Watch what happens when you sit in any university library, the kind with long wooden tables, the soft hum of air conditioning, and a sign near the entrance telling students to turn off their phones. Nearly every table will have someone pick up their phone within ten minutes, unlock it, take a quick look, and then put it back down. Sometimes they don’t seem to read anything at all.
The gesture has become so reflexive that the person performing it frequently doesn’t seem to be aware of the decision they just made, which is part of what makes it intriguing. The conduct is so routine that it hardly registers anymore. Researchers at Budapest’s Semmelweis University have spent a lot of effort trying to figure out what’s going on in those moments, and their findings contradict the most popular hypothesis.
Many people believe that excessive smartphone use is a sign of a personality disorder. that those who are neurotic, worried, or inclined toward addictive behavior are just more susceptible—that addiction is like to a personality trait that manifests itself through a gadget. According to the Hungarian study, which included individuals between the ages of 18 and 35, this framing is either incorrect or overly simplistic. The decisive factor is not personality.
Self-control, specifically the ability to control one’s own impulses and emotional reactions in the moment, is significantly more important. Fear of Missing Out, which is a continual, low-grade fear that something is occurring elsewhere that you are not seeing and that picking up the phone can alleviate that feeling, at least momentarily, sits next to that and is nearly as significant. Seldom does it. Nevertheless, the cycle continues.
Based on how participants really use their gadgets, the researchers separated them into three groups, and the differences are more significant than the names would imply. The least likely to develop an addiction were social users, or those whose phone usage is mostly focused, active, and conversational. Consumers with moderate content were in the middle, balanced in their consumption without falling into passive absorption.
The most vulnerable category was the third, which consisted of heavy process-oriented users who spent four to five hours a day passively browsing. The nature of the content consumption itself—rapid, fragmented stimuli arriving in a stream that never demands sustained attention—seems to be what drives the risk in that category. The attention span adjusts to the task at hand, and passive scrolling requires it to perform minimal tasks for extended periods of time.
Although less shocking, the study’s physical effects are nonetheless worth mentioning. The forward head posture that results from staring down at a screen for extended periods of time, known as “text neck,” gradually deteriorates the health of the neck joints and can eventually lead to real balance issues.
The mental processing that late-night scrolling triggers keeps the brain in a state of low-level awareness that resists the transition into adequate rest, which is why sleep disturbance from midnight usage is now well-documented across dozens of research. Heavy users also exhibit memory impairment and shorter attention spans, which raises issues that the researchers are cautious not to answer with more certainty than the data supports: it’s still unknown how much of this is reversible and how quickly once usage patterns shift.
Budapest’s proposal is purposefully low-key. The researchers are not advocating for device-free zones, prohibitions, or the kind of drastic behavioral changes that usually fall apart in a week. What they’re recommending is more modest and, presumably, more credible: disable unnecessary notifications, establish a specific endpoint for evening scrolling, and move the phone before bed.
Concentrate on the issue of self-control instead of the phone. That framing, which is pragmatic, somewhat resigned to human nature, and concentrated on minor tweaks rather than large gestures, seems to capture the psychology of the situation as it truly is. The enemy is not the phone. It’s the impulse.
