Fienberg convincingly demonstrates that Bayesian models and methods represent
a powerful approach to squeezing illumination from data in public policy
settings. However, no school of inference is without its weaknesses, and, in
the face of the ambiguities, uncertainties, and poorly posed questions of the
real world, perhaps we should not expect to find a formally correct inferential
strategy which can be universally applied, whatever the nature of the question:
we should not expect to be able to identify a "norm" approach.
