Summary

A study of smartphone use shows that consumers’ excessive use of smartphones and social media may result from digital addiction. Self-control tools reduce usage and improve well-being.

Policy Relevance

Users, parents, and policymakers should support digital self-control tools.

Main Points

  • Many people spend considerable time every day on social media, and may check their smartphones 50 to 80 times each day.
     
    • One hypothesis is that digital technologies provide substantial consumer benefits.
       
    • Another is that digital addiction plays a role in digital technology consumption.
       
  • Key questions linked to the issue of digital addiction include:
     
    • Should parents limit children’s smartphone and social media time?
       
    • How can game companies, social media platforms, and smartphone developers contribute to consumer welfare?
       
    • What self-control tools should be available?
       
    • Would regulations such as the proposed Social Media Addiction Reduction Technology Act (SMART) be beneficial?
       
  • Self-control problems are said to occur when consumers use more of a product or service today than they would have chosen for themselves in advance.
     
    • The study considered 2000 American adults with Android smartphones.
       
    • Some were paid to reduce smartphone use, the "bonus treatment."
       
    • Others could limit their next day's smartphone use using a feature that could not easily be overridden, the "limit treatment."
       
  • The study found clear evidence of digital addiction.
     
    • Bonus treatment participants reduced use by 39 percent, and continued to use 19 percent less screen time after the treatment ended.
       
    • Limit treatment participants reduced use by 17 percent, with 89 percent of participants setting binding limits.
       
    • All underestimated their self-control problems and their own smartphone usage.
       
  • Both the bonus and limit treatments reduced behaviors typical of smartphone addiction, such as the use of a smartphone to fall asleep, using phones mindlessly, or using phones to procrastinate.
     
  • The bonus treatment group enjoyed improved well-being, including the ability to avoid distraction, and reduced anxiety and depression.
     
  • About one third of social media and smartphone use arises from self-control problems; there is unmet demand for effective digital self-control tools.
