“statistics of myers-brigg show that 75% of population are extroverts”
The Myers-Briggs definitions of introvert and extrovert is different from the colloquial usages of the words. In MBTI, an introvert is one who thinks “internally” and an extrovert is one who thinks “externally”. For example, an MBTI extrovert is likely to be someone who talks through their thoughts. An MBTI introvert is one who is likely not to say anything until he has thought through the subject and solidified his ideas. if you put the two of them in the room together, the likely outcome is that the introvert will think to himself, “why can’t that guy be quiet so I can think”, and the extrovert will think to himself, “that guy just doesn’t have any useful ideas”.
In the colloquial sense, we mean socially introvert and extrovert, i.e. shy vs. outgoing. So MBTI isn’t really useful in this discussion.
