The ideas you suggest are interesting, I am very open to them, but just not sure how they would work in terms of practical applications. Thinking about creativity in terms of process rather than end products sounds good but how would it be measured? In education, measurements are made as grades, and I see it as unfortunately this results in declarations under strict divisions between pass, or fail. Even when processes are measured it is often by looking at work which is viewed and assessed, so in some ways it is about looking at certain evidence only.
The distinctions you make about dividing our creative resources across industries sounds interesting, but I am not sure what it would entail exactly. If you mean thinking about classifying them in terms of creativity I would certainly say that the many industries involve creativity, and this is not exclusive to the arts. This thread has not considered this comparatison between art and other disciplines at all, so it is good that you raise it, and I would be interested to know whether those who argue that the arts lack creativity would extend this to other areas, including the sciences or engineering.
However, if by your idea of extending our creativity across these realms you mean that each person needs to be enabled to pursue the various branches, I think that it would depend on abilities. Some people are all rounders and some are not. Personally, I find that I perform badly if I am expected to be good at all things equally. When I was expected to study for about 11 subjects at school I found it overwhelming and did less well than when I was able to specialise later. I have found that we are being meant to be able to do more and more in work situations.
In particular, when looking for work, I have found that job descriptions (in nursing) are pages long, with duties ranging from the technical to domestic. I have looked at such job descriptions and thought how could any one person be expected to do all these things? Actually, it seems that one is expected to be highly proficient at all tasks , and the only thing which is not expected is being able to do art.
Going back to the divisions you make about popularity, originality, reliability,and accuracy, I think that they are useful for thinking about ideas but I do not know how they would be used for forming actual structures. This is because they are not static. Of all them, popularity is the most changeable. If one was seeking that in a pursuit and fashions changed would they swing completely in another direction according to fit the new popular?I would say that your categories are a useful guideline for thinking about how we think about our own work in any field, but that it would be less helpful if the categories are seen too concretely.
