Introvert is formed from the prefix intro–, meaning “inwardly” or “within,” and the root vert, meaning “to turn” (as in invert). The concept of introversion and introverts (and other personality types) was popularized by psychologist Carl Jung in the early 1900s.
Causes of Introversion
Researchers have found that introverts have a higher blood flow to their frontal lobe than extroverts do. This part of the brain helps you remember things, solve problems, and plan ahead. Introvert brains also react differently to dopamine than extrovert brains do.
Etymology. From New Latin intrōvertere, from intro- (“within”) and vertere (“to turn”). Popularized as a psychological term by the German works of Carl Jung.
That means, although we can grow and change over time, we're born as either introverts or extroverts. And you can tell fairly early on—Laney says children begin to show signs of introversion or extroversion as early as four months of age.
Being asked to speak during a meeting, a surprise party or trip, or unexpectedly running into an acquaintance at the store can feel overwhelming to an introvert. Introverts may also experience more stress when they don't have time to decompress or recharge themselves with some alone time.
Introverts are easily distracted by external stimuli and while they might be too nice to say anything, get very frustrated with constant interruptions when they are trying to concentrate.
Independence. Unique and fiercely independent, introverts are more inclined to let their own inner resources guide them than follow the crowd. We do our best work — and are our happiest — when we have the freedom to explore ideas, spend time alone, and be self-directed and independent.
Yes, emotional trauma can cause a person to become a lot more introverted. Along with something as small as a loud noise more traumatic events can clearly change the way that someone acts.
Even though introverted people tend to prefer time alone, they can also experience feelings of loneliness.
Introversion and Happiness
While introverts are generally likely to report lower levels of happiness than extroverts, this does not mean that introverts are unhappy. Ultimately, it's important to note the happiness benefits of both introverted and extroverted behavior, no matter where you fall on the spectrum.
Extroverts may live longer than introverts – but not during a pandemic. A US study showed that extroverts had a slightly higher mortality rate than introverts during the first Covid-19 wave in the US. It remains to be seen whether this pattern continued into 2021 and 2022.
Cain's definition is that introverts have a preference for a quiet, more minimally stimulating environment. Introverts tend to enjoy quiet concentration, listen more than they talk, and think before they speak, and have a more circumspect and cautious approach to risk.
While introverts make up an estimated 25% to 40% of the population, there are still many misconceptions about this personality type. It is also important to note that being an introvert does not mean that you are socially anxious or shy.
Overall findings show introverts are more vulnerable than extraverts to depression and decreased mental well-being. Introverts are more likely to be compliant and have lower self-esteem than extraverts, and also have less social support than extraverts, which can be detrimental when experiencing depression.
You can't “turn” into an introvert or extrovert, just like a dog can't turn into a horse. However, you can, as an introvert, learn to manage your energy, develop confidence, and socialize in a way that works for you. Likewise, extroverts can learn the value of solitude and slowing down.
Introverts are usually better listeners.
The “quiet ones” really do tend to listen and consider the ideas and feelings of others. In conversation, they may take mental notes and focus intently on what the other person is trying to express — as opposed to simply waiting for their chance to speak.
Introverts struggle with the fast pace of many organizations and offices without walls can be rough for introverts who prefer to go inward to do their best thinking. If you're an introvert, you struggle with finding quiet time to gather your thoughts, particularly at brainstorming meetings.
Angry Introverts are in a sensitive state, and they can easily become overstimulated by too much social contact. Interestingly, Introverts won't usually respond to their anger by leaving altogether.
While it's true that both types of personality can experience problems with their mental health, it's widely accepted and proven that introverts are more susceptible to depression than many other personality types.
Big Crowds
Swarms of strangers can be a fear for many people for various reasons, but it is particularly common for anxious introverts. Introverts gather their energy from being alone, but that doesn't mean the “all alone in a crowd of people” thing always works.
Extroverts' brains run on an energy-spending nervous system, whereas introverts' brains run on an energy-conserving nervous system. This is why introverts feel content and energized when reading a book, thinking deeply, or diving into their rich inner world of ideas.
Although it's not a medical diagnosis, it is a valid experience that introverts and extroverts can face. It can be an emotional and physical response to social overstimulation that leaves you feeling drained and exhausted. You might feel physically tired, stressed, angry, or irritable.
Whether it's making small talk to the point of feeling drained or just having a busy day at work, life can be exhausting for both introverts and highly sensitive people. It's not unusual for them to feel quite tired and mentally fatigued at the end of the day, and they may even need more sleep than others.
On the contrary, introverts have attractive qualities because they're active listeners. They speak less and listen more, which gets people interested in them. What makes introverts attractive is their ability to observe beyond the words people speak. They pay close attention to details and are extremely prudent.
Because they are naturally very observant and thoughtful, introverts are also excellent listeners. Great leaders don't just talk, they listen intently — to their employees, consumers, and anyone else around them. They're vocal about their ideas but are also open to feedback and change.
