Myers-Briggs audience analysis
Prior to my current freelance career, I worked for a major management consulting firm. That particular firm is completely and utterly obsessed with the Myers-Briggs Personality Indicator. They use it for team dynamics analysis, cultural communications analysis (The United States is INTJ btw) and all kinds of other categories. The one thing, though, that I never saw was a presentation preference analysis. Well, until now!
Check out this awesome article from the Keirsey Personality Zone about presentation preferences so you can avoid having your feelings hurt: http://www.keirsey.com/personalityzone/wz57.asp
(Yeah, it’s technically not MBTI, but it’s pretty darn close and certainly worth checking out!)
