Do you live in an echo chamber?
It's easy to. And it only seems to get easier.
Before we go on, you might like to read this article at The Atlantic which covers a large, recent echo chamber.
In case you don't read it, I'll summarise: Those on the further reaches on the political right in America are shocked that Barack Obama won a second term - because the right wing media they watch spent six months before the election saying that Obama would lose. It was regarded as disloyal, unpalatable and (at an editorial level) unprofitable to say anything else.
That's an Echo Chamber.
I don't follow much national or international news these days, but when I do I use three websites - The Independent, The Telegraph and BBC News. That covers most sensible biases.
