One might object to Self-Knowledge, arguing that we aren’t always aware of what we fail to intend.  One might falsely believe one intends the means (Bratman 2009a) or one might simply fail to notice that one hasn’t intended the means (Brunero 2005a).  One response available to the cognitivist would be to say that such lapses in self-awareness are possible, but are theoretically irrational.  And so instrumental coherence would be explained by Closure, Belief Consistency, and the requirement to be aware of one’s absent intention in this context.  While it wouldn’t be plausible to claim that rationality requires, in general, awareness of what one does not intend, it might be plausible to say that awareness of what one does not intend is rationally required in this specific context (Wallace 2006, 118).
