We are so used to categorizing our friends, family, and others around us as extroverts or introverts. That categorizing makes us think it helps us determine how we interact with a particular set of people, and what to expect in situations from them.
Psychology says that introverts tend to focus on one person at a time, while extroverts find it important to interact and engage with several people at a time. They excel in groups of people.
So, the common belief that extroverts are more successful is because of their better group interactions and better (perceived) social skills.
The bias is obvious, and most of us tend to incline ourselves to become extroverts (even when our natural nature is introverted). Because that’s what we think will make us successful.
The bias needs to fall. Not that all of us need to be introverts or all of us need to be extroverts. We need to be what we are.
When we acknowledge and understand that most of us are ambiverts (exuding a blend of traits from both extroverts and introverts), and stop judging others as one of two extremes, the bias collapses.
With the collapse comes the opportunity to reap the benefits. Benefits that come packaged separately in the form of extroverts, introverts, and ambiverts.
To extract true benefits make use of the true you, and the true others around you.
