Editor’s note, August 9, 8 am ET: We’re bringing you some of our best-loved Your Mileage May Vary columns while Sigal Samuel is on parental leave. The one below was originally published in April.

This unconventional advice column offers you a unique framework for thinking through moral dilemmas. It’s based on value pluralism: the idea that each of us has multiple values that are equally valid but that often conflict with each other. Submit your own question here.

---

I’m trying to decide whether to keep my elementary school-age kid in the neighborhood public school or move him to a more exclusive private school. Our public school is okay, but my partner and I feel that he might be more challenged and ultimately better off moving to a private school.

But I’m very aware of the increasing flow of students around the US out of public schools, and the effect that is having on the children who remain there. For one thing, since public schools get more funding the more students they have, every family that leaves effectively takes money with them. I worry that by taking my child out of public school, I’m contributing to that problem, but I also don’t want my child to bear the personal burden of my politics.

Dear Public School Parent,

The way you’ve framed the question makes it sound like keeping your kid in public school means imposing a burden on him. And if that were the case — if we really were talking about sacrificing your child’s well-being — I know exactly what I’d tell you.

I’d tell you not to be bullied by utilitarian philosophers. They argue we have to consider everyone’s well-being equally, with no special treatment for our own kids, so they’d probably say it’s wrong to give your child a fancy education while consigning other children to a school with fewer resources. But the 20th-century British philosopher and critic of utilitarianism Bernard Williams argues that this sort of total impartiality is an absurd demand — and I agree.

Williams points out that moral agency — the capacity to act on values and commitments — always comes from a specific person. And as specific people, we have our own specific, individual, core commitments. These “ground projects,” as Williams calls them, are the commitments that give a life its meaning and continuity. A parent has a commitment to ensuring their kid’s well-being, over and above their general wish for all kids everywhere to be well. Williams would say any moral theory that requires you to ignore such personal commitments severs you from the very things that make your life recognizably yours.

So if keeping your kid in public school really meant hurting him, I wouldn’t say you have to do it.

But you said your neighborhood school is okay. It sounds like it’s not bad and not unsafe. So I don’t have reason to think that it is actually hurting him. In fact, it might be helping him in ways you’re not fully accounting for. 

Education is complicated. If I were to get into all the details about school choice and vouchers and charter schools and magnet schools, I’d have to write a whole book. So let me just stick to the main points relevant to your dilemma, starting with this: There’s a popular narrative that says private schools are better than public schools, but the evidence does not support that — especially if we take a broad look at what we mean by “better.”

Although studies do show private school students outperforming their public school counterparts on tests, the studies also show that private school advantages disappear mostly or entirely once you control for family background. 

Longitudinal research led by Robert Pianta and Arya Ansari at the University of Virginia tracked more than 1,000 children from birth to age 15 in 10 locations nationwide. After controlling for family income, parental education, neighborhood socioeconomic makeup, and other background variables, the private school advantage…vanished.

“If you want to predict children’s outcomes — achievement test scores, the things we care about socially — in high school, the best thing you can use to predict that is going to be family income — regardless of what high school you go to,” Pianta said.

Pianta’s was a modest-sized study with some methodological limitations. But another analysis of two large, nationally representative datasets also found that public school kids did just as well in math as private school kids — or even outpaced them — after accounting for demographic differences. (Math is considered a particularly robust indicator of school quality writ large because, unlike reading, it’s a subject learned mostly at school and not at home.) The researchers suggested that might be because public school teachers have to do stricter certification and can be required to do more frequent professional development, so they may be more reliably up-to-date on the latest pedagogical approaches, like those developed by the National Council of Teachers of Mathematics.  

Admittedly, the very fanciest of private schools do offer some special advantages. Network effects are real. Maybe you want your kid rubbing elbows with a future senator. And maybe if you send your kid to ultra-elite Andover or Exeter, he’ll have a leg up if he applies to a fancy private college. 

But that is not the same as ensuring your child actually thrives. I’m sure you also care about your child’s psychological well-being. And here, some of the evidence about exclusive, high-achieving schools is worrying. 

The most important educational institution in your kid’s life is you.

The unrelenting pressure to compete and achieve can be brutal in those schools. When students constantly compare themselves to others and peg their self-worth to achievement, the results are alarming. Studies conducted over decades by psychologist Suniya Luthar and colleagues found that students attending high-achieving schools are at significantly higher risk for anxiety, depression, and substance use. (These are often private schools, though hyper-competitive public schools can also fall into this trap.) In fact, the National Academies of Sciences now names these students an “at-risk” group for mental health problems, alongside kids who live in poverty or in foster care or who have incarcerated parents.

In addition to potentially providing a less stressful environment, public schools can confer other important advantages. For one thing, your local public school can help you and your child be part of the neighborhood community, which is incredibly valuable for social development and countering loneliness. And being in an environment that’s more diverse in terms of race, ethnicity, or class can teach your kid to empathize and get along with a wide variety of people. 

As the American philosopher John Dewey pointed out, these are essential skills and capacities for a flourishing adult life and for a flourishing democracy. Democracy is a way of being in community with people unlike yourself; that’s a mode of life that has to be cultivated, and public schools are great grounds for learning to navigate a shared world.

Plus, public education is free! (Well, “free” — you’ve already paid for it with your taxes, whether or not your kid uses it.) So you could save all the money you’d spend on private school and instead use it on enriching opportunities to expand your child’s horizons. Personally, I’d take my kid to Italy and teach them about Ancient Roman gladiators and Renaissance art and the many flavors of gelato! Or you could collaborate with your child to decide where to donate some of that money to fund education resources for kids elsewhere. 

On balance, since the evidence suggests that a child at a decent public school, with involved parents, probably won’t gain meaningful advantages from switching to an exclusive private school — and may face real psychological risks in a hyper-competitive environment — I don’t see a compelling reason to make the move. If you’ve got the resources to even consider private school, then your home life will probably play the biggest role in your kid’s academic trajectory, regardless of which building he sits in during the day. The most important educational institution in your kid’s life is you.

That said, I’m not arguing that parents should never pick private school. To some extent, this depends on the unique needs of your kid and your family. Maybe your kid is absolutely in love with music and the private school nearby has an amazing music program. Maybe your kid is being bullied at his current school but has a couple great friends who attend the private school. Or maybe a religious education is very important to you, so a private parochial school makes sense. 

If you do make the choice to send your kid to private school, you’ll have to grapple with the collective action problem you hinted at: Any single family’s departure from a public school barely registers, but when every family with options reasons the same way, the cumulative effect on the school’s funding — and on the kids who remain — can be devastating.

Here, the American political philosopher Iris Marion Young can help you. She points out that our usual model of responsibility — the “liability model,” which says that when something bad happens we should assign blame to a particular individual — is inadequate when we’re dealing with situations of structural injustice. In these situations, it’s a whole system that’s producing predictable patterns of disadvantage. 

Just look at the complex web that breeds educational inequality: Historical housing segregation has concentrated poverty in certain neighborhoods. Poorer neighborhoods generate less property tax revenue, which means less money for local schools. States can try to offset that, but schools in poorer areas still tend to end up with fewer resources. Families with options leave for better-resourced schools, enrollment drops at the local public school, and the school loses even more funding. The kids who remain get less of the materials — from textbooks to counselors — that would have set them on the path to success. There’s a clear downward spiral, but no one person or decision is the villain.

So instead of blaming any one individual for their personal lifestyle choices, Young says that in cases of structural injustice, we should adopt the “social connection model” of responsibility. Under this model, you don’t bear blame if you send your kid to private school, because systemic problems shouldn’t rest on one family’s shoulders. Young doesn’t think you need to discharge your obligations through personal lifestyle choices. 

But that doesn’t mean you owe nothing. 

You do still have a political obligation: to work toward changing the structure that produces injustice. As a participant in the political system that shapes education in this country, you have some power to act on it. You can vote and organize and advocate. You can pressure decision-makers and support reform movements. The more power you’ve got, and the more privileged you are by the current system, the greater your obligation to take action.  

Make the effort to act on that obligation. Let your child watch as you do. Better yet, involve them in the process. Kids learn from seeing what their parents do: Show them that you’re bent on enacting your values, and you’ll be giving them an education for life.

Bonus: What I’m reading

• This is a fun piece in Asterisk about how high-school science fairs have become so ridiculously competitive that they no longer give students a chance to do real independent research.
  
• This week’s question prompted me to listen to the podcast series “Nice White Parents.” It’s a fascinating look at what happens when parents think that choosing public school would mean sacrificing their child’s prospects on the altar of their own political ideals. Spoiler: Practically no parent is willing to sacrifice their own child. But they often don’t realize they’ve constructed a false trade-off.
  
• Living life requires making choices. It’s unavoidable that we’ll feel regret about some of the paths not traveled. But this Aeon essay explains how “living in closer alignment with our values and authentic preferences may help us avoid the worst pain of regret.”

Of all the extinction-level threats vying for our attention, AI, climate change, and nuclear war tend to get most of the airplay. But Annie Jacobsen thinks biological war should be near the top of our mental list of doomsday scenarios, too.

She should know — Jacobsen has carved out a unique niche as America’s foremost reporter on the ways we could end the world. Her bestselling 2024 book Nuclear War: A Scenario terrified readers and experts alike, and has been optioned by Hollywood. 

It was while conducting dozens of interviews with high-level government sources for Nuclear War that Jacobsen was told repeatedly that biowarfare should be her next focus.

She took their advice. Her gripping new book Biological War: A Scenario follows a similar ticking-clock format that shows, step by step, just how a humanity-threatening man-made biological catastrophe could play out. (Spoiler alert: not great.)

The result feels like dystopian science fiction, albeit the kind that comes heavily footnoted with government studies that come to similarly grim conclusions. The fact that tech CEOs are also sounding the alarm that advanced AI could make creating killer germs even easier only adds to the growing sense of anxiety. And this book has also been optioned by Hollywood for a TV adaptation. 

Jacobsen sat down with Today, Explained host Noel King to talk through the plot of her nightmare scenario, why we’re still developing biological weapons despite the clear risks, and what needs to happen to avoid disaster. Below is an excerpt of their conversation, edited for length and clarity. There’s much more in the full podcast, so listen to Today, Explained wherever you get podcasts, including Apple Podcasts, Pandora, and Spotify.

How does your book start?

The inciting incident in the book is an accident at a Biosafety Level 4 lab, shorthand BSL-4, in Siberia called Vector. And it’s an actual BSL-4 lab, the highest classification. … And there was an actual accident, an explosion there in 2019. 

In that real-life incident, a deadly pathogen was not released that we know of. But of course, in Biological War: A Scenario, a deadly pathogen is released. And it’s a form of pneumonic plague, which is a nightmare pathogen and sits at the top of the Tier 1 select agent list of the CDC. And so in the first act of the book, I show the scrambling of the intelligence community and the Defense Department, trying desperately to determine if something got out and what it is. … The release of the pathogen widens, and so once you have escape. You do not have mitigation, which has to happen in the first 24, 48 hours. Now you have a situation which is unstoppable.

You say this is now an unstoppable scenario. What is it?

A plague itself, of course, conjures up images and ideas of the bubonic plague of the 14th century, the Black Death. That killed between one half and one third of Europe. The bacteria is called Yersinia pestis. And pneumonic plague is the airborne version of plague. The problem with an airborne pathogen is that because the delivery system is the human lungs, it can move very quickly from a scientist in that lab who now has Yersinia pestis in his lungs out to the general public. And that is precisely what happens in the scenario.

How does it spread from there? The city where this BSL-4 lab sits isn’t Moscow. What happens once the pathogen is in the lungs of the people who work in that lab, or the janitor who was cleaning it that night?

That’s right. Well, suddenly it’s in everyone’s lungs, and those people go out into their community. And even though Koltsovo, the science town where Vector is located, is a small town, it is just 12 miles from Novosibirsk, which is the third-largest city in Russia. And, also, there happens to be in this scenario a group of international hunters on a hunting trip in that area who come across a dying scientist in the snow. One of them gives him CPR, being the Good Samaritan that he is. And lo and behold, those travelers suddenly are now getting on an airplane in Novosibirsk, flying home to where they reside in five or six of the continents.

What makes this form of plague so novel, so dangerous?

I pull this information from actual facts of the Soviet Cold War-era biological weapons program that we know about from Soviet defectors. And I want you to keep in mind: This is 40 years ago when gene editing was in its infancy. But there are two things specifically that the Soviet bioweapons engineers did to plague. 

Their idea was to create a super plague weapon. And one of them has never been revealed before. They were working to insert the gene for euphoria into the plague pathogen. … When you get a disease, a pneumonic-type disease, pneumonia, tubercular, you want to go home and get under the covers because you feel terrible. And when you do that, you’re infecting a lot less people than you would if a gene for euphoria had been inserted into the pathogen, which would make you feel terrific, which would make you want to go out and socialize with people, perhaps even go to a crowded disco. 

And the other thing that the Soviet scientists were working on was a way to defeat medical countermeasures, but with an added component of psychological distress. They inserted a gene into the pathogen that would be triggered by the taking of antibiotics. And that second pathogen would give you encephalitis, which is a swelling of the brain. The psychological part of it, according to the Soviet scientists, was that they wanted the last thought of the person dying of what they thought was pneumonic plague, but would in fact be encephalitist to be, “My government and Western medicine has failed me.”

Those of us who try to remain optimistic think there’s a way to stop it. In the movies, there’s an outbreak, then the government gets it under control, and okay, maybe a lot of people die, but we’re all right. That is not where your book is headed. How does your scenario end?

So in the book, I take readers from outbreak to anarchy in six days. Anarchy is what will happen according to Pentagon war gaming and pandemic planning. And this is because fear of infection becomes a secondary weapon, if you will. People begin to behave like they are about to die, which is most certainly underpinning everyone’s mind. And so after those first six days, the Principals Committee, the President’s Biodefense Committee, must make a decision. The president has to declare the Insurrection Act, which allows the military to step in as a law enforcement agency. 

“Imagine the president — with a few Secret Service outside the door, the military aide with the nuclear football — sitting alone in a room wearing a gas mask.”

What happens to the president really blew my mind as a reporter. He goes somewhere in the United States very far away from everyone. Because the idea, the goal, is to make sure that the president doesn’t get the airborne pathogen in his lungs. So maybe I’ll leave you with an image. Imagine the president — with a few Secret Service outside the door, the military aide with the nuclear football — sitting alone in a room wearing a gas mask.

In the book, the people who survive are the ones who have gas masks. Everyone else is gone.

And look, we hope we never get to that, by all means. But yes, the Pentagon has issued 1.7 million gas masks to its military personnel. And that is a spooky thought in and of itself, coupled with the idea that the military is predominantly male. There’s something like 17 percent women in the military. And so, unlike the Nuclear War scenario in which I had science-based nuclear winter theory to work from, in Biological War, nothing has been written on the science record about what it might be after. And so the one imaginative part of the book is the very end where I write about biological twilight. … And it is a very, very ugly world.

Let’s back up. We did outlaw biological weapons at some point, right?

That’s right. Very mysteriously in 1969, President Nixon just unilaterally declared that the arsenal was going to be destroyed. At the same time that all of the nations of the world were working to sign this treaty called the Biological Weapons Convention Treaty, which would outlaw bioweapons. Soviet Russia at the time signed it but immediately began work on an illegal biological weapons program that was colossal. And this went without notice, without any idea really by the CIA and the Pentagon all the way until 1989, when one of the Soviet scientists named Vladimir Pasechnik had a crisis of conscience and he defected and he told British intelligence all about the program.

Where have we seen biological weapons used?

Maybe the most important example of a biological attack in the past, certainly here in the United States, are the anthrax attacks, which occurred right after 9/11. Weaponized anthrax was sent through the mail to US senators and a number of media outlets. So five people ended up dying; 22 got sick in four states. But that really kicked off what can be considered the biological military-industrial complex, if you will, which led to this buildup in BSL-4 labs around the world today. There are 110 BSL-4 labs around the world. There are more than 3,500 BSL-3 labs.

Your book has a map of where those labs are, which I found weirdly comforting, mainly because I don’t live too near any of them. If one of these things is going to be released, either accidentally or deliberately, where is the threat coming from? A rogue nation? Terrorists?

Certainly, bad actors getting a hold of a biological weapon was the great concern of the post-anthrax situation. And that is why so much emphasis was put on bioterrorism. Now I avoided that specifically in the book. … And I didn’t even have an attack. Rather, I had an incident. I had a lab leak because I have learned in the decades since that really is the greatest concern. So many of these BSL-3 and 4 labs are in places without a lot of security, including in countries where there are wars going on.

Could somebody be making a biological weapon in a basement somewhere, off books?

Absolutely. And another disturbing document I came across, unclassified in the Pentagon, was a threat spectrum that showed weapons of mass destruction in terms of destructiveness. And of course, nuclear weapons sit at the far end of the spectrum. They are the most destructive. But very close behind were biological weapons. And even more startling was the notion that biological weapons present the greatest overall threat. 

Nuclear weapons have an extremely high barrier for entry. You have to have fissile material. … You have to have a weapons delivery system like an ICBM or a submarine. … That creates a situation where most nuclear weapons, all nuclear weapons, if you will, are in the hands of a command-and-control system within a nation. 

Biological weapons have no such barriers. In fact, the barriers for entry are getting lower literally by the day. You now can have a situation where someone with very limited knowledge of biology can create a biological weapon in their basement with the use of computational systems like an AI system, for example.

Your book reads like a thriller. How much have you exaggerated? How much have you novelized in order to hold our attention?

Everything in the book is based in science fact, meaning all of the facts, all of the figures. I write a hundred or so pages of notes in the back of the book for readers to be able to answer the question that you are asking me. … In the notes, you can find that answer.

Did any of those people give you good recommendations for how to avoid a disaster scenario, or at least how to avoid these things proliferating?

Well, you know, the ticking clock scenario that I write has an even more urgent ticking clock, which is the public’s pressure on lawmakers to absolutely do something about this nightmare scenario before it happens. Look, we have a world right now where you have the CEOs of the largest AI companies in the world admitting publicly that the lane of bio mixed with AI is of their top concern. You don’t hear that about nuclear. You hear that about bio.

How do you sleep through the night?

Anyone who knows me personally can vouch for the fact that I am an optimist at heart. I really believe that information is king. Once you know things, it gives you a lot of power. Perhaps that’s whistling by the graveyard, but that’s what works for me.

Do you have a biohazard suit?

I do not. I do not. But I do have a few gas masks. I must tell the truth.
