This posting seems to be about the validity of testing. I suggest
that the "validity" of a test ("evaluation", if you like) be measured by
its predictive power. Predictive as to what? Ahh, there's the subjective
judgment that puts a discussion in context.

you, because that is what I must do. Tonight it is only you and me, fish.
It is your strength against my intelligence. It is a veritable potpourri
of metaphor, every nuance of which is fraught with meaning."
