>Is there any proof that the algorithmic echo chamber is a real thing? I don’t use any social media that has algorithmic curation, but I still get the strong feeling that I’m in a bubble whenever I encounter other internet bubbles. How much is just caused by me choosing to see things I already agree with instead of a computer choosing for me?

There are multiple other factors beyond algo or yourself. 1 study I saw proving echo chambers used reddit r/history where their moderators enforce an echo chamber on purpose. They go way beyond banning viewpoints like holocaust denial. Even basic misunderstandings of non-controversial history are banned. Thus resulting in a objective echo chamber.

That same study went to look at more controversial subs and places like r/canada where moderators ban people for viewpoints they too have an objective echo chamber.

From my point of view echo chambers have been objectively proven to exist. In some cases that's the intention but ultimately echo chambers certainly exist.
