I've read this thread just now, gives all this a bit more meat.
Now I understand that my neighbors have serious issues.
Dominant-Tertiary Loops and Common Personality Disorders
I've underlined their symtoms.
ESTP/ENFJ: Se/Fe or Fe/Se--Histrionic Personality Disorder. This tends to manifest itself in terms of exaggerated, aggressive sexual behavior and physical impulsiveness. Since reflecting the outer world is the only thing that matters, whatever will shock, impress, or otherwise affect others enough to include the user in their social rituals is what has to be done. Real empathy is rare as this type requires constant thrills or conflict--in the ENFJ version, this often results in excessive sensitivity to perceived "rudeness" or failure to respect the user's preferred cultural custom (Fe), combined with tertiary Se responding aggressively through implied threats of brute force. (e.g., Vito Corleone: "I'll make him an offer he can't refuse"--gives a surface appearance of respecting the cultural standards of negotiation, but implies that refusal to accept this "offer" would be quite unpleasant for the recipient!) If Ti/Ni were doing its job, the user would find a sense of balance and comfortability with himself, granting him the ability to discover what is subjectively important to him, rather than constantly shifting with the tide of cultural and social trends.
ESFP/ENTJ: Se/Te or Te/Se--Obsessive-Compulsive Personality Disorder (not the same thing as OCD)! I've seen people mistake ESFPs in Se+Te dom-tert loops for ESTPs because they can be so insistent upon controlling their surroundings. These types epitomize enneagram type 8, as they are aggressive, blunt, confrontational and not the least bit afraid of hurting anyone's feelings. Inside they require the approval of others to a much higher degree than they let on, as Te insists on controlling and organizing external surroundings to ridiculous proportions, while Se pushes any naysayers out of the way with aggressive force and a take-no-prisoners attitude. Territorial and looking for any reason to display their power, these types are some of the most difficult to deal with of all dom-tert loops. If Fi/Ni were doing its job, these types would stop to consider that their actions have negative implications for others, and that aggressively taking charge is not always the best solution in every situation.
