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.

Validity and Necessity

In this paper I argue against the commonly received view that Kripke’s formal Possible World Semantics (PWS) reflects the adoption of a metaphysical interpretation of the modal operators. I consider in detail Kripke’s three main innovations vis-à-vis Carnap’s PWS: a new view of the worlds, variable domains of quantification, and the adoption of a notion of universal validity. I argue that all these changes are driven by the natural technical development of the model theory and its related notion of validity: they are dictated by merely formal considerations, not interpretive concerns. I conclude that Kripke’s model theoretic semantics does not induce a metaphysical reading of necessity, and is formally adequate independently of the specific interpretation of the modal operators.     

Catching the liar as a matter of justice: Effects of belief in a just world on deception detection accuracy and the moderating role of mortality salience

Belief in a just world has been linked to high interpersonal trust and less suspicion of deception. We therefore predicted people with a strong dispositional belief in a just world to have low motivation to accurately detect deception. Accordingly, we hypothesized such a belief to be negatively related to accuracy in deception detection. Furthermore, research on Terror Management Theory has indicated that culturally shared values, such as justice, become more important after mortality salience. Thus, we assumed engaging in justice concerns after a death threat is especially relevant for people with a strong belief in a just world, and further, that accurate deception detection is a matter of justice. Based on this reasoning, we expected people with a strong belief in a just world to have an increased motivation to accurately detect deception after mortality salience. Consequently, we hypothesized dispositional differences in belief in a just world to be unrelated to accuracy in deception detection after mortality salience. In line with these predictions, our study revealed that participants with a strong (vs. weak) belief in a just world were worse in deception detection unless they had first been reminded of their mortality.     

Long-term focus and prosocial–antisocial tendencies interact to predict belief in just world

According to justice motive theory, individuals need to believe that the world is a just place where people generally get what they deserve (Lerner, 1977). Individuals are thought to need belief in a just world (BJW) in part because it gives them the confidence required to invest in long-term goals. However, BJW can only provide confidence that individuals will reap the rewards of their investments if they invest in their goals through prosocial means (e.g., Hafer, 2000). The current study provides evidence for this argument. Specifically, we examined individual differences in BJW, long-term goal focus, and prosocial–antisocial tendencies to test the hypothesis that higher long-term focus would be associated with higher BJW, but only amongst those who are also high in prosocial (low in antisocial) tendencies. This hypothesis was tested four times using four measures of prosocial–antisocial tendencies. Simple slopes analyses revealed the predicted pattern of results for three of the four measures. Our findings (a) provide novel support for the idea that BJW aids in the prosocial pursuit of long-term goals, and (b) have implications for individual variation in BJW.     

Anticipation in Real‐World Scenes: The Role of Visual Context and Visual Memory

The human sentence processor is able to make rapid predictions about upcoming linguistic input. For example, upon hearing the verb eat, anticipatory eye‐movements are launched toward edible objects in a visual scene (Altmann & Kamide, 1999). However, the cognitive mechanisms that underlie anticipation remain to be elucidated in ecologically valid contexts. Previous research has, in fact, mainly used clip‐art scenes and object arrays, raising the possibility that anticipatory eye‐movements are limited to displays containing a small number of objects in a visually impoverished context. In Experiment 1, we confirm that anticipation effects occur in real‐world scenes and investigate the mechanisms that underlie such anticipation. In particular, we demonstrate that real‐world scenes provide contextual information that anticipation can draw on: When the target object is not present in the scene, participants infer and fixate regions that are contextually appropriate (e.g., a table upon hearing eat). Experiment 2 investigates whether such contextual inference requires the co‐presence of the scene, or whether memory representations can be utilized instead. The same real‐world scenes as in Experiment 1 are presented to participants, but the scene disappears before the sentence is heard. We find that anticipation occurs even when the screen is blank, including when contextual inference is required. We conclude that anticipatory language processing is able to draw upon global scene representations (such as scene type) to make contextual inferences. These findings are compatible with theories assuming contextual guidance, but posit a challenge for theories assuming object‐based visual indices.     

The Meaning of ＂Existence＂ and the Contingency of Sense

In this paper I argue first for a revisionary ontology, that is, for an understanding of ＂existence＂ as the property of a field not to be empty. In this context, I distinguish between ＂metaphysics＂ （the theory of totality or of fundamental reality） and ＂ontology＂ （the systematic investigation into the meaning of ＂existence＂）. In the second part, I provide a sketch for a corresponding revisionary theory of the modalities in light of the new ontology proposed.     

Unfairness begets unfairness: Victim derogation bias in employee ratings

This research investigated criterion contamination in human resource evaluations, specifically victim derogation in which third parties (e.g., managers, co-workers) systematically undervalue the performance and potential of individuals who have previously suffered organizational injustices. A policy capturing design (Study 1) found that managers rated job applicants who had been treated unfairly by their previous employers as less suitable than fairly treated applicants, after objective performance information was controlled. In Study 2, the effect of unfair treatment on job applicant ratings was found to be moderated by managers’ just world beliefs, with applicant ratings reflecting more derogation among managers with higher (vs. lower) Belief in a Just World. In Study 3, the pattern of results from Study 2 was replicated in a performance evaluation context using peers as raters. Moreover, in Study 3 an intervention that activated raters’ moral identity was found to attenuate victim derogation bias.     

父母情感温暖对青少年感恩的影响:责任心与公正世界信念的中介作用

以748名高中生为被试,采用问卷法考察父母情感温暖、责任心以及公正世界信念对青少年感恩的影响机制。结果显示：（1）高中生的父母情感温暖可显著正向预测其感恩;（2）在控制了性别、年龄以及年级后,父母情感温暖可分别通过责任心和公正世界信念间接地影响青少年的感恩。这表明责任心和公正世界信念是父母情感温暖影响青少年感恩的重要中介变量。     

World‐Pictures and Wittgensteinian Certainty

Although certainty is a fundamental notion in epistemology, it is less studied in contemporary analytic epistemology than other important notions such as knowledge or justification. This paper focuses on Wittgensteinian certainty, according to which the very basic dimension of our epistemic practices, the elements of our world‐pictures, are objectively certain, in that we cannot legitimately doubt them. The aim of the paper is to offer the best philosophical way to clarify Wittgensteinian certainty, in a way that is consonant with Wittgenstein's fundamental insights. The paper critiques two alternative proposals for clarifying Wittgensteinian certainty that are philosophically unsatisfying: the rule view and the proposition view. Finally, it instead shows how viewing world‐pictures as pictures, in the sense of unclear conceptions, is a more philosophically fruitful approach to understanding world‐pictures.     

青少年公正世界信念对抑郁的影响:感恩和自尊的序列中介作用

为探讨青少年公正世界信念与抑郁的关系,以及感恩和自尊在二者关系中的作用机制,采用公正世界信念问卷(BJW)、感恩问卷(GQ-6)、自尊量表(SES)和流调中心用抑郁量表(CES-D)对1049名高中学生进行调查。结果发现:(1)青少年公正世界信念、感恩和自尊两两之间呈显著正相关,且三者均与抑郁呈显著负相关。(2)青少年公正世界信念通过感恩和自尊的中介作用对抑郁产生影响,且该中介效应包含了三条中介路径——感恩的简单中介效应,自尊的简单中介效应,以及感恩→自尊的链式中介作用。研究结果揭示了青少年公正世界信念对抑郁产生影响的内部心理机制,为引导青少年更好地利用公正世界信念提升感恩和自尊的水平以及更好地促进心理健康发展提供了有益建议。
