‘They will not control us’: Ingroup positivity and belief in intergroup conspiracies

This research examined the role of different forms of positive regard for the ingroup in predicting beliefs in intergroup conspiracies. Collective narcissism reflects a belief in ingroup greatness contingent on others’ recognition. We hypothesized that collective narcissism should be especially likely to foster outgroup conspiracy beliefs. Non‐narcissistic ingroup positivity, on the other hand, should predict a weaker tendency to believe in conspiracy theories. In Study 1, the endorsement of conspiratorial explanations of outgroup actions was positively predicted by collective narcissism but negatively by non‐narcissistic ingroup positivity. Study 2 showed that the opposite effects of collective narcissism and non‐narcissistic ingroup positivity on conspiracy beliefs were mediated via differential perceptions of threat. Study 3 manipulated whether conspiracy theories implicated ingroup or outgroup members. Collective narcissism predicted belief in outgroup conspiracies but not in ingroup conspiracies, while non‐narcissistic ingroup positivity predicted lower conspiracy beliefs, regardless of them being ascribed to the ingroup or the outgroup.     

Toward a Non-memory Misinformation Effect: Accessing the Original Source Does Not Prevent Yielding to Misinformation

The misinformation effect is regarded by many to be fully memory-related. The paper presents results demonstrating that it may occur without memory distortions or source monitoring errors. Three experiments were conducted, in which the participants were allowed to access the original and post-event source while answering. All experiments used a discrepancy detection test in order to see whether participants aware of discrepancies and having access to the original source, still provide answers consistent with misinformation. In Experiments 2 and 3, the participants’ actions in the modified procedure were recorded, ensuring that subjects actively access the original source. A misinformation effect was obtained in all experiments. Moreover, awareness of discrepancies did not fully protect against the misinformation effect. Results demonstrate that existing memory-related explanations of the misinformation effect, including source misattribution, may not be enough to fully understand it.     

Explanations in cognitive science: unification versus pluralism

The debate between the defenders of explanatory unification and explanatory pluralism has been ongoing from the beginning of cognitive science and is one of the central themes of its philosophy. Does cognitive science need a grand unifying theory? Should explanatory pluralism be embraced instead? Or maybe local integrative efforts are needed? What are the advantages of explanatory unification as compared to the benefits of explanatory pluralism? These questions, among others, are addressed in this Synthese’s special issue. In the introductory paper, we discuss the background of the questions, distinguishing integrative theorizing from building unified theories. On the one hand, integrative efforts involve collaboration between various disciplines, fields, approaches, or theories. These efforts could even be quite temporary, without establishing any long-term institutionalized fields or disciplines, but could also contribute to developing new interfield theories. On the other hand, unification can rely on developing complete theories of mechanisms and representations underlying all cognition, as Newell’s “unified theories of cognition”, or may appeal to grand principles, as predictive coding. Here, we also show that unification in contemporary cognitive science goes beyond reductive unity, and may involve various forms of joint efforts and division of explanatory labor. This conclusion is one of the themes present in the content of contributions constituting the special issue.
