Over the last month or so I have undertaken some light research of "what is fact (trust), opinions, and folklore". The premise being that the information we encode in Verifiable Credentials should, to the extent possible, represent information that is 100% fact/trust and something else should be used encode options, and folklore (e.g. the DIDComm messages (with authenticated encryption) might be an answer for the latter [Daniel Hardman]).
Here's 2 blog posts I've created:
* Truth and Marketplace of Ideas (https://hyperonomy.com/2022/12/13/marketplace-of-ideas/)
* Facts, Opinions, and Folklore: A Preliminary Taxonomy (https://hyperonomy.com/2022/11/19/facts-opinions-and-folklore-a-preliminary-taxonomy/)
Be prepared for a sojourn into topics such as: what is evidence, US Constitution law (specifically the First Amendment), New Institutional Economics, Marketplace of Ideas, etc.
Best regards,
Michael
