Intuitive subtype is the more introverted INFJs. They spend more time using Ni and Ti and less time using Fe and Se. The ethical subtype is the more extraverted INFJs who tend to have stronger preference for Fe and Se and thus spend more time extraverting with people. You can tell us apart here on this forum, which are the Fe/Se-INFJs and which are Ni/Ti-INFJs, it shows in posts. Some INFJs are actually smack in the middle and thus don't belong to either subtype. You can distinguish subtypes of other types as well, INTJ, ENTPs, ESTPs, etc.
Here are the descriptions of the two subtypes:
INTUITIVE INFJ:
Facial expression is typically interrogative, and they seem calm, dreamy, and contemplative. Their line of behaviour is frequently passive. Romantic spirits. They live in the world of illusions, and they attempt to avoid negative emotions. They can be optimistic. They shrink away from conflict situations and support compromises. They are restrained in their clothing, elegant and refined. They can fulfill the functions of an abstract thinker, work in psychology and psychotherapy.
The intuitive subtype appears as a quiet, tactful, languid and diffident individual. They seem torn off from reality, inert and poorly adapted to life. However, such impressions are erroneous, for they possess a fine intuition, which aids them in establishing useful connections and obtaining support from influential people. Seem externally serene but sentimentally are disposed to experience moodiness and bouts of melancholy. While their voice at times seems monotonous they often induce a light surprise, even full interest, from the interlocutor. Outwardly are pensive, slightly strained/intense. Prone to emanate sadness masked in sardonic irony. Speech is measured, smooth and intimately heart-felt. On their face they almost constantly exude a polite half-smile that easily wins people’s trust. Gestures are modest, shy. Gait is ponderous, elegant.
ETHICAL INFJ:
Flatters and is charming and communicable. If they see negative emotions in the people around them, they will try to arrange things so that people will calm down. They will mobilize well in dangerous situations. Loves to be in the centre of attention and dramatize proceedings, possesses a sense of humour. They easily manipulate by intonation and voice; can work successfully as a journalist --- They easily succeed in enticing the person they talk to. Outwardly they can appear extravagant; frequently takes a bohemian and bright form.
The ethical subtype provides the impression of a soft, charming and emotional person. Usually look inspired and optimistic. Possess a fine sense of humor allowing them to list their problems and failures while smiling. Are ironic, crafty, unpredictably and inconsistent in behaviour and conversation. Creating original contrasts, they can unexpectedly prick and then just as quickly embrace/kiss. Artistic and charming; are eloquent in dialogue, occasionally portraying shades of familiarity and impudence. They’re generally affable, kind and careful. Easily draw attention and thereby attract people; talent towards persuasion: states requests in such a manner that it is difficult to refuse them. Movements are graceful as is their gait. Speech is emotional, rich with shades, sometimes melodious.
