Smart technology (probably) isn’t making you dumber

Technology usually has more pros than cons, but every benefit still carries some risk.

Smart technology (probably) isn’t making you dumber

  • A new paper in Nature Human Behaviour states that technology is not making us dumber.
  • The authors believe smart technology changes how we engage our biological cognitive abilities.
  • While fears are likely overblown, technology addiction and memory problems still need to be addressed.

    It seems that every major scientific or technological advancement is immediately labeled "dangerous" by critics. The printing press was going to destroy our memory. Pasteur's groundbreaking work was followed by an anti-vaccine movement. Radio was going to destroy society; then it was television; then, the internet. Pushback against progress appears inevitable.

    Of course, technology is usually morally indifferent. Smartphones can be used to video call your grandparents or order illegal drugs. How we use technology is what matters.

    Smart tech, dumb people

    The newest fear is that smart technology (smartphones, computers, tablets, the internet of things, etc.) is supposedly making us dumber. But a trio of authors, led by Lorenzo Cecutti, argue in a new paper that smart technology is not turning us into dummies.

    According to co-author Anthony Chemero, the idea that smartphones and digital technology damage our biological cognitive abilities is not backed up by science. Instead, he claims that we are developing different relationships to cognition due to smart devices. "What smartphones and digital technology seem to do instead is to change the ways in which we engage our biological cognitive abilities."

    The team cites research that found that using digital technology as an external memory system doesn't take into account the fact that short-term effects do not necessarily indicate long-term changes to cognitive functioning. They write, "Relying on external tools when they are available is not the same as losing the ability to engage internal processes when necessary."

    Other research disagrees with that conclusion. The famous London cab driver study showed that cabbies had larger hippocampi and better memory than non-drivers. Other research shows that GPS reduces spatial awareness and mental mapping. Studies such as these indicate that — as the cliché goes — if you don't use it, you lose it.

    More good than bad

    Still, the authors are correct that fear about the dangers of technology is overblown. Technology generally makes life better. In particular, the team considered five ways in which smart technologies are especially useful:

    • Complexity. Fields such as data visualization, financial accounting, and statistical analysis all benefited from the speed and accuracy of technology.
    • Reliance and skill. Advances in computational ability free up cognitive resources so that coders and data scientists can focus on understanding data and building better programs.
    • External access --> Freed capacity. The internet offers far greater access to information than any previous technology. Because we don't need to memorize, our mental resources are free to be used for creativity or learning other things.
    • Flexibility. People can freely choose what information to memorize and what to offload.
    • Self-insights and self-control. With so much information at our fingertips, we can choose what to focus our attention on. (However, this assumes that smart tech isn't addictive.)

    There's always some risk

    While the team ably counters the fear-mongering around the "dumbing down" of humanity through technology, they also seem a bit too enthusiastic about championing its advancements. Chemero concludes:

    "You put all this technology together with a naked human brain and you get something that's smarter...and the result is that we, supplemented by our technology, are actually capable of accomplishing much more complex tasks than we could with our un-supplemented biological abilities."

    That is certainly true, to a degree. But we should also be aware that every benefit comes with a cost.

    Here's another thing to consider: what happens if your smartphone or the internet stops working?

    Surprising Science
    • It appears that Earth has a geologic "pulse," with clusters of major events occurring every 27.5 million years.
    • Working with the most accurate dating methods available, the authors of the study constructed a new history of the last 260 million years.
    • Exactly why these cycles occur remains unknown, but there are some interesting theories.

    The first three minutes: going backward to the beginning of time with Steven Weinberg (Part 1)

    The great theoretical physicist Steven Weinberg passed away on July 23. This is our tribute.

    • The recent passing of the great theoretical physicist Steven Weinberg brought back memories of how his book got me into the study of cosmology.
    • Going back in time, toward the cosmic infancy, is a spectacular effort that combines experimental and theoretical ingenuity. Modern cosmology is an experimental science.
    • The cosmic story is, ultimately, our own. Our roots reach down to the earliest moments after creation.

    Ancient Greek military ship found in legendary, submerged Egyptian city

    Long before Alexandria became the center of Egyptian trade, there was Thônis-Heracleion. But then it sank.

    Surprising Science
  • Egypt's Thônis-Heracleion was the thriving center of Egyptian trade before Alexandria — and before earthquakes drove it under the sea.
  • A rich trade and religious center, the city was at its height from the six to the fourth century BCE.
  • As the city's giant temple collapsed into the Mediterranean, it pinned the newly discovered military vessel underwater.
