Researchers at the University of Milano-Bicocca have identified a link between early social media adoption and academic delays. By tracking over 5,000 Italian students, the study found that those starting at age 11 may fall six months behind in specific subjects by their mid-teens.
The six-month deficit in Italian and mathematics
The University of Milano-Bicocca study, which analyzed data from 5,227 Italian students, highlights a stark academic divide based on when children first access platforms like TikTok or Instagram. According to the report, students who opened accounts at age 11 or 12 scored significantly lower in mathematics and Italian by the time they reached ages 15 and 16 compared to those who waited until 14 or 15. This performance gap is estimated to be the equivvalent of half a year of lost schooling.
The researchers suggest that frequent phone checking and a lack of parental supervision may disrupt the concentration required for these core subjects. The study specifically noted that the negative impact was most pronounced in the lower-secondary school years, suggesting that the timing of first contact with these apps is a critical developmental window . While the study notes that intensive social media use is often linked to poor sleep and reduced face-to-face interaction, it did not find a direct connection to overall student wellbeing.
Why English scores remained unaffected by early app use
Interestingly, the research found no significant impact on English language test scores, even among the earliest social media users. The University of Milano-Bicocca team proposed that the sheer volume of English-language content available on global platforms might serve as a form of informal learning. This suggests that while digital distractions may hinder structured learning in math, the immersive nature of English-centric media might provide a different kind of cognitive exposure. This anomaly provides a unique perspective on how different types of digital content can influence specific academic disciplines differently.
From the UK's spring ban to Australia's nationwide restrictions
These findings arrive as governments worldwide move to restrict digital access for minors. The UK government has announced plans to ban social media for children under 16 starting next spring, targeting apps such as Snapchat, TikTok, and Facebook.. This move aligns with a growing global trend of legislative intervention, including Australia's nationwide under-16 ban and Brazil's requirement for legal guardian links.
Other nations are also pursuing similar age-based restrictions to protect younger users. France is moving toward a ban for those under 15, while Austria has announced plans to prohibit social media use for children under 14. In Indonesia, similar bans for under-16s have already been implemented, showcasing a diverse range of global approaches to the same digital challenge.
Correlation versus causation in the Milano-Bicocca findings
Despite the compelling data, some experts warn that the study's observational nature means it cannot definitively prove that social media causes academic decline. As the report notes, there could be other underlying factors that explain why students who use social media earlier also struggle more in school. one major open question remains: is the academic lag a direct result of digital distraction, or are students with different learning patterns simply more likely to seek out social media earlier? Additionally, it remains unverified whether parental supervision levels act as a mediator or if the age of cognitive maturity is the primary factor in these outcomes.
