But that mechanism for belief transmission within EA, i.e. object-level persuasion, doesn’t run afoul of your concerns about echochamberism, I don’t think.
Getting too little exposure to opposing arguments is a problem. Most arguments are informal so not necessarily even valid, and even for the ones that are, we can still doubt their premises, because there may be other sets of premises that conflict with them but are at least as plausible. If you disproportionately hear arguments from a given community, you’re more likely than otherwise to be biased towards the views of that community.
Yeah I think the cost is mostly lack of exposure to the right ideas/having the affordance to think them through deeply, rather than because you’re presented with all the object-level arguments in a balanced manner and groupthink biases you to a specific view.
