Check out this fascinating TED talk by Eli Pariser that I discovered last evening through my friend and wise colleague Heather Braum.  Here’s the abstract of this nine minute talk:

As web companies strive to tailor their services (including news and search results) to our personal tastes, there’s a dangerous unintended consequence: We get trapped in a “filter bubble” and don’t get exposed to information that could challenge or broaden our worldview. Eli Pariser argues powerfully that this will ultimately prove to be bad for us and bad for democracy.

These hidden “filters” of information are exactly why people of all ages need to understand how different search algorithms work in different information environments. This TED talk exemplifies why merely providing students access to the Internet is not enough and why information literacy skills matter more than ever in today’s world. When librarians embed themselves in learning spaces to facilitate authentic information seeking tasks in real-world, real problem-solving contexts,we can help people learn how to discover and thoughtfully evaluate a diverse range of information sources.
