1 - I'm not going to YouTube shorts to be educated, but if Hank Green shows up and drops a fact on me that'll entertain me for 30 seconds, I'm good. It's not doomscrooling which was your original point.
2 - Well yeah that's a bad idea on most content websites, just because the lowest common denominator content is bad doesn't mean it's bad once you curate what you want to watch.
If you know that hurricanes come from warm waters and climate change has been making the water warmer, it makes sense why we've had back to back dangerous hurricanes. Climate change is completely false in MAGA world, but the amount and intensity of hurricanes has been increasing. So in MAGA world they need to answer why and they need to fill the climate change void. Since they are hitting red states in an election year, must be the Democrats controlling them.
I watch YouTube shorts sometimes, the algorithm gives me mostly comedy, usually some type of shketch where one person plays all the characters. I've also seen quick tip or educational videos, outdoor clips. None of what I engage with is doomscroling.
