Well, a bite is a bite and whether it's done on purpose or without them meaning to, it will hurt just the same. And you will be surprised how many people would stop handling a parrot after a couple of bites they got simply because they did not know what they were doing in the first place.
I don't agree with the 'no reaction' to a bite. I think it's ludicrous to think that a parrot would confuse the excitement we might show to a fun game with the reaction to pain. Parrots are highly intelligent and, because they are imprinted to humans, they are also masters of the human body language and tone of voice so they know very well the difference between an exclamation of pain and an exclamation of joy. I know this is repeated over and over in birdsites but then, the height dominance theory and the flock leader thing was also repeated over and over until they were both debunked by people with common sense. Furthermore, anybody who has had two birds which don't like one another knows for a fact that parrots don't take bites from another one without reacting (they squawk and either fly away or retaliate) so why would it help for a human not to react? The only thing I can think of is that the bird will think people are either crazy or insensitive to pain and that would not help when one is trying to get them used to not biting. Think about it.
There are very few birds that are aggressive enough to attack without provocation and that's the ONLY time a person can justify getting bit (well, except by accident, of course), any other bites are entirely preventable and due to our own mistakes in handling the bird.
