It’s occurred to me recently that there seem to be basically two different types of people: the sychronous and the asynchronous. Synchronous people like to have conversations; they want to deal with things “in the present,” then move onto other things. Asynchronous folks, on the other hand, want to correspond and have some time to think things over; at the extreme, they won’t use the telephone even for simple matters due to the risk of bothering someone when they’re otherwise disposed.

Then again, maybe these are just manifestations of the broader traits of extroversion and introversion; I suspect most introverts (like me) prefer email to phone calls and IMs, while most of the extroverts I know aren’t much for email—they might read it, but good luck getting a response amounting to more than one sentence. Of course, these days you can’t really be just one or the other—although I do long for a return of the days of the handwritten letter sometimes.

Heidi Bond is also thinking about synchronicity and the extroversion-introversion divide:

While I like all my friends very much, I don’t understand how interrupting a perfectly good train of thought with the annoyance of a call could be perceived as a benefit. And I think that about sums it up—calls, however dear the friend, are an annoyance.

And so I wonder whether there’s a difference between cell phone usage of extroverts and introverts.

Undoubtably. Of course, you could be an introvert like me, but be trained to carry your phone with you all the time, and reap the worst of both worlds.
