Democracy and the Common Good: A Study of the Weighted Majority Rule

In this study I analyse the performance of a democratic decision-making rule: the weighted majority rule. It assigns to each voter a number of votes that is proportional to her stakes in the decision. It has been shown that, for collective decisions with two options, the weighted majority rule in combination with self-interested voters maximises the common good when the latter is understood in terms of either the sum-total or prioritarian sum of the voters’ well-being. The main result of my study is that this argument for the weighted majority rule — that it maximises the common good — can be improved along the following three main lines. (1) The argument can be adapted to other criteria of the common good, such as sufficientarian, maximin, leximin or non-welfarist criteria. I propose a generic argument for the collective optimality of the weighted majority rule that works for all of these criteria. (2) The assumption of self-interested voters can be relaxed. First, common-interest voters can be accommodated. Second, even if voters are less than fully competent in judging their self-interest or the common interest, the weighted majority rule is weakly collectively optimal, that is, it almost certainly maximises the common good given large numbers of voters. Third, even for smaller groups of voters, the weighted majority rule still has some attractive features. (3) The scope of the argument can be extended to decisions with more than two options. I state the conditions under which the weighted majority rule maximises the common good even in multi-option contexts. I also analyse the possibility and the detrimental effects of strategic voting. Furthermore, I argue that self-interested voters have reason to accept the weighted majority rule

Harm and Discrimination

Many legal, social, and medical theorists and practitioners, as well as lay people, seem to be concerned with the harmfulness of discriminative practices. However, the philosophical literature on the moral wrongness of discrimination, with a few exceptions, does not focus on harm. In this paper, I examine, and improve, a recent account of wrongful discrimination, which divides into (1) a definition of group discrimination, and (2) a characterisation of its moral wrong-making feature in terms of harm. The resulting account analyses the wrongness of discrimination in terms of intrapersonal comparisons of the discriminatee's actual, and relevantly counterfactual, well-being levels. I show that the account faces problems from counterfactuals, which can be traced back specifically to the orthodox - comparative, counterfactual, welfarist concept of harm. I argue that non-counterfactual and non-comparative harm concepts face problems of their own, and don't fit easily with our best understanding of discrimination; hence they are unsuitable to replace the orthodox concept here. I then propose a non-orthodox comparative, counterfactual, hybrid (partly welfarist, partly non-welfarist) - concept of harm, which relies on counterfactual comparisons of ways of being treated (rather than well-being levels). I suggest how such a concept can help us handle the problems from counterfactuals, at least for my account of discrimination. I also show that there are similar proposals in other harmrelated debates. An upshot of the paper is thus to corroborate the case for a non-orthodox, hybrid concept of harm, which seems better able to fulfil its functional roles in a variety of contexts

Should the probabilities count?

When facing a choice between saving one person and saving many, some people have argued that fairness requires us to decide without aggregating numbers; rather we should decide by coin toss or some form of lottery, or alternatively we should straightforwardly save the greater number but justify this in a non-aggregating contractualist way. This paper expands the debate beyond well-known number cases to previously under-considered probability cases, in which not (only) the numbers of people, but (also) the probabilities of success for saving people vary. It is shown that, in these latter cases, both the coin toss and the lottery lead to what is called an awkward conclusion, which makes probabilities count in a problematic way. Attempts to avoid this conclusion are shown to lead into difficulties as well. Finally, it is shown that while the greater number method cannot be justified on contractualist grounds for probability cases, it may be replaced by another decision method which is so justified. This decision method is extensionally equivalent to maximising expected value and seems to be the least problematic way of dealing with probability cases in a non-aggregating manner.AuthorCount:1;</p

Asymmetry and Non-Identity

In this article we distinguish two versions of the non-identity problem: one involving positive well-being and one involving negative well-being. Intuitively, there seems to be a difference between the two versions of the problem. In the negative case it is clear that one ought to cause the better-off person to exist. However, it has recently been suggested that this is not so in the positive case. We argue that such an asymmetrical treatment of the two versions should be rejected and that this is evidence against views according to which it is permissible to cause the less well-off person to exist in the positive non-identity case
