This book has argued that a traditional Bayesian framework using Conditionalization as its updating constraint cannot adequately model stories involving memory loss and context-sensitivity, because of the rational loss of certainties in such stories. The book has advocated a new modeling framework, the Certainty-Loss Framework (CLF), as a replacement. This chapter first explains why the rational requirements in stories involving memory loss and context-sensitivity cannot be settled by Dutch Book arguments. Next the chapter explains why the difficulties traditional Bayesian frameworks have with certainty loss could not have been solved by moving to a framework based on Jeffrey Conditionalization. Finally, the chapter explains why cases involving certainty loss due to the acquisition of evidential defeaters are not best modeled using CLF.
