Ever since extraversion was popularized by Carl Jung, founder of analytical psychology, it was generally assumed that the spectrum consisted of mainly extroverts and introverts. The majority of people do not know there is a third personality type that sits right in between the two; ambiverts. Like extroverts, ambiverts are comfortable with people, but similar to introverts, ambiverts also relish being alone. This hybrid of characteristics may have given ambiverts an edge in a study by The Wharton School, University of Pennsylvania.
I am totally an ambivert!
