There is a great deal of confusion between introversion and extraversion, especially on my part. I have realized that introversion and extraversion deals with more on how you perceive the world and how you get energized. It has almost nothing to do with how many friends you are and very little whether you like to go in public or stay at home. I know a lot of introverts that are outgoing and extraverts that like to relax at home.
For example an ISFj can be outgoing for the fact that is has as a secondary dominant function and that can be enough to make that person appear extraverted and not have problems talking to people and doing extraverted activities.
I believe that introverts use their second function to make them appear extraverted and extraverts also use their second function to make them appear introverted. What do you guys make of this?
