Do Smart Phones Make You Smarter?
Is your smart phone making you smarter? Does your car direction finder make you eligible for NASA training school, and your camera phone enables you to be a Walter Cronkite reporter-wannabe so savvy you can skip four years of journalism classes? Modern techie devices can be helpful and make life easier, but there are serious drawbacks, says a Texas A&M University professor who studies technology.
Jonathan Coopersmith, professor of history at Texas A&M, says modern technological devices used to demand learning specific skills and acquiring the necessary resources to do them. For example, if you wanted to make a film, you got a movie camera and the supporting technologies (film, lights, editing equipment), and then learned how to use them and hire a crew to handle all of the equipment. Next, you would shoot the movie, then develop and edit the film, and the final step would be to make copies and distribute them.
"But many of those steps are eliminated today," Coopersmith says.
"Now all of those tasks are solved by technology. We need no longer learn the intricate details when the smartphone programmers do it for us. Technology has made us individually dumber and individually smarter. Technology has made us able to do more while understanding less about what we are doing, and has increased our dependence on others."
These are not recent trends, but rather part of the history of technology, Coopersmith says.
In recent decades, three major changes have accelerated the process: first, the increasing pace of humans specializing in particular skills: second, the outsourcing of more skills to technological tools, like a movie-making app on a smartphone, that relieve the challenge of learning large amounts of technical knowledge. And three, many more people have access to technology than in the past, allowing them to use these tools much more readily.
"Specialization enables us to become very good at some activities, but that investment in learning — for example, how to be an ER nurse or computer coder — comes at the expense of other skills like how to grow your own food or build your own shelter," Coopersmith says.
"As Adam Smith noted in his 1776 book Wealth of Nations, specialization enables people to become more efficient and productive at one set of tasks, but with a trade-off of increased dependence on others for additional needs. So in theory, everyone benefits.
"Specialization has moral and pragmatic consequences," Coopersmith says. "Skilled workers are more likely to be employed and earn more than their unskilled counterparts. One reason the U.S. won World War II was that draft boards kept some trained workers, engineers and scientists, working on the home front instead of sending them to fight. A skilled machine tool operator or oil-rig roustabout contributed more to winning the war by staying at home and sticking to a specialized role instead of heading to the front with a rifle. It also meant other men (and some women) donned uniforms and had a much greater chance of dying."
A major downside of increased dependence on technologies is what happens when they break or even disappear, Coopersmith says.
"Just one example of many is that the U.S. Naval Academy just resumed training officers to navigate at sea by sextants," he says. "Historically the only way to determine a ship's location at sea, this technique is being taught again both as a backup in case cyberattackers interfere with GPS signals and to give navigators a better feel of what their computers are doing."
How do people survive and prosper in this world of increasing dependence and change?
"It's impossible to be truly self-reliant, " Coopersmith says, "but it is possible to learn more about the technologies we use, to learn basic skills of repairing and fixing them (hint: always check the connections and read the manual) and to find people who know more about particular topics. Thinking about what happens if something goes wrong can be a useful exercise in planning or a descent into obsessive worrying.
"As a country, we also should be more proactive about encouraging more socially beneficial consequences," Coopersmith says. "What do we want new technologies to do? How can they be developed, diffused, and adapted to strengthen an inclusive democracy? As Mel Kranzberg, a founder of the history of technology, said, 'Technology is neither good nor bad. Nor is it neutral.'"
"Individually, we depend more on our technologies than ever before — but we can do more than ever before. Collectively, technology has made us smarter, more capable, and more productive. What technology has not done is make us wiser."
