Fuzzy logic is not crap, and the fact that you are comparing it to statistics in this manner shows that you have little understanding of either. Fuzzy logic is just like binary logic only it allows for partial truth. Probability relates to how likely something is to happen. To take an example (I didn't make this up, but I don't remember the source): If you take a series of data points to determine whether or not I am in my living room at 7:00 on any given evening and determine that the probability is 50%, that means that I am in my living room 50% of all nights. However, if you give me a 50% fuzzy logical value of being in my living room, this means that I am lying in the doorway between my living room and my bathroom, such that exactly half of my body is in one place and half of my body is in another. These are two different things and the mechanisms do not apply at all to the same problem sets. http://en.wikipedia.org/wiki/Fuzzy_logic#A_new_way_of_expressing_probability http://en.wikipedia.org/wiki/Fuzzy_logic#A_new_way_of_expres...

False. Maybe you're thinking of frequentist statistics?

"However, if you give me a 50% fuzzy logical value of being in my living room, this means that I am lying in the doorway between my living room and my bathroom, such that exactly half of my body is in one place and half of my body is in another." Or it could mean any number of other things depending on what the "Fuzzy logician" finds convenient. In other words, "Fuzzy logic" can mean anything vague related to numbers. In other words, it's just a buzz word that was trendy in the eighties for quantifying something without any particular logic behind it. In other words, it is crap. I mean, seriously, the "discovery" of Fuzzy Logic involved no original or interesting mathematical machinery whatsoever, it just involved y Lotfi Zadeh coining a word to cover ad-hoc quantifying processes. It's the flimsiest of "pop" mathematics and it hasn't had much following for a while now. Sure you can "use" it in the sense that still engage ad-hoc quantification but you could do that before Zadeh came around.
