That is hilarious that you said that extroverts may seem smarter. I agree for the most part, but boy, have I been wrong before! Boasting or bossing or being obnoxious as a natural personality trait is very unintelligent in my opinion. As an introvert, I have learned to get to know people at a slower rate, by listening instead of asking, or interrogating rather, and I feel like I have gained more trust and respect from others for it. Good luck with all future endeavors!
