Our own Morgan Meis in The Smart Set:
People find a great deal of satisfaction worrying about attention span, at least for a little while, and especially in the realm of popular culture. Twitter is the latest culprit. It's recent importance in organizing Iranian street protests notwithstanding, the 140 character posting limit on Twitter makes a certain kind of person nervous. Such persons (such as Baroness Susan Greenfield, a scientist at Oxford University) wonder whether tweeting and other such activities “encourage instant gratification and make young people more self-centered.” She goes on to say, “My fear is that these technologies are infantilizing the brain into the state of small children who are attracted by buzzing noises and bright lights, who have a small attention span and live for the moment.”
Unfair to the inherent joys of buzzing noises and bright lights, the statement is particularly galling to those of us who are rather fond of the moment, and living therein. One wonders during which time period the Baroness would prefer we live. I will leave wholly without comment the fact that Baroness Greenfield is also a Patron of Dignity in Dying.
