A Systematic Scoping Review of the Choice Architecture Movement: Toward Understanding When and Why Nudges Work

In this paper, we provide a domain‐general scoping review of the nudge movement by reviewing 422 choice architecture interventions in 156 empirical studies. We report the distribution of the studies across countries, years, domains, subdomains of applicability, intervention types, and the moderators associated with each intervention category to review the current state of the nudge movement. Furthermore, we highlight certain characteristics of the studies and experimental and reporting practices that can hinder the accumulation of evidence in the field. Specifically, we found that 74% of the studies were mainly motivated to assess the effectiveness of the interventions in one specific setting, while only 24% of the studies focused on the exploration of moderators or underlying processes. We also observed that only 7% of the studies applied power analysis, 2% used guidelines aiming to improve the quality of reporting, no study in our database was preregistered, and the used intervention nomenclatures were non‐exhaustive and often have overlapping categories. Building on our current observations and proposed solutions from other fields, we provide directly applicable recommendations for future research to support the evidence accumulation on why and when nudges work.

Are There Enough Injective Sets?

The axiom of choice ensures precisely that, in ZFC, every set is projective: that is, a projective object in the category of sets. In constructive ZF (CZF) the existence of enough projective sets has been discussed as an additional axiom taken from the interpretation of CZF in Martin-Löf’s intuitionistic type theory. On the other hand, every non-empty set is injective in classical ZF, which argument fails to work in CZF. The aim of this paper is to shed some light on the problem whether there are (enough) injective sets in CZF. We show that no two element set is injective unless the law of excluded middle is admitted for negated formulas, and that the axiom of power set is required for proving that “there are strongly enough injective sets”. The latter notion is abstracted from the singleton embedding into the power set, which ensures enough injectives both in every topos and in IZF. We further show that it is consistent with CZF to assume that the only injective sets are the singletons. In particular, assuming the consistency of CZF one cannot prove in CZF that there are enough injective sets. As a complement we revisit the duality between injective and projective sets from the point of view of intuitionistic type theory.     

Studying the role of cognitive control in reasoning: evidence for the congruency sequence effect in the ratio-bias task

In this study, we investigated whether control of the conflict between incongruent heuristic and analytical answer options in a reasoning task is modulated by the presence of conflict on previous trials. In two experiments, we found that the incongruency of the previous trial has a significant effect on the control exhibited on the current trial. Our data also showed that this adaptation effect is modulated by the incongruency of the previous series of trials. These results demonstrate the same control adaptation effects for a reasoning task as observed for standard response interference tasks. Coinciding control effects in the two research areas suggest that cognitive control might be an important mechanism underlying performance on reasoning tasks. Based on these results we argue that the study of cognitive control in reasoning could potentially facilitate the refinement of empirical predictions and provide a new tool to explore the exertion of top-down control in human thinking.     

Economic inequality is linked to biased self-perception

People's self-perception biases often lead them to see themselves as better than the average person (a phenomenon known as self-enhancement). This bias varies across cultures, and variations are typically explained using cultural variables, such as individualism versus collectivism. We propose that socioeconomic differences among societies--specifically, relative levels of economic inequality--play an important but unrecognized role in how people evaluate themselves. Evidence for self-enhancement was found in 15 diverse nations, but the magnitude of the bias varied. Greater self-enhancement was found in societies with more income inequality, and income inequality predicted cross-cultural differences in self-enhancement better than did individualism/collectivism. These results indicate that macrosocial differences in the distribution of economic goods are linked to microsocial processes of perceiving the self.     

From Fame to Glory. The Case of Prince Friedrich of Homburg

The paper examines the value of glory and offers a conception of it, which is developed by criticising other accounts and by arguing that the Homeric and the Biblical traditions have a remarkably similar, converging view on glory. A more detailed analysis of Heinrich von Kleist's The Prince Friedrich of Homburg serves to deepen this view and outline an account of glory that rests on the following claims: it is different from, although not entirely opposite to, fame; it is related to victory, to abundant, everlasting life, and to a certain type of passivity and dialogical contemplation.     

The Effect of Transparency on Framing Effects in Within‐Subject Designs

A long‐lasting assumption about the framing effect is that if the participants discover the purpose of the experiment in a within‐subject design, then this test transparency would trigger them to override their initial answer and make coherent choices. For this reason, researchers try to mask the connection between the two parts of the test by inserting filling questions or a time delay between the two parts of the test. In this research, we explored the extent to which these customarily used masking solutions are effective in increasing test sensitivity for the framing effect. In three experiments, we assessed the effect of masking on the tests of the attribute framing and the risky‐choice framing effects. Contradicting the general belief, our results indicate that these effects are already measurable without any masking or delay and we found no convincing evidence that the attempts to decrease task transparency provide worthwhile benefits for general tests of the effect. Beyond their practical relevance, the results question whether the test is a good measure of coherence rationality and better suit those accounts that suggest that the two parts of the framing tasks cannot be regarded as identical.

Binary Refinement Implies Discrete Exponentiation

Working in the weakening of constructive Zermelo-Fraenkel set theory in which the subset collection scheme is omitted, we show that the binary re.nement principle implies all the instances of the exponentiation axiom in which the basis is a discrete set. In particular binary re.nement implies that the class of detachable subsets of a set form a set. Binary re.nement was originally extracted from the fullness axiom, an equivalent of subset collection, as a principle that was su.cient to prove that the Dedekind reals form a set. Here we show that the Cauchy reals also form a set. More generally, binary refinement ensures that one remains in the realm of sets when one starts from discrete sets and one applies the operations of exponentiation and binary product a finite number of times.

Confirmation of the three-factor model of the Assessing Emotions Scale (AES): Verification of the theoretical starting point

Several measures have been developed for the quantification of emotional intelligence. One widely applied method is the Assessing Emotions Scale, whose factor structure has attracted much scientific attention. The objective of the present study was to identify which of the previously suggested models are the most appropriate. By applying confirmatory factor analysis, we have tested the original one-, three-, four-, and six-factor solutions. Results confirmed the three-factor structure to be the most suitable solution. We suggest that the factors in this structure are better described by the labels “appraisal of emotions,” “optimism and regulation of emotions,” and “intrapersonal and interpersonal utilization of emotions.” Supplemental materials for this article may be downloaded from http://brm.psychonomic-journals.org/content/supplemental.     

Moral Philosophy and the Ontology of Relations

The essay undertakes to explore the possibilities of mutually fruitful dialogue between moral philosophy and ontology, in particular, the ontology of relations. The latter copes with the question of how relations relate, whereas moral philosophy often ignores the ontological implications of such crucial relations as love and interpersonality. The paper proceeds as follows. First, the ontology of relations is discussed. Second, various examples are analysed. From this, a conception of relation instantiation emerges, according to which to determine which relation actually obtains, one has to take into account (a) the context, (b) the specific content or meaning of the relation, and (c) some action or decision or mode of existence of the relata. This conception suggests that relation instantiation cannot be explained by a single formula. By the help of this conception, Hume's thesis of the identity of killing relations between human and nonhuman beings is questioned. Then, the relation of love is analysed. It is shown that love as a moral relation is perfectly explicable in terms of ontology. Moreover, its essence is best captured by the interrelation of the particulars, the relation of love as a universal, and by the relating action of the particulars. Finally, the alleged relation of universal fraternity (interpersonality as such), linking up each human being to all other human beings, is discussed.
