Longtime ago, I made a small installation [1] at an HCI conf about the same larger issue. Increasing Search Engines seem to train people by judging their inherent confirmation bias. I think many recommendation engines also try to do the same to a lower extend by keep the 'subject' happy. It was interesting to see how designers from leading companies present never thought their work actually makes people live in bubbles and they always think it was 'UX friendly'.
