In this article, I argue that online echo chambers are in some cases and in some respects good. I do not attempt to refute arguments that they are harmful, but I argue that they are sometimes beneficial. In the first section, I argue that it is sometimes good to be insulated from views with which one disagrees. In the second section, I argue that the software-design principles that give rise to online echo chambers have a lot to recommend them. Further, (...) the opposing principle, serendipity, could give rise to serious harm, in light of the conclusion of the first section that sometimes we are better off being insulated from some content online. In the third section, I argue that polarization can be a useful tool for inculcating the appropriate attitudes in a person. (shrink)

Socioscientific issues receive considerable public attention and there are concerns that people in general are not able or willing to deal with information at odds with what they believe to be true. In this study, we focused on students’ beliefs about two controversial issues: whether consumption of the artificial sweetener aspartame and use of cell phones, respectively, represent any serious health risks. Our aim was to investigate whether students’ trust in the information was related to prior beliefs, the nature of (...) the message, and students’ critical reading strategies. Results showed interactions between prior beliefs about the issues and text condition (risk vs. no risk) on trust in conclusions that indicated a confirmation bias assumption. Additionally, students trusted conclusions ascertaining that there were risks more than conclusions ascertaining that there were no risks. Finally, students’ self-reported use of critical reading strategies implied less trust in both types of conclusions. (shrink)

Bias and prejudice are well known aspects of all societies and political arenas. They motivate a wide variety of fear-mongering policies and seem to be deeply ingrained in the hearts and minds of people, interfering with their reasoning and better judgement. In this paper, I explore how bias and prejudice come about and how they can be put to more productive use in a democratic context. Humans aren’t as rational as we might expect. We often fail to think logically and (...) applying abstract reasoning is a challenge. When concepts are difficult for us to grasp, we often use our pre-existing ideas and experiences. Our biases and pre-conceived notions allow us to make better sense of complex problems. Bias is unavoidable. If we accept that we have pre-existing beliefs and can identify them accurately, they can serve an epistemic purpose in deliberation. We can use bias and prejudice as the starting point for meaningful inquiry as well as critical self-reflection. In order to accomplish this we need to place a greater educational focus on critical thinking skills. This type of education develops both our specific skills for analysis, evaluation and problem solving, but also builds the essential dispositions for open-mindedness and tolerance that are essential for effective deliberation.

In this paper, I identify a form of epistemic insensitivity that occurs when someone fails to make proper use of the epistemic tools at their disposal in order to bring their beliefs in line with epistemically relevant evidence that is available to them. I call this kind of insensitivity agential insensitivity because it stems from the epistemic behavior of an individual agent. Agential insensitivity can manifest as a failure to either attend to relevant and available evidence, or appropriately interpret evidence (...) that is attended to. The concept of agential insensitivity allows us to conceptualize the kind of not-knowing involved in forms of ignorance that are cultivated and maintained by individual agents, especially when this ignorance is enabled or encouraged by social structures. I use the skepticism about racial disparities in policing practices that is displayed by many white Americans as a lens for exploring this connection. Understanding agential insensitivity thus provides insight into both social and epistemic phenomena. (shrink)

Mercier & Sperber (M&S) argue for their argumentative theory in terms of communicative abilities. Insights can be gained by extending the discussion beyond human reasoning to rodent and robot navigation. The selection of arguments and conclusions that are mutually reinforcing can be cast as a form of abductive reasoning that I argue underlies the construction of cognitive maps in navigation tasks.

Many experiments suggest that participants are more critical of arguments that challenge their views or that come from untrustworthy sources. However, other results suggest that this might not be true of demonstrative arguments. A series of four experiments tested whether people are influenced by two factors when they evaluate demonstrative arguments: how confident they are in the answer being challenged by the argument, and how much they trust the source of the argument. Participants were not affected by their confidence in (...) the answer challenged by the argument. By contrast, they were sometimes affected by their trust in the argument’s source. Analyses of reaction times and transfer problems suggest that source trustworthiness did not directly affect argument evaluation, but affected instead the number of times the participants considered the arguments. Our results thus suggest that people can evaluate demonstrative arguments objectively. In conclusion, we defend the hypothesis that people might also be able to evaluate non-demonstrative arguments objectively. These results support the predictions of the argumentative theory of reasoning. (shrink)

Mercier & Sperber (M&S) claim that the phenomenon of belief bias provides fundamental support for their argumentative theory and its basis in intuitive judgement. We propose that chronometric evidence necessitates a more nuanced account of belief bias that is not readily captured by argumentative theory.

Short abstract (98 words). Reasoning is generally seen as a means to improve knowledge and make better decisions. However, much evidence shows that reasoning often leads to epistemic distortions and poor decisions. This suggests that the function of reasoning should be rethought. Our hypothesis is that the function of reasoning is argumentative. It is to devise and evaluate arguments intended to persuade. Reasoning so conceived is adaptive given humans’ exceptional dependence on communication and vulnerability to misinformation. A wide range of (...) evidence in the psychology of reasoning and decision making can be reinterpreted and better explained in the light of this hypothesis. (shrink)

In this article, we demonstrate that individuals use motivated reasoning to convince themselves that their self-serving behavior is justified, which in turn affects the distribution of resources in business situations. Specifically, we explore how ambiguous contextual cues and individual beliefs can jointly form motivated reasoning. Across two experimental studies, we find that whereas individual ideologies that endorse status hierarchies can strengthen the relationship between contextual ambiguity and motivated reasoning, individual beliefs rooted in fairness and equality can weaken it. Our findings (...) contribute to person–situation theories of business ethics and provide evidence that two ubiquitous factors in business organizations—contextual ambiguity and social dominance orientation—give rise to motivated reasoning, enabling decision makers to engage in self-serving distributions of resources.

Two experiments investigated whether moral evaluations of organ transplantation influence judgments of death and causation. Participants’ beliefs about whether an unconscious organ donor was dead and whether organ removal caused death in a hypothetical vignette varied depending on the moral valence of the vignette. Those who were randomly assigned to the good condition were more likely to believe that the donor was dead prior to organ removal and that organ removal did not cause death. Furthermore, attitudes toward euthanasia and organ (...) donation independently predicted judgments of death and causation, regardless of experimental condition. The results are discussed in light of the framework of motivated reasoning, in which motivation influences the selection of cognitive processes and representations applied to a given domain, as well as Knobe’s person-as-moralist model, in which many basic concepts are appropriately imbued with moral features. On either explanatory framework, these data cast doubt on the psychological legitimacy of the mainstream justification for vital organ procurement from heart-beating donors, which holds that neurological criteria for death are scientifically justified, independently of concerns about organ transplantation. These data suggest that, rather than concluding that organ removal is permissible because the donor is dead, people may believe that the donor is dead because they believe organ removal to be permissible.

What, if anything, is epistemically wrong with beliefs involving accurate statistical generalizations about demographic groups? This paper argues that there is a perfectly general, underappreciated epistemic flaw which affects both ethically charged and uncharged statistical generalizations. Though common to both, this flaw can also explain why demographic statistical generalizations give rise to the concerns they do. To identify this flaw, we need to distinguish between the accuracy and the projectability of statistical beliefs. Statistical beliefs are accompanied by an implicit representation (...) of the statistic's modal profile. Their modal profile determines the circumstances in which they can legitimately be projected to unobserved instances. Errors in that implicit content can be compatible with the accuracy of the “bare” statistic, whilst systematically leading to downstream errors in reasoning, in a manner which reveals an epistemic flaw with an important aspect of the belief state itself.

Understanding how people form opinions about climate change has proven to be challenging. One of the most common approaches to studying climate change beliefs is to assume people employ motivated reasoning. We first detail how scholars in this area have applied motivated reasoning perspectives, identifying a variety of different judgment goals on which they have focused. We next argue that existing findings fail to conclusively show motivated reasoning, much less isolate which specific goals guide opinion formation about climate change. Then, (...) we describe a novel motivational systems framework that would allow a more precise identification of the role of motivated reasoning in such opinions. Finally, we conclude by providing examples from completed and planned studies that apply this framework. Ultimately, we hope to give scholars and practitioners better tools to isolate why people hold the climate opinions they do and to develop effective communication strategies to change those opinions.

Recent work in psychology on ‘cultural cognition’ suggests that our cultural background drives our attitudes towards a range of politically contentious issues in science such as global warming. This work is part of a more general attempt to investigate the ways in which our wants, wishes and desires impact on our assessments of information, events and theories. Put crudely, the idea is that we conform our assessments of the evidence for and against scientific theories with clear political relevance to our (...) pre-existing political beliefs and convictions. In this paper I explore the epistemological consequences of cultural cognition. What does it mean for the rationality of our beliefs about issues such as global warming? I argue for an unsettling conclusion. Not only are those on the ‘political right’ who reject the scientific consensus on issues like global warming unjustified in doing so, some of those on the ‘political left’ who accept the consensus are also unjustified in doing so. I finish by addressing the practical implications of my conclusions. (shrink)

Why does performing certain tasks cause the aversive experience of mental effort and concomitant deterioration in task performance? One explanation posits a physical resource that is depleted over time. We propose an alternative explanation that centers on mental representations of the costs and benefits associated with task performance. Specifically, certain computational mechanisms, especially those associated with executive function, can be deployed for only a limited number of simultaneous tasks at any given moment. Consequently, the deployment of these computational mechanisms carries (...) an opportunity cost – that is, the next-best use to which these systems might be put. We argue that the phenomenology of effort can be understood as the felt output of these cost/benefit computations. In turn, the subjective experience of effort motivates reduced deployment of these computational mechanisms in the service of the present task. These opportunity cost representations, then, together with other cost/benefit calculations, determine effort expended and, everything else equal, result in performance reductions. In making our case for this position, we review alternative explanations for both the phenomenology of effort associated with these tasks and for performance reductions over time. Likewise, we review the broad range of relevant empirical results from across sub-disciplines, especially psychology and neuroscience. We hope that our proposal will help to build links among the diverse fields that have been addressing similar questions from different perspectives, and we emphasize ways in which alternative models might be empirically distinguished.

I propose a new approach to the constitutive problem of psychology ‘what is mind?’ The first section introduces modifications of the received scope, methodology, and evaluation criteria of unified theories of cognition in accordance with the requirements of evolutionary compatibility and of a mature science. The second section outlines the proposed theory. Its first part provides empirically verifiable conditions delineating the class of meaningful neural formations and modifies accordingly the traditional conceptions of meaning, concept and thinking. This analysis is part (...) of a theory of communication in terms of inter-level systems of primitives that proposes the communication-understanding principle as a psychological invariance. It unifies a substantial amount of research by systematizing the notions of meaning, thinking, concept, belief, communication, and understanding and leads to a minimum vocabulary for this core system of mental phenomena. Its second part argues that written human language is the key characteristic of the artificially natural human mind. Overall, the theory both supports Darwin’s continuity hypothesis and proposes that the mental gap is within our own species. (shrink)
