The chapter reviews recent theoretical and empirical developments concerning the theory of team reasoning in game theoretic interactions.

Normative discourse on genocide frequently refers to group injuries, but this can be problematic for those for whom normative justification ought, in principle, to be reducible to individual terms. Such ethical individualists may hold that an ultimately individualizable description of injury is always theoretically superior (in lacking either superfluous or ontologically suspect entities). Accepting the strictures of individualistic justification, this paper presumes that attributing injury to group subjects will be unsatisfying if this attribution does not include a normatively significant group (...) character. Taking up these challenges, this essay analyzes the conceptual possibility of normatively significant group injury, describing its necessary and sufficient conditions. (shrink)

More than one person can be responsible for a particular state of affairs--In this sense collective moral responsibility does indeed exist. However, Even in such cases, Moral responsibility is still fundamentally individualized since each agent responsible for a particular state of affairs is responsible for his/her actions which have the intention of producing this state of affairs.

The basic bearer of responsibility is individuals, because that isall there are – nothing else can literally be the bearer of fullresponsibility. Claims about group responsibility therefore needanalysis. This would be impossible if all actions must be understoodas ones that could be performed whether or not anyone else exists.Individuals often act by virtue of membership in certain groups;often such membership bears a causal role in our behavior, andsometimes people act deliberately in order to promote the prospectsof members of a given (...) group. Nevertheless, it is rational to awardproportionally to individual contributions to those actions andindividual shares in the production of the consequences of thoseactions. (shrink)

This paper offers a comparison of three different kinds of collective attitudes: aggregate, common, and corporate attitudes. They differ not only in their relationship to individual attitudes—e.g., whether they are “reducible” to individual attitudes—but also in the roles they play in relation to the collectives to which they are ascribed. The failure to distinguish them can lead to confusion, in informal talk as well as in the social sciences. So, the paper’s message is an appeal for disambiguation.

In this paper, I provide the framework for an account of group assertion. On my view, there are two kinds of group assertion, coordinated and authority-based, with authority-based group assertion being the core notion. I argue against a deflationary view, according to which a group’s asserting is understood in terms of individual assertions, by showing that a group can assert a proposition even when no individual does. Instead, I argue on behalf of an inflationary view, according to which it is (...) the group itself that asserts, a conclusion supported by the fact that paradigmatic features of assertion apply only at the level of the group. A central virtue of my account is that it appreciates the important relationship that exists between most groups and their spokespersons, as well as the consequences that follow from this relationship. My view, thus, provides the framework for distinguishing when responsibility for an assertion lies at the collective level, and when it should be shouldered by an individual simply speaking for herself.

If I were asked to put forward an ethical principle which I considered to be especially certain, it would be that no one can be responsible, in the properly ethical sense, for the conduct of another. Responsibility belongs essentially to the individual. The implications of this principle are much more far-reaching than is evident at first, and reflection upon them may lead many to withdraw the assent which they might otherwise be very ready to accord to this view of responsibility. (...) But if the difficulties do appear to be insurmountable, and that, very certainly, does not seem to me to be the case, then the proper procedure will be, not to revert to the barbarous notion of collective or group responsibility, but to give up altogether the view that we are accountable in any distinctively moral sense.
