Wiping your Watch History should fix it.

I always remove objectionable videos I accidentally watch from my Watch History to prevent the algorithm from using it a basis for recommending me stuff.

Hearing stories about YouTube recommending conspiracy videos always fascinates me because my own recommendations rarely veer in that direction, if ever. But I keep to a pretty strict diet of gaming/speedrun videos and bass (guitar, not fish) content, so what I see on my homepage almost entirely adheres to that.

But then I watch one innocuous video outside of my core interests—say, washing machine repair how-to, or a clip of an old sitcom, and then my feed gets infected with Jordan Peterson or other weird shit and I'm like ah, this is what everyone's talking about! And I have to go prune my watch history until they vanish. It's bizarre.

It's because Tim Dillon's audience tend to be low-info, populist-adjacent, Roganite potheads from Austin, TX.

I'm only somewhat familiar with Tim Dillon, and I agree with most of your statement, but why Austin, TX?
