The Shy Extrovert
When someone's shy, we often assume they're introverted. Shyness often does go along with introversion–but not always. Some people who get anxious among strangers actually love being around others–whereas true introverts find people exhausting. Like other shy people, shy introverts are routinely misunderstood as cold, aloof, or stuck-up. They're particularly likely to be judged negatively if they're also attractive, says Bernie Carducci, a psychologist at Indiana University.
The Fix: Directly challenge the mistakes you know people make, saying, "If I seem unfriendly, it's not because I don't like you, it's because I'm shy," or, "I had a great time hanging out with you." If that's too much for you, say it via email.
The Bubbly Introvert
When people come across as vivacious, exuberant, and cheerful, we assume they're extroverts. But some lively people are actually gasping for time to themselves. Having good social skills isn't the same thing as wanting to be around people all the time. "These things go together a lot," says Sanjay Srivastava, a psychologist at the University of Oregon. "But they're not perfect correlations."
