Enneagram is even more Baby's First than the Baby's First Personality of Socionics. The roots are interesting, but R&H commercialised it and put it in competition with things it's not competitive against. Like actual personality science, or psychology/psychiatry. I suppose the magic is based on your choice of bricolage. Are you an enneagram shaman, or a psychiatry shaman? Pick your dead chicken.

People like it and find it credible because people like structuring narratives and are basically credulous, and are typically not exposed to the exciting world of things that do the Enneagram's job better than the Enneagram.

Brb, accepting ILI typing.

(As a history note, this site started as a way of connecting Oldham types and Socionics. Now look where we are. This forum has really gone downhill.)
