I feel like a hypocrite writing about this on a blog, but I need to get the word out. In The Shallows, author Nicholas Carr brings together the history of technology and neurology to explore how the World Wide Web is changing the way we read and write—and think. What he finds is not pretty.

Actually, it's more than not pretty. It's downright disturbing. If you're reading this blog, you're probably a frequent user of the Internet, so let me ask you: When you are reading a book, do you often get distracted and want to do something else after only two pages? Heck, do you even read books anymore? Do you find it difficult to go walking for any substantial length of time without pulling out your phone, even if nobody is calling or texting you? Your Internet use may be to blame. And it probably is.

You see, the Internet is changing the way our brains work. A few decades ago scientists began discovering that the human brain, even in adults, can be "rewired" to accommodate changing behaviors, both physical and mental. Basically, the brain gets better and faster at what it does the most. And since it's more than likely that most of us are using the Internet with increasing frequency, our brains are adjusting themselves to a style of thinking better suited to the Internet.

What style is that? It's fast. It's superficial. It's distracted. If you haven't noticed, Web pages are designed to distract you. They're full of snippets of information here, a navigation bar there, pictures and a video you can play over there. Not to mention your browser's multiple tabs and all the alerts it's set to give you for e-mails, blog posts, or Twitter updates. I'm not accusing Web designers of sinister motives, but the plain fact is that the Web is made for giving you an onslaught of information all at once.

And our brains are burdened with processing all that information. With every link we come across, our brains have to decide whether to follow it. We have to skim pages to get the information we need fast. (My guess is this blog post already looks too long for frequent blog readers.) And since our brains are "plastic," or adaptable, they rewire themselves to be more efficient at this kind of thinking.

What gets sacrificed as a result is our ability to think deeply and creatively. Yes, maybe our brains are faster at processing a lot of information fast, but only at a superficial level. By frequently taking advantage of what the Web has to offer, we are denying ourselves the ability to synthesize the information we receive and produce original thought. Doesn't that sound scary to you? I guess it all depends on what's important to you, but I certainly place a high value on deep and creative thinking.

Everybody please, please read this book. I hate to be an alarmist, but I feel this is very important. Carr does an excellent job describing relevant research and presenting a coherent argument, much better than I've done here. Plus, by reading a book like this, you're doing a brain a favor. Because the good news is that since our brains can adjust to more frequent Internet use, they can also be trained back. With a lot of discipline, we can become free thinkers again.
