How Much Screen Time Should Toddlers Have? None, Sweden Says.
Swedish public health authorities recommended this week that children under the age of 2 should not use any digital media, as parents, pediatricians and governments struggle to respond to the challenges of today’s tech-soaked world. ... “The most educational thing is another human being — who is not looking at a phone,” said Kathy Hirsh-Pasek, a senior fellow at the Brookings Institution and a professor of psychology at Temple University.

Do Phone Bans Help Students Perform Better in School?
Millions of children who head back to school this fall will find their phones are now gadgets non grata. Chancellor of New York City public schools David Banks has said that he is considering a ban on classroom phone access that would affect 1.1 million students, though the ban will not be in place at the start of the school year. ... Better academic performance is one factor supporting the bans. But another—mental health—has also captured the attention of policymakers and the public. Jonathan Haidt, a social psychologist at New York University’s Stern School of Business, has posited that social media (which young people primarily access on phones) is causing a teenage mental health crisis.

To Play or Not to Play with Your Kid?
It shouldn’t be this hard to decide. ... Yet some parents seem to be absorbing the message—especially from social media, the great flattener of nuanced communications—that in playing with their kids, they might be doing them a disservice, and that all children, regardless of age, temperament, or ability, should be capable of initiating and sustaining play for long periods. I asked Roberta Golinkoff, a developmental psychologist and the founder of the Child’s Play, Learning, and Development Lab at the University of Delaware, if she has come across any research supporting such interpretations. “I’ve been in this business a long time,” she said—50 years.

Your Cynicism Isn’t Helping Anybody
When I describe “cynics,” you might conjure up a certain type of person: the toxic, smirking misanthrope, oozing contempt. But they are not a fixed category, like New Zealanders or anesthesiologists. Cynicism is a spectrum. We all have cynical moments, or in my case, cynical years. Cynicism—the belief that all people are selfish, greedy, and dishonest—is a natural response to a world reeling from social division, rising sea levels, and countless other problems. But that doesn’t mean it helps us. Cynics suffer at basically every level scientists can measure.

Chatbots Are Primed to Warp Reality
More and more people are learning about the world through chatbots and the software’s kin, whether they mean to or not. ... Pataranutaporn and his fellow researchers recently sought to understand how chatbots could manipulate our understanding of the world by, in effect, implanting false memories. To do so, the researchers adapted methods used by the UC Irvine psychologist Elizabeth Loftus, who established decades ago that memory is manipulable. ... Loftus, who collaborated on the study, told me that one of the most powerful techniques for memory manipulation—whether by a human or by an AI—is to slip falsehoods into a seemingly unrelated question. ...
