Introversion/extroversion is probably the most well-known of the personality traits. It was first proposed by Carl Jung, the Swiss psychiatrist in the early 20thcentury  and since then, it has been central to practically every personality profile. However, despite its prominence, there is a great deal of misunderstanding and bias that surround it. You often hear that introversion means you are shy and lack confidence and extroversion means you are assertive and outgoing. You may believe that introverts are quiet and need to start speaking up if they are to get ahead, whereas extroverts don’t listen and just want to get their own way. The truth is far more fascinating.
