Introversion is a personality trait characterized by a focus on internal feelings rather than on external sources of stimulation. Introverts and extroverts are often viewed in terms of two extreme opposites, but the truth is that most people lie somewhere in the middle. Being an introvert can be difficult if you let it.
While introverts make up an estimated 25 to 40 percent of the population, there are still many misconceptions about this personality type. It is also important to note that introversion is not the same thing as social anxiety or shyness. Being an introvert does not mean that you are socially anxious or shy.
What is an introvert
Introversion is one of the major personality traits identified in many theories of personality.
People who are introverted tend to be inward turning, or focused more on internal thoughts, feelings and moods rather than seeking out external stimulation.
Introversion is generally viewed as existing as part of a continuum along with extroversion. Introversion indicates one end of the scale, while extroversion represents the other end.
The terms introversion and extroversion (also often spelled extraversion) were popularized through the work of Carl Jung and later became central parts of other prominent theories including the big 5 theory of personality.
The introversion-extroversion dimension is also one of the four areas identified by the Myers-Briggs Type Indicator (MBTI). According to many theories of personality, everyone has some degree of both introversion and extroversion. However, people often tend to lean one way or the other.
Introverts tend to be more quiet, reserved, and introspective. Unlike extroverts who gain energy from social interaction, introverts have to expend energy in social situations. After attending a party or spending time in a large group of people, introverts often feel a need to “recharge” by spending a period of time alone.1

Causes
In order to know why some people are introverted and some people are extroverted, it is important to understand the role that your body’s physiology plays. The way that your body responds to the outside environment plays a critical role in determining your level of extroversion and introversion.
The psychologist Hans Eysenck suggested that these arousal levels could be thought of as a continuum. According to his arousal theory of extroversion:
- 15 percent of people have a minimal set point, meaning they naturally have low arousal levels
- 15 percent of people have a high setpoint, meaning they naturally tend to be more aroused
- 70 percent of people lie somewhere in the middle of the continuum
