This book describes an original, empirical study of judicial decision
making. The process of determining sentences is a difficult one for
judges and often unnecessarily intuitive, subjective, and complex. The
present study introduces a conceptual outline and empirical technique
for increasing the precision of sentencing policy, thus offering an aid
to judges who sentence in the light of this policy. The primary purpose
of this model of judicial decision making is to provide a framework for
scaling the seriousness of any single case in relation to the facts of
that case and for relating this assessment to the appropriate quantum of
sentence. The validity of the model is tested and cross-validated in an
archival study. This innovative research serves as an important
prototype for a system of numerical guidance to judges and sentencers.
