In the Everything Enneagram Book, the instructions for the test advise that you answer the questions as you would when you were twenty (if you're older, of course). For some goof ball reason, I didn't do that when I took it the first time- something to do with my never liking to follow directions, I suppose...
So, anyhoo, yesterday I did. It made everything crystal clear. For one, I tested 100% a type 4 (as in my answer to every single one of the type four questions was 'often'). What it came down to-
Me at 20: 4 7 183 65 2 9
Me now (36): 97 4/25 6/8/1 3
(the slashes mean ties; spaces signify how close they were in the results)
It's pretty insane to me that 9 comes out on top now (albeit barely) when before it would have been at the absolute bottom. Likewise, look at how much three has descended, while two and five have also worked their way up. I attribute some of this to being a stay-at-home mom, some to a bipolar episode which occurred a few years back and the lingering depression. (which up to taking this test I didn't really think existed. I 'feel' fine, but I'm also hiding and playing it safe so as to not rock the boat, so to speak.
Also, something I noticed was that when I tested at twenty, there was an absolute confidence to my answers. Now, there's a sort of hesitant ambiguity.
I did the same with the MBTI test in Lenore Thomson's Personality Types. Now, I come out as an extreme introvert ISFP. Testing at twenty, it's an almost ambivert INFP. (I 'officially' took the MBTI in high school and came out as an INFP, so there's further confirmation.)
Anyway, my point is that if you are older, taking the test as you would when you were twenty or so might really clear things up. I know it did for me.
