Still determining my type, so just some interesting personality-type quotes/comments: 
"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." 
"Chameleons hide their true selves." 
"One-to-one conversation is preferred in almost every situation. In a group situation, INTPs are sensitive to whether they believe they will be listened to or not." 
"On the other hand, one of the more serious weaknesses of an INTP is that the sensing function makes little inroads out into the external world. INTPs are usually oblivious to external details unless something forces them to take notice. When an INTP goes into a new room, or walks through a city street, he is blind to much of the detail that people with an Se function would see immediately." 
"The one thing that will force an INTP to tidy his home radically, even when alone, is when the clutter eventually gets in his way and hinders some activity." 
"The homeland of the INTPs psyche is a small and cosy community, isolated in the middle of a vast expanse of wilderness." 
"INTPs are usually fascinated by music and may have deep and wide-ranging tastes. Indeed, each of their three main functions (Ti, Ne, Si) plays a role in the enjoyment of music, and indeed music is a key interest for bringing out the feeling shadow of the INTP." 
"INTPs are also drawn to complexly structured music, thanks to their Ti core. An appreciation of modern classical music, as well as perhaps contemporary jazz, is therefore common with them." 
"Examples of modern classical composers who particularly speak to the Ti core might be Simpson, Arnold, Holmboe, Maxwell-Davies and Shostakovich." 
"The role played by the Si function is shared by SJ types, so that INTPs may find a common musical bond with some SJs in this area. Indeed, INTPs often feel at ease with SJs, especially their near-shadow xSFJ types." 
"It is interesting to observe that the external world of the INTP involves a very free-spirited Ne-Fe partnership, while the internal world is a very clinical detail-structure-analysis Ti-Si combination. Hence, the outward behaviour of an INTP can contrast strongly with his introspective world." 
"Hence, when an INTP does finally respond emotionally to something, his emotions are indeed left uncontrolled, raw and open." 
"It is easier to choose appropriate music than to attempt to influence this. People with introverted Feeling, Fi, however, will deliberately choose to listen to music which helps them change and improve their mood. INTPs could never do that. 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." 
"Nevertheless, in an intimate relationship, the extraverted nature of the feeling judgement leads to a beneficial openness and empathic directness in responding to the partners needs, providing the healthy development of the Fe function is encouraged. Indeed, for many INTPs, an intimate relationship is the only place where the Fe shadow can really develop fruitfully." 
"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 T-based solutions. Much worse is when the emotional person appears to be being irrational." 
"The feeling shadow is the fear centre of the INTP." 
"Resigned acceptance of the unacceptable is an anathema for INTPs. His typical response to helplessness is to hate the world which has produced it. However, the greatest fears of an INTP are usually ideas generated within his own mind."
