Today we will focus on the study of such a concept of psychology as a dichotomy. To begin with, this definition should be clarified. In a general sense, dichotomy is a special method of logical division. It consists in the fact that a divisible concept is divided into two incompatible ones. In another way, we can say that a dichotomy is the opposition of two parts of one whole. A similar term is widely used in science, which studies the interaction of the human psyche with the world around him. This discipline is called socionics. Let's take a closer look at this science and the role of dichotomy in it.
Division methods
Since the earliest times, people have said that either side has its opposite. Everywhere, relatively speaking, there is a dichotomy of good and evil. At the same time, light has long been opposed to darkness, the feminine to the masculine, life on earth to heavenly life, etc. The most common in socionics is the dichotomous Jung scale. It is with its help that sociological types are formed, which include about 16 objects. But a significant part of them can be divided in more than 30 different ways. Since ancient times, a dichotomy in psychology has been competing with trichotomy, a science with threefold division. In changing situations, it is customary to introduce an intermediate section between two extremes. It has long been proven that for coding information, as well as organizing division classifications, it is beneficial to use binary and triads. In general, we can say that we are talking about the division into even and odd, with their optimal combination with each other. The concept of double dichotomy is a division into four. This method is also widely studied in socionics, as is the logical separation itself. This method is used to highlight small groups, four classes in each. Let's consider them in more detail.

Commutative irrationals
Sociological types belonging to this category have a number of features. The understanding and worldview of the surrounding world in this class is concrete and as clear as possible, mostly close to reality. The world for people with this sociotype is like picking up mosaics. In other words, every detail is not thrown away, but can take any position. If we correlate this category of human psychology with the everyday plan, it can be argued that such people practically do not throw things away, but only shift them.
Distributional Rationalities
The difference between people with such a sociotype and commutative types is that the perception of the world is linear, as if through glasses of "ordered experience." That is, they bring certain objects to the forefront, pushing others that perform the function of the background. People with a distributive sociological type are the most difficult to endure a state of uncertainty. Since in this case, their fulcrum disappears, which allows them to distribute funds and forces for a specific purpose. But then people of this class are considered the most punctual and organized members of society. In their house you will not find a huge number of things, and those that are present are kept in strict order.
Associative irrationals
People with a similar psyche perceive the world through unconsciously generated images. That is, some detail of the overall picture evokes an ideal, holistic image in such a sociological type. The category of people belonging to this class always has a huge number of different ideas. But however, thoughts are practically not ordered and flow one into another.
Dissociative rationals
One can say about such people that any information coming from outside them, as it were, passes through the βprismβ of their worldview. That is, all information is divided into small particles from which they can create images of any complexity.
The scientific essence of the logical division method
Classical dichotomy includes a number of social divisions into 4, 8, 16, etc. Thanks to a combination of binary scales, you can create an object or model of any complexity. Socionic dichotomy has a distinctive feature - it is a recognition of the continuity and equivalence of both poles. For example, emotions usually suppress logical thinking, but at the same time they suggest its presence at another time and in another place. This proposition is reflected in the principle of equivalence from mathematics - strict equality. The creation of an explicit emphasis on one of the poles inevitably leads to a crazy compensating reaction of the polar principle. When suppressed intuitiveness makes itself known, a person develops fetishism, superstition, as well as wild prejudices in ideology.

Thus, a person pays for excessive sensory grounding. Conversely, when displacement of sensoryness occurs, perverse tastes and strange habits in the domestic sphere are manifested. So there is a payment for the painful intensity of intuitive conditions. Also in psychology there is a term - existential dichotomy. This concept is invariably present in the life of every person, differing only in the
types of culture and individual characteristics. An example is life and death - the main division. Summarizing all of the above, we can say that a dichotomy is, in fact, the principle of zero and one in a computer, which is globally used in modern computer technology.
