The 1964 Supreme Court Case Jacobellis v. Ohio presented a highly subjective question to the justices: what is obscenity or pornography? How do you define it? Where do you draw the line? In response, Justice Potter Stewart gave us the iconic line, "I know it when I see it."
His ambiguous answer works fine for humans who can make judgement calls on the fly, but the algorithms that rule our lives need rules that are much more concrete. Say you flag something as inappropriate on social media. How is artificial intelligence meant to answer a question that even the Supreme Court could not definitively pin down?
Thatâs where humans come in. Mary Gray, an anthropologist and co-author of the book,âGhost Work: How to Stop Silicon Valley From Building a New Global Underclass,â explores the work and lives of the real people behind online processes that internet users may assume are purely algorithmic. From analyzing medical tests, to flagging questionable social media posts, to identifying your rideshare driver, Gray argues that the human touch of âghost workâ is not only essential, but this hidden workforce will continue to keep growing.

We have become accustomed to politicians shouting at each other, and confrontational TV talk show hosts who do anything but listen to their guests, but how good are any of us at truly focusing on the words of others in our conversations?
Listening is a lost art, according to Kate Murphy the author of âYou're Not Listening: What You're Missing and Why It Matters,â and the cost to our health, our relationships, and our society is steep, she says. Murphy explains how the modern world has shaken our capacity for deep listening and what we can do about it.

Childhood today is radically different than it was just a few generations ago. Before the coronavirus pandemic, kidsâ busy schedules included school, homework, chores, sports, music lessons and other activities. Those packed schedules often left out one key element that is crucial to growth and learning â play. Thatâs according to Dorsa Amir, a postdoctoral researcher and evolutionary anthropologist at Boston College.
Amir has studied the Shuar people of Ecuador, a non-industrialized society, and observed startling differences in how Shuar children and American children spend their time. She tells us how childhood has changed drastically, and how that affects kids today.

In 2019, women hit a milestone in gender parity when they became the majority of the college-educated workforce. While it may be easy to see how this âachievement will impact the economy, earnings, and job opportunities, it is probably a little bit harder to predict how it will shape, of all things, the dating market. Jon Birger, a business journalist and former senior writer at Fortune, has authored two books on the connection between ratios and relationships. Birger acknowledges that not everyone has a desire to engage in a heterosexual relationship or get married. But of those who do, college-educated women may have a particularly hard time finding a partner, he notes.
Birger says this is because there are many fewer men enrolled in college - about 60% of college freshmen are now women. Men also drop out of college at higher rates, resulting in a dating market with a shortage of college-educated men. When this gender asymmetry is extended into broader society, Birger explains it can have significant consequences for peopleâs happiness, fertility rates, and the economy. And Andrew Cherlin, a professor of public policy at Johns Hopkins University, talks with us about his - related - new research on changing marriage rates for college and non-college educated Americans.

Exercise is a relatively recent phenomenon. After all, itâs difficult to imagine a caveman on a treadmill. And itâs safe to say that paleolithic humans never pumped iron. But something changed as we moved from the plow to the Peloton. Exercise - physical exertion for the purpose of improving health or fitness - became a huge part of modern life, and a nearly $100 billion global industry.
But why do we spend so much time and money at the gym or on the track and does it actually help our well-being? And why is exercise, at least for some of us, such a miserable experience?
Daniel Lieberman, professor of human evolutionary biology at Harvard University and author of the book âExercised: Why Something We Never Evolved to Do Is Healthy and Rewarding,â has some fascinating answers.

In the decades since Roe v. Wade, public sentiment about abortion has remained fairly steady. By contrast, in the mid-1990s, only around a quarter of the country supported gay marriage, and then, somehow, just 15 years later, those numbers had nearly doubled. Sasha Issenberg, author of âThe Engagement: Americaâs Quarter-Century Struggle Over Same-Sex Marriage,â tracks the twists and turns that the fight for same-sex marriage in America took, from a power struggle over a parade in Hawaii, to shifts in elite opinion, which all brought gay marriage from a âquirky,â niche issue in the 90s to being federally accepted by 2015.

The U.S. economy has come a long way since the darkest days of the pandemic, but the future remains uncertain for many, especially those hit the hardest: low-wage workers. Last April, David Autor, an MIT economist, predicted that a pandemic-induced recession would be an âautomation forcing event,â with executives rapidly deploying non-human labor to replace workers, particularly in the service sector - and he was right.
Autor and Betsey Stevenson, who served as chief economist at the U.S. Department of Labor and is currently a professor of economics and public policy at the University of Michigan, discuss COVID-19âs long-lasting impact on the ways employees will work, consume and manage family dynamics, for years to come.

About 1500 years ago, the world was a very different place; Pope Gregory was spreading Catholicism far and wide, a plague was running rampant, and some dominoes were about to start falling. The end of that cascade would end up in a world where a certain group of people started to think quite differently from those who had come before them. Their brains began to change, the societies they built thrived and they grew so influential and culturally dominant that their way of thinking permeated our entire psychology. In other words, it created W.E.I.R.D. people â a Western, educated, industrialized, rich, and Democratic population that grew into a global powerhouse.
Thatâs according to Joseph Henrich, chair of the department of human evolutionary biology at Harvard University, and author of âThe WEIRDest People in the World: How the West Became Psychologically Peculiar and Particularly Prosperous.â He writes that people who learn to read, who are educated in a Western way â no matter where they live in the world â have brains that look and think unlike more traditional human brains.

Walter Isaacson has made a habit of profiling world-changers: innovators who, through their discoveries, upend the way we live. Recently, heâs been preoccupied with individuals who have unlocked what he calls âfundamental kernels of our existenceâ - first Albert Einstein and the atom, then Steve Jobs and the bit, and now, in his latest work, Jennifer Doudna and the gene.
In The Code Breaker, Isaacson dives into the CRISPR revolution and how the booming field of gene editing is altering how we treat disease and think about what it means to be human. Jennifer Doudna, who shared the 2020 Nobel Prize in Chemistry for her role in developing CRISPR, is Isaacsonâs centerpiece as he guides readers through this new frontier, and the pressing moral questions that sophisticated, cutting-edge biological tools now pose.

Educators around the country were plunged into a massive experiment with virtual learning last year, when more than 50 million K-12 students were sent home at the start of the pandemic. Many were soon knocking on the door of the father of online education, Sal Khan, looking for help. The founder and CEO of the nonprofit Khan Academy, which provides free educational resources to anyone who wants them, says he was impressed with the âheroic effortsâ of numerous school districts to close the digital divide, by providing device and internet access for all who needed it. Now Khan hopes school leaders âare going to be thinking long-termâ and will seize the moment to create what he considers much needed system-wide change.

All over the country, school districts are grappling with how to safely reopen classrooms in the midst of a resurgent pandemic. While many have already made decisions about in-person learning, state and local governments are clashing over mask mandates and vaccination requirements. Edward-Isaac Dovere, a staff writer for The Atlantic and author of âBattle for the Soul: Inside the Democrats' Campaigns to Defeat Trump,â discusses the political and practical implications of such divergent reopening policies.

It has been said that cleanliness is next to godliness, but the constant disinfecting and scrubbing of our homes, offices and public spaces during the coronavirus pandemic has taken these seemingly virtuous efforts to a whole new level.
COVID-19 is now understood to spread primarily through close contact with infected people, rather than contaminated surfaces, but that hasnât stopped consumers from snapping up cleaning products that promise to kill 99% of germs.
Trying to eliminate all bacteria, including those that are beneficial to us, can lead to autoimmune disorders, warns Rob Dunn. The professor of Applied Ecology at North Carolina State University and author of: âNever Home Alone: From Microbes to Millipedes, Camel Crickets, and Honeybees, the Natural History of Where We Live,â explains how we can be more intentional about our interactions with the living world (indoors and outdoors) and better understand its influence on our well-being.

Imagine a crime scene, and what it might take to solve the case. Do you think about dusting for fingerprints? DNA collection? According to Kate Winkler Dawson, author of âAmerican Sherlock: Murder, Forensics, and the Birth of American CSIâ and associate professor of journalism at the University of Texas at Austin, the man we can thank for that approach is Edward Oscar Heinrich. In the early 20th century, Heinrich took the world of forensics from guesswork, confession, and coercion to a place of science and nuanced evidence. While some of his experiments have been discredited in recent years as âjunk science,â Heinrichâs impact can still be seen in the way many crime scenes are evaluated today.

Business wonât save the world, but â according to Harvard economist Rebecca Henderson â it can help fix it. Henderson, author of Reimagining Capitalism in a World on Fire, became preoccupied with economics after working for the consulting firm McKinsey & Company where her job was âshutting plantsâ down if they proved unable to adapt to market changes. Since then, Henderson has been animated by the question of how to build a more just and sustainable system.

In Japanese, the word âkaroshiâ translates to âdeath by overwork.â As reports of workplace burnout have skyrocketed since the pandemic, itâs a phrase that aptly encapsulates a feeling that thousands of workers have experienced over the past year. But the issue is neither temporary nor solely catalyzed by the pandemic; instead, we face a long-term health risk with rippling impacts.
This is the argument put forth by Jennifer Moss, a journalist and author of the forthcoming book âThe Burnout Epidemic: The Rise of Chronic Stress and How We Can Fix It.â Moss notes that while burnout has been experienced âsince building the pyramids,â there is something distinct about the current wave of workplace stress plaguing our offices. Technology, a pandemic, and a productivity-oriented work culture have combined to create the perfect storm, she says. âCrisis exacerbates an existing problem. Then what happens is it explodes,â Moss explains. Whatâs more, she says, it is not something that can be addressed simply by âdownstreamâ efforts like office yoga sessions or even a paid week off. Rather, Moss argues, it requires fundamental, institutional change that prioritizes stress prevention over management.

A migration crisis is already underway, and it's caused, at least in large part, by climate change, according to modeling by ProPublica and the New York Times Magazine. Their expert analysis shows that without the proper preparation and political will, it will worsen as soon as 2050. Michael Oppenheimer, a professor of Geosciences and International Affairs at Princeton University, explains how the increasingly deadly combination of heat and humidity is driving people from their homelands. He predicts greater migratory build-ups along the US-Mexico border, in Southeast Asia, and on North Africaâs Mediterranean coast.
Even if we develop a strong response now, a âlack of foresight,â he argues, has brought us to our current reality: a certain level of climate change is already baked into the system for the next 30 years. Oppenheimer says governments must restructure their thinking around climate change to focus not just on emissions, but also extreme weather response.
Plus, we hear from three local reporters at our affiliate stations about the environmental challenges facing their cities. Houston Public Mediaâs Katie Watkins, WJCTâs Brendan Rivers in Jacksonville and KJZZâs Ron Dungan in Phoenix, join us to discuss droughts, flooding, land use, and more.

July 2021 is a big month for Amazonâs Founder and former CEO, Jeff Bezos. Not only did he step down as CEO of the company he built into a $1.63 trillion empire, he will also fly into space on the first crewed flight of his New Shepard rocket ship. And yet, the space trip is just the most recent of Bezosâ boundary-breaking endeavors. Bezos and his company have revolutionized American business, extending their reach into nearly every industryâ from retail, to media, to healthcare, and cloud computing.
Brad Stoneâthe author, most recently, of Amazon Unbound: Jeff Bezos and the Invention of a Global Empireâexplains that the e-commerce giant has often seemed âunbound from the laws of corporate gravity.â While most companies eventually plateau, Stone says that Amazon has defied these business norms by continuing to grow rapidly. Stone, a Senior Executive Editor at Bloomberg News with years of experience reporting on the company, examines Amazonâs various successes and Bezosâ sweeping influence. Specifically, he traces Bezosâ transformation from a frugal tech nerd to a buff billionaire whose high-profile divorce made headlines. But what exactly accounts for Amazonâs extraordinary rise? If there is one thing that drives Bezos, Stone points out, itâs his deep fear of stasis.

The Constitution, first drafted in 1787, stands as the supreme law of the land in the U.S. But Mary Anne Franks â a law professor at the University of Miami who grew up attending a fundamentalist church in Arkansas â says that often âwe read it not as a text but as Scripture,â much in the same way she was taught to read the Bible as a child.
Franks, author of The Cult of the Constitution, argues that originalism â the judicial view that the Constitution should only be interpreted as its writers meant it to be when it became law â has been used to justify ahistorically broad interpretations of both the First and Second Amendments. Rather than claiming âtranscendental accessâ to the foundersâ legal intentions, she proposes we honor the Constitution communally by extending its rights and values to all, including the most vulnerable members of our society.

School is out for the summer, but many students, educators and parents are still reeling from an earthquake in K-12 education. It will take time to recover from learning loss, fractured relationships, stress and other problems caused or exacerbated by the coronavirus pandemic. Nevertheless, as we emerge from crisis mode, some see a chance to transform American education for the better.
Paul Reville, a professor at the Harvard Graduate School of Education, Pedro Noguera, dean of the University of Southern California Rossier School of Education, and Margaret Spellings, former U.S. Secretary of Education for President George W. Bush, dive into the challenges and opportunities that lie ahead. While Sal Khan, founder and CEO of the online learning platform Khan Academy, and a handful of parents consider the possibilities that come with an educational landscape no longer bound by time and space.

Constantly checking your email might feel like textbook responsible work behavior but, according to Cal Newport â a professor of computer science at Georgetown University and author of A World Without Email â it can actually wreak havoc on productivity. Newport argues that our out-of-control inboxes are keeping us from being the thinkers, workers, and problem solvers we could be if email ran our lives less.
