The Logic of Team Reasoning
Robert Sugden · Palgrave Macmillan UK eBooks · 2005
Almost all decision theory presupposes that agency is invested in individuals . Each individual is represented as making decisions in the light of his or her own preferences and beliefs. A person may have preferences about consequences of her actions which affect other people; but these are still her preferences. She may have beliefs about what other people will choose; but these are still her beliefs. In making decisions, she acts alone.
