The term echo chamber is assigned to groups that become sealed off from the world.
The truth is, we actually need echo chamber like groups. We need to know that we are not crazy. We need to find ourselves among people that share and mirror our beliefs.
The dangers of an echo chamber is that you stay in them and never test your beliefs against the real world.
Very well said!
That's right. There is value in testing your ideas in both environments (and the spectrums between). Thanks for reading and commenting!
