@thecanine@twtxt.net Yeah. I find that definition too broad and ambiguous (Is it only the same opinions? There are no opposing views, at all?). And I think that leaving a subjective metric, on when it is and is not, won’t help.
How about?
An echo chamber refers to situations in which beliefs are amplified or reinforced by communication and repetition inside a closed system and insulated from rebuttal. By participating in an echo chamber, people are able to seek out information that supports their existing views diminishing opposing views, potentially resulting in an unintended exercise of confirmation bias.
An echo chamber is an epistemic construct in which voices are actively excluded and discredited. It does not suffer from a lack of connectivity; rather it depends on the manipulation of trust by methodically denying all outside sources.
And we would need to go deeper on understanding what an epistemic construct is, but I think that’s too long for a twt.
