Carl Gustav Jung is known as an associate of the psychoanalytic school of Z. Freud and the founder of analytical psychology. In his research, he discovered that the process of forming the relationship "subject-object" is due to specific internal attitudes. In this regard, two main, opposite groups were identified.
Nature knows only two ways to preserve the vitality of the individual. In the first case, there is a fairly high fertility and a relatively low defense capacity of the organism. In the second, there is a variety of means of self-defense in an individual with relatively low fertility. If this biological law is applied to a person, then it turns out that one group is focused on objects and events of the external world, while the other directs most of its energy to creating subjective comfort. The analysis of these features allowed Jung to distinguish the extraverted and introverted types.
Extraverted psychological type
The extraverted attitude is characterized by a positive attitude towards the object. A person is constantly involved in ongoing events, dissolves in them entirely. Extroverted people are usually sociable, cheerful (if there is a cycle of events), they switch easily. But the seemingly high degree of adaptation has a downside. The attractiveness of the outside is detrimental to the inner world. This can manifest itself as incoherence, inability to concentrate, lack of punctuality and neglect of inner feelings and health.
Introverted psychological type
Introverts treat the world objectively in an abstracted way. They try to diminish its importance and create conditions for inner comfort. Any external event is viewed and evaluated through the prism of the subjective. These are people who love solitude, they are laconic among strangers, do not "get sick" with fashion trends, teachings, etc., do not show unnecessary activity. They have a rich inner world and special sensitivity. But the inability to assess objective reality makes them vulnerable.
