The sure thing principle,dilations, and objective probabilities

The common theme that unites the four sections is STP, the sure thing principle. But the paper can be divided neatly into two parts. The first, consisting of the first two sections, contains an analysis of STP as it figures in Savage?s system and proposals of changes to that system. Also possibilities for partially ordered acts are considered. The second, consisting of the last two sections, is about imprecise probabilities, dilations and objective probabilities. Variants of STP are considered but this part is self-contained and can be read separately. The main claim there is that dilations, which can have extremely counterintuitive consequences, can be eliminated by a more careful analysis of the phenomenon. It outlines a proposal of how to do it. Here the concept of objective probabilities plays a crucial role.     

What causes failure to apply the Pigeonhole Principle in simple reasoning problems?

The Pigeonhole Principle states that if n items are sorted into m categories and if n > m, then at least one category must contain more than one item. For instance, if 22 pigeons are put into 17 pigeonholes, at least one pigeonhole must contain more than one pigeon. This principle seems intuitive, yet when told about a city with 220,000 inhabitants none of whom has more than 170,000 hairs on their head, many people think that it is merely likely that two inhabitants have the exact same number of hair. This failure to apply the Pigeonhole Principle might be due to the large numbers used, or to the cardinal rather than nominal presentation of these numbers. We show that performance improved both when the numbers are presented nominally, and when they are small, albeit less so. We discuss potential interpretations of these results in terms of intuition and reasoning.     

Principal Component Analysis of the College Date Rape Attitude Survey (CDRAS)

ABSTRACT

The College Date Rape Attitude Survey (CDRAS), a measure intended to assess attitudes related to risk for committing rape in adolescents and young adults, was examined to determine the principal component structure of rape-related attitudes in data collected on an undergraduate college sample. Results provide evidence that responses to the instrument are reliable with regard to internal consistency, and that the CDRAS measures four rape-related attitudes: Entitlement, Blame Shifting, Traditional Roles, and Overwhelming Sexual Arousal. The CDRAS could be used to elicit information about student's attitudes, which could then be used to develop, implement, and evaluate an intervention specific to the needs of that population.     

Privileged, Typical, or not even that? – Our Place in the World According to the Copernican and the Cosmological Principles

Summary  If we are to constrain our place in the world, two principles are often appealed to in science. According to the Copernican Principle, we do not occupy a privileged position within the Universe. The Cosmological Principle, on the other hand, says that our observations would roughly be the same, if we were located at any other place in the Universe. In our paper we analyze these principles from a logical and philosophical point of view. We show how they are related, how they can be supported and what use is made of them. Our main results are: 1. There is a logical gap between both principles insofar as the Cosmological Principle is significantly stronger than the Copernican Principle. 2. A step that is often taken for establishing the Cosmological Principle on the base of the Copernican Principle and observations is not incontestable as it stands, but can be supplemented with a different argument. 3. The Cosmological Principle might be crucial for cosmology to the extent it is not supported by empirical evidence.     

Freedom, Responsibility, and Agency

This paper first distinguishes three alternative views that adherents to both incompatibilism and PAP may take as to what constitutes an agent's determining or controlling her action (if it's not the action's being deterministically caused by antecedent events): the indeterministic-causation view, the agent-causation view, and "simple indeterminism." The bulk of the paper focusses on the dispute between simple indeterminism - the view that the occurrence of a simple mental event is determined by its subject if it possesses the "actish" phenomenal quality and is undetermined by antecedent events - and Timothy O'Connor's agent-causation view. It defends simple indeterminism against O'Connor's objections to it and offers objections to O'Connor's view.     

The absolutism problem in On Liberty

Mill argues that, apart from the principle of utility, his utilitarianism is incompatible with absolutes. Yet in On Liberty he introduces an exceptionless anti-paternalism principle—his liberty principle. In this paper I address ‘the absolutism problem,’ that is, whether Mill's utilitarianism can accommodate an exceptionless principle. Mill's absolute claim is not a mere bit of rhetoric. But the four main solutions to the absolutism problem are also not supported by the relevant texts. I defend a fifth solution—the competence view—that turns on his attention to decision-making structures and, in particular, on the role of expertise considerations in his account.
