Was just watching Youtube video Veritassium about the non-existence of learning styles yesterday. I wonder if similar studies would show that there really are no introverts vs. extroverts in the sense that all people really have roughly the same need for human contact. Kind of like everyone needs physical activity, but some people gravitate more to it than others. Probably the wrong forum to voice such a theory...
And that anxieties, shyness, awkwardness are orthogonal to it. And that being loud dont imply extroversion either.
