In my work there are 3 guys who use your typical doom-scrolling apps, and they are basically what their feed show them. One of them is a fan of X thing, and their feed is constantly showing them how good is X thing and how bad is Y and Z, the algorithm would NEVER show them the contrary because they'll stop using the app, so they keep being fed with the same thoughts although they might be wrong, they might know that they are wrong but there's enough "evidence" (an infinite amount of short videos telling them what they wanna hear), and is exactly the same with each one of them, The most curious thing is, although as human beings we have our own personality, each one of them tends to "adapt" their personality to mimic what the stereotypical Tiktok guy says.

In my country recently were the presidential elections, and I found it specially funny because people who never in their lives talk about politics, now wear a shirt of their favorite political party, but is specially funny when they can't argue for themselves why they choose to prefer that political party, instead they show you an image from Tiktok where say that X o Y political party is bad because of W or Z.

Edit: Just read rule 3 after posting (oof). I don't want to specifically talk about politics anyways, that were one example.
