ENTP (extroversion, intuition, thinking, perception) is an abbreviation used in the publications of the Myers-Briggs Type Indicator (MBTI) to refer to one of sixteen personality types. The MBTI assessment was developed from the work of prominent psychiatrist Carl G. Jung in his book Psychological Types. Jung proposed a psychological typology based on the theories of cognitive functions that he developed through his clinical observations.
From Jung's work, others developed psychological typologies. Jungian personality assessments include the MBTI assessment, developed by Isabel Briggs Myers and Katharine Cook Briggs, and the Keirsey Temperament Sorter, developed by David Keirsey. Keirsey referred to ENTPs as Inventors, one of the four types belonging to the temperament he called the Rationals. ENTPs account for about 2–5% of the population.
By using their preference in each of these areas, people develop what Jung and Myers called psychological type. This underlying personality pattern results from the dynamic interaction of their four preferences, in conjunction with environmental influences and their own individual tendencies. People are likely to develop behaviors, skills, and attitudes based on their particular type. Each personality type has its own potential strengths as well as areas that offer opportunities for growth.
The MBTI tool consists of multiple choice questions that sort respondents on the basis of the four "dichotomies" (pairs of psychological opposites). Sixteen different outcomes are possible, each identified by its own four-letter code, referred to by initial letters. (N is used for iNtuition, since I is used for Introversion). The MBTI is approximately 75% accurate according to its own manual.
The ENTP has been described variously as the innovator, the originator, the lawyer, the inventor, the explorer, and the visionary. ENTPs also fall into the general categories of thinkers, rationals, and engineers.
Using their primary function-attitude of extraverted intuition (Ne), ENTPs are quick to see complex interrelationships between people, things, and ideas. These interrelationships are analyzed in profound detail through the ENTPs auxiliary function, introverted thinking (Ti). The result is an in-depth understanding of the way things and relationships work, and how they can be improved. To the ENTP, competence and intelligence are particularly prized, both in themselves and in other people.
ENTPs are frequently described as clever, cerebrally and verbally quick, enthusiastic, outgoing, innovative, flexible, loyal, and resourceful. ENTPs are motivated by a desire to understand and improve the world they live in. They are usually accurate in sizing up a situation. They may have a perverse sense of humor and sometimes play devil's advocate, which can create misunderstandings with friends, coworkers, and family. ENTPs are ingenious and adept at directing relationships between means and ends. ENTPs devise fresh, unexpected solutions to difficult problems. However, they are less interested in generating and following through with detailed plans than in generating ideas and possibilities. In a team environment, ENTPs are most effective in a role where they can draw on their abilities to offer deep understanding, a high degree of flexibility, and innovative solutions to problems. The ENTP regards a comment like "it can't be done" as a personal challenge, and, if properly motivated, will spare no effort to discover a solution.
A ENTP could consider everything above to be only ones personal interpretation. 
Inventors are introspective, pragmatic, informative, and expressive. They can become highly skilled in functional engineering and invention. Of all the role variants, Inventors are the most resistant to doing things a certain way just because it was done that way in the past. Intensely curious, Inventors are always looking for new projects to work on, and they have an entrepreneurial character. Designing and improving mechanisms and products is a constant goal of Inventors.
Though full of ideas, Inventors are primarily interested in those that can be put into action or used to make products. For example, they see product design as a means to an end, the goal being a marketable prototype. When beginning a project, they rarely start with a blueprint. Rather they are confident in their ability to find effective and pragmatic solutions during the design process.
Inventors tend to be laid back, nonjudgmental, and good conversationalists. They are often nonconformists who attract a circle of friends interested in their ideas or activities. Generally informative rather than directive in their social exchanges, Inventors are often able to explain their own complicated ideas well, and to comprehend the complex ideas of others. In arguments they may use debating skills, often to the significant disadvantage of their opponent. This strategy can backfire, however, by alienating those seeking a cooperative relationship rather than a combative one.
Inventors are usually ingenious individuals who are capable of rising to meet the demands of challenging situations. In work, they tend to be good leaders of pilot products that test their abilities. Constantly looking for new ways to do things, Inventors usually have the drive and the social skills to implement their ideas.
Drawing upon Jungian theory, Isabel Myers proposed that for each personality type, the cognitive functions (sensing, intuition, thinking, and feeling) form a hierarchy. This hierarchy represents the person's default pattern of behavior.
The Dominant function is the personality type's preferred role, the one they feel most comfortable with. The secondary Auxiliary function serves to support and expand on the Dominant function. If the Dominant is an information gathering function (sensing or intuition), the Auxiliary is a decision making function (thinking or feeling), and vice versa. The Tertiary function is less developed than the Dominant and Auxiliary, but it matures over time, rounding out the person's abilities. The Inferior function is the personality type's Achilles's heel. This is the function they are least comfortable with. Like the Tertiary, the Inferior function strengthens with maturity.
Jung and Myers considered the attitude of the Auxiliary, Tertiary, and Inferior functions to be the opposite of the Dominant. In this interpretation, if the Dominant function is extraverted, then the other three are introverted, and vice versa. However, many modern practitioners hold that the attitude of the Tertiary function is the same as the Dominant. Using the more modern interpretation, the cognitive functions of the ENTP are as follows:
Ne finds and interprets hidden meanings. This intuitive play weaves together insights and experiences from various sources to find the whole, which can then become a catalyst to action. Ne allows the ENTP effortlessly to identify complex interrelationships between ideas, people, and things that are often invisible to most other personality types.
Ti seeks precision, such as the exact word to express an idea. It notices the minute distinctions that define the essence of things, then analyzes and classifies them. Ti examines all sides of an issue, looking to solve problems while minimizing effort and risk. It uses models to root out logical inconsistency. In the ENTP, Ti analyzes the constant stream of information that Ne provides. Ti develops structure and reconciles any inconsistencies in the ENTP's belief system. However, Ti cannot match the activity of Ne, which leads the ENTP to juggle multiple projects and theoretical enterprises at any given time, in various stages of completion.
Fe seeks social connections and creates harmonious interactions through polite, considerate, and appropriate behavior. Fe responds to the explicit (and implicit) wants of others, and may even create an internal conflict between the subject’s own needs and the desire to meet the needs of others. When Fe is well developed, the ENTP can foster goodwill in others, and can be seen as quite charming and loyal. When it is not well developed, the ENTP can be seen as aloof and unconcerned with other people's feelings. In most ENTPs, weakness of the tertiary function can be observed in its inconsistency or lack of endurance.
Si collects data in the present moment and compares it with past experiences, a process that sometimes evokes the feelings associated with memory, as if the subject were reliving it. Seeking to protect what is familiar, Si draws upon history to form goals and expectations about what will happen in the future. Si offsets the ENTP's natural tendency toward anarchy and non-conformity. It acts as a sort of gravitational pull that keeps the ENTP in orbit around reality. Without this function, the ENTP can be seen as unpredictable and random, but when it is well developed, the ENTP is seen as orderly and understandable.
Later personality researchers  added four additional functions to the descending hierarchy, the so-called "shadow" functions to which the individual is not naturally inclined but which can emerge when the person is under stress. The shadow processes "operate more on the boundaries of our awareness…We usually experience these processes in a negative way, yet when we are open to them, they can be quite positive." For the ENTP these shadow functions are (in order):
