I took the MBTI (at humanmetrics) maybe a year or two ago and was typed as an INFJ. After taking a pencil-and-paper version of the MBTI a few weeks ago with someone who is licensed to administer it, my type came out to an INFP, with my preference scores being I (19), N (35), F (0), and P (13). I took the test at humanmetrics again today to see what result I'd get, and I was again deemed an INFP, this time with a much stronger NF.
Anyway, is it really possible to go from a J to a P? Do you think it may have been a fluke the first time? Is it common to get a different result if you take the MBTI more than once?
