Hmm Siamese. This is what I read about in Personality Types: Using the enneagram for self-discovery by Riso and Hudson.
(It actually points out flaws in Jung's system, so others may be interested in this):
"The nine personality types of the Enneagram can also be correlated to the 8 'psychological types' of the Jungian typology.
To review Jung's system, he posted that there are two general psychological attitudes(extroversion/introversion), and 4 psychological functions(thinking, feeling, intuition, and sensation)...which yields 8 personality types. (They did not include P/J)
Correlations:
1=extroverted thinking
2=extroverted feeling
3=no correlation
4=introverted intuitive
5=introverted thinking
6=introverted feeling
7=extroverted sensation
8=extroverted intuitive
9=introverted sensation
A close reading of Jung will reveal, however, that sections of the descriptions of several of his types do in fact correspond to the Enneagram type 3. Jung inadvertedly described some elements of the 3 without considering this type as a separate psychological entity, something which would have thrown off the symmetry of his 2x4 theoretical framework.
Besides its not being comprehensive enough, there are several other problems with Jung's descriptions. Unfortunately, not all of Jung's descriptions equally worked out, and it is not always easy to understand what he is trying to describe.
From the point of view of the Enneagram, we can see that Jung usually describes some of the traits of the average person in each psychological type, freely randing around what we could consider to the Levels of Development(healthy vs. unhealthy, the 1-9 levels I described). Occasionally, however, he confuses traits of one type with those of another--as when, for example, he describes elements of Enneagram type Nine as if they belonged to the introverted feeling type(type 6). There are also confusions between other types, for example, between elements of the introverted and extroverted thinking types(types 5 and 1). There are other confusions as well."
Hmm, I guess there are basic correlations, but what you're saying about correlation among the other types, Riso & Hudson are saying that was just wrong on Jung's part.
It's all really interesting. Very cool to know someone else knows about the enneagram!
