After having viewed a recent post by Gworley I noticed that the material was deliberately opaque*. It's not as complicated as it seems, and should be able to be taught to people at lower than "Level 4" on Kegan's Constructive Developmental Theory. The only serious block I saw was the ridiculous gap in inferential distance.
With that in mind I was hoping someone might have recommendations on even tangentially related material as what I have now appears to be insufficient. (Simplifying CDT appears to be manageable, but not particularly useful without further material like Kantor's Four Player Model and Subject-Object Notation.)
*edit: Not Gworley's, it was Kegan's material that was opaque.
