I am on ministers' retreat. Listening to the speaker, I think all sort of 'meta' things. One takeaway for me is that we often feel pleased with ourselves that we have broken out of or avoided an echo chamber, just to find that we have put ourselves in another one.
Echo chambers - if we mean people that think like we do - have the advantage of rubbing the rough edges off our thinking, but the disadvantage of sometimes entrenching wrong thinking.
Academics avoid this by 'thinking against the grain' - but unfortunately (I think) this means that radical ideas may be revered even if they are not rational.
The universe seems to tend towards anti-intellectualism one way or another.
