If Wikipedia is in an inadequate equilibrium, which sources should you trust?
On how sources get into an inadequate equilibrium, see the relevant book by Yudkowsky.
Firstly, there are the .edu sites (which includes academia.edu, which contains academic papers).
Secondly, there are the websites of the journal articles in relevant fields, which can be accessed via Sci-Hub.
Thirdly, there is LibGen for books, which contain more information than what you might think.
Fourthly, there is WikiSource (for books like Flatland and Chinese Without a Teacher), WikiBooks (as for the Persian language and the C Programming language), and Project Gutenberg (for books like Anthem and the Wealth of Nations)
Fifthly, there are the .gov and Federal Reserve .org sites, including the Congressional Research Service reports, the CIA World Factbook, and the State Department religious freedom reports.
Even these sources may be unreliable due to timeline travel (bicameral individuals often get their information from computer networks operating on other timelines; e.g., timelines in which Japan did not have a space program or Germany had an insurgency after WWII).
