This paper reviews applications in computer science that decision
theorists have addressed for years, discusses the requirements posed
by these applications that place great strain on decision
theory/social science methods, and explores applications in the social
and decision sciences of newer decision-theoretic methods developed
with computer science applications in mind. The paper deals with the
relation between computer science and decision-theoretic methods of
consensus, with the relation between computer science and game theory
and decisions, and with ``algorithmic decision theory.''
