Ask HN: How do you measure your level of extraversion or introversion?

3 points by Goladus ↗ HN
I often see people assign themselves to one category or the other with great confidence, and I wonder how they know. Have you used an online quiz, have you worked with a professional, or do you "just know"?

I think most people just consider themselves as one or the other generally. I'm extremely talkative and outgoing, and always have been the type to engage with others. Growing up, majority of my report cards from elementary school use to say something like, "does a great job but talks too much" LOL. It's hard to ever consider myself introverted given how extreme my personality is.
Humans have a "reserve" of willpower which can be depleted. This is science; I can't find the study right now but here's an article about it? http://www.nytimes.com/2008/04/02/opinion/02aamodt.html

Now, consider actions which you take. Assign actions to depleting or filling up your store of willpower.

Do you find that various forms of social activity deplete or refill your store of willpower? If all the social activities you can think of deplete it, then you can safely assign yourself the introvert category.

Anyway, I'm not actually sure that this exercise is valuable. it seems like you might rather keep your identity small (see PG essay on the topic), as it can only constrain you.

There are some studies which contradict the "limited reserve of willpower" theory. I read about one just the other day which found that an increased need to urinate correlated with greater mental focus, whereas the limited reserve theory would suggest the opposite.
I'd think that having to urinate could lead to greater short-term focus by increasing the rate at which we're able to draw our willpower reserve. This explains the old "stay hungry" advice given to boxers, for example. I find I can concentrate better when I'm slightly uncomfortable, but I doubt I could maintain that level of concentration for a long period of time.
People have levels of both introversion and extroversion, most people have a balance between the 2, some people are extreme one way of the spectrum but can't be full one way. The exact balance within yourself is hard to measure but probably you know best where you can find yourself on the spectrum. Example, I am more introverted than extroverted, I like to be alone but do not mind to be among people either, I am not shy and able to start conversations with total strangers, but I really dislike being in groups and having to do the group thing as I think groups are mostly behaving dumb and retarded.
Surprised no one mentioned this yet - go look up Myers-Briggs. It's a personality test that gives you a type indicator... very useful for entrepreneurs to know your type and your co-founder's type etc. It deals with extraversion/intraversion and also thinks like sensing vs. thinking.
