 Intuitively, it would be appropriate for Stella, as a teacher, to assert  (31).  However,  (KNA)  predicts that  (31)  is incorrect, because Stella does not believe, and therefore does not know, that  (31)  is true. Selfless assertion have generated a lively debate, mostly involving attempts to explain their propriety within a  (KNA)-framework  (see Montminy 2013a, Turri 2015, Milić 2017).
