Architects need not be thought of as only interested in drawing blueprints for buildings or roads or bridges. They are the master designers of all kinds of theoretical systems, including school curricula, corporate strategies, and new technologies. For Architects, the world exists primarily to be analyzed, understood, explained - and re-designed. External reality in itself is unimportant, little more than raw material to be organized into structural models. What is important for Architects is that they grasp fundamental principles and natural laws, and that their designs are elegant, that is, efficient and coherent.
Architects are rare - maybe one percent of the population - and show the greatest precision in thought and speech of all the types. They tend to see distinctions and inconsistencies instantaneously, and can detect contradictions no matter when or where they were made. It is difficult for an Architect to listen to nonsense, even in a casual conversation, without pointing out the speaker's error. And in any serious discussion or debate Architects are devastating, their skill in framing arguments giving them an enormous advantage. Architects regard all discussions as a search for understanding, and believe their function is to eliminate inconsistencies, which can make communication with them an uncomfortable experience for many.
Ruthless pragmatists about ideas, and insatiably curious, Architects are driven to find the most efficient means to their ends, and they will learn in any manner and degree they can. They will listen to amateurs if their ideas are useful, and will ignore the experts if theirs are not. Authority derived from office, credential, or celebrity does not impress them. Architects are interested only in what make sense, and thus only statements that are consistent and coherent carry any weight with them.
Architects often seem difficult to know. They are inclined to be shy except with close friends, and their reserve is difficult to penetrate. Able to concentrate better than any other type, they prefer to work quietly at their computers or drafting tables, and often alone. Architects also become obsessed with analysis, and this can seem to shut others out. Once caught up in a thought process, Architects close off and persevere until they comprehend the issue in all its complexity. Architects prize intelligence, and with their grand desire to grasp the structure of the universe, they can seem arrogant and may show impatience with others who have less ability, or who are less driven.

INTP types are quiet, thoughtful, analytical individuals who tend to spend long periods of time on their own, working through problems and forming solutions. They are curious about systems and how things work. Consequently, they are frequently found in careers such as science, architecture, and law. INTPs tend to be less at ease in social situations or in the "caring professions," although they enjoy the company of those who share their interests. They also tend to be impatient with the bureaucracy, rigid hierarchies, and the politics prevalent in many professions. They prefer to work informally with others as equals.
INTPs organize their understanding of any topic by articulating principles, and they are especially drawn to theoretical constructs. Having articulated these principles for themselves, they can demonstrate remarkable skill in explaining complex ideas to others in simple terms, especially in writing. On the other hand, their ability to grasp complexity may also lead them to provide overly detailed explanations of "simple" ideas, and listeners may judge that the INTP makes things more difficult than they are. To the INTP, however, this is incomprehensible: They are merely presenting all the information.
Given their independent nature, INTPs may prefer working alone to leading or following in a group. During interactions with others, if INTPs are focused on gathering information, they may seem oblivious, aloof, or even rebellious—when in fact they are concentrating on listening and understanding. However, INTPs' extraverted intuition often gives them a quick wit, especially with language. They may defuse tension through comical observations and references. They can be charming, even in their quiet reserve, and are sometimes surprised by the high esteem in which their friends and colleagues hold them.
When INTPs feel insulted, however, they may respond with sudden, cutting criticism. After such an incident, INTPs are likely to be as bewildered as the recipient. They have broken the rules of debate and exposed their raw emotions. To INTPs, this is the crux of the problem: emotions must be dealt with logically—because improperly handled emotions, INTPs believe, can only harm.
