Yeah socionics and jung don't always mesh. Like he says they wear a banal childish mask and i have seen this in EII more than ESi. I do think that in order to explain stuff like the following you need some enneagram and instincts. Not to mention that fact that people are way more complex than any of these systems can account for. Mental illness is going to skew things a lot too.
EIIs are usually very straightforward about their feelings in front of others; what you see from them is what you get. Even at a party where everyone is supposed to be happy, they still find it hard to conceal their true feelings when they are in a bad mood. This can create distaste among the rest who feel that the EII is not cooperating by contributing to the positive and boisterous mood. This tends to lead others who don't know the EII well to have a misconception that he/she is a grouchy person by nature.Extroverted Ethics (Fe, )
ESIs may sometimes be concerned with maintaining a positive emotional environment, sustaining a group mood, having fun and joking, etc. -- but usually do not focus towards this end as much as they do towards the internal experience of their emotions, and they usually see no point in maintaining a group atmosphere if they do not already have a positive attitude towards the people involved; they may simply be inclined to walk away and not participate in an atmosphere generated by individuals they dislike, which may be seen by others as judgmental and spoiling the mood.
ESIs may have difficulty interacting in environments where the air is openly hostile and unfriendly and can seek to ensure that others maintain minimum standards of cordiality and decency, especially if the environment is constituted by people they care about. However, at other times they may be responsible for and willing to sacrifice a friendly atmosphere by censuring others whom they see as reprehensible. In general, ESIs' sense of moral integrity and conscience is more influential in their decision making.
Though ESIs often show a degree of conscientiousness as to the way others respond to their actions, this tends to be only their driving motivation to base their actions on the expected reactions of others inasmuch as their personal relationships are at stake. They may at times be surprisingly blunt in their communications, instead taking a pragmatic approach towards disseminating rather direct advice.
I guess it correlates somewhat and perhaps I am just better at reading their emotions than some other types would be. So when I say they can't hide I am saying they are not hiding it from me.It is principally among women that I have found the predominance of introverted feeling. "Still waters run deep" is very true of such women. They are mostly silent, inaccessible, hard to understand; often they hide behind a childish or banal mask, and their temperament is inclined to melancholy. They neither shine nor reveal themselves. As they are mainly guided by their subjective feelings, their true motives generally remain hidden. Their outward demeanour is harmonious, inconspicuous, giving an impression of pleasing repose, or of sympathetic response, with no desire to affect others, to impress, influence, or change them in any way. If this outward aspect is more pronounced, it arouses a suspicion of indifference and coldness, which may actually turn into a disregard for the comfort and well-being of others. One is distinctly aware then of the movement of feeling away from the object. With the normal type, however, this happens only when the influence of the object is too strong. The feeling of harmony, therefore, lasts only so long as the object goes its own moderate way and makes no attempt to cross the other's path. There is little effort to respond to the real emotions of the other person; they are more often damped down and rebuffed, or cooled off by a negative value judgment. Although there is a constant readiness for peaceful and harmonious co-existence, strangers are shown no touch of amiability, no gleam of responsive warmth, but are met with apparent indifference or a repelling coldness.
Edit: still talking about people I know well. Not online people.
