Ok I’m back with a response after my earlier premature reply about the high strung aspect. I’m glad you have talked to others. I haven’t found the others yet. If they are also INFJ this would be really interesting. You see INFJ 5 have higher Ti it is not merely an Enneagram for us. We literally cognitively process differently and are more of the INFJ and less of the INFJ at the same time; an intensified version of the INFJ strengths and weaknesses. I had a tribe with my 5s. Perhaps some of these INFJ 5s have higher IQ but INFJ 5s differ from one another in that we all have high TI and have massive NiTi loops that we don’t really see as a problem but INFJ 5s other cognitive functions vary from one another. I had very high Ni high Fe high Ti barely existent Se. perhaps that’s the other factor low Se. but my cognitive function stacks weren’t very typical. Now all including my Se are quite high. I fit perfectly with my 5s. Now though I’m a 2 I have a less common formula than I did before. It’s such irony. I think INFJ 5 may be more susceptible to this possibility of transformation because having really high Ni hence INFJ and higher Ti the NiTi loops become an art form and there is always learning. This is the never changing aspect more answers more questions more answers and so on. Very analytical and multidimensional are the INFJ 5s.
