Mental Strength Training: Why Reading is the Antidote to the Smartphone
This year marks a special milestone for us as we celebrate ten years since Radnor first opened its doors. To mark our tenth anniversary, we are hosting a series of themed weeks, and I am delighted that this week is dedicated entirely to the power of reading. With a community challenge to read 10,000 pages in just seven days, we are making a bold statement about the value of the written word.
However, as we celebrate a decade of growth as a school, we find ourselves at a strange global crossroads. While our children have more information at their fingertips than any generation in history, the way they process that information is fundamentally changing. I often find myself looking around on the train and at a restaurant noticing how the rustle of pages has been replaced by the silent glow of a screen. It is not just a change in habit, it is a change in how our children’s brains are being wired.
The Rise and Stagnation of Human IQ
There is an increasing body of evidence suggesting that general intelligence may be in decline after rising steadily for much of the past century. For decades, we benefited from the Flynn Effect, a consistent rise in IQ scores of roughly three points per decade driven by better nutrition and expanded education. However, that upward trajectory began to plateau in the 1990s and has shifted into a steady decline over the past ten years.
We are seeing "red flags" on the global dashboard of teenage intelligence. Data from the Programme for International Student Assessment (PISA) shows an unprecedented drop in performance across mathematics and reading, with this accelerating in the past five years.
Why Reading is Our 'Mental Weightlifting'
At Radnor, we believe that reading is the ultimate form of "mental strength training" for the brain. It stimulates the regions responsible for building complex mental models and develops the cognitive empathy required to navigate perspectives beyond our own.
The challenge we face today is the "skimming" culture of the smartphone. Modern devices are architecturally addictive, designed by engineers to maximise engagement through short-form content. This systematically erodes a child’s ability to persevere with long-form, complex text, which is the very scaffolding the brain requires to form new neural connections. When we consider that Gen Z now averages six hours of smartphone usage daily, the implications for their cognitive future are profound.
Protecting the Radnor Spark
The decline in reading is a primary victim of this technological saturation, with reports showing literacy levels in many developed countries are in active retreat. We cannot simply wait for a societal shift. We must act as a community to protect our children's ability to think deeply.
As we celebrate our first ten years as a school, we are recommitting to this mission. We want our students to be more than just digitally literate. We want them to be cognitively resilient, capable of the deep focus that a screen-dominated world tries to take away.
The 10,000 Page Challenge
Our 10,000-page reading challenge this week is more than just a competition, it is a collective effort to reclaim our focus. We have invited all parents to support their children in hitting this ambitious target by recording their reading. Together, we can ensure that Radnor’s second decade isn't defined by a decline in focus, but by a resurgence of deep, independent thought.
