Bayesian Synthesis or Likelihood Synthesis - What Does the Borel Paradox Say?

The relevance of the Borel paradox to Bayesian Synthesis is explained and illustrated by examples related to the assessment of bowhead whales. It is argued that the paradox is a serious, and that if conditions for the paradox to be of minor concern are observed, the attraction of the Bayesian Synthesis method will fade, sine then the freedom of disregarding the constraints of the deterministic model when carrying out the initial statistical analysis is destroyed.
