Decision theory applied to rare events

The decision theory that is more or less dedicated to reinforce the basis of classical statistics, seems to have reached an opposite results, strongly justifying Bayesian methods. This may lead to remove reserves to the use of probabilistic and 'statistic' methods in the case of rare events. However, a thorough examination of the theory's concepts and axioms leads to requirements that may be difficult to satisfy in the framework of the definition itself of rare events. A collective effort to respond to these requirements would be extremely desirable; it could contribute to enhance the present situation through a better consensus on risk assessment
