In the Big Five personality traits model, individuals with low extraversion are considered introverted. These individuals generally prefer spending time alone over being in social settings or large groups. They value self-reflection and independent work, and they perform best in quiet and calm environments. People with low extraversion are cautious about new people and settings, preferring deep and narrow relationships.

Additionally, introverts tend to express their emotions less outwardly compared to extroverts, often keeping their thoughts and feelings internalized. They find value in enriching their inner world, and may be passionate about creative activities or independent learning. Having low extraversion means less participation in social activities, but this does not necessarily indicate a lack of social skills, rather it reflects a different preference for interactions.

Introverts are also characterized by their sensitivity to external stimuli, which can mean they easily become tired in noisy environments or with many social demands.
