Anger in Wikipedia: Perceived intentionality and threat appraisal as mediators of anger about man‐made attacks

The online encyclopedia Wikipedia has established strict guidelines for the objectivity of content. At the same time, Wikipedia includes articles on negative events, such as disasters or man‐made attacks. These events can elicit strong emotions, which in turn may spill over into Wikipedia articles. Previous research has shown that Wikipedia articles on man‐made attacks contain more anger‐related content than Wikipedia articles on disasters. Building on these findings, we aimed to investigate whether the threat that Wikipedia authors experience when they learn of an attack is relevant as a factor in explaining the anger effect. Threat is known to elicit active and engaged reactions, such as anger, which is why it is a likely explaining factor. Our research also aimed to replicate the findings from the linguistic analysis of the Wikipedia articles using controlled scenario‐based laboratory experiments. Three studies demonstrated that man‐made attacks (terrorist attack, shooting rampage) elicited more threat, more anger, and more expressions of anger‐related content in Wikipedia texts than nature‐made disasters (earthquake, flood) and man‐made disasters (train accident). Moreover, threat was relevant as a factor in explaining the effects on anger and anger‐related content in the Wikipedia texts. These mediations could be explained by the perceived intentionality of the event. This research highlights the findings that perceived intentionality and threat are relevant mediating factors for feelings and expressions of anger after man‐made attacks.     

Lax monitoring versus logical intuition: The determinants of confidence in conjunction fallacy

The general assumption that people fail to notice discrepancy between their answer and the normative answer in the conjunction fallacy task has been challenged by the theory of Logical Intuition. This theory suggests that people can detect the conflict between the heuristic and normative answers even if they do not always manage to inhibit their intuitive choice. This theory gained support from the finding that people report lower levels of confidence in their choice after they commit the conjunction fallacy compared to when their answer is not in conflict with logic. In four experiments we asked the participants to give probability estimations to the options of the conflict and no-conflict versions of the tasks in the original set-up of the experiment or in a three-option design. We found that participants perceive probabilities for the options of the conflict version less similar than for the no-conflict version. As people are less confident when choosing between more similar options, this similarity difference is proposed to serve as a mediator in the task in a way that the conflict and no-conflict conditions have their effects on confidence ratings through manipulating the similarity of the answer options.     

Genes and Citizens: Can Moral Philosophy Learn from Evolutionary Biology?

The claim that moral philosophers have something to learn from recent neo-Darwinian theory cannot be sustained – at least, not in the case of the three theses characteristic of the latter on which I concentrate. The first thesis, reductionism, is open to some serious, and familiar, objections. Neo-Darwinism can escape those objections only by weakening its position to a point at which it can no longer be described as distinctively reductionist. The second, atavism, mistakenly attempts to generalise from the apparent persistence of` ‘vestigial’ behaviour patterns. Third, neo-Darwinists are frequently guilty of a number of confusions over the relation between fact and value. In conclusion, I point out that neo-Darwinism derives a certain ideological dynamic from the misleading supposition that patterns of explanation which succeed in one area necessarily apply in others.

Linda问题：“齐当别”抉择模型的解释

大量有关人类归因判断的研究表明,人类经常违反理性概率公理。Tversky和Kahneman（1983）使用Linda问题等特定场景的研究发现,人们系统性地表现出违反理性推断标准,判断合取事件发生概率大于其组成事件发生概率,称之为合取谬误,并用人们使用代表性启发式判断概率来解释该现象产生的原因。然而使用启发式观点对合取谬误现象进行解释过于模糊不清。该文首先介绍了合取谬误现象及其解释模型,然后应用Li（1994,2004）提出的不确定情形下决策理论——“齐当别”抉择模型对Linda问题中合取谬误产生的原因进行了新的解释     

Emerging Infectious Diseases: Coping with Uncertainty

The world’s scientific community must be in a state of constant readiness to address the threat posed by newly emerging infectious diseases. Whether the disease in question is SARS in humans or BSE in animals, scientists must be able to put into action various disease containment measures when everything from the causative pathogen to route(s) of transmission is essentially uncertain. A robust epistemic framework, which will inform decision-making, is required under such conditions of uncertainty. I will argue that this framework should have reasoning at its center and, specifically, that forms of reasoning beyond deduction and induction should be countenanced by scientists who are confronted with emerging infectious diseases. In previous articles, I have presented a case for treating certain so-called traditional informal fallacies as rationally acceptable forms of argument that can facilitate scientific inquiry when little is known about an emerging disease. In this article, I want to extend that analysis by highlighting the unique features of these arguments that makes them specially adapted to cope with conditions of uncertainty. Of course, such a view of the informal fallacies must at least be consistent with the reasoning practices of scientists, and particularly those scientists (viz. epidemiologists) whose task it is to track and respond to newly emerging infectious diseases. To this end, I draw upon examples of scientific reasoning from the UK’s BSE crisis, a crisis that posed a significant threat to both human and animal health.

Naturalizing Ethics: the Biology and Psychology of Moral Agency

Moral agency is a central feature of both religious and secular conceptions of human beings. In this paper I outline a scientific naturalistic model of moral agency making use of current findings and theories in sociobiology,developmental psychology, and social cognitive theory. The model provides answers to four central questions about moral agency: (1) what it is, (2) how it is acquired, (3) how it is put to work, and (4) how it is justified. I suggest that this model can provide religious and secular moral theories with a basis for a common understanding of moral agency.     

Causal conjunction fallacies: The roles of causal strength and mental resources

In two experiments we tested the prediction derived from Tversky and Kahneman's (1983) work on the causal conjunction fallacy that the strength of the causal connection between constituent events directly affects the magnitude of the causal conjunction fallacy. We also explored whether any effects of perceived causal strength were due to graded output from heuristic Type 1 reasoning processes or the result of analytic Type 2 reasoning processes. As predicted, Experiment 1 demonstrated that fallacy rates were higher for strongly than for weakly related conjunctions. Weakly related conjunctions in turn attracted higher rates of fallacious responding than did unrelated conjunctions. Experiment 2 showed that a concurrent memory load increased rates of fallacious responding for strongly related but not for weakly related conjunctions. We interpret these results as showing that manipulations of the strength of the perceived causal relationship between the conjuncts result in graded output from heuristic reasoning process and that additional mental resources are required to suppress strong heuristic output.
