What type of person are you? (GA over)

Again, from the Contact page:

I got a different result when I took the personality test again after a while. Why?

We are continuously refining the test questions, trying to make our algorithm more accurate and reliable – consequently, you may be assigned a slightly different personality type if your original scores were very low (<10%). If you are unsure which personality type is truly yours, please see our main theoretical article. Additionally, don’t underestimate the power of your mood. Taking the test when you are well-rested, feeling good, and full of energy can cause you to answer questions with more “positive” responses than if you’re totally exhausted at the end of a long week. Rather than thinking of the best of times or the worst of times, or just how you’ve behaved this past month, or how you used to behave when you were younger, (or how you would like to behave...) answer the questions considering how you’ve actually responded to situations most often, during the course of your lifetime.

I assume the same applies to the other tests. These personality tests basically define your personality along a number of dimensions or metrics which gauge where you fall on a spectrum between two extremes. Your placement on these spectra indicates your dominant personality type, the "default" core personality to which you automatically switch. Your personality can change based on the environment or context, especially if you're at work (where one typically has a "work personality").

Keep in mind that providing a neutral answer typically disqualifies the question from use. Since a neutral answer does not provide any meaningful information, it is excluded. Thus, neutral answers are typically discouraged since they render less accurate results. This is why many political compass or spectrum tests do not allow neutral answers, since a neutral answer doesn't move one's position on the plane. Over time, one tends to interpret a statement or question differently as one's experiences grow, environment changes, and mood differs. As a result, one may be receiving a different result because one is interpreting the content of the test differently. This is why most professional personality tests are given in conjunction with behavioral analysis and interpreted by the professional: it minimizes the chances that the results will be inaccurate because the results will be provided by another person, not just an automated system.

(An anecdote: I have taken these tests multiple times and found that over time, I interpreted the questions differently and answered differently as a result. In doing so, my percentiles increased, which may indicate higher confidence in my result.)

As with all tests, even those founded in scientific research and developed by professionals, it is restrained by the limitations of the test. This is why many tests recommend one does not "overthink" the content of the test, since scrutinizing the language of each sentence or question can mislead one into answering in a way the test did not intend. When it comes to personality tests in particular, the test can only provide an approximation of one's personality. Accurately assessing one's personality requires a professional, not just some automated system. Even then, it's not an exact science due to the fledgling status of personality typology in psychology.

When interpreting the results of a personality test, keep in mind that low percentages can indicate either low confidence or mild disposition. The setting or mood in which you take the test also affects the scores, as can one's interpretation of the test's content (as noted above). Combine these three factors and it can lead to individuals receiving differing results. These different results can either indicate that you are a borderline case, your personality is not clearly defined, you are not attuned to your own personality (which can occur, especially among those with personality disorders), or the test is unable to accurately determine your personality. It could be any of the aforementioned.

Apologies for the lengthy reply. Just some input that may help you better understand why your results seem to differ.

Yes.

No! Potato arent cool! D: THEY ARE AWESOME!!!11!!!! D:

And whitelisted for being a comrade in potato love D:

That's unlikely, unless you were, say, 1% introverted. There's another test online that gives you a percentage for each individual cognitive function: http://www.keys2cognition.com/explore.htm
