When I first started studying the Enneagram personality type system, what I noticed most was that authors couldn't agree on the Enneagram types of famous people. I remember reading one book that claimed Marilyn Monroe was a type 6 (seeking a father-figure), another said she was a type 2 (seductive), another claimed type 4 (depressive - committed suicide) and yet another had her as a type 3 (presenting a public image).
