The Elephant Rider model (or whatever similar childrens model of the mind so far developed - Plato's Chariot, Kahnemans System 1/System 2, Freuds id/ego/super ego, Hobbes Passions+ Reason, Hegels Master-Slave, Cherokee 2 wolves etc etc) is the 3 inch chimp brains attempt at recognizing it is not a single unitary system, but multiple layers. Those layers, and there are many more that what anyone is taught, are a requirement for the system to make predictions over different time horizons. Contradictions between those predictions requires stories for the system to stay coherent. Personality traits are one such story.

Interesting article, but MBTI is not just contested, the concensus since the 90s is that MBTI is pseudoscience [1][2][3][4][5], so it's nearly 40 years.

Would have been interesting to test against the Big five instead !

Is that because they're trained on the navel gazing posts of reddit nerds?

Have you tried Big 5 too?

I’d guess that is what you get for training them on source code.

Also the I vs E axis feels meaningless in this case.
