Your review of Eli Pariser’s The Filter Bubble: What the Internet is Hiding from You? (London: Penguin, 2011) goes along with much of what he has to offer concerning the dangers of the World Wide Web (”Invisible Sieve,” July 2, 2011). Two people querying Google for the same thing will come up with different results, for the browser takes each person’s search history into account. Facebook will be biased toward those friends you connect with more often. And Amazon will recommend new books or movies in accordance with each person’s past preferences. The “filter bubble” offers a unique universe of information. The author thus worries that “we are getting a lot of bonding but very little bridging.” Also, he worries about the “invisible autopropaganda, indoctrinating us with our own ideas.” He is right, of course, but not about the Internet. That is a human propensity that is only accentuated by the new technology. It is the task of each and every one of us to aspire to both bonding and bridging. The World Wide Web will follow us at a clip.
