“How do you not know about {x}? It’s all over my apps!”
“Nobody can be ignorant of {x}. They must be lying if they say that they don’t know, it’s everywhere.”
“Literally everybody can see {x} is real/fake. They kept saying it.”
“Are you not seeing {x} suffer?”
“Are you not seeing {x} succeed?”
“Why are you so accepting of {x}? Don’t you see all the wrong they do?”
“Why are you so critical of {x}? Don’t you see all the good they do?”
So on and so forth. Many become misguided as their interaction with and knowledge of the broader world is more and more limited to what’s shown to them through feeds. More harmful is the assumption that everyone sees the same feed, or almost the same feed, with only tiny variations accounting for interests and hobbies. This is of course untrue. You can be completely removed from an entire facet of events depending on what the algorithm chooses to show you. The algorithm can also show you the same event through a comedically different lens by choosing a different narrator, and it’ll generally pick the one that aligns best with your views, because if it chooses otherwise, you’ll be less engaged.
A pretty good example is the Myanmar civil war. It is one of the most active civil wars, and it has never reached my feed other than that one clip of the girl dancing in front of an army motorcade rolling in. I’m sure that for some it is common to see posts about it, but for me it barely registers, and I had forgotten about it entirely until I recently looked up the ongoing civil wars. You will never have “the full picture”, because algorithms are not tuned to show you the full picture, and you cannot cognitively grasp the full picture anyway, only what you find interesting.
In time, the tendencies in your feed will surface as what you perceive to be truth. You won’t be able to fight it unless you are already skeptical of everything that you read online. You may believe yourself to be skeptical, but trust me, you’re not. You will read things that register in your mind as truth even if you’re not processing them intensely at the time, and you’ll eventually cite them later and forget where they came from. I thought I was one of those critical-thinking skeptics, but I found myself repeating crap I’d read online verbatim and sending it to others uncritically. Fighting against it requires an active cognitive effort and ultimately “moderation” when it comes to reading stuff of timelines and feeds.
