Other typologies

One of the world's most popular personality typologies, developed by Katharine Briggs and Isabel Myers on the basis of Carl Jung's ideas. Uses four dichotomies to determine the type.

The MBTI (Myers-Briggs Type Indicator) is a psychological assessment system that classifies people into 16 personality types along four scales: extraversion/introversion (E/I), sensing/intuition (S/N), thinking/feeling (T/F) and judging/perceiving (J/P). Each type is denoted by a four-letter code — INFP or ENTP, for example. The MBTI is widely used in business, education, career guidance and coaching around the world. The instrument has decades of practical application in the corporate environment: team-building training, recruitment, leadership development — everywhere the MBTI serves as a working tool. The scientific community, however, views the MBTI with reservations: critics point to the test's insufficient validity and low test-retest reliability (a person may get different types on repeat attempts).

A typology created by Alexander Afanasyev that describes personality through the ordering of four psychic functions: Emotion, Logic, Physics and Will. Each function occupies one of four positions in the hierarchy.

A typology describing a person's system of inner priorities through the distribution of four spheres — Will, Logic, Emotion and Physics — across four positions. Developed by Alexander Afanasyev, the system focuses on how much energy a person is willing to invest in different aspects of life. A function's position (first, second, third or fourth) determines the degree of confidence, the need for dialogue and the vulnerability in the corresponding sphere. Unlike an assessment of objective abilities, psychosophy describes precisely the attitude to the process and to the expected result. The combination of the four aspects forms 24 types, helping explore the sources of inner conflicts and the peculiarities of pair interaction.

A typology developed to describe the levels of a person's abstract thinking. It distinguishes levels characterising the ability to operate with abstractions of varying complexity — from concrete-situational thinking to metasystem analysis.

Yakov Feldman's model describing 8 stages in the development of cognitive complexity, from perceiving concrete objects to operating with global universals. The theory views the evolution of human thinking as a sequence of transitions between levels of abstraction. Each new stage (Object, Relation, Algorithm, System, Parameter, Principle, Paradox, Infinity) extends the intellect's capacity to grasp more complex structures. A person can use different levels depending on the task at hand, but usually gravitates towards a dominant range, which ultimately defines their problem-solving style and way of analysing data.

A typology describing four ways of perceiving and experiencing time. It shows how a person structures their attitude to the past, the present and the future — the form of thinking rather than its content.

A concept studying a person's individual relationship with time through the prioritisation of the Past, the Present, the Future and Eternity. Temporistics distinguishes four fundamental vectors of attention that determine how a personality adapts to change and finds its place in the world. Distributing these dimensions across four positions (from the most confident to the most passive) yields 24 types. The approach helps understand where a person draws motivation, where their existential anxiety hides, and how they perceive their own life path.

A personality typology describing 9 types, each defined by a deep motive — a basic fear and a basic desire. It focuses on the driving forces of behaviour rather than on outward manifestations.

The Enneagram is a typology whose roots go back to spiritual traditions (Sufism, early Christianity), while its modern version was developed in the 20th century by Oscar Ichazo and Claudio Naranjo. Unlike most Western typologies, the Enneagram concentrates not on how a person appears from the outside but on what drives them from within. Each of the nine types is governed by a particular emotional attitude (passion) and defence mechanism. An important feature of the Enneagram is its dynamics: under stress or in security the type can “shift” towards other types, displaying their qualities. In addition, each type has three subtypes (instinctual variants): self-preservation, social and one-to-one (sexual). The Enneagram is popular in psychotherapy, coaching and personal-growth work because it gives clear reference points for development and for overcoming limiting patterns.

The personality model of academic psychology, describing five fundamental traits: openness to experience, conscientiousness, extraversion, agreeableness and neuroticism. It is the most scientifically substantiated model of personality.

The Big Five (also known as the OCEAN model or FFM — Five Factor Model) is the result of decades of research by psychologists using factor analysis to uncover the basic dimensions of personality. Unlike socionics and the MBTI, which divide people into discrete types, the Big Five treats each trait as a continuum: a person can sit at any point of the spectrum from low to high. The five factors are openness to experience, conscientiousness, extraversion, agreeableness and neuroticism (emotional instability). Each factor consists of six narrower facets, giving a detailed picture of the personality. The model has been validated in hundreds of cross-cultural studies and predicts academic performance, professional achievement, marital satisfaction and even life expectancy.
