Ok, two things here.

I always wonder about the Myers-Briggs test. I'm not entirely sure of the uses of it, but I think it's very interesting. I've heard it equated to "scientific astrology" and in some sense it does feel that way--though it makes no claims to tell you about your future or predict fortunes or any of that nonsense.

I guess my question is, what is the purpose of the test and does it fulfill whatever purpose that is well?

Second, just for fun, what's your personality type? I'm curious to see if skeptics score similarly.

I found this test on the internet, I'm not sure how good it is though:

I suggest if you want a better idea, browse the internet for one that seems more thorough.

I've been administered the myers-briggs test twice in a full on pen and paper two hour test fashion. My first attempt got me INTP and my more recent test got me INTJ.

Now, having read both of them, INTJ is so accurate it is really disconcerting. I fit into some sort of a category almost perfectly.

Supposedly INTJ's are only 1% of the population--will my fellow skeptics score a similar personality type? Post your results!

Edit: Using the link I gave above I scored INTJ again with the following preferences:

Introverted 89%    Intuitive 50%   Thinking 75%   Judging 100%

Hey thanks. I did a search for the topic, but I think I must have spelled "Myers" wrong. :x Oh well.

For what it's worth? INTJ - tested several times by different testers. Always INTJ.

So, if your categorization as an INTJ is 'so accurate it is really disconcerting' and you fit 'almost perfectly', then explain how it is possible at all that you could have been categorized an INTP the first time?!

I've done it several times and gotten a different letter set each time. Same goes with the enneagramme.

It's astrology without the sidereal mathematics and, like astrology, relies on confirmation bias. It also depends in large part on the simple truth that most people will only read their 'own' entry and not the others. Read all the summations for each zodiacal type and all the Meyer's letter combos. Unless you are a psycho, schizoid or  have BPT, they all apply to everyone.

I tested INTP when I was in 9th grade. So, what was I... 14 or 15? I didn't think it was accurate at the time. I have also read through the other personality types and none of them seem to fit nearly as well.

I am aware that it can be very general--much like astrology. However, I am giving input to the testing program. I imagine that this is why it's so accurate--it's basing its output on my input, but only somewhat repackaged.

Edit: For clarity, I'm 20 right now. So my other test was 5-6 years ago.

Either it's accurate or it isn't. It's zero-sum. "General" and "accurate" are antithetical terms. Carpet bombing may sometimes hit a target but one wouldn't categorize it as accurate. Likewise with Astrology, Meyers and Nuclear War.

Close only counts in horseshoes and hand grenades?

Nonsense, false dichotomy.  There are degrees of accuracy.

I started taking that test... and it just reeked of BS to me. How can you categorize someone's personality by asking them to make judgments about themself? There's no possible way that can be accurate- the way you perceive yourself may be completely different than the way you actually are, or at least the way you compare to the rest of the populace.

The only way this test *might* work is if someone were to observe your actions without you knowing. The observer could then make unbiased critiques of your actions, and possibly fit you into some subset... but the whole thing still looks like a load of poo.

Regardless, what is the point of trying to fit yourself into some sort of category? I think you'll agree that no two people on earth are identical in every way- so if the question list in a properly formatted test were long enough, you could eventually get down to a category that contains you, and only you. ...so what's the point? Why is it relevant to anything to say "oh, I belong in this personality subset"?

Rubbish.

Serious question: Are you joking?

Now now, boys- you're both right.

–noun, plural -cies.
1.   the condition or quality of being true, correct, or exact; freedom from error or defect; precision or exactness; correctness.
2.   Chemistry, Physics. the extent to which a given measurement agrees with the standard value for that measurement. Compare precision (def. 6).
3.   Mathematics. the degree of correctness of a quantity, expression, etc. Compare precision (def. 5).

In the common English language, I think accuracy can refer to any of those definitions.

Fair enough, but we're talking about psychometrics, for which definition 3 is appropriate.

I think either definition would be appropriate, depending on how you're talking about it. You're both right. Neither of you is wrong. ...but if ya'll wanna whip it out right here, then I'm game too.
