So it's true, the web does make us dumber. Sort of.

What it's about:
The article makes a very important point - web usage rewires our brains to think in a certain not-entirely-great-for-mankind way and we carry that way of thinking into things we do. The web distracts us and interferes with our concentration.

Author Nicholas Carr: The Web Shatters Focus, Rewires Brains

During the winter of 2007, a UCLA professor of psychiatry named Gary Small recruited six volunteers—three experienced Web surfers and three novices—for a study on brain activity. He gave each a pair of goggles onto which Web pages could be projected. Then he slid his subjects, one by one, into the cylinder of a whole-brain magnetic resonance imager and told them to start searching the Internet. As they used a handheld keypad to Google various preselected topics—the nutritional benefits of chocolate, vacationing in the Galapagos Islands, buying a new car—the MRI scanned their brains for areas of high activation, indicated by increases in blood flow.

The two groups showed marked differences. Brain activity of the experienced surfers was far more extensive than that of the newbies, particularly in areas of the prefrontal cortex associated with problem-solving and decisionmaking. Small then had his subjects read normal blocks of text projected onto their goggles; in this case, scans revealed no significant difference in areas of brain activation between the two groups. The evidence suggested, then, that the distinctive neural pathways of experienced Web users had developed because of their Internet use.

I was thinking the same thing just two days ago, whether the web makes us dumber, especially after I read that Obama opined that it did.
