I remember when I learnt about socionics/after mbti. I’d always been a little bit jealous/surprised that IEI didn’t have ni, in mbti, and then when they did in socionics, I was like ha! Yes. (But sometimes I think I want to go back to mbti so that will be interesting lol). Also, just to add, when I realised EIE was the more ‘creative’ one in socionics, over IEI..that was also an eye-opener. Though not that surprising lol
