Anxiety about the effects of social media on young people has risen to such an extreme that giving children smartphones is sometimes equated to handing them a gram of cocaine. The reality is much less alarming. A close look at social media use shows that most young texters and Instagrammers are fine. Heavy use can lead to problems, but many early studies and news headlines have overstated dangers and omitted context. Researchers are now examining these diverging viewpoints, looking for nuance and developing better methods for measuring whether social media and related technologies have any meaningful impact on mental health.
