We shouldn't trivialize Jung's and Myer's work because of the pop culture surrounding it. Psychological Types and it's surrounding works (though, I haven't read The Red Book yet) contain a great deal of insight.
Agreed that Jung is still a fine historical and useful psychological figure. However, this was 80-100 years ago. time moves on. I didn't really want to start a MBTI storm, but it was illustrative of a categorisation-creation issue, and the limitations of doing quantitative (and pseudo-quantitative) academics without well-grounded variables.
