Think about it. The more you learned about your brain the more complex it would become. Also I’m not sure we have enough capacity to reflect on ourselves by processing everything. Think about the massive complexity of every connection. Could someone actually process that or are we limited by ourselves?
I think the logic here is supposed to be something like:
more knowledge = more complex brain
as you need to “store” the knowledge somewhere.
I don’t say thats how it works but i can somehow see where OP is coming from.
