One’s tone while reacting isn’t so relevant though.
Echo chambers are far simpler than that: It’s being surrounded by people who agree with you and you agree with them.
Example: 7 people clicked “Like” on this thread.
This is no firm metric but it’s a clue that there _might_ be an echo chamber of 9 here:
a) The author of the article (whose communication is one-way)
b) Yourself implicitly by posting it and also by agreeing to it
c) The 7 people who clicked “like”
This forms an echo chamber.
“Something should be done about this”
“Oh yes, definitely”
etc, bouncing around.
Many people believe they are of independent mind, unencumbered by things like echo chambers, because they’re able to point to someone *else’s* echo chamber, not recognizing their own.
Neither am I free of the dangers of echo chambers. But I *think* at least I can recognize when I’m in one that supports / amplifies. Do you know your own echo chambers?
