CHICAGO—The midterms are done, and Barack Obama is trying to get back to his post-presidency. He still thinks the country and the world are broken, but he’s dropping back out of the public debate, urging those who came to his foundation’s second annual summit here on Monday that they need to pick back up the charge for change.

“You literally can remake the world right now, because it badly needs remaking,” Obama said.

The answers to fixing problems in agriculture, education, sustainable energy and other fields, he said, aren’t as complicated as they’re made out to be. But, he insisted, “the reason we don’t do it is because we are still confused, blind, shrouded with hate, anger, racism, mommy issues.”

These should be boom times for sex.

The share of Americans who say sex between unmarried adults is “not wrong at all” is at an all-time high. New cases of HIV are at an all-time low. Most women can—at last—get birth control for free, and the morning-after pill without a prescription.

If hookups are your thing, Grindr and Tinder offer the prospect of casual sex within the hour. The phrase If something exists, there is porn of it used to be a clever internet meme; now it’s a truism. BDSM plays at the local multiplex—but why bother going? Sex is portrayed, often graphically and sometimes gorgeously, on prime-time cable. Sexting is, statistically speaking, normal.

“I want them to talk about racism every day,” Steve Bannon, President Donald Trump’s former strategist, told The American Prospect last year. “If the left is focused on race and identity, and we go with economic nationalism, we can crush the Democrats.”

Bannon was tapping into an old American tradition. As early as the 1680s, powerful white people were serving up racism to assuage the injuries of class, elevating the status of white indentured servants over that of enslaved black people. Some two centuries later, W. E. B. Du Bois observed that poor white people were compensated partly by a “public and psychological wage”—the “wages of whiteness,” as the historian David Roediger memorably put it. These wages pit people of different races against one another, averting a coalition based on shared economic interests.

Over the past few years, an international team of almost 200 psychologists has been trying to repeat a set of previously published experiments from its field, to see if it can get the same results. Despite its best efforts, the project, called Many Labs 2, has only succeeded in 14 out of 28 cases. Six years ago, that might have been shocking. Now it comes as expected (if still somewhat disturbing) news.

In recent years, it has become painfully clear that psychology is facing a “reproducibility crisis,” in which even famous, long-established phenomena—the stuff of textbooks and TED Talks—might not be real. There’s social priming, where subliminal exposures can influence our behavior. And ego depletion, the idea that we have a limited supply of willpower that can be exhausted. And the facial-feedback hypothesis, which simply says that smiling makes us feel happier.

In the east of Brazil, mysterious cones of earth rise from the dry, hard-baked soil. Each of these mounds is about 30 feet wide at its base, and stands six to 13 feet tall. From the ground, with about 60 feet of overgrown land separating each mound from its neighbors, it’s hard to tell how many there are. But their true extent becomes dramatically clear from space.

Using satellite images, Roy Funch from the State University of Feira de Santana has estimated that there are about 200 million of these mounds. They’re arrayed in an uncannily regular honeycomb-like pattern. Together, they cover an area roughly the size of Great Britain or Oregon, and they occupy as much space as the Great Pyramid of Giza 4,000 times over. And this colossal feat of engineering is, according to Funch, the work of the tiniest of engineers—a species of termite called Syntermes dirus, whose workers are barely half an inch long.

Last Saturday night, a Fox News contributor named Kat Timpf was at a bar in Brooklyn. As she recounted the incident to National Review, a man asked her where she worked. A while later, she said, a woman began “screaming at me to get out.” Timpf walked away, but the woman followed her around the bar while other patrons laughed. Fearing physical attack, Timpf left. She told National Review and The Hill that it was the third time she has been harassed since 2017. A few months earlier, a woman yelled at her during dinner at a Manhattan restaurant. The year before, while she was about to give a speech, a man dumped water on her head.

Protests like these, that target people’s private lives, are wrong. They violate fundamental principles of civil disobedience, as understood by its most eminent practitioners and theorists. And they threaten the very norms of human decency that Trump and his supporters have done so much to erode.    

I first felt reality shift when, at 7 a.m. on a Saturday, there was a line for a class called Body Blast Bootcamp, and I worried that there wouldn’t be enough room for everyone.

The draw to this explicitly not-fun undertaking, others in line told me, was that we would be glad to have done it when it was over. We all made it in, and the workout studio was a carpeted conference room where an Instagram-famous instructor with a microphone headset was waiting to give us high fives. “The hardest step is showing up!”

Once we started working out, a person walked around apparently taking Instagram videos, and people were not bothered by this. Another brought a mini tripod to get some shots of herself in action. There was shouting and a Coldplay house remix. Someone offered me a box of alkaline water, and I drank it because no neutral water was available.

Last week, the NRA kept defending gun rights, the AARP kept advocating for older Americans, and the California Avocado Commission was as steadfast as ever in touting “nature’s highest achievement.” By contrast, the ACLU issued a public statement that constituted a stark, shortsighted betrayal of the organization’s historic mission: It vehemently opposed stronger due-process rights for the accused.

The matter began when Secretary of Education Betsy DeVos put forth new guidelines on how to comply with Title IX, the law that forbids colleges that receive federal funding to exclude any students, deny them benefits, or subject them to any discrimination on the basis of sex.

The most controversial changes concern what happens when a student stands accused of sexual misbehavior. “Under the new rules, schools would be required to hold live hearings and would no longer rely on a so-called single investigator model,” The New York Times reports. “Accusers and students accused of sexual assault must be allowed to cross-examine each other through an adviser or lawyer. The rules require that the live hearings be conducted by a neutral decision maker and conducted with a presumption of innocence. Both parties would have equal access to all the evidence that school investigators use to determine facts of the case, and a chance to appeal decisions.” What’s more, colleges will now have the option to choose a somewhat higher evidentiary standard, requiring “clear and convincing evidence” rather than “a preponderance of the evidence” in order to establish someone’s guilt.

The Halifax Security Forum is designed to be a gathering of the world’s democratic countries, which are allied to protect each other. Hosted by the Canadian defense minister, the Forum’s signature is the brief videos that introduce the annual gathering. This year’s intro showed relay runners, mostly American, at the Olympics from Berlin in 1936 forward, ending in an uncertain baton handoff—a powerful metaphor for the free world’s worries about American leadership in the age of Trump.*

The Halifax Forum, occurring just after President Donald Trump unleashed yet another petulant tirade against Germany and France that culminated in the unseemly taunt that Parisians were speaking German until the U.S. intervened in World Wars I and II, had a funereal feel this year. Allies are grieving the loss of an America they believed in, as it sinks in that they cannot rely on us any longer.

Nearly 45 years ago, the House Judiciary Committee concluded that President Richard Nixon’s contact with high-level Justice Department officials overseeing the Watergate investigation, detailed in a 62-page “road map” of evidence collected by prosecutors between 1972-1973, amounted to an impeachable misuse of executive power.

Half a century later, the FBI’s former top lawyer, Jim Baker—a close friend and associate of fired FBI Director James Comey—is laying out parallels, albeit subtly, to President Donald Trump’s interactions with the law enforcement officials who have been investigating him and his campaign team since July 2016.

In a piece for Lawfare published on Monday, Baker used the newly unsealed Watergate road map to show how one president’s attempts to control an investigation targeting him and his associates were quickly exposed and, ultimately, used against him. As the road map laid out, Nixon interacted regularly with the man supervising the Watergate investigation—Henry Petersen, then the assistant attorney general for the Justice Department’s Criminal Division—and pumped him for information.
