Question: What's the difference between extroversion and second-handedness? According to Wikipedia, extroversion is "the act, state, or habit of being predominantly concerned with and obtaining gratification from what is outside the self." A key distinction between introverts and extroverts is that extroverts mentally "recharge" by interacting with other people, while introverts do that by being alone. Does being an extrovert mean that you're second-handed? Is it a moral failing of any kind?
Question: Are "introversion" and "extroversion" valid as psychological types? Sometimes people classify themselves and others as "introverts" and "extroverts." What does that mean? Is the distinction valid and useful? Why or why not?
Summary: I answer question about whether an introvert should stop attempting to be more extroverted to meet new people. Then I discuss an example of a parent teaching a child to evade that I witnessed. Finally, I read a question on inheritance that I'll answer next week.
