A long-term study by researchers from Georgetown University, the University of Southern California (USC), and the University of California, Berkeley (UC Berkeley) found that changes in how U.S. adults use social technologies do not strongly predict their life satisfaction. Published in Nature Human Behaviour, the research followed 1,966 adults over 12 months through five surveys. Participants were asked about their use of 10 social platforms, including Facebook, Instagram, TikTok, and YouTube, and their overall life satisfaction was measured using a simple three-question survey. The study aimed to answer two key questions: whether frequent use of specific social platforms is linked to higher or lower life satisfaction, and whether changes in how often someone uses a platform over time affect their happiness. Using a statistical method called Bayesian analysis, the researchers found no strong evidence that changes in social media use predicted life satisfaction three months later. These results were consistent across all platforms and demographic groups, including men and women, people of different ages and income levels. Kostadin Kushlev, one of the lead researchers, noted that while some platforms like TikTok and YouTube were associated with lower life satisfaction, this might be due to factors like age rather than the platforms themselves directly causing unhappiness. He stressed that the study only included adults and does not address the potential effects of social media on children or teenagers. The study also found that people with higher life satisfaction were more likely to use video calling services, but the researchers acknowledged that their data relied on self-reports, which may not fully capture how often people use these technologies. Kushlev emphasized the need for more objective measures, such as tracking phone usage directly, to better understand the relationship between social technology and well-being. Looking ahead, Kushlev and his team plan to use more precise methods to measure social media use and study younger populations, including teenagers. They are currently conducting a new study where adolescents receiving their first smartphones will be randomly assigned to groups with or without access to social media. The study will track phone usage using specialized software to explore how access to social media affects the well-being of young people.
