Smartphones have by now been implicated in so many crummy outcomes—car fatalities, sleep disturbances, empathy loss, relationship problems, failure to notice a clown on a unicycle—that it almost seems easier to list the things they don’t mess up than the things they do. Our society may be reaching peak criticism of digital devices.

Even so, emerging research suggests that a key problem remains underappreciated. It involves kids’ development, but it’s probably not what you think. More than screen-obsessed young children, we should be concerned about tuned-out parents.

Yes, parents now have more face time with their children than did almost any parents in history. Despite a dramatic increase in the percentage of women in the workforce, mothers today astoundingly spend more time caring for their children than mothers did in the 1960s. But the engagement between parent and child is increasingly low-quality, even ersatz. Parents are constantly present in their children’s lives physically, but they are less emotionally attuned. To be clear, I’m not unsympathetic to parents in this predicament. My own adult children like to joke that they wouldn’t have survived infancy if I’d had a smartphone in my clutches 25 years ago.

When Alexei Navalny boarded a plane to Moscow on January 17, he turned his life into a metaphor. He knew it, his wife knew it, and everybody else on the plane knew it. So did the millions of people who had watched his documentary videos, who had seen the witty interviews he did on the plane, who have since joined demonstrations in his name. So did the leaders of Russia, including the country’s dictator and president, Vladimir Putin. This, Navalny was telling all of them, is what courage looks like.

Navalny is Russia’s most important opposition leader, and he was flying home from Berlin after spending many weeks in a hospital there, following the second or perhaps the third attempt on his life. He’d survived because a German NGO had sent a plane to Omsk to take him out of Russia, because the Novichok nerve agent used to poison him doesn’t always kill you right away, and because the Russian hospital had agreed to let him go, probably on the assumption that he would never return. (For the record: One of the doctors who treated him for poison has since died under odd circumstances, and a hospital official who refused to attribute Navalny’s illness to poison has been promoted to regional health minister.)

If you are on the proverbial market, as you rack up phone swipes, first dates, and—likely—new sexual partners, you might start to ask yourself, Is all this dating going to make me happier with whomever I end up with?

In other words, are you actually getting any closer to finding “the one”? Or are you simply stuck on a hedonic treadmill of potential lovers, doomed like some sort of sexual Sisyphus to be perpetually close to finding your soul mate, only to realize—far, far too late—that they are deal-breakingly disappointing?

Well, sociology has some unfortunate news!

Over at the Institute for Family Studies, Nicholas Wolfinger, a sociologist at the University of Utah, has found that Americans who have only ever slept with their spouses are most likely to report being in a “very happy” marriage. Meanwhile, the lowest odds of marital happiness—about 13 percentage points lower than the one-partner women—belong to women who have had six to 10 sexual partners in their lives. For men, there’s still a dip in marital satisfaction after one partner, but it’s never as low as it gets for women, as Wolfinger’s graph shows:

If the immune system ran its own version of The Bachelor, antibodies would, hands down, get this season’s final rose.

These Y-shaped molecules have acquired some star-caliber celebrity in the past year, due in no small part to COVID-19. For months, their potentially protective powers have made headlines around the globe; we test for them with abandon, and anxiously await the results. Many people have come to equate antibodies, perhaps not entirely accurately, with near imperviousness to the coronavirus and its effects. Antibodies are, in many ways, the heartthrobs of the immune system—and some 15 months deep into immunological infatuation, the world is still swooning hard.

Frankly, it’s all getting to be a little too much.

The last election’s most unexpected twist is framing one of the most urgent questions confronting both parties today: What explains Donald Trump’s improved performance among Latino voters?

The president who began his first national campaign by calling Mexicans “rapists,” drug smugglers, and criminals; who labored to build a wall across the U.S.-Mexico border; who separated undocumented children from their parents; who sought in court to end the “Dreamers” program; who maneuvered to reduce virtually every form of legal immigration; and who told Democratic women of color in the House of Representatives to “go back” to where they came from—that president won a higher share of Latino voters in 2020 than he did four years earlier, according to every major exit poll and precinct-level analysis of last year’s results.

It started, as so many of life’s journeys do, at IKEA. We went one day a few years ago to get bookshelves. We left with some Hemnes and a leafy impulse buy: a giant Dracaena fragrans. A couple of months later, delighted that we had managed to keep it alive, we brought in a spritely little ponytail palm. And then an ivy. A visiting friend brought us a gorgeous snake plant. I bought a Monstera online because it was cheap and I was curious. It arrived in perfect condition, in a big box with several warning labels: perishable: live plants.

Where is the line between “Oh, they have some plants” and “Whoa, they are plant people”? I’m not quite sure, but I am sure that we long ago crossed it. I would read the periodic news articles about Millennials and their houseplants and feel the soft shame of being seen. But I cherished our little garden. Potted plants have a quiet poetry to them, a whirl of wildness and constraint; they make the planet personal. I loved caring for ours. I loved noticing, over time, the way they stretched and flattened and curled and changed. I still do.

“How to Build a Life” is a weekly column by Arthur Brooks, tackling questions of meaning and happiness.

Arthur C. Brooks will discuss the science of happiness live at 11 a.m. ET on May 20. Register for In Pursuit of Happiness here.

In his 1851 work American Notebooks, Nathaniel Hawthorne wrote, “Happiness in this world, when it comes, comes incidentally. Make it the object of pursuit, and it leads us a wild-goose chase, and is never attained.” This is basically a restatement of the Stoic philosophers’ “paradox of happiness”: To attain happiness, we must not try to attain it.

A number of scholars have set out to test this claim. For example, researchers writing in the journal Emotion in 2011 found that valuing happiness was associated with lower moods, less well-being, and more depressive symptoms under conditions of low life stress. At first, this would seem to support the happiness paradox—that thinking about it makes it harder to get. But there are alternative explanations. For example, unhappy people might say they “value happiness” more than those who already possess it, just as hungry people value food more than those who are full.

An image of George Floyd and his daughter Gianna has been circulating around social media since yesterday. George is sitting in the driver’s seat of a car, wearing a black T-shirt and black baseball cap with the word Houston emblazoned in cursive letters above the brim.

In the passenger seat is Gianna, who is now 7 years old, but in the photo—taken a few years ago—looks as if she isn’t more than 3 or 4. She is wearing a purple-and-pink shirt and matching pants and a small plastic bracelet on her right wrist, and has several silver and pink bobbles tied into her hair. Her right hand is holding a pair of plastic blue-and-black sunglasses—the sort made for children with the expectation that they will not last very long—and she looks as if she has pulled the large glasses down from her face and to her chin specifically for the picture.

If you’re like most Americans, there’s a good chance you’re going to wear a cloth mask today. Doing so makes sense. It remains the official recommendation in the United States, and it is something we’ve both advocated since the beginning of the pandemic. Both of us wrote articles as far back as March urging people to wear homemade cloth masks. We’re also the authors (along with 17 other experts) of a paper titled “An Evidence Review of Face Masks Against COVID,” which was just published in peer-reviewed form in the Proceedings of the National Academy of Sciences. But it’s past time for better solutions to be available to the public.

We first released the paper as a preprint back in April, and it took nine months to go through peer review. We’re happy that it’s published but, to be honest, we’re also deeply disappointed that it’s still relevant. We’d hoped that by 2021 supply chains would have ramped up enough to ensure that everyone had better masks. Cloth masks, especially homemade ones, were supposed to be a stopgap measure. Why are so many of us still wearing them?

Like many parents, Jason Newland, a pediatrician at Washington University in St. Louis and a dad to three teens ages 19, 17, and 15, now lives in a mixed-vaccination household. His 19-year-old got vaccinated with Johnson & Johnson’s shot two weeks ago and the 17-year-old with Pfizer’s, which is available to teens as young as 16.

The 15-year-old is still waiting for her shot, though—a bit impatiently now. “She’s like, ‘Dude, look at me here,’” Newland told me. “‘Why don’t you just tell them I’m 16?’” But because certain pharmaceutical companies set certain age cutoffs for their clinical trial, she alone in her family can’t get a COVID-19 shot. She’s the only one who remains vulnerable. She’s the only one who has to quarantine from all her friends if she gets exposed.
