Research comics for science communication
Dr Ulrike Hahn is interviewed about her research in the field of climate-related visual art. In particular, her work currently involves turning the insights and studies of other researchers into research comics. In addition to Dr Hahn’s current research, the interview draws on how research comics can help to make academic claims credible on the one hand, and accessible to the wider public on the other hand through the portrayal of characters to w…
Learning from conditional probabilities
Bayesianism, that is, the formal capturing of belief in terms of probabilities, has had a major impact in cognitive science. Decades of research have examined lay reasoners' learning and reasoning with probabilities. The bulk of that research has concerned the response to new evidence. That response will depend on the conditional probabilities a reasoner assumes, yet little research has addressed the question of how reasoners respond when they ar…
The problem of dependency
It is a wide-spread assumption that multiple pieces of evidence, whether they involve measurements or testimony, provide stronger evidential support when they are independent than when they are not. The standard view is that non-independence creates redundancy and leads to over-confidence (see e.g., Soll in Cogn Psychol 38(2):317–346, 1999; Nisbett and Ross in Human inference: strategies and shortcomings of social judgment. Prentice Hall, New Jer…
Confirmation bias and the plausible distribution of evidence
How large language models can reshape collective intelligence
The impact of explanations as communicative acts on belief in a claim
Providing an explanation is a communicative act. It involves an explainee, a person who receives an explanation, and an explainer, a person (or sometimes a machine) who provides an explanation. The majority of research on explanation has focused on how explanations alter explainees' beliefs. However, one general feature of communicative acts is that they also provide information about the speaker (explainer). Work on argumentation suggests that t…
Similarity and structured representation in human and nonhuman apes
How we judge the similarity between objects in the world is connected ultimately to how we represent those objects. It has been argued extensively that object representations in humans are 'structured' in nature, meaning that both individual features and the relations between them can influence similarity. In contrast, popular models within comparative psychology assume that nonhuman species appreciate only surface-level, featural similarities. B…
Mirror or Hammer? News Media Coverage of Climate-Related Art
A growing momentum of artists and cultural institutions addressing climate change in their works and exhibitions can be observed in recent years. It is important to understand how such art is covered in quality newspapers because they can give meaning and importance to climate change, and cultural journalists act as mediators between cultural producers and consumers. This research asks: How is exhibited, visual climate-related art presented and e…
Individuals, Collectives, and Individuals in Collectives
Our beliefs are inextricably shaped through communication with others. Furthermore, even conversation we conduct in pairs may itself be taking place across a wider, connected social network. Our communications, and with that our thoughts, are consequently typically those of individuals in collectives. This has fundamental consequences with respect to how our beliefs are shaped. This article examines the role of dependence on our beliefs and seeks…
Science Communication as a Collective Intelligence Endeavor
Effective science communication is challenging when scientific messages are informed by a continually updating evidence base and must often compete against misinformation. We argue that we need a new program of science communication as collective intelligence—a collaborative approach, supported by technology. This would have four key advantages over the typical model where scientists communicate as individuals: scientific messages would be inform…

On the generality and cognitive basis of base-rate neglect
Base rate neglect refers to people's apparent tendency to underweight or even ignore base rate information when estimating posterior probabilities for events, such as the probability that a person with a positive cancer-test outcome actually does have cancer. While often replicated, almost all evidence for the phenomenon comes from studies that used problems with extremely low base rates, high hit rates, and low false alarm rates. It is currently…
Artistic Imaginations of Climate Change
Climate change has gained traction in artists' works and exhibitions. This research aims at gaining a better understanding of visual artists who create climate-related art and are/were located in the central art market countries of the United States of America, the United Kingdom, and Germany—countries with considerable contributions to climate change and responsibility for action. Responding to calls for the further involvement of the humanities…
When Science Becomes Embroiled in Conflict
We explore the common attributes of political conflicts in which scientific findings have a central role, using the COVID-19 pandemic as a case study, but also drawing on long-standing conflicts over climate change and vaccinations. We analyze situations in which the systematic spread of disinformation or conspiracy theories undermines public trust in the work of scientists and prevents policy from being informed by the best available evidence. W…
True clauses and false connections
Indicative conditionals—that is, sentences typically, though not exclusively, of the form “If p, (then) q,”—belong to the most puzzling phenomena of language. One of the puzzles that has recently attracted attention of psychologists of reasoning stems from the fact that on the majority of accounts of indicative conditionals, “If p, (then) q” can be true, or at least highly acceptable, even when there is no meaningful connection between p and q. C…
In the Space of Reasonable Doubt
Formal models of source reliability
The paper introduces, compares and contrasts formal models of source reliability proposed in the epistemology literature, in particular the prominent models of Bovens and Hartmann (Bayesian epistemology, Oxford University Press, Oxford, 2003) and Olsson (Episteme 8(02):127–143, 2011). All are Bayesian models seeking to provide normative guidance, yet they differ subtly in assumptions and resulting behavior. Models are evaluated both on conceptual…
Reconsidering evidence of moral contagion in online social networks
Conditionals and testimony
Conditionals and conditional reasoning have been a long-standing focus of research across a number of disciplines, ranging from psychology through linguistics to philosophy. But almost no work has concerned itself with the question of how hearing or reading a conditional changes our beliefs. Given that we acquire much-perhaps most-of what we believe through the testimony of others, the simple matter of acquiring conditionals via others' assertion…
Dependencies in evidential reports
Visualizing climate change
Artists creatively use scientific data in artistic information visualizations (AIVs) to address climate change. Yet, it is unclear how effective they are in making viewers consider climate change as important. To assess their reception, this research studies and compares AIVs in relation to four additional visual forms, which are common in the communication of climate change (information visualizations, news photos, digital art visuals and cartoo…
Truth tracking performance of social networks
Our beliefs and opinions are shaped by others, making our social networks crucial in determining what we believe to be true. Sometimes this is for the good because our peers help us form a more accurate opinion. Sometimes it is for the worse because we are led astray. In this context, we address via agent-based computer simulations the extent to which patterns of connectivity within our social networks affect the likelihood that initially undecid…
The potential power of experience in communications of expert consensus levels
Understanding the scientific consensus on anthropogenic climate change has been dubbed a ‘gateway belief’ to engaging people in sustainable behaviour. We consider the question of how the impact of a consensus communication can be maximised. Firstly, the credibility of the communicator should be maximised. One way of achieving this is to present the opinions of a sample of scientists directly to individuals. The decision-making literature suggests…

Applying the value of equality unequally
Across 4 experiments, the authors investigated the role of value instantiation in bridging the gap between abstract social values and behavior in specific situations. They predicted and found that participants engaged in more egalitarian behavior (point allocation using the minimal group paradigm) after contemplating a typical instantiation of the value of equality compared to an atypical instantiation or a control condition that simply made the …

Language acquisition also needs non-connectionist models
Rethinking innateness is a timely volume which forcefully demonstrates the importance of modelling in understanding development, ‘innateness’, and the nature of change. It provides an inspiring vision of what developmental psychology could one day be like, linking behaviour and biology via connectionist models. However, Rispoli's worry about the book's potential for detrimental polarization does not seem unfounded. One aspect of the book that des…
So concepts aren't definitions, but do they have necessary or sufficient features
Rips (1989) is one of the most widely cited demonstrations of the relevance of critical features in conceptual structure. A critical feature will impose constraints on how an object is classified, regardless of other factors, such as overall similarity. We review and clarify critical features proposals in terms of whether an assumption is being made about necessary features, sufficient features, or both (i.e. a definition). On the basis of this, …
Determinants of Wordlikeness
A Bayesian Approach to Informal Argument Fallacies
The rationality of informal argumentation
Classical informal reasoning "fallacies," for example, begging the question or arguing from ignorance, while ubiquitous in everyday argumentation, have been subject to little systematic investigation in cognitive psychology. In this article it is argued that these "fallacies" provide a rich taxonomy of argument forms that can be differentially strong, dependent on their content. A Bayesian theory of content-dependent argument strength is presente…
Catalan Children's Sensitivity to the Discourse Constraints Imposed by Different Kinds of Question
In an investigation of discourse sensitivity, Catalan-speaking children aged 4 to 8 years were asked two different questions in a picture description task. One was a wide-focus question ("What is happening?"); the other was a narrow-focus question ("What is happening to 'the patient'?"). Children of all age groups displayed sensitivity to the various discourse constraints imposed by the two different questions, responding both with changes to wor…

Rational argument, rational inference
Reasoning researchers within cognitive psychology have spent decades examining the extent to which human inference measures up to normative standards. Work here has been dominated by logic, but logic has little to say about most everyday, informal arguments. Empirical work on argumentation within psychology and education has studied the development and improvement of argumentation skills, but has been theoretically limited to broad structural cha…
