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. More generally, the outcome of this study may have significant legal implications in many jurisdictions.

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.

Sunk cost effects for time versus money: Replication and extensions Registered Report of Soman (2001)

Mixed evidence for the hypothesis that sunk cost effects are weaker for time than money

Recommended by ORCID_LOGO based on reviews by Christopher Olivola and Dilip Soman
The sunk cost fallacy is a cognitive bias in which people persist with a decision that is no longer optimal because of previous resources they have invested (now considered to be spent or “sunk”). Most of us will have heard sunk costs reflected in the saying “throwing good money after bad”, but sunk costs can, in theory, occur more broadly, whether for money, time or any other resource-limited investment. The sunk cost effect for money has been widely studied and appears robust; in contrast, the sunk cost effect for time is more uncertain, and is potentially moderated by the age of respondents (and likely resource availability), the fact that time is irreplaceable, and the tendency for people to account for time less easily than they do for money. In an impactful study, Soman (2001) found that the sunk cost effect for time was indeed weaker than for money, although this finding has not been widely replicated.
 
In the current study, Petrov et al. (2023) replicated three studies (1, 2 and 5) from Soman (2001), asking whether sunk costs are weaker for time than for money, and then testing whether the relative absence of a sunk time cost arises from the inability of participants to account for time or due to more rational beliefs in the evaluation of past time investments.
 
Results provided mixed support for the original findings. Consistent with Soman (2001), the sunk cost effect for money was reliably stronger than for time in Study 1; however, sunk costs for both money and time were comparable in Study 2 (and if anything, slightly stronger for time). The indirect replication of Study 5 from Soman (2001) found that the sunk cost effect for time was not significantly influenced by accounting for time, either using education or by highlighting opportunity costs. Robustness checks confirmed the main preregistered outcomes while also ruling out a range of potential alternative explanations. Overall, the results suggest that that sunk cost effects for time are more context-dependent and empirically volatile than sunk costs for money.

A multilab investigation into the N2pc as an indicator of attentional selectivity: Direct replication of Eimer (1996)

Is the N2pc a correlate of attentional selection? An #EEGManyLabs multi-lab registered replication of Eimer (1996)

Recommended by ORCID_LOGO based on reviews by Reny Baykova and Clayton Hickey
The N2pc is a lateralised ERP component that is often interpreted as a marker of attentional allocation, so much so that it is frequently used a tool in the attention literature for inferring that a stimulus was attentionally processed. This interpretation of N2pc can be traced back to the seminal work of Eimer (1996), which has been conceptually replicated many times but has never been replicated directly.
 
This registered direct replication by Constant et al. (2023) forms part of a larger series of large-scale, multi-lab replications of highly influential EEG papers by the #EEGManyLabs project (Pavlov et al., 2021). Seven labs (with the potential for more to sign up later), will conduct high-powered replications of the critical Experiment 2 of Eimer (1996), where in the crucial conditions, participants discriminate a target letter (M vs W) or colour (blue vs green) in the presence of a distractor. Using four preprocessing pipelines, including the original, the authors will test whether the N2pc is observed over parieto-occipital electrodes contralateral to target presentation.

Personal factors and group creativity characteristics: A correlational meta-analysis

Which personal factors are associated with group creativity?

Recommended by ORCID_LOGO

What determines whether groups of people can come up with ideas that are both original and useful? Since the 1960s, this question has been intensively studied with the help of more or less structured group creativity activities such as brainstorming or creative problem solving, with subsequent rating of the generated ideas.

In this line of research, personal factors—such as personality traits, and other interindividual differences in emotion and cognition—have received substantial attention as potential correlates of creative outcomes of group activities. This has spawned a sprawling literature that, to date, has not yet been synthesized. Thus, empirical findings in this literature, which are also sometimes contradictory, have not yet been well-integrated.

In the present study, Fillon et al. (2022) conducted the first meta-analysis of correlations between personal factors and group creativity outcomes. The authors searched and synthesized the existing published literature according to predetermined criteria to (1) assess the overall relationship between a broad list of personal factors and creativity outcomes in group settings and (2) explore potential moderators of these relationships. 

In total, 11 studies could be included in the meta-analysis. They provided weak support for a positive correlation between self-efficacy and the three investigated group creative outcomes, number of ideas, originality of ideas, and usefulness of ideas. With respect to moderators, many of the planned analyses could not be conducted due to the low number of studies. The only finding that arose was weak evidence for the idea that time constraint moderates associations: relationships between personal factors and group creativity outcomes were slightly stronger for tasks limited to 20 minutes rather than 10 minutes. Statistical power overall was low across studies.

The authors conclude their meta-analysis with the observation that the available data on the topic are very limited. They suggest that to improve our knowledge of the topic, future studies should adhere to standardized creativity methods and protocols and implement expert ratings of creativity. They also call for increasing the availability of raw data in this field of study to improve the accumulation of knowledge about links between personal factors and the creative performance of groups.

The Stage 2 manuscript was evaluated over one round of in-depth review provided by the recommender and Chris Chambers, as the original reviewers were no longer available.

Personal factors and group creativity characteristics: A correlational meta-analysis

Which personal factors are associated with group creativity?

Recommended by ORCID_LOGO and ORCID_LOGO based on reviews by Evan Carter and Greg Feist
What determines whether groups of people can come up with ideas that are both original and useful? Since the 1960s, this question has been intensively studied with the help of more or less structured group creativity activities such as brainstorming or creative problem solving, with subsequent rating of the generated ideas.
 
In this line of research, personal factors—such as personality traits, and other interindividual differences in emotion and cognition—have received substantial attention as potential correlates of creative outcomes of group activities. This has spawned a sprawling literature that, to date, has not yet been synthesized. Thus, empirical findings in this literature, which are also sometimes contradictory, have not yet been well-integrated.
 
In the present study, Fillon et al. (2022) will conduct the first meta-analysis of correlations between personal factors and group creativity outcomes. The authors will search and synthesize the existing (published and unpublished) literature according to predetermined criteria to (1) assess the overall relationship between a broad list of personal factors and creativity outcomes in group settings and (2) explore potential moderators of these relationships. The latter research question includes substantive moderators, such as familiarity between group members, group size, and type of task, but also publication status.
 
The Stage 1 manuscript was evaluated over five rounds of in depth-review. Based on detailed responses to reviewers’ and the recommenders’ comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance.
