The purpose of this note is to give counterexamples to the containment $I^{(3)}\subset I^2$ over the real numbers.

In this extended abstract, we carefully examine a purported counterexample to a postulate of iterated belief revision. We suggest that the example is better seen as a failure to apply the theory of belief revision in sufficient detail. The…
