Don't know why this is seen as legitimate. MBTI makes the bad assumption that people that fall on either side of a bell curve (say in terms of extraversion) are categorically different people. More self-fulfilling than anything.
The way it was explained to me is that the letters are vastly less useful alone than with the scores. The score you get says where on that bell curve (approximately, depending on how well-posed the questions were) you lie in each of those scales. Not predictive by any means, but possibly insightful.

Actually, MBTI makes no such assumption. Popular culture makes that assumtpion about MBTI.
