Expert warns smartphone addiction is causing cognitive decline, recommends 'friction' strategies to regain control
A Guardian columnist argues that willpower is insufficient against the 'attention economy' and suggests practical interventions such as greyscale mode and time-out applications to help users reclaim cognitive capacity.
A mental health professional writing for The Guardian’s Modern Mind column has reported that clients are experiencing significant cognitive decline, including reduced memory, shortened attention spans, and difficulty concentrating, which they attribute to excessive smartphone use. The author, who observes these trends in clinical practice, notes that nearly all affected individuals trace their symptoms to the pervasive presence of mobile devices, which often remain within reach during meals, work, and rest.
The article highlights anecdotal evidence from a client, an academic in her early 40s, who described experiencing "brain lapse." She reported losing the thread of conversations and television dramas, noting that a single check of her phone could result in 40 minutes of unintended scrolling. Across the author’s practice, clients ranging from teenagers to those in their mid-50s have reported similar issues, with self-reported usage metrics indicating six to eight hours of daily screen time, and some individuals exceeding 10 hours.
The author argues that the "attention economy" operates as a business model rather than a metaphor, employing engineers and cognitive scientists to design features such as infinite scroll and variable rewards to capture user attention. Because these designs are engineered to exhaust willpower, the columnist contends that relying on personal discipline is insufficient. Instead, the recommended approach involves creating "friction"—deliberate obstacles that provide the rational brain with time to intervene before impulsive scrolling occurs.
Specific interventions suggested include switching phones to greyscale mode to remove dopamine-triggering colour cues, using time-out applications to lock out social media, and removing apps from the home screen to increase access difficulty. The author also advises keeping devices out of reach during meals and disabling non-essential notifications. The academic client, who has implemented these strategies, reported reading two books in three weeks and regaining the ability to follow complex narratives without distraction.
The column clarifies that the goal is not to eliminate technology but to restore the ability to use phones as tools rather than being used by them. The data presented is based on observations from private practice rather than broad scientific consensus, and the effectiveness of the proposed strategies is supported by anecdotal client outcomes rather than controlled trials.
