I'm currently reading the book mentioned above; I'm wondering about
something...

He attempts to define the membership function of a set by using 
what he calls ``calibrational propositions'' -- the idea is that if
you ask 70 people if John is tall, and 70 of them say ``yes,'' then
mu(tall) = .7.  While this seems to do a good job of capturing common
word usage, it's not at all clear to me that it captures the fuzzy
behavior of the ``tall'' set; it seems probabilistic rather than
fuzzy.

So, what are other people's reactions?
