Core type-
Passion: lust.
E8s think that anything worth doing , should be done all the time, similar to e7s gluttony. However lust is more focused on physicality, this is usually stereotyped as aggression.
Fixation: vengeance.
They feel as though their wrongs can be forgiven by being angry at- and blaming external factors.
Trap: justice.
They have a good grasp on how unfair our world is, they’re very sensitive to actions they deem unfair towards themselves. Their response to this is revenge, as it would balance the two wrongs.
Defence mechanism: denial.
E8s avoid being seen as weak, and feeling vulnerable at all times. Through denial they block out any thought, feeling and need they see as vulnerable or weak, and refuse to accept situations in which they are these things.
Virtue: innocence.
In order to admit to themselves, they need to learn that vulnerability is okay, and immediate reactions to external, often unnecessary, judgement, whether made by themselves or others, aren’t needed.
Key traits:
Anger and the willingness to confront, rebelliousness, punitiveness/revenge, dominance, insensitivity, autonomy, sensory-motor dominance.
Subtypes-
Self preservation [sp]:
Sp8s are usually more introverted and don’t care as much about expressing their desires. They want to get what they need without communicating it, this can make them seem overly impatient with others. They’re very independent and know how to get what they want really well. All this can make them look overly egocentric and selfish.
Sexual [sx]:
The sx8 is more of a leader type. They want people to look at them and be the centre of attention, usually they strive to achieve this through rebellion and being good at expressing what they want and how they want it. Though they want to lead, bigger groups aren't their thing, they often feel like they might lose control over the people they’re supposed to have all the attention of.
Social [so]:
The so8 is more friendly and caring than the other subtypes. They want to rebel against social norms and help people out who they think of as weaker than them. They want to be able to protect those who struggle in environments they understand, due to this they want to gain knowledge over these environments.
Contradictions-
INTJ, INFJ, ISTJ, ISFJ, INTP, ISTP, INFP, ISFP, ENTJ, ESTJ, ENFJ, ESFJ, ENTP, ENFP
Most importantly, e8 is exclusive to se dominance. While this seems like an excessive limitation, it becomes obvious by their value for tangible reality, sensory motor and lust. One thing people tend to get wrong about e8 is assuming it could be compatible with judging functions, especially Te. While Te and Se can sometimes appear similar, the deciding factor here is the fact that Te still prefers thinking over doing, while e8 wants the opposite. A similar case can be made for intuition, however this would be more focused on intuitions abstraction and e8s realism. Some people have considered sp8 to be on the debatable side of things when it comes to ISTP and ISFP, however I personally disagree and find the introverted and judging dichotomies to be contradictory for the reasons I named previously.
Types you might want to look into if you are on this list are e2, e3, e4, e6, e7 and e9.
