So what. This isn't a Facebook problem. It's an education and gullibility problem. There should be a class in the every high schools history department the explains propaganda and gossip.
It wouldn't help. Facebook and other social media outlets are geared to giving you more of what you click. Happen to click a few far Z-Wing posts? You'll get more. Once a pattern develops they feed you what you click most so that you'll stay engaged. No amount of high schooling will prepare people for that. The _only_ way to fight it is to actively disengage.
This is most certainly a problem Facebook created, however. Blaming the public for "not knowing how to use nukes better" while still building and cramming nukes in their inboxes is just ridiculous and it's time for this charade to end.
Also this doesn't help the majority of the population that is older than high school age.
Propaganda is done because it works.
Poor financial literacy = HS tax class
Misinformation on social media = HS propaganda class
Teens can't deal with their emotions = HS yoga class
Also we read Animal Farm and we talked about propaganda in history classes. Another class just for Facebook is not the solution.
