 A different criticism comes from Sosa (2009), who notes that  (KNA)’s  explanation of Moorean assertions fails to generalize as it should, because  (KNA)  is unable to explain “dubious assertions”: cases in which the speaker asserts p while admitting that he doesn’t know whether he knows that p (but see Benton 2013, Montminy 2013a). Finally, several authors have questioned the assumption that it is always improper to assert that one’s ticket is a loser on purely probabilistic  grounds.[23]
