Thanks, I'm always looking for a good review of research on the MBTI. Sadly, when I make these points to proponents of the test, it always seems like proponents don't really understand why test-retest reliability would be a problem, or why it matters that there's no basis to promote these four random factors to the center of all personality analysis, or why logical keying would invalidate any personality inventory. That's what makes me think it's pseudoscience most of all: discussion seems impossible. Gladwell also provides some history of the test and some major concerns, if you're more into his style: http://gladwell.com/personality-plus/ http://gladwell.com/personality-plus/
