Identity Crisis
INTP or ISTP?...althought the two are close.

INTP(from humanmetrics.com)

Qualitative analysis of my type fromula
- moderately expressed Introvert
- moderately expressed iNtuitive personality
- slightly expressed Thinking personality
- slightly expressed Percieving personality

INTPs are pensive, analytical folks. They may venture so deeply into thought as to seem detached, and often actually are oblivious to the world around them.

Precise about their descriptions, INTPs will often correct others (or be sorely tempted to) if the shade of meaning is a bit off. While annoying to the less concise, this fine discrimination ability gives INTPs so inclined a natural advantage as, for example, grammarians and linguists.

INTPs are relatively easy-going and amenable to almost anything until their principles are violated, about which they may become outspoken and inflexible. They prefer to return, however, to a reserved albeit benign ambiance, not wishing to make spectacles of themselves.

A major concern for INTPs is the HAUNTING SENSE OF IMPENDING FAILURE. They spend considerable time second-guessing themselves. The open-endedness (from Perceiving) conjoined with the need for competence (NT) is expressed in a sense that one's conclusion may well be met by an equally plausible alternative solution, and that, after all, one may very well have overlooked some critical bit of data. An INTP arguing a point may very well be trying to convince himself as much as his opposition. ..

ISTP
from another source(personality pathways)

Rodin's Thinker is introverted. Here these thinkers ponder the apparent chaos of the world in order to extract from it the universal truths and principles that can be counted on. These principles, once extracted, will provide the logical structure on which to build strategies.

They have a finely nuanced ability to analyse situations, find root causes and foresee consequences. They distrust action taken too quickly without the necessary investigation. They are usually levelheaded, objective, impersonal yet intensely involved in problem solving. They are fiercely independent, seeking input and comments from a chosen few. When reporting to others, they need to establish credibility first: their own and that of the person they are reporting to. If the gap in knowledge and expertise is too great and their own proficiency dismissed, belittled or ignored, they will lose interest and motivation.

They are less interested in running the world as they are in understanding it. They are curious and capable of explaining complex political, economic or technological problems, taking great pleasure in explaining all the factors and intricacies. They are rigorous with their thoughts and analysis, choosing the exact words that convey precisely what is meant. They may spend a lot of time defining words, concepts and systems in order to define a problematic solution.

They are armchair detectives, scientists and philosophers, spending most of their time in quiet reflection to ponder truth, and solve mysteries. They may tend to neglect social requirements and responsibilities, finding many relationships to be too superficial to be of much interest.

ISTPs are equally difficult to understand in their need for personal space, which in turn has an impact on their relationships with others.

Communication also tends to be a key issue, since they generally express themselves non-verbally. When they do actually verbalize, ISTPs are masters of the one-liner, often showing flashes of humor in the most tense situations; this can result in their being seen as thick-skinned or tasteless.

Like most SPs, ISTPs may have trouble with rote and abstract classroom learning, which tend not to be good measures of their actual intelligence. They tend, sometimes with good reason, to be highly skeptical of its practical value...

They are at their best in a crisis, where their natural disregard for rules and authority structures allows them to focus on and tackle the emergency at hand in the most effective way.(ehem ehem, think batman!!!..or wolverine.. haha!)
