If you ask someone who finds the Enneagram types useful, you'll probably hear that they are accurate. However, there's a difference between being "accurate" and being "useful." Accuracy is about how well the types describe reality and in particular people's experience. Usefulness is about how well the types help me understand myself and others. There are many models and theories used in psychology and other disciplines that are not completely accurate but are useful. The Enneagram types are one such model.
These blog posts are thoughts I have about the Enneagram types and related projects I'm working on. Many of these relate to the Enneagram User Guide series of books. If you'd like to share your thoughts about one of the blog posts then click on the discussion forum topic(s) below the full post.
