@Princess Zucchini I think the way that the faults associated with each Enneagram type are expressed can be rather misleading. All the head Enneagram types have problems with anxiety. Type 5s typically find their self-worth in childhood and adolescence through their ability to know things deeply. This can be a blessing in the most healthy folks, but it can be a fault if it becomes a way of establishing how we value ourselves over others. Type 5s can collect and hoard their ‘wisdom’ and use it to try to gain ascendancy at the expense of others. This is a subtle but unpleasant sort of greed. It’s rooted in a fear of being inadequate.
I often think that establishing our type, whether in MBTI or Enneagram, can be helped a lot by looking at the negative aspects of the type. I found that exploring inferior Se helped me to confirm INFJ as my nearest match. Looking at the insecurity and the use of knowledge to establish my social rank in my adolescence confirmed my E5 as most likely. The E5 was not an ideal by itself though and it’s only when I looked in depth at E5W4 that I found a plausible home in that type system.
I think that a major characteristic of E6 is that this type is a born follower. In its intermediate levels and below, in health terms, E6 folks go with the herd and feel dangerously exposed if they are socially out of place in terms of world view and opinion. E5 types will also go along with the crowd when things don’t matter, but their private views are anything but conventional, and they don’t give a damn about the crowd on things that matter to them. E6 will typically get their sense of identity from the crowd they attach to, E5s from what they know.
Incidentally, E4s have a problem with their identity - many of them don’t know who they are really. They try to find themselves in the eyes of others, but at the same time they are highly individualistic - so they can end up in an identity dilemma. I don’t think that E5 or 6 usually have any problems with their own identity - they may be wrong in who they think they are but they have no doubts in it, whatever they see themselves to be.
This is all steam of consciousness so I hope it makes sense.
