well, they are not common (enfp 1s), about 5% maybe, that is 1 in 20 (and there were 2 on typoc), as for 2s, i still dont know any 2s .... i wish i do, because i feel like that personality type is a myth
can you describe me how does 2 look like in RL... not by the book... why do you think enfj is 2, and not 3 for example.. because Fe is 2-ish, so... what else ?
i had a friend that is ESFJ i think and she acts like 2 but i am still not convinced, she could be 4 with occassional 2 tendencies, or a 3+Fe.
i have an XNFP friend (i mentioned him to you on wall) and he tested as 2 on the enneagram but i am preeeetty convinced he is a 4 that occassionally slides to 2.
