Some years ago at another forum someone linked us to the Keirsey Character Sorter and a whole bunch of us took it. I scored INFP at the time.

According to the Wikipedia article, the Keirsey uses the same coding as the Myers-Briggs -- E or I, S or N, T or F, J or P -- but they're not otherwise the same.

Looks like perpetuallysad is talking about the Keirsey, too.

(Trying & Caring, I'm guessing that your score was "strange" mostly because it suggested that you weren't cut out to be a rogue pdoc! )
