Introverted Logic according to Aushra Augustinavichiute

The feelings that arise when two objects are being compared based on some objective property, e.g. a sense of distance, weight, volume, value, strength or quality, we classify as logical. These are the feelings of objective evaluation; in certain cases this evaluation contributes to either activation or passivation of the person experiencing said feelings.

One perceives direct information that is obtained through the first signal system as a sense of proportionality or disproportionality of the objects, a sense of balance or imbalance between them, and a sense of understanding or not understanding the advantages one object has over the other. This includes all feelings that arise from objects and phenomena being known or unknown: curiosity, respect, fear, a sense of something being logical or illogical, a sense of power or powerlessness over a certain object.

All of these feelings we will call “logical”. Together they form an individual’s sense of logic. The degree of development of this sense of logic varies from person to person.

Logical feelings convey information related to whether or not the objects are known, whether or not they are in equilibrium, and whether or not they are comparable. They also carry information about the space and the position of the object within it.

Logical feelings are objective because they only take into account the ratio of objective properties rather than one’s own interests and needs. This aspect of perception determines one’s ability or inability to see objective, logical relations between the objects or their components.

When this aspect of perception is in the leading position, the individual is notably logical in their assessment of the interrelations in the objective static world, or world of objects. They have an ability to alter the relations between the properties of different objects, changing these relations in a desired direction. By doing this they are also able to impact the objects possessing said properties. Their accurate assessment of their own relations with other objects lets them know which objects should be avoided and which can be “hunted”.

An individual with this type of IM has an ability to set their logic (i.e. their cognition of the objective world and of its regularities and proportions) in opposition to the knowledge of others. They can shape and improve their own and other people’s cognition of the objective world. This gives them a sense of power when faced with the logic or illogicality of others.[1]

Introverted Logic according to WSS

Aspect: Structures and axioms. Any data set can be found to have underlying norms and rules that seem fundamental to it. Distinct elements of a set can be shown to have qualities in common, which based on membership to a set, can be generalised categorically. Furthermore, all propositions in a system must be consistent to all be true. Consequently, structures can be formulated to reduce complex data to a finite set of rules, making sense of the available information, with fundamental axioms necessitating or negating contingent propositions.

Metabolism: The individual identifies regularities and norms in their data, formulating models with finite rules to explain what is necessitated and what is not permitted. Such systems are designed with consistency, accounting for what fits together without contradiction. Similarly, order is brought to chaotic situations through the imposition of rules with consequences, communicating the parameters by which certain actions are unlawful or obligated, and classifying available data into different kinds and varieties so as to aid comprehension of what things are and how they differ.

Strength: The person is good at making sense of their thoughts and of the things around them, being able to formulate a clear rationale for their positions. Similarly, they will be able to disperse confusion by creating categories that best divide up the available data. The person will be associated with refined precision and clarity of thought, quickly spotting what is consistent with what they already know and highlighting any contradictions. In this way, they may come across as highly logical, easily spotting breaches of rules and subtle distinctions between two points of view.

Value: The person seeks to understand the world around them in a consistent, coherent manner. Desiring clarity and for things to make perfect sense, they look for signal in the noise of data, arranging them in a way that fits together neatly, providing them with a framework to account for new scenarios. The person will appreciate rules that can apply without exception, reducing chaos and confusion. As such, they will tend to create or follow a particular ideology or theory through which events are interpreted to fit together, and will much prefer when things align well under that lens.[2]

Introverted Logic according to SHS

Creating schemes, constructing, analysing; following laws, instructions, plans; keeping composure, emotional control; skeleton, bones.


The L-state means the construction of schemes, structures, and classifications. This kind of logic aims not at efficiency or profitability, but at the correctness and conformity to proportions. While thinking in the L-state, a person compares one object with another according to one or another criterion and places the object in a corresponding box on the classification table. L-thinking manifests as a short, extremely concise formulation and definition. The law of structural and logical thinking is to use minimum vocabulary (meaningful words) and maximum grammar (service words such as prepositions, conjunctions, particles, introductory turns).


The long-held L-state leads to an informal role in a team that is called a systematizer or an expert. They make objective, disinterested judgments on any issues of life. A person in the L-state is prone to isolation within a group, so that they could act according to the written and unwritten norms and rules that exist within the group. The second side of the L-role is to be a judge. Such a person is valued for their maximum non-involvement, so that they could soberly rule on various controversial cases.


A person in the L-state is characterised by coolness and indifference. In this state, there are no feelings shown or subjective preferences given. Figuratively, this state can be likened to a block of cold ice or a geometric regularity of a crystal or some mineral. This is the least psychological state, since it has absolutely no soul, no human warmth. But, on the other hand, it is the most balanced and stable state. This is a state of obedience, diligence, and discipline.


A person in the L-state is characterised by an almost complete absence of manifestations of “life.” Their facial expression is still like a statue, the body is straight and fixed, the eyes are dull and expressionless. Body movements are kept to a minimum. The rule “one body part–one function” is observed, that is, they only pick up objects with their hands, walk on their feet, and eat with their mouths. Operations are performed pointedly and discretely, with a noticeable pause at the beginning and the end of the motion.[3]
