Alexandru Marcoci and Alexandra Oprea. Free Speech, Toleration, and the Mission of the University. Under review Abstract

What should be the rules governing campus speech in a democratic society? The question is especially pressing given the university’s role in shaping democratic citizens and democratic elites. In this paper, we argue that both those in favor of robust protections for campus speech and those promoting stricter regulation of speech implicitly assume that their preferred policies lead to tolerant, open-minded and inquisitive students and citizens. However, neither side explains exactly how their speech-related recommendations would achieve this goal. This paper explores the problems with the possible causal mechanisms that underpin their arguments and makes the case that we should focus more on “output” measures of toleration rather than “input” measures in matters related to campus speech.

Alexandru Marcoci, Mark Burgman and Ans Vercammen. Reassessing the benefits of group discussion in the Wason selection task. Under review Abstract

Do interactive groups outperform individual reasoners on intellective tasks? Studies of the Wason selection task purport to demonstrate substantial benefits of group discussion but have so far been based on student samples. In this paper we investigate the benefits of group interaction for a sample of the general population and show that the effect of discussion we should expect in the real world is much less impressive.

(2021). Predicting Reliability Through Structured Expert Elicitation with Replicats (Collaborative Assessments for Trustworthy Science). Preprint available at MetaArXiv (February 22, 2021). Under review Abstract

Replication is a hallmark of scientific research. As replications of individual studies are resource intensive, techniques for predicting the replicability are required. We introduce a new technique to evaluating replicability, the repliCATS (Collaborative Assessments for Trustworthy Science) process, a structured expert elicitation approach based on the IDEA protocol. The repliCATS process is delivered through an underpinning online platform and applied to the evaluation of research claims in social and behavioural sciences. This process can be deployed for both rapid assessment of small numbers of claims, and assessment of high volumes of claims over an extended period. Pilot data suggests that the accuracy of the repliCATS process meets or exceeds that of other techniques used to predict replicability. An important advantage of the repliCATS process is that it collects qualitative data that has the potential to assist with problems like understanding the limits of generalizability of scientific claims. The repliCATS process has potential applications in alternative peer review and in the allocation of effort for replication studies.

Andrea Griffin, Matt Hayward, Ans Vercammen, Karen Makuch and Alexandru Marcoci. (Eds.). The Role of Compassion in Conservation Science and Practice: Lessons From the Field. Special Issue in Frontiers in Psychology (Submission deadline: 13 October 2021) CFP

As the biodiversity crisis continues to deepen, calls for an overhaul of conservation science have emerged. Traditionally, conservation was a discipline focused on studying the biology and ecology of populations, individual species, multi-species assemblages, and ecosystems. It has since broadened to recognize the important skills experts from a range of disciplines provide to conserving biodiversity. More recently, some are arguing that summoning compassion for individuals is needed to transform the meaning of conservation and the relationships between conservationists and the natural world. This transformation includes allowing for compassion to permeate conservation practice, from the conduct of individuals to the policies and institutions that govern conservation actions.
The role of compassion in conservation is currently a matter of significant debate. Our vision for this Frontiers Research Topic is to create a space where a collection of interdisciplinary views and perspectives can be collated to offer a synthesis to guide future research directions and inform practice. Conservation science is a relatively young field and might benefit from the conceptual and empirical progress made in more foundational disciplines.
We solicit contributions from fields as diverse as psychology, neuroscience, philosophy, biology, medicine, and law, in so far as they explicitly address the relationships between human cognition, emotion, attitudes, behavior, and decision making and how this relates to the practice of compassion. This may be in the form of conceptual clarifications and developments, empirical or modeling research, or practitioner frameworks. At this stage, we are not soliciting Opinion or Perspective pieces.
We are particularly interested in contributions that explain or highlight how other fields (e.g. medicine, the military) deal with moral dilemmas where the rights of, and compassion for, individuals may have to be traded off against societal benefit or the common good. All contributions should highlight the relevance of the work to conservation science (in a broad sense). The guest editors are available to work with authors from other disciplines to facilitate interdisciplinary dialogue and provide direction to ensure a good fit with the journal and special section.
The overall aim for this Frontiers Research Topic is to contribute to existing dialogues, encourage new collaborations, and raise novel challenges.

Luc Bovens and Alexandru Marcoci. The Gender-Neutral Bathroom: A New Frame and Some Nudges. Behavioural Public Policy, 1-24 Abstract

Gender-neutral bathrooms are usually framed as an accommodation for trans and other gender non-conforming individuals. In this paper we show that the benefits of gender-neutral bathrooms are much broader. First, our simulations show that gender-neutral bathrooms reduce average waiting times: while waiting times for women go down invariably, waiting times for men either go down or slightly increase depending on usage intensity, occupancy time differentials, and the presence of urinals. Second, our result can be turned on its head: firms have an opportunity to reduce the number of facilities and cut costs by making them all gender-neutral without increasing waiting times. These observations can be used to reframe the gender-neutral bathrooms debate so that they appeal to a larger constituency, cutting across the usual dividing lines in the “bathroom wars”. Finally, there are improved designs and behavioural strategies that can help overcome resistance. We explore what strategies can be invoked to mitigate the objections that gender-neutral bathrooms (1) are unsafe; (2) elicit discomfort; and (3) are unhygienic.

Groups have access to more diverse information and typically outperform individuals on problem solving tasks. Crowdsolving utilises this principle to generate novel and/or superior solutions to intellective tasks by pooling the inputs from a distributed online crowd. However, it is unclear whether this particular instance of “wisdom of the crowd” can overcome the influence of potent cognitive biases that habitually lead individuals to commit reasoning errors. We empirically test the prevalence of cognitive bias on a popular crowdsourcing platform, examining susceptibility to bias of online panels at the individual and aggregate levels. We then investigate the use of the Cognitive Reflection Test, notable for its predictive validity for real-life reasoning, as a screening tool to improve collective performance. We find that systematic biases in crowdsourced answers are not as prevalent as anticipated, but when they occur, biases are amplified with increasing group size, as predicted by the Condorcet Jury Theorem. The results further suggest that pre-screening individuals with the Cognitive Reflection Test can substantially enhance collective judgement and improve crowdsolving performance.

Alexandru Marcoci and James Nguyen. (2020). Judgement aggregation in scientific collaborations: The case for waiving expertise. Studies in History and Philosophy of Science Part A 84, 66-74 Abstract

The fragmentation of academic disciplines forces individuals to specialise. In doing so, they become experts over their narrow area of research. However, ambitious scientific projects, such as the search for gravitational waves, require them to come together and collaborate across disciplinary borders. How should scientists with expertise in different disciplines treat each others' expert claims? An intuitive answer is that the collaboration should defer to the opinions of experts. In this paper we show that under certain seemingly innocuous assumptions, this intuitive answer gives rise to an impossibility result when it comes to aggregating the beliefs of experts to deliver the beliefs of a collaboration as a whole. We then argue that when experts' beliefs come into conflict, they should waive their expert status.

In CogSIMA 2020 (IEEE Conference on Cognitive and Computational Aspects of Situation Management, Victoria, BC, Canada), 1-9 Abstract

Groups often struggle to reach decisions, especially when populations are strongly divided by conflicting views. Traditional methods for collective decision-making involve polling individuals and aggregating results. In recent years, a new method called Artificial Swarm Intelligence (ASI) has been developed that enables networked human groups to deliberate in real-time systems, moderated by artificial intelligence algorithms. While traditional voting methods aggregate input provided by isolated participants, Swarm-based methods enable participants to influence each other and converge on solutions together. In this study we compare the output of traditional methods such as Majority vote and Borda count to the Swarm method on a set of divisive policy issues. We find that the rankings generated using ASI and the Borda Count methods are often rated as significantly more satisfactory than those generated by the Majority vote system (p<0.05). This result held for both the population that generated the rankings (the “in-group”) and the population that did not (the “out-group”): the in-group ranked the Swarm prioritizations as 9.6% more satisfactory than the Majority prioritizations, while the out-group ranked the Swarm prioritizations as 6.5% more satisfactory than the Majority prioritizations. This effect also held even when the out-group was subject to a demographic sampling bias of 10% (i.e. the out-group was composed of 10% more Labour voters than the in-group). The Swarm method was the only method to be perceived as more satisfactory to the “out-group” than the voting group.

Alexandru Marcoci and James Nguyen. (2019).Objectivity, ambiguity and theory choice. Erkenntnis 84(2), 343–357 Abstract

Kuhn argued that scientific theory choice is, in some sense, a rational matter, but one that is not fully determined by shared objective scientific virtues like accuracy, simplicity, and scope. Okasha imports Arrow's impossibility theorem into the context of theory choice to show that rather than not fully determining theory choice, these virtues cannot determine it at all. If Okasha is right, then there is no function (satisfying certain desirable conditions) from 'preference' rankings supplied by scientific virtues over competing theories (or models, or hypotheses) to a single all-things-considered ranking. This threatens the rationality of science. In this paper we show that if Kuhn's claims about the role that subjective elements play in theory choice are taken seriously, then the threat dissolves.

In the wake of 9/11 and the war in Iraq, the Office of the Director of National Intelligence adopted Intelligence Community Directive (ICD) 203 – a list of analytic tradecraft standards – and appointed an ombudsman charged with monitoring their implementation. In this paper, we identify three assumptions behind ICD203: (1) tradecraft standards can be employed consistently; (2) tradecraft standards sufficiently capture the key elements of good reasoning; and (3) good reasoning leads to more accurate judgments. We then report on two controlled experiments that uncover operational constraints in the reliable application of the ICD203 criteria for the assessment of intelligence products.

Better together: Reliable application of the post-9/11 and post-Iraq US intelligence tradecraft standards requires collective analysis. Frontiers in Psychology 9, 2634 Abstract

Background. The events of 9/11 and the October 2002 National Intelligence Estimate on Iraq's Continuing Programs for Weapons of Mass Destruction precipitated fundamental changes within the US Intelligence Community. As part of the reform, analytic tradecraft standards were revised and codified into a policy document – Intelligence Community Directive (ICD) 203 – and an analytic ombudsman was appointed in the newly created Office for the Director of National Intelligence to ensure compliance across the intelligence community. In this paper we investigate the untested assumption that the ICD203 criteria can facilitate reliable evaluations of analytic products.
Method. Fifteen independent raters used a rubric based on the ICD203 criteria to assess the quality of reasoning of 64 analytical reports generated in response to hypothetical intelligence problems. We calculated the intra-class correlation coefficients for single and group-aggregated assessments.
Results. Despite general training and rater calibration, the reliability of individual assessments was poor. However, aggregate ratings showed good to excellent reliability.
Conclusions. Given that real problems will be more difficult and complex than our hypothetical case studies, we advise that groups of at least three raters are required to obtain reliable quality control procedures for intelligence products. Our study sets limits on assessment reliability and provides a basis for further evaluation of the predictive validity of intelligence reports generated in compliance with the tradecraft standards.

Alexandru Marcoci. (2018). On a dilemma of redistribution. Dialectica 72(3), 453-460 Abstract

McKenzie Alexander presents a dilemma for a social planner who wants to correct the unfair distribution of an indivisible good between two equally worthy individuals or groups: either she guarantees a fair outcome, or she follows a fair procedure (but not both). In this paper I show that this dilemma only holds if the social planner can redistribute the good in question at most once. To wit, the bias of the initial distribution always washes out when we allow for sufficiently many redistributions.

"What’s not to love about gender-neutral restrooms?" ask Bovens and Marcoci. Their spread could only come about trough a sensitive mix of good design and nudges; working on social norms and behaviours. Some discomforts may, however, prove to be beyond nudging, and an incremental, learning approach is probably required.

In a recent paper, Samir Okasha imports Arrow's impossibility theorem into the context of theory choice. He shows that there is no function (satisfying certain desirable conditions) from profiles of preference rankings over competing theories, models or hypotheses provided by scientific virtues to a single all-things-considered ranking. This is a prima facie threat to the rationality of theory choice. In this paper we show this threat relies on an all-or-nothing understanding of scientific rationality and articulate instead a notion of rationality by degrees. The move from all-or-nothing rationality to rationality by degrees will allow us to argue that theory choice can be rational enough.
