I've been obsessing a bit about personality types (a longtime favorite obsession, actually) since picking up an old issue of Utne Reader the other day. I looked up the Myers-Briggs test this morning (although I've taken it a million times), and found myself cracking up...
"A major concern for INTPs is the haunting sense of impending failure. They spend considerable time second-guessing themselves. The open-endedness (from Perceiving) conjoined with the need for competence (NT) is expressed in a sense that one's conclusion may well be met by an equally plausible alternative solution, and that, after all, one may very well have overlooked some critical bit of data. An INTP arguing a point may very well be trying to convince himself as much as his opposition."
I test on the borderline between T/F and J/P, which is why I've taken it so many times. But if that isn't me, I don't know what is.
More: "The internalizing nature of the INTP's Sensing function leaves a relative absence of environmental awareness (i.e., Extraverted Sensing), except when the environment is the current focus. Consciousness of such conditions is at best a sometime thing."
That explains my schizophrenic housekeeping.
