When the focus is on social scenes and types of people, we want to know what to expect. Included in this is, how many of us are introverts vs. extroverts? Today I have read from 5 different sources, 5 different percentages.
In an article written in the past few months on the introvert and networking, the author says "about 70% of us are extroverts, I think". In another source I read 51% or more of us are introverts. In a researched paper I saw that in the US we have shifted from 30% introversion in the 1960's to about 68% introversion today.
What does this all mean? (aside from where are these percentages coming from and why are they so disparate?)
