5 Telltale Introvert Characteristics & Traits, From Psychology Experts

All of us have some degree of introversion—but some, in particular, are true introverts through and through.

An introvert is a person who is high in introversion, a personality trait characterized by a tendency to be energized by alone time rather than socializing.

"Extroverts gain energy from social interaction, while introverts expend energy in social situations," explains relationship therapist Ken Page, LCSW. "After attending a party or spending time in a large group of people, they often feel a need to 'recharge' by spending time alone."

Introversion and extroversion exist on a spectrum, with some people falling toward the middle (aka "ambiverts") and others being true introverts or extroverts. Preferences toward introversion and extroversion were first popularized in the 1900s by famed psychiatrist Carl Jung, who considered this spectrum to be one of the foundational traits that influence our overall personality. Today the scale is part of many popular personality assessments, such as the "Big 5" and the MBTI.

Some research suggests that up to half of the population are introverts, though it's important to remember that it is a spectrum.

Many of us have the capacity to be introverted and extroverted at different moments and thus would qualify as ambiverts, falling somewhere in the middle of the spectrum.

According to Page, genetics plays a significant role in one's preference toward introversion versus extroversion. "In fact, of all the different personality traits," he says, "introversion and extroversion are one of the ones that are most strongly hereditary," he tells mbg, adding that environmental factors, such as how you were raised, will also come into play.

Our DNA also even determines the degree to which we can be flexible in these traits, he says. "Introversion and extroversion is really connected to a whole bunch of issues around our neurotransmitters, and the most important one is dopamine," he says.

Social introvert

There are a handful of different types of introverts, with one being social introverts, who prefer to spend time alone. As licensed psychotherapist Anthony Freire, LMHC, NCC, CCMHC, previously told mbg, "Social introverts are less interested in large gatherings or parties," adding that they don't avoid crowds because of anxiety but rather "where they feel the most comfortable and happy is either in complete solitude or in small groups in more subdued places."

Thinking introvert

There are also thinking introverts, characterized by a propensity to spend a lot of time thinking up in their own heads (and not necessarily voicing much). "The thinking introvert is very cognitive by nature. Often intellectual, this type of introvert is often at peace when studying, reading, learning, researching, and investigating," clinical psychologist Carla Marie Manly, Ph.D., previously explained to mbg. She adds that it wouldn't be uncommon for a thinking introvert to pause before speaking, as well, saying things like, "Let me think about that."

Anxious introvert

You may easily recognize an anxious introvert when you see one. According to Manly, they're often particularly quiet and can even seem on edge or nervous. For these folks, socializing may further stimulate the anxiety they feel, so they can tend toward an avoidant attachment style. She notes that this tendency to go inward may come across as rude or withdrawn, but it's really just a defense mechanism for protection.

Restrained introvert

Life is one big balancing act, and the same can be said for finding a balance of introversion and extroversion that works for you. Page says there will be times when you need to lean into more extroverted qualities, but ultimately, "When you feel the pull to go back into your inner world, try to follow that pull and respect it if you can."

He adds that your introverted self is a portal to a deep and rich understanding of the world that is uniquely yours, so take advantage of that. "There's a root level of reflection and depth that introverts hold that often can make them feel self-conscious, but those are some of the richest parts of them—what I call their 'core gifts,'" Page says.

While extroverts likely won't need as many boundaries in place in terms of socializing (because they want to socialize), introverts need to know how to hold firm boundaries with what they need.

Page explains that thriving as an introvert means not second-guessing yourself. For example, if you're really not feeling those dinner plans you made last week, the right people will understand that you need the alone time.

And last but not least (and somewhat related to the above point about boundaries), know your limits in terms of what you find draining. "People who were introverted also need to be very much aware of protecting themselves against overstimulation and burnout," Page says.

Introverts are people who tend to focus on their inner world rather than the external.

For these reserved and thoughtful individuals, understanding their own personality and inclination toward introversion can help them approach everything from work to relationships in a way that works for them.
