 Rott (2011) defends Gärdenfors’s Ramsey test by showing that it does not create a specific problem for the Preservation Principle. Its consequence is rather that both preservation of factual beliefs and preservation of flat conditionals entail that there is no preservation of right-nested conditionals of depth 2. GRT allows for right-nested conditionals if a model for iterated belief revision is available (other compounds of conditionals are more difficult to make sense of). It can be shown, for instance, that supposing there is an atom \(p\) on which the believer suspends judgment, the conditional
