This thread has gone awry.
I have scored 4 different results over the past 2 years, using various testing instruments, including Keirsey's PUMII. I initially scored INFP on a free online test (humanmetrics.com). Since then, I have scored INTP, ENFP, and INFJ. Every test is easily contaminated once you understand the dichotomies and the questions. However, once I purge the relationships from my mind, I'm still left thinking about the context of each question, and I become indecisive. One might say that being indecisive is a 'P' trait, but it may also be a 'T' trait in the search from a concise truth. Since I could probably find any typological reason for a single behavior, and characterize any person as any type for any reason, I have decided that various behaviors cannot be typologically assessed with any certainty. For instance, if a person were to be indecisive, I would not jump to the conclusion that they were a perceiving type. I would rather say that they are thinking about the options with scrutiny. If I see that this is habitual for them, then I might characterize them as a fairly indecisive person, not a 'P'. Being a 'P', or any other digit within the MBTI code, elucidates psychological preferences, not behaviors. The dichotomies are false anyway.
I think that, on a superficial level, the INFP profiles that I have seen describe me with the most accuracy, followed by INTP and ENFP. However, these descriptions are often superfluous and vague. They are hardly ever even remotely clinical.
I think the INTP archetype described my penchant for understanding systems and how I like to change them. However, a person of any type can grasp a system and synthesize it. I am more inclined to believe that my view of systems is largely a Te orientation because it requires external input, however, Ti oriented people need external input as well. So this is inconclusive.
The ENFP archetype represents a more inflated version of myself that requires more energy to uphold.
