In the 16 Personalities test, the category that measures whether you prefer to be around others or alone is referred to as the "Extraversion (E) vs. Introversion (I)" dimension. This dimension assesses your social orientation and energy preferences.
Extraversion (E): People who score higher on the extraversion scale tend to be outgoing, sociable, and energized by interactions with others. They enjoy being in social settings, are often talkative, and feel recharged when surrounded by people.
Introversion (I): Individuals who score higher on the introversion scale are more reserved, prefer solitary or small group activities, and tend to find social interactions draining. They often need time alone to recharge and reflect.
No personality trait exists in isolation, and everyone falls on a spectrum between extraversion and introversion. The 16 Personalities test uses these dimensions as part of a broader framework to describe personality types.
