Final answer:
False, Carl Jung believed that while everyone has capacities for both extraversion and introversion, one typically becomes dominant. He also introduced the concept of the persona and emphasized the need for a balance between extraversion and introversion for self-realization.
Step-by-step explanation:
The statement is indeed false. Carl Jung postulated that while every individual has the capacity for both mental attitudes of extraversion and introversion, one of these typically becomes dominant in their personality. Extraverts are energized by social interactions and outward activities, whereas introverts gain energy from inner psychic activity and may prefer quiet or solitary environments. However, Jung did not believe that individuals are restricted to one orientation throughout their lives. Instead, he saw value in achieving a balance between the two, as this balance aids in the journey toward self-realization.
Jung also discussed the concept of the persona, which he considered a compromise between an individual's true self and societal expectations. The persona serves as a 'mask' that people consciously, yet partially unconsciously, create. It's how we present ourselves to the world, hiding parts of our nature that do not align with societal norms.
Jung's theories have had a significant impact on personality psychology, influencing various psychological tools, such as the Myers-Briggs Type Indicator (MBTI), which explores a person's degree of introversion vs. extraversion among other dimensions.
