White Diamond MBTI Personality Type
Personality
What personality type is White Diamond? White Diamond is an ISTJ personality type in MBTI, 1w2 - so/sx - 135 in Enneagram, RCOEN in Big 5, LSE in Socionics.
Stays in her "head" ship 24/7 and sends a mind-controlled Pink Pearl to do her bidding. No, White Diamond is an introvert. The hierarchy of gem society is indicative of TeFi and not FeTi as the Diamonds are COMPLETELY out of tune with the feelings of their subjects as per PoLR Fe in White and Demon Fe in Yellow. Look at how all the gems meshed together like gears during the Homeworld Ball and tell me that isn't a product of Te. That leaves NiSe vs. NeSi, and I don't see any Ni in White, or any of the diamonds. Homeworld adhered to a very strict status quo indicative of SiTe before Steven came along. You may argue that the GDA's conquest of the universe and mass genocides is a product of a consequentalist Ni vision but when you get down to it, its just a routine for them, no different than us getting up in the morning and taking a shower; a product of Si. Besides, White's breakdown quote "But I'm not supposed to be like this. I'm supposed to know better. I'm supposed to BE better. I'm supposed to make EVERYTHING better." is what SiFi beliefs look like when they break down. She does not take action towards some grand vision, but because she was made for a purpose and is adhering to it (Unhealthy Si-dom). She thought Pink Diamond would reform from Steven's gemstone when she removed it but when that didn't happen and when Steven and Pink Steven fused again her Teritary Fi beliefs were "shattered" to make a pun.
