Graded Causation and Defaults
  Recent work in psychology and experimental philosophy has shown that
judgments of actual causation are often influenced by consideration of
defaults, typicality, and normality. A number of philosophers and computer
scientists have also suggested that an appeal to such factors can help deal
with problems facing existing accounts of actual causation. This paper develops
a flexible formal framework for incorporating defaults, typicality, and
normality into an account of actual causation. The resulting account takes
actual causation to be both graded and comparative. We then show how our
account would handle a number of standard cases.
