Someone in the replies brings this up, that trauma could be the result of learning something correct. Yud's brilliant response is that this makes no sense to describe this as trauma, because you don't get traumatized by physics class, right?

I feel like this is where first-principles rationalism + his intelligence god complex really shines through. He thought he had figured out the root cause of trauma, was told that this wasn't the case, then tries to redefine trauma itself instead of admitting that his (extremely simple, by the way) idea was wrong. I mean look at the way he starts his response:
Why then describe it as trauma ... ?
Because it's traumatic, that's why. No further explanation required.
AHAHHAAHAHAH
