RE‐ENVISIONING HOPE: ANTHROPOGENIC CLIMATE CHANGE,LEARNED IGNORANCE,AND RELIGIOUS NATURALISM

In this essay, I introduce religious naturalism as one contemporary religious response to anthropogenic climate change; in so doing, I offer a concept of hope associated with the beauty of ignorance, of not knowing ourselves in the usual manner. Reframing humans as natural processes in relationship with other forms of nature, religious naturalism encourages humans’ processes of transformative engagement with each other and with the more‐than‐human worlds that constitute our existence. Hope in this context is anticipating what possibilities may occur when human organisms enact our evolutionary capacities as relational organisms who can love, engaging in multilayered processes of changing behaviors, values, and relationships that promote the betterment of myriad nature.     

Ignorance,Information and Autonomy

People have a powerful interest in geneticprivacy and its associated claim to ignorance,and some equally powerful desires to beshielded from disturbing information are oftenvoiced. We argue, however, that there is nosuch thing as a right to remain in ignorance,where a right is understood as an entitlementthat trumps competing claims. This doesnot of course mean that information must alwaysbe forced upon unwilling recipients, only thatthere is no prima facie entitlement to beprotected from true or honest information aboutoneself. Any claims to be shielded frominformation about the self must compete onequal terms with claims based in the rights andinterests of others. In balancing the weightand importance of rival considerations aboutgiving or withholding information, if rightsclaims have any place, rights are more likelyto be defensible on the side of honestcommunication of information rather than indefence of ignorance. The right to free speechand the right to decline to acceptresponsibility to take decisions for othersimposed by those others seem to us moreplausible candidates for fully fledged rightsin this field than any purported right toignorance. Finally, and most importantly, ifthe right to autonomy is invoked, a properunderstanding of the distinction between claimsto liberty and claims to autonomy show that theprinciple of autonomy, as it is understood incontemporary social ethics and English law,supports the giving rather than the withholdingof information in most circumstances.     

行为决策中模糊规避研究的回顾与展望

模糊规避是指在相同奖赏的情况下,决策者会偏好有精确概率的事件而不是从主观上判断具有相同模糊概率的事件。自从Ellsberg提出模糊规避的概念以来,模糊规避已在行为决策研究的多个领域得到广泛验证。本文梳理了近五十年来关于模糊规避的研究文献,系统分析了模糊规避的研究范式、心理机制和影响因素,同时提出了未来的研究展望。     

Gender Bias and Pluralistic Ignorance in Perceptions of Fitness Assessments

Two studies examined the relationship between cadets' views toward women, specifically, attitudes about fitness testing at the United States Air Force Academy (USAFA). Cadets completed measures of views toward women in society, in the military, at USAFA, and fitness testing. Results revealed that many male cadets held sexist attitudes of women in all categories. Cadets who held egalitarian views of women in society and in the military were more likely to support equitable fitness standards. Furthermore, cadets' personal viewpoints differed from their perception of the entire cadet population viewpoint, creating an environment of pluralistic ignorance. That is, cadets believed the collective was more sexist than themselves, suggesting that a vocal minority who perpetuate sexist attitudes may hinder changes in culture.     

Moral responsibility and the ‘ignorant scientist’

The question whether a scientist can be responsible for an outcome of her work which she does not foresee, and so is ignorant of, is addressed. It is argued that ignorance can be a ground for the attribution of responsibility, on condition that there are general principles, rules or norms, that the subject should be aware of. It is maintained that there are such rules which inform the practice of science as a social institution.     

Twelve-month-olds communicate helpfully and appropriately for knowledgeable and ignorant partners

In the current study we investigated whether 12-month-old infants gesture appropriately for knowledgeable versus ignorant partners, in order to provide them with needed information. In two experiments we found that in response to a searching adult, 12-month-olds pointed more often to an object whose location the adult did not know and thus needed information to find (she had not seen it fall down just previously) than to an object whose location she knew and thus did not need information to find (she had watched it fall down just previously). These results demonstrate that, in contrast to classic views of infant communication, infants' early pointing at 12 months is already premised on an understanding of others' knowledge and ignorance, along with a prosocial motive to help others by providing needed information.     

The Burden of Proof and Its Role in Argumentation

The notion of “the burden of proof” plays an important role in real-world argumentation contexts, in particular in law. It has also been given a central role in normative accounts of argumentation, and has been used to explain a range of classic argumentation fallacies. We argue that in law the goal is to make practical decisions whereas in critical discussion the goal is frequently simply to increase or decrease degree of belief in a proposition. In the latter case, it is not necessarily important whether that degree of belief exceeds a particular threshold (e.g., ‘reasonable doubt’). We explore the consequences of this distinction for the role that the “burden of proof” has played in argumentation and in theories of fallacy.     

Rules for Reasoning from Knowledge and Lack of Knowledge

In this paper, the traditional view that argumentum ad ignorantiam is a logical fallacy is challenged, and lessons are drawn on how to model inferences drawn from knowledge in combination with ones drawn from lack of knowledge. Five defeasible rules for evaluating knowledge-based arguments that apply to inferences drawn under conditions of lack of knowledge are formulated. They are the veridicality rule, the consistency of knowledge rule, the closure of knowledge rule, the rule of refutation and the rule for argument from ignorance. The basic thesis of the paper is that knowledge-based arguments, including the argument from ignorance, need to be evaluated by criteria for epistemic closure and other evidential rules that are pragmatic in nature, that need to be formulated and applied differently at different stages of an investigation or discussion. The paper helps us to understand practical criteria that should be used to evaluate all arguments based on knowledge and/or ignorance.

Biases in the perceived prevalence and motives of severe acute respiratory syndrome prevention behaviors among Chinese high school students in Hong Kong

In two studies conducted in Hong Kong during and immediately after the outbreak of severe acute respiratory syndrome (SARS), participants displayed several social cognitive biases when they estimated the prevalence of and inferred the motives underlying SARS preventive behaviors. First, participants who practiced preventive behaviors (practicers) consistently estimated that more people practiced such behaviors than did non-practicers (false consensus bias). Second, for some preventive behaviors, participants believed that their own behaviors were more motivated by prosocial concerns (relative to self-interest) than were other practicers (pluralistic ignorance). Finally, non-practicers underestimated the importance of prosocial concerns underlying some preventive behaviors (actor-observer bias). We discussed the relevance of these social cognitive biases to health education and to Hong Kong people's psychological reactions to SARS.
