You probably over corrected. Anytime you change your behavior in an attempt to emulate something (being unbiased, in this case), you are going to render yourself susceptible to skewed actions/responses.
Edit: This is one big reason why many believe MBTI to be a poor system. The test tends to have very poor reliability (or so I hear) due to response bias that is difficult to avoid.
Edit 2: I, personally, do not believe MBTI to be a poor system. I do believe relying on the tests to type someone is problematic, but there are many other ways to type someone, anyway.
I used to "straddle" a few different types based on online tests. However, after reading some more opinions and thoughts, like the ones on the first page, and reading more about the cognitive functions, I think I am starting understand that MBTI types more (within the context of myself). Especially when considering what dreamoftheunkown said about how the tests "work."
I think that I used to come out as INTP sometimes, and INTJ other times because I learned to be slightly more orderly with respect to my thoughts and especially my work. As a result, I think when I answer some of the questions I have some "J" tendancies. But when reading about the introverted thinking, and the extroverted intuition, and stating to understand how an INTP has a tendancy to try to understand the world around them. As opposed to the INTJ who supposedly has the tendancy to try applying their ideas to the world and "change it." When considering this, I think that I am an INTP that has consciously developed some habits that on a test would make me look slightly "J."
Another recent anomaly I found is that I sometimes come up "ISTJ" on some tests. There are some aspects of the ISTJ profile I identify with: for example the loyalty and sense of duty. However, there are others that make me think "that's not me." I don't remember any examples. My interpretation of this is as follows: The difference between the "S" and the "N" has to do with the difference between the concrete/detailed and the abstract way of thinking. I know when I was in uni, I did not have much in terms of "detail" oriented thought processes. Even now, I deal a lot with the abstract. The abstraction and breaking down of ideas and concepts, is to me, something that would be "more" "N" than "S." (correct me if I am incorrect with this).
My personal explanation is that I "was" more INTP, but I have consciously (through my life experiences) developed an attention to detail in my observations. Sometimes, this attention to detail leads me to interpret questions in a way that makes the test result look like I think more in detail ("S") while also thinking in abstract ways "N."
The more I learn about the cognitive functions, the more I think I am indeed an INTP that has simply developed some other aspects of my personality. The tests can't pick up these nuances, and as a result I seem to straddle ISTJ/INTP/INTJ "spectrum". I also am starting to think that there is no such spectrum and that three MBTI types are indeed quite different.
Oh, another point for me personally has to do with F vs T. Sometimes I feel as though my emotions take over and I make decisions based on extreme emotions. Does this make me more "F" than "T"? I think it has more to do with how I interpret the questions on the test. In reality, I think I have a personal struggle with understanding emotions and knowing how to respond to them. I think I am extremely underdeveloped when it comes to the "F" which only makes me more Thinking and Feeling.
Mostly, I am simply trying to support the premise that the tests are merely a starting point. A slight slant in any way (intentional "unbias") actually skews the test results. I would also argue (based on my limited knowledge of MBTI) that the notion of "intentional unbias" is a strong INTP trait, more so than INTJ. A proper understanding of the cognitive functions and how the tests work would allow you to make the correct judgement on your personality.
Cheers.
