In Praise of Shortened Attention Spans

Popular wisdom holds that American attention spans have diminished over the past few decades. But cultural critic Terry Teachout thinks that's just fine:

The latest alleged trend to set the world in a tizzy is the Crisis of Shorter Attention Spans, a dire development that has been brought about by the rise of the Internet. Or texting. Or iTunes. Or Twitter. Or whatever. I find it hard to get upset about this existential threat to Western civilization, though, perhaps because I'm part of the problem. My attention span is much shorter now than it was a decade ago—and that's just fine with me.
Part of the "problem," after all, turns out to be that Americans have gotten smarter, or at least quicker on the uptake. Take a look at any TV sitcom of the 1950s and '60s and compare it to modern-day televised fare. It's startling to see how slow-moving those old shows were. The same thing is true of live theater. The leisurely expositions of yesteryear, it turns out, aren't necessary: You can count on contemporary audiences to get the point and see where you're headed, and they don't want to wait around for you to catch up with them.
Does this mean that the discursive masterworks of the past are no longer accessible? Yes and no. A great work of art that is organically long, like "The Marriage of Figaro" or "Remembrance of Things Past," will never lack for audiences. But just as most of Shakespeare's plays can and should be cut in performance, so should today's artists always keep in mind that most of us are too busy to watch as they circle the airport, looking for a place to land.

What is the benefit of a shortened attention span? It encourages people to (as I find myself often asking in business meetings) get to the point, please:

Anyone who doubts the virtues of brevity should take a look at Oxford University Press's "Very Short Introduction" series, in which celebrated experts write with extreme concision about their areas of expertise. Each volume in the series is about 140 pages long and runs to roughly 35,000 words of text. (Most serious biographies, by contrast, run to between 150,000 and 200,000 words.)
How much can you say about a big subject in 35,000 words? Plenty, if you're Harvey C. Mansfield writing about Alexis de Tocqueville or Kenneth Minogue writing about politics. These "Very Short Introductions" are models of their kind—crisp, clear and animated by a strong point of view.

Teachout goes on at length about the series. But, honestly, I didn't read the whole article.
