For a strange few decades that may just be starting to end, if you went to art school you'd be ostracised by your teachers for trying to draw good representational art. "Representational art" means pictures that look like real things. Art school actively discouraged students from getting better at drawing.
"Getting better at drawing" is off-topic at my weekly local drawing club too. I've literally never heard it discussed.
This taboo extends far beyond art. My nearest gym forbids weightlifters from using electronic systems to log their progress. I'm friends with programmers who can't touch type. None of them use Vim macros.
"I have sometimes suspected that the quickest way to get worried looks from many modern Western meditation teachers is to talk about practice in a way that implies the attempt to actually master anything." — Daniel M. Ingram
In the part of the United States where I live, the subject of skill is often taboo. Not just relative differences in skill level between specific present individuals (which would make sense). The implicit acknowledgement of skill as a trainable attribute is taboo.
Not all professions have this issue. Math is still math. Biology is still biology. One can politely discuss a cook's cooking. Magicians respect coin manipulation like it's 1904.
But when traditional colleges supply the labor force for a professional trade outside of academia, that's when discussion of skill (especially rote learning) becomes taboo[1]. College students learn everything about their trade except how to do it. Then we maintain a collective silence concerning technique.
- A Chinese major teaches you how to talk about Chinese, not how to read it.
- An English major teaches you how to talk about novels, not how to write one.
- An art major teaches you how to talk about masterpieces, not how to create one.
- A Computer Science Engineering major…well, you get the idea.
That's a partial explanation, but it doesn't explain why skill differences in weightlifting and meditation are also taboo.
Societies make taboo exactly those topics whose mere discussion threatens the precarious dominance of those at the top of the social order by drawing attention to the system's internal contradictions.
I think my society is hiding something from itself.
Medical school is an exception to this pattern. This may be because medical school considers itself a form of technical training, to be undergone after acquiring a liberal undergraduate education. ↩︎
Most of the the examples you have listed are observations made by you and your conclusions are too far reaching, in my opinion. There are many reasons for an art group to decide improving general skills is off topic. Do art schools actively discourage skill improvement? What is discouraging exactly? What defines a skill and getting 'better ' in terms of art? What I think you have observed is a small human behaviour which results in a group wide phenomenon. An emergent behaviour from fundamental systems within the human mind.
The science behind the topic is limited, most of what we can do is observation and speculation. I think the best approach is identifying key behaviours through reduction. One key behaviour I observe is how we learn, it is our greatest strength, it is the ability to learn complex topics and actions. The majority of times we learn a new process and its intricate steps, we continue to reproduce those steps exactly without question. Example:

The video above demonstrates, regardless of the reason, that we usually copy almost every action when learning from others. For most steps within a majority of our processes we do them without question. Another great example of something we learn but don't often question is the SIN and COS functions within math. This can connect to what you observed, a teacher learned art a specific way and continues to propagate it that way. You come along and question it, but it is already the norm, you are met with resistance. This is the culture of a topic.
I believe that these problems will always exist as they are based on the nature of how are brains function. A solution would be to teach self awareness on this problem so individuals can catch it. I first thought of suggesting, that we should just teach openness to foreign ideas but that can lead to the same problem, where change and openness are an obsession that we don't question or oppose questioning.
Humans like patterns and sticking to them. We like consistency and predictability.
