Johnson highlights the ways in which some pop-culture is in fact more intellectually demanding than that of the past. He points to TV programs such as Hill Street Blues, The Sopranos, Seinfeld, and The Simpsons, with their continuous stories, multiple plot threads, and their references to other pop-culture. He also wrote a great deal highlighting the depth and intricacy of many computer games.
I could quibble on a few points. I think he gives cinema a little too much credit, basing his argument there primarily on a few intelligent films whose box office success ranged from weak to moderate. Strangely absent from Johnson's discussion is popular music, with no disclaimer nor any word of explanation for this. Since music is obviously a vast part of the pop culture landscape, its exclusion scores as a major omission.
But these caveats aside, I found that on the whole Johnson presented a very convincing case that a significant part of pop culture is in fact getting smarter. But regarding his premise that people are getting smarter as a result, that's where he got it very wrong.
For direct corroboration, the only hard statistic Johnson cites is the fact that IQ scores have been rising about 3 points per decade. By his own admission, they have been rising steadily at that rate for the last 70 years or so. Yet he perceives the smartening of pop culture as having started in 1981 (with the premiere of Hill Street Blues). So it seems a bit tenuous to claim the two phenomena are related.
Furthermore, IQ scores only measure a narrow range of intellectual abilities. What they measure is a rather mechanical, almost mathematical, sort of logical ability. They say very little about the more grey and nonlinear intelligence needed to comprehend, for example, literature or political science or comparative religion.
Aside from IQ score data, Johnson builds his case on anecdotal evidence, which in my view is easily refutable by other anecdotal evidence. Johnson presumes that since young people are the ones who soak up the most current pop culture, much can be gleaned from observing them.
That's a sensible rationale, so let's use it. Go into a fast food restaurant where young people work. See how many of them can make the correct change when the computerized cash register fails to work. Count how many teens you can find that can explain anything at length without stammering and peppering their sentences with like's and you-know's. And how long can a typical teen even watch TV without channel surfing?
Johnson acknowledges the studies that expose how embarrassingly little knowledge American students have of, for example, historical literacy. He claims that content is only secondarily important, that young people's skill at video games, computers, and general multi-tasking are skills that easily transfer to other sorts of tasks.
To some extent I would agree. But when significant percentages of young people can't even place the Civil War in the correct century, nor can they give a general description of what the Bill of Rights says, something fundamental and deep is lost. It's a bit simplistic to think that computer game agility is a skill that easily "transfers over" into a grasp of the subtleties of the philosophy of government. There are some intellectual capacities that can only be gained by studying certain things.
He also ignores the fact that these American young people seem to exhibit these skills primarily when something is lighting up, moving, and making noises. What about being able to study and learn when you don't know that there will be a definite reward, as there always is with a computer game? It's quite telling how rarely young people are willing to sit for an extended period of time in a quiet room with only paper and books and no electronic media.
The fact is, students in Russia and some European countries have consistently outscored US students on all sorts of scholastic tests. And they watch TV and play computer games less in those countries.
Johnson mentioned how every household today has a running joke about how the 9-year-old is the only one in the family who can set the VCR clock or figure out how to work the remote. True enough. But that could be for the same reason that any adult found it easier to learn music or a foreign language when they were children. That was always been true long before there was an electronic pop culture. Some skills by their nature are simply easier to learn the younger you start.
Though Johnson misses the point much of the time, I give him credit for attempting to answer a number of devil's advocate counter-arguments. He also writes in a plainspoken and engrossing style. Along the way in making his case, he gives some very readable exposition about other factual matters, such as IQ scores and the Flynn effect. However much or however little you'll agree with him, it's a captivating and enjoyable read.
