It's not as much as five going seven, it's five exhibiting five behaviour on five based principles that just seem like typical seven traits.
For example, "They constantly seek new and exciting experiences, but can become distracted and exhausted by staying on the go." is typically seven. But a five can also crave new and exciting experiences and become distracted/exhausted on the go, although fives would do this for the sake of data input instead of an innate compelling emotional desire that should be present in a seven. I'm a five that is a information junkie. I have always felt very related to many of the good traits of a seven, I read them and I'm like, hey, this all fits, so when I was new to typology, I thought I was a 7! But on closer inspection, the reasons why a seven shows seven traits are not the same reasons I show those traits, and looking at a seven's unhealthy levels, I don't relate to any of the bad. And although I rarily have bad moments in like the last 6 years now. Before that I have had very stressful times in which I couldn't quite deal with things the way I should have, and even then, it wasn't the seven bad traits I showed, but rather the five unhealthy levels.
So I came to the conclusion that my enneagram type must be five. Because all round that one seems to fit the bill. And all the seven traits I exhibit, are really just a means for me to indulge my five. And has nothing to do with actually being a seven at all. I'm all five, 100%! :>
Anyway, enough about me, this thread is about you!
And anyways enneagram typing seems to be quite a bit flawed, or rather, the tone in which the types are described is too strong. The way enneagram types present the various types, don't stroke well with me. It seems too black and white to be practical.
MBTI typing allows for more diversity within the types and also has a much more effecient and reliable means of testing. Seriously, most enneagram tests I took, they're so shaky!
