Ignorance: Introversion and Extroversion:

Most people have heard of introversion and extroversion, terms first popularized by Carl Jung, either from their early years from teachers, counselors, or psychologists.  The problem with said terms is that most people don't seem to truly understand what they mean.  The term extroversion is typically used for those who are more outgoing, social, and interested in group activities.  Conversely, the term introversion is typically used for those who are more reserved and solitary.  At a basic level, those definitions are certainly true...  But people use them as an excuse to either judge people for being introverts, or brush off their lack of social skills as just part of their personality, rather than a skill-set that was hindered during early development.

Extroverts are those who more easily join group activities, and think more about other individuals' reactions than those that are introverted.  Introverts are far more absorbed in their own thoughts and plans than in group activities, but they're generally more concerned with being satisfied with their projects personally than with the reaction of others to them.  However, conversely, extroverts tend to be easily able to shrug off rejection and move on to another to show their projects when they have them, while those that are introverted tend to be crushed by rejection and negative reactions, slaving over their projects to find out why someone else didn't enjoy it as much as they did.

The one key thing people tend to be ignorant about is that having extroversion and introversion does not prevent one from gaining social skills if developed at a young age, and that introverts tend to be focused with the details, while extroverts tend to be focused on the outward appearance of general performance.  Additionally, some people are both, but have introversion about one subject while having extroversion about another.  No two people are alike, and no two personalities are the same either.
