I believe there are many overlaps between enneagram and the Jungian Cognitive Functions. Perhaps others could note the correlations and we could begin a discussion about how they can be seen as transformations of each other.
1 sounds very IJ, Ti, or perhaps Fi
2 sounds ery exfj or perhaps ixfp socionics Fe function
3 perhaps exxp, Se, perhaps exfx or esxx
4 very ixfx especially ixfp or xnxp or perhaps Ni and Fi
5 very ixtx, Te as a non primary but conscious function
I'm sure others could elaborate much more perhaps including type relationships as well
This also begs certain questions. If one can change enneatype between points of growth and points of .. negativity perhaps types can be cycled as well under different stressors
