So after Careful analysis, I have determined that the only types needed for a functioning society
Are INTJ's, ISTJ's, ENTJ's and ESTJs
The rest of you and by you I mean us are unnecessary.
I would say they need to exist in certain ratios.
ISTJ and INTJ should outnumber ENTJ and ESTJ 100:1
*By careful analysis I mean it popped into my head and I immediately types it up.
