This article makes far reaching societal claims with essentially no evidence. The evidence presented is in the form of "feelings" of various writers concerned of their own decline in literaryfocus. An unvoiced assumption that people were historically more literate pervades the entire article. As a former lit. major I used to buy into this kind of thing. But I now think this belief is the product of profound selection…
I don't know about you, but when I look at the popular media and at political leaders, they seem highly illiterate compared to those from just a century ago. Even the "literate elite" media, e.g. The New Yorker, has dropped in quality from a few decades ago. Just read some old issues to see what I mean.
Regardless, this article is hardly the first or only study of this problem. Allan Bloom wrote The Closing of the American Mind in 1987. Harold Bloom and John Simon wrote a few books on the topic.
