Keirsey uses a Jung-type model. Some of the mixes have names (and I think the types might to) but the types are often named by the letters (and less commonly by animals) SP (Monkey), SJ (Bear), NT (Owl), NF (Dolphin).
SPs (doers) are spontaneous, optimistic, charismatic, active, haptic/kinesthetic people. They make good actors, athletes, politicians (leaders of any kind), carpenters, mechanics...
SJs (planners) are very deliberate, purposeful, prompt, cautious, organized, protective, they are good at following directions and distrust what they don't have to work for. They make good soldiers, Accountants, parents, students...
NTs (thinkers) are very versatile and rational. They tend to think and be fairly even in terms of emotions. SJs and NTs would both be good at math, but SJs would follow formulas to the letter, NTs would solve math by using logic. They make good philosophers, engineers, scientists...
NFs (emotional) are typically kind and sensitive, intuitive. They are prone to negative emotions but partially because they allow themselves to be overwhelmed by sorrow in their lives, the lives of others or global problems. They make good writers, poets, artists, and "good" counselors... but would tend to bring their work home with them.
But your personality contains 4 pieces (Introverted/Extroverted, iNtuitive/Sensing, Thinking/Feeling, Judging/Perceiving) and that is where the letters come from. Based on your combination you could be an architect or guardian or mastermind or fieldmarshal or entertainer... it depends on your combination.
But I would refer to them as NT, NF, SJ or SP.

The theory that states delinquency is a function of personal predispositions such as temperament, personality, hormones, or genetics is known as the biosocial theory of crime. This theory examines the interaction between biological and social factors in influencing criminal behavior.

Galen's theory of the four temperaments (sanguine, choleric, melancholic, and phlegmatic) suggests that individuals have certain inherent qualities that influence their personality. By understanding one's dominant temperament, individuals can tailor their lifestyles to balance their natural inclinations. This can involve activities, behaviors, and environments that align with their temperament to promote well-being and a healthy personality.
The theory called the "third force" in personality theory is humanistic psychology. It focuses on understanding and studying the unique qualities and potential of individuals, such as self-actualization and personal growth. The main proponents of this theory were Abraham Maslow and Carl Rogers.
Well temperament and equal temperament are two tuning systems in music theory. Well temperament allows for each key to have its own unique sound quality, while equal temperament divides the octave into 12 equal intervals. Well temperament was used before equal temperament became popular, providing more variety in tonal colors, while equal temperament allows for easier modulation between keys but sacrifices some of the unique qualities of each key.

Theories such as the biological theory of personality suggest that important components of personality, such as temperament and traits, are influenced by genetic factors passed down from parents. Research on heritability estimates also supports the idea that genetic factors play a significant role in shaping aspects of personality. Twin studies and family studies have provided evidence that genetics contribute to the development of personality characteristics.
The theory of personality seeks to explain individual differences in behavior, thoughts, and emotions. There are various perspectives, such as psychodynamic (Freud), humanistic (Rogers), trait (Costa & McCrae), and social-cognitive (Bandura). These theories offer insight into how personality develops, the factors that influence it, and how it shapes our interactions and experiences.
The third force in personality theory is humanistic psychology. It emphasizes personal growth, free will, and self-actualization. It is considered less unified compared to other major approaches because it encompasses a variety of perspectives and ideas rather than a single overarching theory.
Biological theory of personality assumes that some of the personality traits are transferred through genes. However, there are those that are imposed on people from their surroundings.
