Justice in the Eye of the Beholder: How Comparison Framing Affects the Perception of Global Inequality Through Social Emotions and Justice Sensitivity

Why are there variations in perceptions of inequality?

Recommended by ORCID_LOGO based on reviews by Mario Gollwitzer and Sa-Kiera Hudson
Inequalities in income, wealth, and opportunities are rampant both between and within nations around the world. Making strides to rectify inequalities requires examining how people come to understand them as well as the psychological processes that translate those understandings into reparative actions. There is some evidence for a “comparative framing effect,” in which the group that is initially referenced impacts judgements by communicating salient information and the appropriate reference point. Research on this comparative framing effect suggests that focusing on disadvantage, relative to advantage, leads to a more negative assessment and intentions to engage in action to reduce the inequality. 
 
In two pilot studies (reported in the current proposal) focused on global inequalities (low-income vs high-income countries), Schnepf et al. (2023) did not find evidence for a main effect of framing on perceived legitimacy of the inequality or intentions to engage in action. They did, however, find some evidence for an interaction with the perceived size of the inequality. When the low-income country was the subject of the comparison, larger perceptions of the size of the inequality were associated with greater intentions to engage in action (both studies) and greater perceptions of the differences as illegitimate (Study 1 only). Moreover, they found some evidence in both studies that negative social emotions such as guilt and shame were the mechanism that explained why perceiving greater inequality in the low-income framing condition was associated with the outcomes. 
 
In the current study, Schnepf et al. (2023) build upon these two pilot studies to conduct a high-quality replication and a stronger test of their hypotheses. Most notably, the proposed Registered Report uses a much larger sample, providing adequate statistical power to detect relatively small interaction effects. Additionally, the proposed project manipulates the size of the inequality that is being evaluated, rather than relying on participants’ perceptions. Finally, the study includes “justice sensitivity,” or the degree to which individuals assess inequality as unfair as an additional hypothesized moderator, and “social dominance orientation” as an exploratory moderator. Along with the pilot studies, the proposed project will represent a strong test of several hypotheses relevant to many different areas of social and personality psychology.

Functional MRI brain state occupancy in the presence of cerebral small vessel disease -- pre-registration for a replication analysis of the Hamburg City Health Study

Testing the replicability of dynamic functional connectivity correlates of cerebral small vessel disease in the Hamburg City Health Study

Recommended by ORCID_LOGO based on reviews by Olivia Hamilton and 1 anonymous reviewer
A recent study has reported that the extent of cerebral small vessel disease (cSVD) shows associations with dynamic functional connectivity measures obtained from resting state functional MRI scans (Schlemm et al, 2022). Specifically, when the functional scan was parsed into time spent in discrete brain states, the proportion of time spent in the two most-occupied states was negatively related to a structural indicator of cSVD (volume of white matter hyperintensities of presumed vascular origin). This measure of 'fractional occupancy' was also associated with cognitive impairment as indicated by longer time to complete part B of the Trail Making Test. These findings were based on the analysis of data from 988 participants in the Hamburg City Health Study (HCHS).
 
In the present Registered Report, Schlemm (2023) will test whether these associations can be replicated in an independent sample of participants from the HCHS, not included in the earlier analysis (projected N for new analysis ~1500). In addition to the two main hypothesis tests, an exploratory multiverse analysis will be reported, systematically varying some key parameters of the MRI processing pipeline to provide further information about the robustness of the outcome of the primary hypothesis test. 
 
The Stage 1 plan was refined over two rounds of review by two relevant experts, with additional input from the recommender on the specification of the registered plan. Both reviewers are satisfied that the plan constitutes an appropriate approach to this question, and on the basis of their comments and his own evaluation, the recommender judged that the Stage 1 report meets the criteria for in-principle acceptance.

Reference points and decision-making: Impact of status quo and defaults in a conceptual replication and extensions Registered Report of Dinner et al. (2011)

Understanding the impact of status quo bias and the default effect on decision-making

Recommended by ORCID_LOGO based on reviews by Laurens van Gestel, Julia Nolte and Sylvain Chabé-Ferret
Everyday decisions can often be biased by how different options are presented and which choices were made previously, over and above whichever option is rationally preferable. Two such major biases in judgment and decision-masking are status quo bias and the default effect. The status quo bias reflects a tendency for people to choose an option that has already been implemented or represents the current state of affairs (for instance, choosing to remain with a current energy supplier rather than switching to a different one, even when the current supplier provides less value for money), while the default effect is a bias toward taking a course of action that would occur automatically in the absence of an active choice (such as the pre-selected energy supplier in questionnaire). Status quo bias and default effects can overlap or diverge: the status quo option will often be the same as the default, while on other occasions the default option in a choice set will be determined by other factors and differ from the option that was already implemented.
 
In the current study, Yam and Feldman (2023) propose a replication and extension of an influential study by Dinner et al. (2011) that purported to examine default effects but, arguably, actually studied its nearby cousin, status quo bias. Using a large online sample, the authors will independently test for the existence of both status quo bias and the default effect, before then asking whether (and if so how) status quo bias and default effects interact and how they are related to several potential explanatory variables, including perceived effort (which may be lower for the status quo or default) and endorsements (whether through direct recommendations or indirectly through perceived norms). The authors also build in additional manipulation checks and comprehension checks, in addition to exploratory analyses examining (among other variables), the political orientation of participants.

Cortical plasticity of the tactile mirror system in borderline personality disorder

Is borderline personality disorder linked to impairment of the tactile mirror system?

Recommended by ORCID_LOGO based on reviews by Zoltan Dienes and 2 anonymous reviewers
Borderline personality disorder (BPD) is a mental illness affecting ~1 in 100 people (Ellison et al., 2018), characterised by emotional dysregulation, impulsivity, a distorted sense of self, and a long-term pattern of unstable interpersonal relationships. Among this heterogenous range of symptoms is difficulty in the cognitive dimension of empathy, in particular understanding the perspectives of others, which in turn has been suggested to rely on the mirror neuron system, both in the motor and somatosensory domains. The integrity of the mirror system has therefore been a focus for understanding the possible causes or consequences of the disorder, with preliminary studies pointing to hypoactivity of neuronal areas associated with the mirror system in BPD (Mier et al., 2013).
 
In the current study, Zazio et al. (2023) will use crossmodal paired associative stimulation (cm-PAS) in which an image of a hand being touched is repeatedly paired with transcranial magnetic stimulation (TMS) of the primary somatosensory cortex (S1) to test the hypothesis that BPD is associated with a specific deficit in the tactile mirror system. In healthy controls, the close temporal coupling (20ms) between the visual depiction of tactile stimulation and TMS of S1 is expected boost tactile acuity and elevate the performance cost of incongruence in a task that manipulates visuo-tactile spatial congruity (VTSC) – effects that are thought to reflect the fidelity of the tactile mirror system.
 
In BPD patients, however, the authors make the crucial prediction that impairment of the tactile mirror system (if present) will lead to a reduced (or even non-existent) effect of cm-PAS on tactile acuity and VTSC task performance compared to healthy controls. To help ensure a severe test of this hypothesis, the design includes a variety of controls, including an attention check, control cm-PAS in which the inter-stimulus interval is increased to 100ms to break the close temporal coupling between visual stimulation and TMS, and a positive control to confirm that active cm-PAS (compared to control cm-PAS) produces the expected boost in tactile acuity in healthy controls.

Revisiting the “Belief in the law of small numbers”: Conceptual replication and extensions Registered Report of problems reviewed in Tversky and Kahneman (1971) [Stage 1]

Should we believe in the “belief in the law of small numbers?”

Recommended by ORCID_LOGO based on reviews by Romain Espinosa and Kariyushi Rao
Probability and randomness are foundational statistical concepts used not only throughout the sciences, but also in our daily lives to guide our behavior and make sense of the world. Their importance and widespread use may suggest that they are easy concepts to understand, yet that seems not to be the case. A classic article by Tversky and Kahneman (1971) on the “belief in the law of small numbers” revealed that professional psychologists tended to incorrectly perceive a small sample that is randomly drawn from a population as representative of that population. This finding has been hugely influential, inspiring myriad subsequent studies into error and bias when reasoning about probability. 
 
In the current study, Hong and Feldman (2023) propose a conceptual replication and extension of Tversky and Kahneman (1971). The original article was shockingly sparse on details regarding the method, sample, and findings, and, to our knowledge, has never been replicated. These facts are especially concerning given the foundational status that the article holds in the field. Hong and Feldman (2023) have developed a conceptual replication project, using the same approach and targeting the same claims from Tversky and Kahneman (1971), but modifying the wording of the stimuli for clarity and appropriateness for lay respondents. Although Tversky and Kahneman (1971) relied on professional psychologists as participants, many of their claims were not restricted to that population, but rather were generalized to all people—which is also how the findings have been subsequently applied. Thus, the change from professional to lay responders is entirely appropriate and the study will be diagnostic of the original claims.
 
Finally, Hong and Feldman (2023) extend the target study by manipulating the sample size indicated in the stimuli. Tversky and Kahneman (1971) relied on a single sample size in each scenario, leaving open the question as to how sample size might impact respondents’ reasoning. Accordingly, Hong and Feldman (2023) vary the sample size across the scenarios to determine whether participants answer differently as the sample size increases.

Licensing via credentials: Replication of Monin and Miller (2001) with extensions investigating the domain-specificity of moral credentials and the association between the credential effect and trait reputational concern

Revisiting moral licensing

Recommended by ORCID_LOGO based on reviews by Corey Cusimano, Marek Vranka, Štěpán Bahník and Ethan Meyers
Does being good free people up to be bad? A large literature in social psychology suggests that it might, with evidence that “moral licensing” gives people a perception that actions deemed morally questionable, or socially undesirable, will be tolerated more readily if they have demonstrated a past history of praiseworthy, moral behaviour. In a formative study, Monin and Miller (2001) reported that having a track record of moral credentials as being nonprejudiced (e.g. non-sexist or non-racist) increased the willingness of participants to later express a prejudiced attitude. For example, in their Study 2 they found that participants who built up their moral credit by selecting a Black woman in a hypothetical recruitment task were then more willing to then prefer a White man for a second job, compared to participants who did not have the opportunity to initially recommend a Black woman. These results have prompted a burgeoning literature on moral licensing, albeit one that is mixed and has been found to exhibit substantial publication bias.
 
In the current study, Xiao et al. (2023) propose a large online replication of Study 2 in Monin and Miller (2001), asking whether previous moral behaviours that furnish participants with moral credentials make them more likely to then engage in morally questionable behaviours. The authors will also extend earlier work by testing whether moral credentials license immoral behaviours more effectively in the same domain (e.g. within sex) than in a different domain (e.g. across sex and race), asking whether there is a negative relationship between expression of prejudice and trait reputational concern (fear of negative evaluation), and whether moral credentials attenuate any such observed relationship.

Revisiting the impact of affection on insurance purchase and claim decision-making: Replication and extensions Registered Report of Hsee and Kunreuther (2000)

Understanding how object-oriented emotional attachment influences economic response to loss

Recommended by ORCID_LOGO based on reviews by Bence Palfi, Rima-Maria Rahal and Fausto Gonzalez
Emotion is a well-established mediator of decision-making, including prospective economic decisions, but does it affect the way we respond economically to loss? According to classic economic theories, when an object is lost and cannot be recovered, our emotional attachment to that object should be irrelevant for decisions such as choosing whether to claim insurance or compensation. Intriguingly, however, this does not appear to be the case: in a series of experiments, Hsee and Kunreuther (2000) found that when people have higher affection towards an object, they are more sensitive to its loss and are more willing to claim compensation or purchase insurance for the object. They explained these findings according to an influential “consolation hypothesis” in which people see insurance compensation as means to mitigate against the emotional distress associated with property loss.
 
Using a large online sample (N=1000), Law and Feldman (2023) propose to replicate four of six studies from Hsee and Kunreuther (2000), each asking (primarily) whether people with higher affection towards an object are more willing to claim compensation or purchase insurance for that object. In each experiment, participants are randomly assigned to either a high affection group or a low affection group and then given a scenario in which the level of affection to an object is correspondingly manipulated while the monetary value is held constant. For example, for high affection: “You liked the now-damaged painting very much and you fell in love with it at first sight. Although you paid only $100, it was worth a lot more to you”, and for low affection: “You were not particularly crazy about the now-damaged painting. You paid $100 for it, and that’s about how much you think it was worth.” A range of dependent measures are then collected, including the maximum hours participants would be willing to spend driving to claim compensation, the maximum amount participants would be willing to pay for insurance, and how likely participants would be to claim compensation or purchase insurance. As part of the replication, the authors have also built in manipulation checks to confirm that the scenarios influenced participants' (imagined) level of affection for the object, and a range of exploratory analyses.

Communicating Dynamic Norms With Visual Cues

No short-term benefit of a dynamic norm intervention on reducing indicators of meat consumption

Recommended by ORCID_LOGO based on reviews by Gabriela Jiga-Boy
Human meat consumption is associated with a variety of risks to health, animal welfare, sustainability, and the environment (including greenhouse gas emissions and loss of biodiversity), prompting a growing research effort to develop psychological interventions to reduce it and encourage alternative diets. At the same time, although meat consumption remains the majority choice in the UK, its prevalence is declining, with the proportion of vegetarians and vegans increasing substantially over the last two decades.
 
One potential tool to accelerate behaviour change is to expose people to “dynamic norm” messaging, which, rather than providing static descriptive information about the prevalence of a desired behaviour, emphasises how the desired behaviour is changing over time so that people can begin to conform to the emerging trend. Although promising in theory, previous research offers mixed evidence on the effectiveness of dynamic norms in encouraging a reduction in meat consumption, with some studies suggesting benefits and others showing no effect or even counterproductive effects. The methodological rigour of some studies is also in question.
 
In the present study, Aldoh et al. (2023) investigated the effectiveness of dynamic norm information (compared to static norms) on several indicators of meat consumption, including interest, attitudes, and intentions toward reducing meat consumption, as well as self-reported meat consumption itself. Using an online sample of ~1500 participants, the authors also tested the role of visual cues (including data trend graphics) in causing any effects and explored the potential longevity of the intervention over a period of 7 days. Results revealed moderate evidence for no net effect of dynamic (compared to static) norm information on meat consumption outcomes, nor any positive change over the 7-day period. However, the addition of visual cues enhanced the effect of dynamic norm messages, suggesting potential avenues for increasing the potency of future messaging interventions.

Defacing biases in manual and automated quality assessments of structural MRI with MRIQC

The impact of removing facial features on quality measures of structural MRI scans

Recommended by ORCID_LOGO based on reviews by Catherine Morgan and Cassandra Gould van Praag
Data sharing is perhaps the most fundamental step for increasing the transparency and reproducibility of scientific research. However, the goals of open science must be tempered by ethical considerations, protecting the privacy and safety of research participants. Bridging this gap causes challenges for many fields, such as human neuroimaging. Brain images, as measured with magnetic resonance imaging (MRI), are unique to the participant and therefore contain identifying information by definition. One way to mitigate the risk to participants arising from public data sharing has been "defacing" the MRI scans, i.e., literally removing the part of the image that contains the face and surrounding tissue, while preserving the brain structure. This procedure however also removes information that is not (or at least minimally) identifiable. It also remains unclear whether defacing the images affects image quality and thus the information necessary for addressing many research questions.
 
The current study by Provins et al. (2023) seeks to address this question. Leveraging a publicly available "IXI dataset" comprising hundreds of T1-weighted structural MRI scans, they will assess the effect of defacing on manual and automatic estimates of image quality. Specifically, the researchers will compare image quality ratings by experts for a subset of 185 images. They hypothesise that images in which facial features have been removed are typically assigned higher quality ratings. Moreover, using a full data set of 580 images, which have been obtained across three scanning sites, they will also test the impact defacing MRI scans has on automated quality measures obtained with MRIQC software. The results of this study should have important implications for open science policy and for designing the optimal procedures for sharing structural MRI data in an ethical way. For example, if the authors' hypothesis is confirmed, studies relying on MRI quality measures might be better served by a custodianship model where identifiable data is shared under strict conditions, rather than relying on publishing defaced data.

Does Brooding Meaningfully Increase the Likelihood of Believing in a Conspiracy? A Registered Report

Does brooding increase conspiracy beliefs?

Recommended by ORCID_LOGO based on reviews by Matt Williams and 1 anonymous reviewer
The world is seemingly awash with conspiracy theories – from well-trodden examples such as fake Moon landings, the 9/11 truth movement, and Holocaust denial, to relative newcomers including COVID as a bioweapon, QAnon, and the belief that the science of climate change has been invented or falsified. While there is a public perception that conspiracy theories are becoming more prevalent, recent evidence suggests that the rate of conspiracism is relatively stable over time (Uscinski et al., 2022). At any point in history, it seems that a certain proportion of people find themselves vulnerable to conspiracy beliefs, but what distinguishes those who do from those who don’t, and what are the causal factors?
 
In the current study, Liekefett et al. (2023) investigate the critical role of rumination – a perseverative and repetitive focus on negative content leading to emotional distress. In particular, the authors ask whether one component of rumination referred to as brooding (dwelling on one’s worries and distressing emotions) has a specific causal role in the formation of conspiracy beliefs. In a series of preliminary experiments, the authors first established a procedure for successfully inducing rumination, identifying various boundary conditions and requirements for a successful design. In the proposed study (of up to N=1,638), they will then ask whether the induction of brooding causes a significant increase in conspiracy beliefs. Manipulation checks will be included to confirm intervention fidelity (independently of this hypothesis), and exploratory analyses will test the effect of various moderators, as well as the causal role of a complementary manipulation of reflection – a component of rumination in which attention is focused on the issue at hand rather than one’s emotions.
 
The Stage 1 manuscript was evaluated over two rounds of in-depth review. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).
