'''The SFR''' The Bozo Bit (see SetTheBozoBit) is a crude indicator that doesn't take into account the mind numbing variety of idiots one may encounter in nature. Thus, we propose updating this anti-pattern from a single bit value to a larger structure called the SFR. In the current standard, the SFR is 32-bits, thereby allowing nearly 4.3 billion types of idiot to be distinguished. It is not lost on this author that even this measure is potentially inadequate with global population near 6 billion, and that presently unindexable forms of idiocy may thus already exist in nature. To avoid such gaps as well as unwelcome collisions, we propose extending the SFR to 128-bits, which should be amply expressive for any plausible future growth in either aggregate population or idiot density. ''Silly Fool Register, or something else?'' Stupid Fuck? Why not just the BozoRegister?
