Concerns about “brain rot” from digital technology have surged, with claims that excessive screen time impairs cognitive function. However, experts argue that this moral panic lacks scientific backing.
Andrew Przybylski, a professor at Oxford University, studies technology’s impact on cognition. He dismisses alarmist headlines, pointing out that low-quality research often exaggerates negative correlations to attract attention and funding.
While online risks exist, he emphasizes the importance of learning to navigate them, just as we do with other everyday hazards.
Studies claiming technology alters brain structures fail to establish cause and effect, says Shane O’Mara, a professor at Trinity College Dublin. Brain structures change throughout life—for instance, during pregnancy—without necessarily indicating harm.
He also highlights historical parallels, noting that people have always sought distractions, whether through tabloids in the 1950s or social media today.
A 2023 study by Przybylski and colleagues analyzing data from 12,000 children found no evidence that screen time negatively affects brain connectivity or well-being. In contrast, access to technology correlates with increased happiness and social connection among youth.
Franck Ramus of the École Normale Supérieure refutes claims that digital media reduces IQ, stating that global IQ levels rose throughout the 20th century before plateauing—an expected limit of human cognition. The decline in some studies remains inconclusive.
Philosopher Tony Chemero argues that technology changes cognition without harming it. Humans have always adapted to new environments; outsourcing memory to devices, for instance, allows brains to focus on other tasks.
Similarly, psychiatrist Gary Small found no compelling evidence that digital technology causes permanent brain damage. Instead, he highlights potential benefits, such as cognitive stimulation, social connectivity, and mental health interventions.
Although excessive screen exposure can lead to temporary distractions, Small’s study demonstrated that taking breaks—like five days at a nature camp—can quickly restore social and emotional intelligence. He advises managing devices wisely rather than fearing them.
Experts suggest a balanced approach: avoid excessive multitasking, take breaks, and be intentional about media consumption. Przybylski, who does not restrict his children’s screen use, believes the real issue isn’t screens themselves but the displacement of other beneficial activities.
Ultimately, technology is a tool—how we use it determines its impact. As O’Mara suggests, simply stepping away, reading uninterrupted, or going for a walk can help maintain cognitive well-being without succumbing to unfounded fears of brain rot.
