When I first became interested in the Enneagram, sometimes I would mistype as a 4. It was until later that I realized I shared the qualities of the 6 much more than the qualities of the 4. I have a friend who is (I think) a confirmed 4 and I see a lot of the same personality traits shared between us.
Have you ever mistyped as a 4? Do you think it is common for six to mistype as a 4? What personality traits do you think are similar/contrasting?
