Yeah, I can talk the hind leg off a mule. I don’t know how I can do that, but that’s what I’ve been told!
I have some pretty extreme variance in my chattiness. I’ll yammer on constantly under some circumstances, then in others I’ll be completely silent. I’m comfortable with both.
I don’t think the OP is talking about introverts/extroverts but about chatty versus non-chatty people. They aren’t the same set.
The absolutely must-read essay on the subject is here. It dates to 2003, but still crops up on The Atlantic’s recent most popular articles list fairly often.
Dunnow, the few times I’ve been in the company of an introvert that didn’t realize when to shut up it was someone who’d latched onto his personal obsession and that personal obsession wasn’t anything “social”. An extrovert who’s chatty does not tell other people to smile, or to go out more often, or to be more sociable, or to be more fashionable… extroverts bloody well do (note that this doesn’t mean “all extroverts do”, it means that people who do it are, IME, always extroverts). It’s the extrovert version of “assuming by default that other people are similar to me”; since introverts are rarer, they’re likely to get the message that “not everybody is similar to me” at a younger age.
I’m an extroverted introvert, if that makes sense, and I know what you mean. The attitude of STFU comes in loooooud and clear. Also, a lot of introverts will have a hostile attitude towards chatty people that makes it clear they feel the extroverts are bubbly and airheaded just because they prefer talking. There’s an air of superiority.
Trust me, I work in IT; I’ve seen this a lot.
