  An FA theory of humor agrees with dispositionalism that the funny can only be characterized in terms of a human response (amusement); but it also holds, with robust realism, that the amusement of even normal humans in standard conditions can be mistaken: it can be unfitting. To call something funny is in some way to endorse amusement at it, not to report or predict it. The attraction of FA theory is that it purports to capture the sense that we ought to be amused at certain things because they are funny, as robust realism has it, while agreeing with dispositionalism that funny cannot be understood except by way of human response and sensibility: our sense of humor.
