You Tube's algorithm is not scarily good, it's scarily bad. It 100% over indexes on something that you watch and will then continuously send out tons of videos almost exactly like that. No discovery, no exploration - it simply sees something and then swarms you with it. The exact reason you need incognito mode to hide from it. The other thing it does, is continuously offer people extreme content of whatever genre because it thinks it can get high engagement. Whether it's UFOs, alt-right radicalizaion, or conspiracy theory of the day it constantly serves up content from the extremes of society because the people that do watch it typically become obsessive. The behavior of the people most susecptible to the fringes, because they watch so much youtube has enormous impact on what the majority of us see. YTs algorithm is absolute trash. There is a bunch of amazing content on Youtube, but I never find it due to recommendations. Only due to external pages that link to it which then show links to other related items. YT native recommendation is terrible. Watch a video and get recommendations for 30 other videos posted by that person, and 15 other videos on almost the exact same topic covering what you just saw. And then mixed in a few "Top 40" style videos from the genere you're in. Ie something barely unrelated, but is obviously popular. Absolute trash.
