A friend tweeted about this issue few hours ago.

I always thought I'm an introvert but from these online tests (which might not reflect the real thing anyway) I'd taken... I don't know what to think. But it seems possible for conversions to happen. Or maybe I'm both?

OkCupid.com's "The Introvert/Extrovert Test"

Got this :

Introvert Extrovert
You're a quiet person, but not too quiet. You like your own company at times, but don't mind the company of others. Ideally, a few people is better than a lot in most situations. You'd be well suited to living in a small town and can easily handle living on your own. You know how to have a good time, but also know how to enjoy a good book. While a night on the town can be enjoyed, you don't like to go out all the time. One can get too much of a good thing. You can be irritated by extroverts sometimes. Especially if they talk a lot about non-consequential things or other people. You can sometimes be misunderstood for being grumpy and some extroverts find you a little aloof. You're probably relatively happy in who you are although something can always be improved upon.

(They have other possible results 'extrovert', 'quietly extroverted', and 'very introverted'.)

Funtestiq's "Introvert or Extrovert?"

I think this one had some good questions but there's not much explanation on the result.

Your score on this Introvert/Extrovert test is 18,
which means that you are more on the Introvert side.
