The Mechanic (Introverted Thinking with Extraverted Sensing)

As an ISTP, your primary mode of living is focused internally, where you deal with things rationally and logically. Your secondary mode is external, where you take things in via your five senses in a literal, concrete fashion.

ISTPs have a compelling drive to understand the way things work. They're good at logical analysis, and like to use it on practical concerns. They typically have strong powers of reasoning, although they're not interested in theories or concepts unless they can see a practical application. They like to take things apart and see the way they work.

ISTPs have an adventuresome spirit. They are attracted to motorcycles, airplanes, sky diving, surfing, etc. They thrive on action, and are usually fearless. ISTPs are fiercely independent, needing to have the space to make their own decisions about their next step. They do not believe in or follow rules and regulations, as this would prohibit their ability to "do their own thing". Their sense of adventure and desire for constant action makes ISTPs prone to becoming bored rather quickly.

ISTPs are loyal to their causes and beliefs, and are firm believers that people should be treated with equity and fairness. Although they do not respect the rules of the "System", they follow their own rules and guidelines for behavior faithfully. They will not take part in something which violates their personal laws. ISTPs are extremely loyal and faithful to their "brothers".

ISTPs like and need to spend time alone, because this is when they can sort things out in their minds most clearly. They absorb large quantities of impersonal facts from the external world, and sort through those facts, making judgments, when they are alone.

ISTPs are action-oriented people. They like to be up and about, doing things. They are not people to sit behind a desk all day and do long-range planning. Adaptable and spontaneous, they respond to what is immediately before them. They usually have strong technical skills, and can be effective technical leaders. They focus on details and practical things. They have an excellent sense of expediency and grasp of the details which enables them to make quick, effective decisions.

ISTPs avoid making judgments based on personal values - they feel that judgments and decisions should be made impartially, based on the fact. They are not naturally tuned in to how they are affecting others. They do not pay attention to their own feelings, and even distrust them and try to ignore them, because they have difficulty distinguishing between emotional reactions and value judgments. This may be a problem area for many ISTPs.

An ISTP who is over-stressed may exhibit rash emotional outbursts of anger, or on the other extreme may be overwhelmed by emotions and feelings which they feel compelled to share with people (often inappropriately). An ISTP who is down on themself will foray into the world of value judgments - a place which is not natural for the ISTP - and judge themself by their inability to perform some task. They will then approach the task in a grim emotional state, expecting the worst.

ISTPs are excellent in a crisis situations. They're usually good athletes, and have very good hand-eye coordination. They are good at following through with a project, and tying up loose ends. They usually don't have much trouble with school, because they are introverts who can think logically. They are usually patient individuals, although they may be prone to occasional emotional outbursts due to their inattention to their own feelings.

ISTPs have a lot of natural ability which makes them good at many different kinds of things. However, they are happiest when they are centered in action-oriented tasks which require detailed logical analysis and technical skill. They take pride in their ability to take the next correct step.

ISTPs are optimistic, full of good cheer, loyal to their equals, uncomplicated in their desires, generous, trusting and receptive people who want no part in confining commitments.

Jungian functional preference ordering:

Dominant: Introverted Thinking
Auxiliary: Extraverted Sensing
Tertiary: Introverted Intuition
Inferior: Extraverted Feeling

ISTPs are generally extremely capable individuals who are good at most things which interest them. They are usually bright, interesting, and exciting individuals with a lot to offer. They live almost entirely in the present moment, and usually do not make commitments beyond the immediate foreseeable future. An ISTP probably coined the phrase "nothing is unconditional". They strongly prefer to take things one day at a time, rather than make long-term commitments. If a relationship interests them and satisfies their needs, the ISTP will do their part on a daily basis to keep the relationship strong and healthy. If they lose interest in a relationship, their natural tendency will be to move on.

ISTPs have an enthusiastic, childlike approach to life that is attractive to others. As Introverted Thinkers, they also have some real substance to them which prevents them from being entirely frivolous and hedonic in their pursuits. They are laid-back and flexible, and generally accepting of a wide range of behavior. These attributes make them valued friends and confidantes.

ISTPs usually have a selection of friends who share their love of particular hobbies and pasttimes. They might have a friend who they ski with, and another who they shoot pool with, etc. They generally have no interest or patience with individuals who do not share their interests, and will spend little or no time with them. They have a difficult time understanding people with extremely strong iNtuitive preferences, and are not likely to spend time with these individuals unless they share a common interest or hobby. They enjoy spending time with Extraverts, whose enthusiastic, talkative natures are attractive to the more reserved ISTP, but they will eventually tire of their "bubbliness". The ISTP is able to get along well with people of any personality type, but is likely to value and bond only those with whom they have common interests.

ISTPs can be very intense and exciting individuals. Their strong Thinking preference makes them seem rather aloof and "hard to get". Their Sensing and Perceiving preferences make them sensual, earthy individuals. These attributes frequently make them attractive to the opposite sex. ISTPs live entirely in the current moment, which makes them especially interested in new sensations and experiences. They strongly dislike routine and strict schedules, and resist being controlled by others. They are fiercely independent and need their own space within a relationship. When involved in relationships which provide for their basic needs and which present them with new experiences, the ISTP will be happy to do what's necessary to keep the relationship alive and well. If a relationship becomes boring or oppressive to the ISTP, they will try to fix it, or move on. ISTPs take their commitments on a day-by-day basis. Even if they say "I do", it usually means "I do for now". They do not like to make lifelong commitments, although they may very well be involved in lifelong relationships which they have taken one day at a time.

Sexually, the ISTP approaches intimacy as a physical act rather than an expression of love and affection. They are earthy and sensual beings who enthusiastically experience sex with all five senses. They bring spontaneity, creativity, and enthusiasm into the bedroom, and enjoy new experiences. Since aesthetic beauty has such strong appeal to them, they appreciate the "setting", i.e. bedding, lingerie, cologne, etc.

ISTPs love to fix things, and may create problems in their personal relationships, just so that they can have the fun of fixing them.

They have a tendency to hold back their own views on things. They like to listen to other people's views, but are generally non-commital about expressing their own opinions. ISTPs have a habit of evading answering questions by asking more questions. This can be frustrating at times to their mates, if they are after a direct answer. The ISTP's decision making process is entirely internal, so they don't feel much need to share their opinions with others. When they are interacting with others, they are in "information gathering" mode, so they tend to ask questions rather than share views. The ISTP just doesn't feel the need to expose themselves fully to others. When it comes to intimate relationships, the ISTP has the further motivation of protecting themselves. Most ISTPs are afraid of having to deal with their deeper feelings. Since their Thinking preference dominates their personality, their Feeling side is their least developed (inferior) function. Consequently, ISTPs are usually quite vulnerable and perhaps weak when dealing with their feelings. Their habit of keeping part of themselves hidden may also serve the purpose of keeping a protective wall around their hearts.

Although the ISTP does not usually have a well-developed Feeling side, they frequently do have intense feelings for people. They can feel overpowering love for their mates, although they are likely not to express their emotions, or to express them inadequately or inappropriately if they do venture towards expression. However, unlike many of the other personality types, ISTPs feel strong affections one day at a time. One day, they may feel completely, intensely in love with their mate, and the next day they may be totally disinterested, or perhaps even ready to move on. This "live for the moment" type of approach is different from how most other types experience their feelings, and is difficult for many to understand. Consequently, the ISTP may be called "fickle" or "cold". In fact, they are not really fickle, and certainly not cold. They simply experience their lives on a moment by moment basis, and go along with it's natural flow. However, since most people need more commitment than can be offered when taking things day-by-day, the ISTP who wants to remain in a relationship will have to resolve themself towards being involved in a more traditional commitment. For most ISTPs, making a commitment to an intimate relationship will require an effort to stretch themselves outside of their comfort zones. However, those who do so will realize that they can enjoy the benefits of a strong, committed relationship and still live their lives in the present tense.
