 John Broome (2000: 85) offers a closely related objection, which nevertheless deserves separate mention. Broome observes that any proposition trivially entails itself. From  IMP  it thus follows that I ought to believe any proposition I in fact believe. But this seems patently false: I might hold any number of irresponsibly acquired beliefs. The fact that, by mere happenstance, I hold these beliefs, in no way implies that I ought to believe them. Call this variation of the Objection from Belief Revision, the Bootstrapping Objection.
