There is no direct correlation between the nine Enneagram personality types and Dramatica's eight archetypal characters, through there is some crossover.
2 - The Helper --- Guardian
5 - The Investigator --- Reason
6 - The Loyalist --- Sidekick
1 - The Reformer --- Elements of the Reason archetype
4 - The Individualist --- Emotion
8 - The Challenger --- Antagonist
IF YOU STRETCH IT
3 - The Achiever --- (Skeptic?)
7 - The Enthusiast --- (Contagonist?)
9 - The Peacemaker --- (Protagonist?)
The primary difference between the Enneagram personalities and the Dramatica archetypes is the result of evaluations made from two vastly different points of reference AND looking at two different things.
The Enneagram looks at integrated personality types and organizes them by dominant traits.
Dramatica sees the entire collection of problem-solving functions as the basis for a SINGLE integrated persona and organizes the elements by problem solving functionality.
That's why there are obvious points of intersection and areas of equally clear divergence.
Melanie Anne Phillips suggested to me that the Enneagram personality types could be built in Dramatica's Build Character window and saved using the "Typecast" feature. If anyone is up to the challenge, I'd be happy to make them available to other Dramatica users by posting them to Dramatica.com. Let me know if you're interested!
