I don't know if you're trolling or not, but I will assume you are not.
The reason why I know Peterson came up with 0 things is that I have read him, and I have read the authors he has read, and realized he only took their theories and rewrote them with his own style.
Taking myself as an example, I came up with the term "progradiction" and its corollary, the progradict. I also came up with the Layer Theory, and more recently, the realization that we got self-development completely wrong (check out my Twitter account, or my upcoming article about Greek mythology).
That is, I move the conversation forward.
Did Peterson move the conversation forward? No, he didn't. What he's discussing now was already discussed by Augustine and Ambrose in the 4th century...
None of this is new, but since people don't read, they don't know.
I have written another article about this called "Joseph Campbell Is Like Jordan Peterson But Much Better".
