Can I also suggest:
Q: I just got a spam, but the system said it was "unsure". Why
couldn't it tell that it was spam - it's obvious?
A: It may be obvious to you, but the classifier only works on
the information it has been given. Maybe this is "new" (you've
never seen this particular flavour of spam before), or maybe
there aren't enough clues in the message which the system is
aware of as strong spam clues.
Q: OK, I trained on that message. But I just got *another* one,
and the stupid system still thinks it's unsure. Why did it
A: It didn't, but you may need to train on a few more of this type
of message to get it classified as "spam". The classification
algorithm weights its results based on the number of times it
has seen a particular clue, so that clues unique to this type
of message may need a few more instances to become "convincing".
