When getting into a new relationship, INTPs can lose their rational and dispassionate thinking for a very long time (a year or even more), “immersing” themselves in the new unknown world. If an INTP falls in love, it is extremely powerful – it is all or nothing. It is very likely that this phase will see the INTP become very ardent, even playful and careless. The INTP will be prepared to do many things and bend many rules to be with their loved one, no matter how difficult that might be
INTP personalities deeply value their commitments to the partner, but are unlikely to discuss such topics with other people for a very simple reason – commitments of this nature seem perfectly logical and natural to an INTP.
As for the INTP criteria, knowledge and intelligence are at the top of the list – INTPs are likely to seek the friendship of people they expect to possess such traits.
The mystery of emotion is also evidence in the INTP’s use of music. He always chooses to listen to music which suits his current emotional state, be it aggression, warmth, excitement, relaxation or whatever. Hence, the emotional state is assumed to be an unchangeable, mysterious property of himself. It is easier to choose appropriate music than to attempt to influence this. They feel an unpleasant sense of disharmony whenever a music style clashes with their emotional state. Indeed, it is remarkable how much attention they pay to their emotions when music is involved.
INTPs dislike being in an atmosphere of emotional disharmony. If they need to say something unpleasant to someone close to them, they would prefer to avoid this task for fear of the disharmony that may result. This results from the INTP’s fear that he does not have the emotional competence to deal with disharmony. INTPs never like doing something until they know they can do it.
A further result of the i function is the concept, lived out by many an INTP, that knowledge is everything. They tend to believe that information is the key to life. All mistakes can be avoided by having the right information at the right time. This has at least a certain logic about it. Where they differ from other temperaments (especially from SP types) is that a large gap may exist between knowing and doing. To know is everything, to do is a lower order necessity, if it is necessary at all.
The greatest fears of an INTP are usually ideas generated within his own mind. The problem is that the Ti-Ne axis is capable of conceiving very unpleasant ideas, which may be far from reality and even irrational. Ideas and possibilities assume so much importance in the mind of an INTP that they can override a common sense factual grasp on reality.
For the INTP, emotions are seen as something mysterious and as uncontrollable as they are unalterable. Hence, the root of the fear of emotions is the fear that they cannot be controlled. When an INTP does finally respond emotionally to something, his emotions are indeed left uncontrolled, raw and open.
When witnessing the emotional response of another person, the INTP intensely resists any similar emotion of his own. An example of this is when watching a ‘weepy’ cinema film in which some heart-wrenching scene is being shown. The INTP despises the attempt by the filmmaker to influence his emotions and is more likely to sneer than cry. This response has nothing to do with arrogance, however. Rather it is the INTP defensively avoiding exposing what he knows to be his weak point. Where an INTP may experience his own emotional response during a film is when he has had the chance to consider consequences of a element of the film. Hence, emotional response to media input usually occurs with a certain independence of will, which could appear enigmatic to others.
The inferior Feeling shows itself, otherwise, in the lack of ability to show active empathy with people undergoing strong emotions. If he wishes to encourage the emotional person, the INTP tends to resort to giving Thinking-based solutions to the problems involved. Often, the INTP does not really know how to empathize and may feel discomfort and helplessness, especially when he understands the rational basis for the emotions. He may become frustrated that the person remains unhappy in spite of hearing his Thinking-based solutions. Much worse is when the emotional person appears to be being irrational. INTPs detest irrational emotion above all things.
Friendship with INTPs develops at a pace which depends considerably on the temperament of the other person. INTPs dislike making the first move and tend to mirror the emotional content of the other person. A jolly person will quickly bring the INTP out of his shell, as much as that is possible, while a serious person will find a serious INTP looking back at him. INTPs do not do this cynically, or indeed all the time, but it is a result of the strong desire to remain detached and observe.
INTPs hate to think of themselves being in any way inadequate, at least in areas that are important to them. So, as soon as he puts himself behind some task, then he must achieve competency. But that is as far as it goes. Refined competency requires too much effort and has little attraction. It would require practice and that usually bores an INTP. Hence, it is common to see INTPs dabbling at many things, achieving competency, just enough to prove to themselves that they could become more proficient if they wished, but rarely actually bothering to refine their skills further.
The INTP is sometimes referred to as the architect. The world is an object of study and possibilities for changing and shaping it according to the schemes assessed by the Ti core are derived from intuition. If his introversion is strong, however, then his schemes tend to remain private and speculative: the world remains an intellectual object of study but his architectural plans may not actually be put into practice.
