This is a growing problem because it's real and modern understanding is backwards.
I am curious as to what purpose you went to your uni library for. Medical research? Curiosity? What writings did you find? Why is it a problem that people use schizophrenia in conversation and writing? Not all discussion is medical research, and is certainly not held to those standards.
The commenter below, mentioning “truth-seeking” would need to define what they mean by truth. Is this capital T truth that applies to everyone or lowercase truth that applies to the specific and differing lenses we use?
Think kahnemans system 1/system 2 or the difference in reaction time of the (electrical)nervous system and the (chemical)endocrine system.
Culture generation happens along both time frames.
Engament metric driven social media and news media are all system 1. Reaction times ate fast. There is no system 2. It's still evolving.
So current Culture generation doesn't exhibit system 2 fall back when required.
Reforming the whole media system to not incentivise engagement. Let Facebook become a place where one shares family pictures with close relatives. Reward the YouTuber who produces infrequent 2-hour long videos that talk about philosophical ideas.
YouTube Longs.
I don't see how stories sharing some common structure (what does that even mean? rise-and-fall combinations?) makes it impossible to become overloaded by them.
I do agree with your second point though, especially when this is proven by the prevalence of the holy "algorithm".
I’d also reject the idea that the proliferation of stories really overloads people because stories follow their own physics (that I’d quarter-jokingly call pataphysics) and so constrained they recycle a limited repertoire of patterns. principles and archetypes and even if the details of the stories become a blur, one internalizes the structure.
