All that is
society makes you want to pass as an extrovert
you do things to try to prove to yourself that you can bold and assertive.
subject to this bias that's very real in our society
the key to maximising our talents is to put ourselves in the zone of stimulation that is right for us. however a lot of our institution are designed for extroverts, and a lot of the new system of teaching holds that all productivity or creativity comes from an oddly gregarious place. the typical classroom nowadays has pods of desk of groups even maths and creative writing which you would think would depend on solo flights of thought, kids are expected to work as groups. The vast majority of teachers reportedly believe that the ideal students are extroverts.
Even in the office place, we now have open plan offices.
I think at this point it's important to say that I really like extroverts.
Carl Jung the psychologist who first popularised these terms says that people aren't strictly introvert and extroverts.
Solitude is an important ingredient to creativity
The insights of contemporary psychology - We can't even be in a group of people without mimicking the opinions of the people in the group. Groups famously follow the opinions of the most dominant and charismatic person in the room even though there is zero correlation between being the best talker and having the best ideas. So it's much better for everyone to go away by themselves generate their own ideas freed from the distortion of group dynamics.
We live with a value system that upholds the extrovert ideal. the universal belief that the ideal self is outgoing, alpha and comfortable in the spotlight. works well in teams and socilaises in groups.
if all this is true then why do we continue to have our schools and offices this way and make introverts feel guilty about wanting to be alone some of the time? One answer lies deep in our cultural history: One Western societies (particularly the USA) have always favoured the man of action over the man of contemplation. In america's early days we lived in what historians call a culture of character where we still at that point valued people for their inner selves and moral rectitude and if you look at the self help books from this era had titles like 'character: the grandest thing in the world' they featured role models like abe lincoln who was praised for being modest and unassuming. But then we hit the 20th and we enter a new culture which historians call the culture of personality - we evolved from an agricultural economy to a world of big business, suddenly people are moving from small towns to the city where instead of working alongside people they've known all their life, now they are having to prove themselves in a crowd of strangers so quite understandably, qualities like magnetism and charisma and assertiveness suddenly come to seem really important, and sure enough the self help books change to meet these new needs and they feature titles like 'how to win friends and influence people' So that's our cultural inheritance. Non of this is to say that social skills are unimportant.
