The Rational temperament is one of the four temperaments defined by David Keirsey.
Correlating with the NT (intuitive–thinking) Myers-Briggs types, the Rational temperament comprises the following role variants (listed with their correlated Myers-Briggs types): Architect (INTP), Fieldmarshal (ENTJ), Inventor (ENTP), and The Mastermind (INTJ).
Social roles: In romantic relationships, Rationals want a mindmate with whom they can discuss the topics that interest them, which are often abstract or theoretical, such as philosophy.As parents, they encourage their children to become self-reliant individuals capable of thinking for themselves.In their professional and social lives, Rationals are visionary leaders, developing and consolidating coherent long-term plans.The informative Rationals (Architects and Inventors) prefer theorizing, designing, and prototyping their ideas, which may cause them to feel overburdened when called upon to finalize their ideas into practical operation by themselves.Although Rationals are realistic, the abstract world serves as a tool for thinking independently and developing new ideas that can be used in more practical matters.
Rationals are unconventional thinkers when deciding on a task or solving a problem.Values: Rationals appear calm even in times of turmoil.They achieve this state through an intense concentration of effort rather than through cold-heartedness. They are knowledge-seekers who aspire to technical wizardry, and so are pleased when others defer to their expertise.Individualistic by nature, Rationals observe their own interests as a response to action, free from societal conformity or traditional thinking.Rationals are not necessarily uncooperative, but they will refuse to perform a certain action if it goes against their understanding or experience and is not based on sound logic or the facts (as they understand them) in a given context.Driven to excel, they work hard to achieve their goals, and they do well where they can take control or work independently on a task.
