Many of the tales of controversy to emerge from the Trump administration have been abstract, or complicated, or murky. Whenever anyone warns about destruction of “norms,” the conversation quickly becomes speculative—the harms are theoretical, vague, and in the future.

This makes new Washington Post reporting about President Donald Trump’s border wall especially valuable. The Post writes about how Trump has repeatedly pressured the Army Corps of Engineers and the Department of Homeland Security to award a contract for building a wall at the southern U.S. border to a North Dakota company headed by a leading Republican donor.

The story demonstrates the shortcomings of Trump’s attempt to bring private-sector techniques into government. It shows his tendency toward cronyism, his failures as a negotiator, and the ease with which a fairly primitive attention campaign can sway him. At heart, though, what it really exemplifies is Trump’s insistence on placing performative gestures over actual efficacy. And it is a concrete example—almost literally—of how the president’s violations of norms weaken the country and waste taxpayer money.

In theory, Amazon is a site meant to serve the needs of humans. The mega-retailer’s boundless inventory gives people easy access to household supplies and other everyday products that are rarely fun to shop for. Most people probably aren’t eager to buy clothes hangers, for instance. They just want to have hangers when they need them.

But when you type hangers into Amazon’s search box, the mega-retailer delivers “over 200,000” options. On the first page of results, half are nearly identical velvet hangers, and most of the rest are nearly identical plastic. They don’t vary much by price, and almost all of the listings in the first few pages of results have hundreds or thousands of reviews that average out to ratings between four and five stars. Even if you have very specific hanger needs and preferences, there’s no obvious choice. There are just choices.

British Prime Minister Theresa May announced Friday that she “will shortly leave the job that has been the honor of my life to hold.”

The long-anticipated address, outside Downing Street, confirms that May will step down as the leader of the Conservative Party on June 7. She will remain prime minister until the party chooses a new leader, a process that will take approximately six weeks.

In many ways, May’s announcement marks a solemn end to a profoundly weak yet surprisingly stable premiership. But if the past three turbulent years of parliamentary deadlock, infighting, and division have demonstrated anything, it’s that May’s leadership ended a long time ago.

Her premiership didn’t begin that way. When May succeeded David Cameron as prime minister in July 2016, she inherited a parliamentary majority and a 20-point lead in the polls over the opposition Labour Party. She was dubbed the “New Iron Lady,” in a favorable nod to the country’s only other female prime minister, Margaret Thatcher. But she also inherited a policy challenge of historic proportions: to deliver on a referendum result she didn’t support, and take Britain out of the European Union.

In 1957, a beach ball–shaped satellite hurtled into the sky and pierced the invisible line between Earth and space. As it rounded the planet, Sputnik drew an unseen line of its own, splitting history into distinct parts—before humankind became a spacefaring species, and after. “Listen now for the sound that will forever more separate the old from the new,” one NBC broadcaster said, in awe and insistent that others join him. He played the staccato call from the satellite, a gentle beep beep beep.

Decades later, we are not as impressed with satellites. There have been thousands of other Sputniks. Instead of earning front-page stories, satellites stitch together the hidden linings of our daily lives, providing and powering too many basic functions to list. They form a kind of exoskeleton around Earth, growing thicker every year with each new launch.

I’m an economist. I love data and evidence. I love them so much that I write books about data-based parenting. When questions arise about how to support parents at work (for example, from Alexandria Ocasio-Cortez on Twitter), my first impulse is to endorse paid parental leave. Mountains of data and evidence show that paid leave is good for children’s health, and for mothers in particular. I am more than comfortable making a data-based case for this policy.

But experience, rather than pure data, leads me to believe that what happens after paid leave is nearly as crucial—that is to say, what happens when Mom and Dad return to the office. We need to normalize the experience of parenting while working.    

President Donald Trump can only escalate. He cannot help it.

On Thursday night, he spread from his own presidential account a video of the speaker of the House, edited to splice together moments when she stumbled over her words, in an apparent effort to deceive people into thinking her drunk or ill. In 2016, Trump’s Russian supporters performed this service for him with faked videos of Hillary Clinton. Now he seems to have decided that if you want a dirty-tricks campaign done right, you must do it yourself.

At the same time, he has put the declassification powers of the presidency to work as part of a larger campaign of cover-up.

Trump directed his attorney general to declassify documents in an effort to depict Trump’s campaign as a victim of improper surveillance in 2016. Trump tweeted that the attorney general had “requested” these powers. That may even be true. But Trump has been demanding such an investigation of U.S. intelligence agencies since long before William Barr got the top law-enforcement job. Barr is compliant and complicit, but the idea is all Trump’s.

If “I told you so” had a sensation, it would be the sweet cocoon of an 80-degree workspace. For years, women have been saying that the AC is on too damn high. We’ve dragged not one but two sweaters to the office in the summer: one for our slowly numbing legs, and one for our shivering shoulders. Scientific studies have already shown that offices are set for men’s frostier preferred temperatures.

Now a new paper confirms what many of us have long suspected. Women don’t just prefer warmer office temperatures. They perform better in them, too.

For the study, published today in the journal PLOS One, the researchers Tom Chang and Agne Kajackaite had 543 college students in Berlin take different types of tests in a room set to various temperatures between 61 and 91 degrees Fahrenheit. First, the participants had to answer logic problems, like the one about a bat costing $1 more than a ball. Then, the students were asked to add up two-digit numbers without a calculator. Finally, they had to form German words out of the letter scramble ADEHINRSTU.

Uber is now a massive, publicly traded company. Anyone can buy Uber shares at a valuation of about $70 billion. This isn’t bad for a company losing billions of dollars a year, but it’s a fraction of the $120-billion valuation the IPO’s bankers initially floated. It’s roughly what private investors valued it at 3 years ago, when the company made $7.43 billion less revenue.

That is to say, there’s a large gulf between how venture capitalists saw the company and how a broader set of investors on the public market see it. Journalists and analysts have tried to explain this yawning gap. Maybe it’s because Uber stayed private too long, or because Lyft messed up ride-hailing IPOs, or because the timing was bad, or because the long shadow of corporate misbehavior has tarnished the brand. With $50 billion on the table, there’s plenty of blame to spread around.

When Game of Thrones ended its eight-year run on Sunday, the series finale, titled “The Iron Throne,” received a largely negative critical response. Many writers pointed out that the show’s last season had given up on the careful character-building of Thrones’ early days—a problem that, in truth, had started a few years back. The result was a seemingly rushed conclusion where multiple characters made poorly justified decisions and important story lines felt only halfway developed.

The show made plenty of mistakes in its final episode, but among the most significant was Thrones’ abrupt and uncharacteristic turn to moralizing—and its use of heavy-handed allusions to 20th-century history to do so. Characters who were once morally complicated, whose actions fit within well-developed personal motivations and fueled the show’s gripping political drama, became mechanisms to bring the story to a hasty, unearned conclusion. Characters like Daenerys Targaryen and Tyrion Lannister—previously complex and fully formed—became, in “The Iron Throne,” mere tools in the service of a plodding message about the dangers of totalitarianism.

Every so often a tweet breaks out of its social medium, and finds its way to Instagram and Facebook. On Wednesday, the tweet spreading across the internet came from Burger King.

got student loans? what's ur $cashtag?

— Burger King (@BurgerKing) May 22, 2019

Either Burger King was saying that it was going to send money to student borrowers using CashApp, a mobile payment service (a $cashtag is its version of a username), or the fast-food giant was trolling all 92,000 people who responded to the tweet. Some of the responses to the Whopper purveyor were in jest, others seemingly genuine, but everyone wanted to know: Is anyone actually getting any money?

On Thursday, Burger King provided an answer. An ad showed a white screen overlaid with a jarring statistic in slime green as “Pomp and Circumstance”— you know, the “graduation song”—plays. “65 percent of students enter the world with student debt,” it says. Then, in an abrupt transition, the Burger King “King” appears swinging a flamethrower like Michael B. Jordan in Fahrenheit 451. “Your student debt goes here,” a caption bubble reads.
