Schlenker 2009, 2010a,b provides an algorithm for deriving the presupposition
projection properties of an expression from that expression’s classical
semantics. In this paper, we consider the predictions of Schlenker’s
algorithm as applied to attitude verbs. More specifically, we compare
Schlenker’s theory with a prominent view which maintains that attitudes
exhibit belief projection, so that presupposition triggers in their scope
imply that the attitude holder believes the presupposition (Kartunnen,
1974; Heim, 1992; Sudo, 2014). We show that Schlenker’s theory does not
predict belief projection, and discuss several consequences of this result.
