I hope it's not because I suggested that you know more about yourself than the Briggs people do!
Initially, my question was simple aimed at whether the test revealed anything about you that was surprising. It was curiosity, not ridicule. I only asked because my general impression is that people can tell you about themselves without long questionnaires.
But, when they have nothing to lose by it, people also like doing quizzes, enjoy having some aspect of their character reflected back. I'm not sure why that is - maybe it's like talking to the mirror on the wall. In that sense, it can also benefit the test-taker by reminding him of behaviours that could be modified.
I've never believed that these personality tests administered to prospective employees are particularly useful; I think they are an invasion of privacy, and I'm very much against them as a condition of being considered for a job. The applicant is qualified or not; their inner self, or self-image is no employer's business.
But I can see that such tests - in fact, now that I think of it, any of those quizzes they used to have in magazines - may be helpful in starting a discussion among peers, colleagues, teammates, even families, to promote better understanding.
I can't speak for anyone else, but I gained some insight from this discussion.
