I'm on the line of integration/disintegration between a 9 and a 3. I picked 9 for the poll since 9 is the more likely Enneagram type for an INFP, and my stacking is sx/sp which, IIRC, usually brings out a more aggressive side in 9s. I relate equally to both the 3 and 9 profiles, though.
(Although I just took the test at Eclectic Energies and now it's saying I'm a 4. What? Oh, Enneagram, I give up on you ...)
