The papers collected here are, with three exceptions, those presented at
a conference on probability and causation held at the University of
California at Irvine on July 15-19, 1985. The exceptions are that David
Freedman and Abner Shimony were not able to contribute the papers that
they presented to this volume, and that Clark Glymour who was not able
to attend the conference did contribute a paper. We would like to thank
the National Science Foundation and the School of Humanities of the
University of California at Irvine for generous support. WILLIAM HARPER

Irvine Vll INTRODUCTION PART I: DECISIONS AND GAMES Causal notions have
recently corne to figure prominently in discussions about rational
decision making. Indeed, a relatively influential new approach to
theorizing about rational choice has come to be called "causal decision
theory". 1 Decision problems such as Newcombe's Problem and some
versions of the Prisoner's Dilemma where an act counts as evidence for a
desired state even though the agent knows his choice of that act cannot
causally influence whether or not the state obtains have motivated
causal decision theorists.
