here's a good thing to tell school-age children: the textbooks they use to learn are made by people, and those people might gloss over or omit parts of the whole truth, accidentally or intentionally

basically just teach kids to be critical of their sources of info and ask really good questions

@typhlosion when I was a kid, I was told basically "anything in a nonfiction book (assuming subset of 'acceptable books') you can take as a factual source." that was kinda painful to deprogram growing up. :|
@typhlosion I suspect a lot of people were taught that too. I have a theory about--how information is handed down, why we have this inherent bias--but it's less important than the hope that humanity is maybe finally getting away from that dangerous mindset. XD
