The Shallows by Nicholas Carr was recommended in a meeting I was in. I'm glad I took the advice and got it. In the book, Carr examines the ways in which the Internet, for better or for worse, is impacting human evolution. His basic thesis is that the Internet is a tool that is fundamentally reshaping human reality and our brains in the process. This is not the first time a tool has done this. The clock and the map are two tools that situated human beings within time and space in a revolutionary manner. Our brain chemistry has adapted to the omnipresence of clocks and maps to such a degree that we cannot even imagine how humans existed without them. Many of us, in a similar manner, cannot remember life before the web.
Studies are beginning to show that multimedia educational experiences actually decrease learning opportunities because more of our brains are devoted to decision-making functions rather than absorbing and appropriating information. When my brain has to make myriad subconscious decisions about whether or not I am going to click on an embedded hyperlink or watch a video, it does not have full resources to grasp what I am actually reading.
Further, we read differently when we read online than when we read a hard copy book. Online reading is scattered and distracted, much like we read magazines or newspapers ... glancing and scanning headlines. Books are obviously different, expecting us to read in a linear fashion. When I read on a screen my brain is not used to following a linear path, making reading much more difficult. The counterintuitive truth is that electronic formats for learning in reality decrease recall and comprehension.
Other interesting observations in The Shallows include:
The expectation that we can outsource our memory to the cloud may actually reduce brain capacity rather than increase it.
A mere hour-long walk in nature before a test dramatically increases memory and recall.
For as long as they have existed, human beings tend to become one with the tools they use. This is true of a guitar, a hammer, and the Internet.
Google is both freaking amazing and freaking scary.
I come away from Carr's book with a few new commitments:
I have got to find more and better ways to unplug. I am way too addicted to all things digital and need to sabbath from them.
I am going to change the way I blog. Rather than embedding hyperlinks in text, I am going to list them at the end of a blog post. This way, my readers' brains can focus on what they are reading and making decisions about following links at the end.
I have serious doubts about the effect of the movement of our educational system toward e-content. I think this is something we are going to live to regret (think: Idiocracy).
The irony that I read this book on my iPad is not lost on me.
