Search engines are rerouting our memory. According to Science, we're not necessarily losing our ability to remember things. Rather, the internet is changing how we remember. Ars Technica sums up the results nicely, "People are recalling information less, and instead can remember where to find the information they have forgotten." This is pretty similar to a 2008 report in The New York Times on reading online versus reading in print. Guinevere F. Eden, director of the Center for the Study of Learning at Georgetown, told The Times, "The brain is malleable and adapts to its environment," she said. "Whatever the pressures are on us to succeed, our brain will try and deal with it. The question is, does it change your brain in some beneficial way?"

Certain types of memory are improving. When the brain reroutes how we recall information, it develops different types of memory capabilities. Science offers this example: If somebody asks you how many national flags have just one color, do you think first about the actual flags? Or does your brain jump right to how you would find it? If you're an active Google user, you probably already started thinking of keywords. And the more you do it, the better you get at it. "The brain is very specialized in its circuitry and if you repeat mental tasks over and over it will strengthen certain neural circuits and ignore others," says Gary Small, a neuroscience professor at UCLA.

Multitasking makes memory worse. This one seems obvious, but scientists are learning more about what exactly happens when you're flooded with the many distractions available online and try to engage. Comparing how well 60- to 80-year-olds could retain memories after a distraction versus 20- to 30-year-olds, a 2011 study linked attention and memory. Scientists found that our short-term memories while multitasking deteriorates over time. In other words, as we get older, we have a harder time with distractions. And the Internet will only make it worse. "This issue is growing in scope and societal relevance as multitasking is being fed by a dramatic increase in the accessibility and variety of electronic media," said Dr. Adam Gassaley, a neurologist at the University of California, San Francisco.

Not using Google makes you stupid, too. A 2008 study at UCLA's Memory and Aging Center looked at how Internet-usage affected not only memory but also cognition. Led by Dr. Small, the scientists split a group of subjects between 55 and 76 years of age into a group of experienced and inexperienced Internet users, then used MRI scans to see how their brains worked when reading books or searching the web. Experienced Internet users actually showed increased brain activity, with more advanced decision-making skills and complex reasoning. In simple terms, the inexperienced Internet users lagged behind. Check out the brain on the right (with Google practice) versus the one on the left (without Google practice):

In a way, this is an age-old argument. Hieronimo Squarciafico, a 15th-century Venetian editor and critic of the printing press, once said, "Abundance of books makes men less studious." That may be true, but that doesn't necessarily mean they make us dumber.
