I've posted this on the 5 enneagram forum but this relates to your point on Sx/Sp conflict being exacerbated so I'll repost: I am a 5w4, followed by 8, 3, 1, 6, 7, 9, 2. So it was not a surprise to get 548 for the Tritype. For Instinctual Variance, I'm an Sx/Sp stacking. Here's something I read on these combinations: "While social and self-preservation fives are more removed from their emotions, the sexual five is intense, romantic, and more emotionally sensitive. These five suffer more, resembles the four more, and have more overt desires. This is the countertype among the fives. While they can appear reserved or laconic on the outside, sexual fives have a vibrant internal life that is highly romantic. Trust is the basic issue with the sexual five. Fives tend to be private people, but this five have a great need for intimacy under the right circumstances- if they can find a person they can trust to love them despite their flaws. The sexual five's search for a high exemplar of connection is so exacting that it's hard to pass their test with consistency if you are the person in a relationship with them." I think an INTJ as myself, with a 5w4 sexual variance, ILI Socionic subtype, 458 The Scholar (alleged darkest) tritype, and a Choleric temperament, I am selective with logic and emotion due to my perception of time and judgment of trust. On people, my Choleric Temperament like, an ENTJ would push aside love or friendship bureaucratically, which contradicts or teases the sexual five's need for intimacy - so there's this opposition, plus there's the 8's fear of powerlessness. - Like you, JocktheMotie, I am usually indifferent to other's opinions about myself, but the indifference I've seen depends on my judgment of the person's intentions and the context of my situation. Don't actively seek acquaintanceship unless it is something I'm working on and I see use. I have met this ENTP, who seems to be someone I'd want the bond of friendship with - it might be a meeting of the minds.
