating such means for multiple goals. We found that the simultaneous activation of multiple goals restricted the set of acceptable means to ones that benefitted (or at least, did not harm) the entire set of active goals. Two moderators of this phenomenon were identified: (a) the feasibility of identifying multifinal means, which was dependent on the relations between the different active goals, and (b) the enhanced importance of the focal goal, which resulted in the inhibition of its alternatives and the consequent relaxation of multifinality constraints.     

Terrorism Between "Syndrome" and "Tool"

ABSTRACT— Two psychological views of terrorism are described, approaching it as a "syndrome" and as a "tool" respectively. Research thus far found little support for the syndrome view. The heterogeneity of terrorism's users is consistent with the tool view, affording an analysis of terrorism in terms of goal–means psychology.     

Does inconsistency always lead to negative affect? The influence of need for closure on affective reactions to cognitive inconsistency

We present an experiment showing that need for closure (NFC)—defined as the epistemic desire for certainty—can moderate individuals' affective reactions to cognitive inconsistency. Informed by Kruglanski and colleagues' new theory, that cognitive inconsistency elicits negative affect particularly under certain circumstances, we find that NFC (i.e. the desire for certain, stable and unambiguous knowledge) influences the strength of consistency effects and resulting negative affect. More specifically, we find that individuals who are high on NFC experience more negative affect upon encountering an inconsistent (vs. consistent) cognition. However, when individuals are low on NFC, inconsistency is irrelevant, and their affect depends on whether the ultimate outcome of the cognition is positive or negative. We discuss the theoretical and practical implications of this research.     

Disparate roads to certainty processing strategy choices under need for closure

This paper describes a programme of research addressing an intriguing inconsistency in research findings about cognitive processes under a high need for cognitive closure (NFC). While early studies demonstrated that individuals who seek closure opt for closed-minded cognitive strategies, a growing body of research has identified a number of circumstances in which individuals who are high in NFC engage in effortful, open-minded information processing to an even greater extent than their low NFC counterparts. This has posed the challenge of delineating the circumstances under which people motivated to reduce uncertainty (i.e., attain closure) engage in effortful and open-minded cognition from those situations in which they rely on simplistic, low-effort strategies. This also calls for theoretical advancement in NFC theory. We discuss our proposed solution to this puzzle and the implications of this model for real-world social phenomena.     

Deradicalizing Detained Terrorists

Deradicalization of terrorists constitutes a critical component of the global “war on terror.” Unfortunately, little is known about deradicalization programs, and evidence for their effectiveness is derived solely from expert impressions and potentially flawed recidivism rates. We present the first empirical assessment of one such program: the Sri Lankan rehabilitation program for former members of the Liberation Tigers of Tamil Eelam (a terrorist organization that operated in Sri Lanka until their defeat in 2009). We offer evidence that deradicalization efforts that provided beneficiaries with sustained mechanisms for earning personal significance significantly reduced extremism after 1 year (Study 1). We also found that upon release, beneficiaries expressed lower levels of extremism than their counterparts in the community (Study 2). These findings highlight the critical role of personal significance in deradicalization efforts, offer insights into the workings of deradicalization, and suggest practical methods for improving deradicalization programs worldwide.
