title: The 0/0 problem in the fuzzy-logical model of perception.
abstract: The "Fuzzy-Logical Model of Perception" (FLMP) has often been questioned for its presumed ability to fit any data, but no clear-cut evidence has been presented yet. This paper demonstrates the ability of the FLMP to fit random data in the "McGurk region," that is in conditions involving conflicting stimuli. This is due to the so-called "0/0 problem," consisting in the fact that any audio-visual response can be fitted by the FLMP if the audio and visual stimuli provide at least one null probability in each possible category. The consequence is a high instability of the root mean square error in the region of the best fit.
