Introversion
Introversion is a basic personality style characterized by a preference for the inner life of the mind over the outer world of other people. It is one of the Big Five dimensions that define all personalities—introversion sits on a continuum, and at the opposite end is extroversion. Compared with extroverts, introverts prefer subdued and solitary experiences.
Introverts do not fear or dislike others, and they are neither shy nor plagued by loneliness. A crowded cocktail party may be torture for introverts, but they enjoy one-on-one engagement in calm environments—more suited to the make-up of their nervous system. Evidence suggests that, unlike extroverts, introverted brains do not react strongly to viewing novel human faces; in such situations, they produce less dopamine, a neurotransmitter associated with reward.
How to Identify the Introvert
Carl Jung popularized the term introversion, and it suggests an inward orientation to one’s mental life rather than the outward orientation of extroverts to social life. Introverts gain energy from reflection and lose energy in social gatherings. Most people are neither purely introverted nor purely extroverted but display features of both—they are so-called ambiverts. Almost every person, for example, needs occasional solitude to replenish their energy.
Cultures differ in how they value certain personality traits, and America likes its extroverts; it rewards assertiveness and encourages people to speak up. Studies suggest that there are just as many introverts as extroverts, but they are less visible and certainly less noisy. First and foremost, introverts seek out and enjoy opportunities for reflection and solitude; they think better on their own. They feel drained by too much social interaction and are the first to leave a party. Even as children, they prefer to observe first and act later.
One clue that introverts are happy comes from studies showing they react differently to various stimuli than do extroverts. For example, introverts are more responsive to internally generated brain activity, from planning to remembering the past. They are content with their own thoughts and don’t need a steady stream of novelty and emotional arousal to experience pleasure; they prefer the quiet of calm to the high of happiness.
Introversion appears to be a personality trait, like all personality traits, influenced by genetics and environmental factors. Neuroimaging studies show different patterns of brain activation in introverts and extroverts, suggesting basic biological differences in brain circuit wiring. Nevertheless, studies show that introverts can learn to act more extroverted if they plan to change specific behaviors—maybe initiating a conversation with an acquaintance. Some evidence suggests that doing so increases well-being.
How Introversion Differs From Shyness
Introversion and shyness are different, even though both involve limited social interaction. The shy person wants to engage with others but fears doing so. They are highly self-conscious and easily inhibited by others. Many introverts socialize easily, but they strongly prefer to do so in very small groups or, sometimes, not at all.
Introversion is a positively healthy, if often misunderstood, way of negotiating the world. With a low threshold for small talk and superficialities, introverts enjoy conversations that are deep and meaningful. This can make them highly attuned to those they engage with. Notable introverts such as Albert Einstein and J.K. Rowling exemplify the creative edge that can come from strong engagement with one’s inner world.
Introverts excel as leaders by prioritizing their values and making analytical decisions that are independent of social validation. They influence others and lead them to important goals by quiet power rather than displays of ego. Introverts may do best by leading proactive people. Meanwhile, extroverted leaders may find such people threatening.
Introverts have a finite amount of social energy, and they tend to have one or two close friends rather than a large social circle. They prefer in-depth relationships to casual ones. Given this orientation, introverts risk being seen as not liking others or being labeled aloof or arrogant. They run the clinical risk of being seen as suffering from social phobia or even avoidant personality disorder when they are not.
There’s truth to the belief that opposites attract, and many marriages are happy introvert-extrovert pairings. But especially in novel social settings, introverts and extroverts are at risk of misunderstanding each other. As introverts struggle to monitor all the strands of conversation and may even be plotting an exit strategy, their quiet may be mistaken for engaged listening, which spurs extroverts to keep talking.
