Effects of restricting social media usage

Abstract

Recent research has shown that social media services create large consumer surplus. Despite their positive impact on economic welfare, concerns are raised about the negative association between social media usage and performance or well-being. However, causal empirical evidence is still scarce. To address this research gap, we conduct a randomized controlled trial among students in which we track participants’ digital activities over the course of three quarters of an academic year. In the experiment, we randomly allocate half of the sample to a treatment condition in which social media usage is restricted to a maximum of 10 minutes per day. We find that participants in the treatment group substitute social media for instant messaging and do not decrease their total time spent on digital devices. Contrary to findings from previous correlational studies, we do not find any impact of social media usage on well-being and academic success. Our results also suggest that antitrust authorities should consider instant messaging and social media services as direct competitors before approving acquisitions.

What Works to Improve Wellbeing? A Rapid Systematic Review of 223 Interventions Evaluated with the Warwick-Edinburgh Mental Well-Being Scales

“…Just one intervention, a 2-day course teaching health practitioners how to help patients with mental health or learning difficulties develop social networks, had a positive impact on wellbeing [ 218 ]. Other interventions that did not fit into previous themes included: couples massage classes (positive) [ 225 ], sleep education programme for parents (positive) [ 226 ], co-design of workplace solutions (positive) [ 227 ], social media restriction for university students (null) [ 228 ] and small-scale aids/home adaptations for dementia patients (null) [ 229 ].…”

Achieving social influence across gender and time: Are dominance and prestige equally viable for men and women?

“…These online social networks have become a ubiquitous and important part of modern life. Across age groups, genders, and cultures, people are spending an increasing amount of time on social networking websites, virtually interacting with others and sharing their thoughts, pictures, and life events (Williamson, 2020). As a result, online users' sense of self-worth, well-being, and social capital is derived from their connections and centrality in these online communities (Ellison et al, 2007;Steinfield et al, 2008;Wilcox & Stephen, 2013).…”
