If you're interested I can post his other translated meanings of terms.
If P = Inward Energy and J = Outward Energy, then what do you make of EP / IP / EJ / IJ ? What significance do Extraversion and Introversion have then in this context?
EJs seem to try to persuade / push others to do their bidding.
IJs seem to make up ideas, that they then expound on, and then expect others to follow accordingly, and when they don't, they keep going back to trying to explain to others why they are right.
IPs mostly seem to adapt to whatever is going on, but to get what they want, they act alone, often when no-one else is there to see.
EPs seem to just throw themselves into a situation with others, do what they decided to do, and then hope it works out.
I'd say that the difference between Js and Ps, is that Js do things to get others to act in ways that will get them what they want, while Ps just get on with things themselves, in the hope that the results they are hoping for, will get them what they want.
EJs differ from IJs, and EPs from IPs, in that Extroverts seem to act as if they are part of a group, while Introverts act as if they are acting independently of the group. In EJs, this combination results in them acting towards the group, or as part of the group, to get the group to do what they want. Hence, direct persuasion and pushing.
In IJs, they act independently of the group, but still wanting the group to do their bidding, hence indirect persuasion, such as by giving over rational reasons why their bidding should be the best course of action, and acting expectantly that others should follow suit.
In IPs, the P-ness of adaptation and the I-ness of independence, results in pure action alone, often with almost no-one other than very close friends having a clue what is really going on in their lives.
In EPs, this results in the same independence of action that Ps have, but this time, while still in the group, and still maintaining a communication with the group, giving them the conflicting behaviour of someone in a group deciding to do things within the group that the group don't really understand, but still wanting the group to be involved.
I've seen this mostly in EJ and NF. EJs reprising the leader role while NFs acting as catalysts for action.
EJs are quite pushy. They act ON people.
NFs work with people as a subject in itself. They think of people the way NTs think of machines, as things they intuitively understand the workings of, and how to impress inputs that will result in the desired outputs.
and this mostly in EP and ST. EPs being egoistically ambitious, while STs taking initiative and being pragmatic.
EPs get on with things themselves, while still being within the group. Then they let the group decide the value of their efforts. Because they are acting within the group, but acting independently of the group, this makes them seem as if they expect the group to follow suit, much as the INTJ appears to expect the group to do the INTJ's bidding, just because the INTJ says it is the most rational course of action.
STs are very pragmatic, because they work with things, and they stick to what they know, the familar, usually because what we already are familiar with, has already been investigated thoroughly, and we already know what things can and cannot be done with them, and how they work. So they can just get on with solutions, or immediately say that the thing cannot be done. However, they will stick to the tried and true, no matter if it applies or not. Put an ST in a situation where things are very different from what they are used to, and they go haywire. They keep trying to treat the situation as something they know.
Classic example: ST: "What are you eating?"
NT: "Shmeat".
ST: "What kind of meat is it? Lamb? Beef?"
NT: "No. It's Shmeat."
ST: "Oh. So it's lamb (made from sheep, sounds like shmeat, the closest the ST knows)
NT: "No. It's artificial meat."
ST: "So which kind of artificial meat is it? Lamb?"
NT: "No. It's
artificial meat."
ST: "Now you're just trying to confuse me."
STs can get on with things by themselves, because they have an existent working method that deals with THINGS, and so doesn't need the input of people. But if you ask an ESTJ to bake you a cake, they will put all their cake things in their car, drive round to their friend's, and bake it there, WITH their friend. They need someone else there, to be part of a team.
