Agreed. What might have been more informative would be to have instead sent them each other's profiles (or all the same profile) and see if they rated them as accurately when applied to themselves.
Not to step on jameshart's toes, but isn't that exactly the business model of astrology, using astronomical positions as a poor pseudorandom number generator to shuffle the profiles? They seem to do pretty well at convincing people not indoctrinated to make fun of them.
