Extroverted Logic (Te)
Extroverted logic is an rational, extroverted, and dynamic IM element. It is also referred to as Te, P, algorithmic logic, practical logic, or black logic (because the symbol is black). Extroverted logic deals with the external activity of objects, i.e the how, what and where of events, activity or work, behaviour, algorithms, movement, and actions. The how, what and where of events would be the external activity of events, activity or work would be the external activity of a machine or individual(s) and algorithms describe the external activity of objects.
Since Te perceives objective, factual information outside the subject (external activity) and analyzes the rationale and functionality of what is happening or being done or said. "Quality" to a Te type is how well an object performs the functions for which it was made. A Te type can judge a person to be "effective" if he is able to achieve his purposes without wasting any energy or producing unwanted side effects. So Te types basically evaluate people and things using the same criteria.
Te as Leading Function
Extroverted logic as base function is manifested as a need to accumulate factual information, also from external sources such as books, second-hand information, etc, on matters of personal interest or of professional activity. This also gives these types confidence on being well-informed on the same matters, which enables them to enter arguments related to them with confidence on their knowledge, which may come across as arrogance to others. Another manifestation is an evaluation of external reality - work activities, world events, finances, procedures, personal relationships, conversations - from the point of view of factual accuracy and "making sense" and efficiency. It leads to an inclination to be proactive in increasing the efficiency and reasonableness of the external world, as well as a sense of self-worth connected on being involved and productive in activities seen as useful, profitable, or that increase one's knowledge base. To give out information that the individual knows not to be factually accurate is disturbing and avoided as much as possible.
Te as Creative Function
It is manifested as a preference for factual accuracy over ideological consistency, and for objective, "harsh" communication over careful words that avoid a negative atmosphere. A view of the external environment being efficient, reasonable, and making sense is essential to their well-being and sense of inner peace, but they do not feel a pressing need for being proactive or productive themselves in that area.
Te as Role Function
It is manifested as a need to appear efficient, productive and knowledgeable in their endeavours, as long as that does not conflict with priorities set up by their base function, extroverted feeling. For instance, they may end up defending a decision or action that is not the most efficient but it is the one they see as most desirable in order to achieve or maintain the emotional atmosphere they are aiming at (for instance, not be seen as hostile to a given person or group).
Te as Vulnerable Function
That is manifested as a skepticism and dislike for basing your beliefs, arguments, and actions on external sources of information. For instance, a SEI will rather trust the expertise of someone who seems to have hands-on experience, even if limited, than of someone who demonstrates to have read many books on the same subject. IEIs will base their opinions and views on their own personal insights and be, again, skeptical of "second-hand" factual information that contradicts it. "Don't trust everything you read" is a typical sneer of this function, especially when applied to sources of information otherwise seen as neutral and reliable, such as encyclopedias and handbooks. Another manifestation is a dislike for dealing with issues involving efficiency, productivity, and factual accuracy of statements made; statements are made according to input from other functions, not from double-checks against external facts which are seen as of lesser relevance to the issue at hand. Types with this function lack confidence in their ability to find relevant information in outside sources.
Te as Suggestive Function
The individual is attracted to people seen as knowledgeable, as well as truthful and willing to share that knowledge, in matters seen as interesting and useful to the individual towards achieving productivity and efficiency. Reliable information rather than the finished analysis is what attracts the individual; facts and explanations, not answers limited to the conclusions. For the same reason, the individual avoids people who are inclined to give out unreliable or simply untruthful information. The individual tends to neglect to think about the productivity of his actions and unconsciously relies on others to give him directions and advice about the best, most productive ways of doing things. He has difficulties measuring how much work he has done, whether it is sufficient, and how much it is actually worth. The individual admires people who are aware of the productivity of their actions and are always trying to do something rational and worthwhile.
Te as Mobilizing Function
The individual is keen on accumulating factual knowledge on subjects of personal interest and those that help him be more efficient and productive, but he's often unsure of his ability to find and select the correct information and is therefore attracted to people whom he sees as competent in that area and reassure him.
Te as Ignoring Function
The individual is adept at finding external sources of factual information and confident in his ability to evaluate their value, but regards collecting data as secondary to making them fit into a consistent logical system. To him, listing facts without analyzing their relationships is a trivial and boring exercise. He values efficiency and productivity but is skeptical that they will be achieved if one's actions and process do not follow a clear procedure.
Te as Demonstrative Function
The individual is adept at recognizing which aspects of an information, statement, or action are factually accurate in the sense of checking them against available external sources of information, but he tends to see this as lesser importance in comparison to their internal logical consistency when pursuing a concept fed by Ne or Se. To focus on the facts, also when giving out information, is seen as rather pointless when there is an Ne idea to be explored or a Se power to be gained.
