Sure, but humans aren't perfectly accurate...
Early tests with bayesian classifiers, on the false postive rate, tended to indicate that building a classifier with a lower false postive rate than the humans was pretty easy.
Certainly my own experience is that I occassionaly tag things as junk, or mis-moderate messages to mailing lists. my own false postive rate is probably less than 1% spammassassain's is much lower than that. false negatives however are a reason I sitll have to tag things.
