I am a bad data point
When I was in my teens, I got my hands on one of the simplified Myers-Briggs tests. You may know the ones – they sort you out into things like ISFP and ESFJ and INTP and so on, by forcing you to chose between two different statements (80 times or so). Each question is focused on one of the four pairs: Introvert/Extrovert, Sensing/iNtuition, Feeling/Thinking, Perceiving/Judging. If you pick the Introvert statements more often than the Extrovert statements, well, you’re an Introvert, and so on for the other pairs.
The first time I took this, my result was: XNXX.
X, if it’s not obvious, means “too close to tell”.
If ambidextrous means I use both hands equally well …
Over the years, I’ve shifted a bit in my temperment type, but I’m still pretty solidly straddling that line between Extrovert and Introvert. Some days, I love social contacts and strike up conversations on a bus or in a grocery store or want to hit parties. Other days, I just want some time alone, doing my personal thing. Having a foot on both sides of the line, I’ve learned how to pull on those sides of myself when I need to – becoming a sort of “ambivert”.
When I don’t have to pull on one side or the other, it still would be really handy to easily let people know which side of the line I’m on for any given day. I suspect I’m not the only one, so I made a sign and some buttons and stuff: For the buttons and stuff, check it out on CafePress: http://www.cafepress.com/ambiverts.
