For years, most people thought that video games were like candy: mostly bad, tempting to children, but okay in moderation. Now we understand that they can have more "nutritional" value than our parents ever imagined.
the positive effect of regularly eating breakfast, or getting a proper night's sleep, was three times stronger.
the effects were small, with the positive effects of exercise being more significant.
A broader look at evidence provided by some other high quality studies again suggests the story is not clear-cut.
Playing electronic games, however, was not seen as leading to a greater risk of hyperactivity, or friendship or emotional problems
So how much time should we, or our children, spend looking at screens? It is difficult to be precise as different people spend time online in such different ways.
Anxieties over technology's impact on society are as old as society itself; video games, television, radio, the telegraph, even the written word—they were all, at one time, scapegoats or harbingers of humanity's cognitive, creative, emotional, and cultural dissolution. But the apprehension over smartphones, apps, and seductive algorithms is different. So different, in fact, that our treatment of past technologies fails to be instructive
To combat addiction, you have to discard the addicting substance," Turkle wrote in her 2011 book Alone Together: Why We Expect More from Technology and Less from Each Other. "But we are not going to 'get rid' of the Internet. We will not go ‘cold turkey’ or forbid cell phones to our children. We are not going to stop the music or go back to the television as the family hearth.
it's really hard to do purely observational research into the effects of something like screen time, or social media use," says MIT social scientist Dean Eckles, who studies how interactive technologies impact society's thoughts and behaviors. You can't just divide participants into, say, those with phones and those without.
that 0.36 percent means that 99.64 percent of the group’s depressive symptoms had nothing to do with social media use.
In datasets as large as these, it's easy for weak correlational signals to emerge from the noise. And a correlation tells us nothing about whether new-media screen time actually causes sadness or depression
research on the link between technology and wellbeing, attention, and addiction finds itself in need of similar initiatives. They need randomized controlled trials, to establish stronger correlations between the architecture of our interfaces and their impacts; and funding for long-term, rigorously performed research
