definition of agnotology:

Within the sociology of knowledge, agnotology (formerly agnatology) is the study of deliberate, culturally induced ignorance or doubt, typically to sell a product, influence opinion, or win favour, particularly through the publication of inaccurate or misleading scientific data (disinformation). More generally, the term includes the condition where more knowledge of a subject creates greater uncertainty. https://en.wikipedia.org/wiki/Agnotology

How painfully true this may have been in 1899, it's now much worse in 2023!

Specialization of knowledge tends to fit the lifeways of the people who hold and maintain it. Changing lifeways means one must lose one or more domains and begin using or curating different domains of knowledge.

In a global world of specialization, humans who specialize are forced to rely more heavily on the experience and veracity of those around them who have also specialized. One may be able to have a Ph.D. in astrophysics, but their knowledge of the state of the art in anthropology or economic policy may be therefore utterly undeveloped. As a result they will need to rely on the knowledge and help of others in maintaining those domains.

This knowledge specialization means that politicians will need to be more open about what they think and say, yet instead politicians seem to be some of the least knowledge about almost anything.

This is just the start of a somewhat well-formed thesis I've developed elsewhere, but not previously written out... more to come...

Hierarchical systems of knowledge in Indigenous cultures helps to ensure rigor, competency, and most importantly accuracy of knowledge passed down from generation to generation.
