Look at the bright side - you actually tested as one thing. I test as a 3456w9 (often tying with a minor 9). I've never come across this on any other test... and considering that enneagram uses +/- calcs... it's quite something.
Yes, some of these tests give results that are all over the place...These ones seem to be more conclusive if you haven't tried them already:
“There are two novels that can change a bookish fourteen-year old’s life: The Lord of the Rings and Atlas Shrugged. One is a childish fantasy that often engenders a lifelong obsession with its unbelievable heroes, leading to an emotionally stunted, socially crippled adulthood, unable to deal with the real world. The other, of course, involves orcs.” ~ John Rogers
The strong 5 score is definitely due to the NT temprament. Overall, my MBTI seems to explain me better though because the stereotypical type 8 is not seen as a "Rational" like the MBTI classifies the ENTJ type. Being an NT, I would consider myself a mental/intellectual person and I'm not a big hunk, physical type I'm of average complexion so the 8 stereotype of big muscles and physical conflict is far from who I am. For me, it's more to do with the energy, willpower, determination, assertiveness, desire to protect and of course of "doing my own thing".
No personality test is completely accurate. Although several measures were taken to make this test as accurate as possible, there's always a chance that you are not typed correctly by it. Therefore, when deciding which Enneagram type and wing you are, you might also want to consider the types with the highest test scores on the lists below.
