My God, it's like if Mark Rosewater was also a Nazi.
Cards on the table, I love M:tG as a game design nerd, and the color pie is a really well-done tool for keeping the game interesting and fun over it's very long history and even longer list of expansions and extensions. From a mechanical perspective, it strikes a beautiful balance between allowing the player to do exactly what they want and preventing the player from just doing everything. Without the color pie, it's easy to see deck building descend into an attempt to assemble the strongest individual cards. It's telling that basically every other CCG has some kind of mechanism to solve the same problem, but I don't think any of them have done it as cleanly or in a way that so smoothly enables players to combine mechanics and elements from different colors.
From a narrative perspective it's a great story engine that allows for all the disparate settings, characters, even genres that the game has explored over its life to still have a cohesive identity - to rhyme. I would argue that part of why the world's beyond sets have seemed wrong is because the settings weren't designed from the ground up to align with that narrative tool, and no matter how good the actual card designers at WotC are it just isn't going to rhyme properly, like trying to translate poetry to a different language family. But that's beside the point.
As a psychological model of the world? I mean I guess it's a tool for categorizing and narrowing down the ways that different people interact with each other or the world or whatever. But that's fundamentally not what it's for! Even as bad as the science behind the MBTI or whatever might be, at least they were designed from looking at actual people and intended to categorize them and understand them. This is the equivalent of trying to do therapy based on people's fucking Hogwarts house. Hell, even that was actually intended to fucking categorize people. Like, even without getting into all the ways that he's extending and distorting the actual color pie as used in Magic to match his own fixations, the whole project is so blindingly wrong-headed from the start that it ought to be an old BuzzFeed listicle and not something that people actually use in any clinical setting, even if it is just his wacko girlfriend.

Update!
The rich fuckers are apparently inclined to acknowledge this as ridiculous, at least in part. Here's hoping that this doesn't stall out and at least some Americans get to report at least one unambiguous public policy win in 2026
