Avoid public transportation when possible, limit nonessential travel, work from home and skip social gatherings. Don’t go to crowded restaurants or busy gyms. You can go outside, as long as you avoid being in close contact with people.

If you develop a high fever, shortness of breath or another, more serious symptom, call your doctor. (Testing for coronavirus is still inconsistent — there are not enough kits, and it’s dangerous to go into a doctor’s office and risk infecting others.) Then, check the Centers for Disease Control and Prevention website and your local health department for advice about how and where to be tested.

Wash your hands, wash your hands, wash your hands. That splash-under-water flick won’t cut it anymore.

Also, clean “high-touch” surfaces, like phones, tablets and handles. Apple recommends using 70 percent isopropyl alcohol, wiping gently. “Don’t use bleach,” the company said.

To disinfect any surface, the C.D.C. recommends wearing disposable gloves and washing hands thoroughly immediately after removing the gloves. Most household disinfectants registered by the Environmental Protection Agency will work.

There’s a lot of information flying around, and knowing what is going on will go a long way toward protecting your family.

Right now, there’s no reason for parents to worry, the experts say; coronavirus cases in children have been very rare. The flu vaccine is a must, as vaccinating children is good protection for older people. And take the same precautions you would during a normal flu season: Encourage frequent hand-washing, move away from people who appear sick and get the flu shot.

Unless you are already infected, face masks won’t helpFace masks have become a symbol of coronavirus, but stockpiling them might do more harm than good. First, they don’t do much to protect you. Most surgical masks are too loose to prevent inhalation of the virus. (Masks can help prevent the spread of a virus if you are infected. The most effective are the so-called N95 masks, which block 95 percent of very small particles.)Second, health care workers and those caring for sick people are on the front lines. Last month, the surgeon general urged the public to stop stockpiling masks, warning that it might limit the amount of resources available to doctors, nurses and emergency professionals.

Stock up on a 30-day supply of groceries, household supplies and prescriptions, just in case.That doesn’t mean you’ll need to eat only beans and ramen. Here are tips to stock a pantry with shelf-stable and tasty foods

No. The first testing in humans of an experimental vaccine began in mid-March. Such rapid development of a potential vaccine is unprecedented, but even if it is proved safe and effective, it probably will not be available for 12 to18 months.

If you’re sick and you think you’ve been exposed to the new coronavirus, the C.D.C. recommends that you call your healthcare provider and explain your symptoms and fears. They will decide if you need to be tested. Keep in mind that there’s a chance — because of a lack of testing kits or because you’re asymptomatic, for instance — you won’t be able to get tested.

That’s not a good idea. Even if you’re retired, having a balanced portfolio of stocks and bonds so that your money keeps up with inflation, or even grows, makes sense. But retirees may want to think about having enough cash set aside for a year’s worth of living expenses and big payments needed over the next five years.

This suggests that the insects understood that “zero” is less than two or three. And they weren’t just going for the empty picture because it was new and interesting

Advanced numerical abilities like this could give animals an evolutionary advantage, helping them keep track of predators and food sources. And if an insect can display such as thorough grasp of the number zero, write the researchers, then this ability may be more common in the animal kingdom than we think.

It’s unclear why this interested the early computer scientist, but Turing had told a friend that he wanted to defeat Argument From Design, the idea that for complex patterns to exist in nature, something supernatural, like God, had to create them.

He just thought mathematics was very powerful, and you could use it to explain lots and lots of things — and you should try

By creating three-dimensional Turing patterns like bubbles and tubes in membranes, the researchers increased their permeability, creating filters that could better separate salt from water than traditional ones.

Fox Island Environmental Education Center, a Virginia institution that has opened up the wonders of the natural world to young people for more than 40 years, shut down in November. Between erosion and sea level rise, so much of the island’s salt marsh had disappeared that “it made it unsafe to run the program,” said Tom Ackerman, vice president for education at the Chesapeake Bay Foundation, which owns the island center.

because south Louisiana’s land is subsiding while the oceans are rising, the region has what may be the highest relative sea level rise in the country. “We’re just 10 to 30 years in front of the curve of everybody else,” he said.

Officials predict that, without action, the lab might need to shut down several dozen days each year within the next 10 to 15 years. The corrosive saltwater attacks the structure and has risen up through the soil into buried electrical cables, at one point causing a blackout. Some floods are accompanied by droves of fiddler crabs that sometimes find their way into the elevators.

Many marine labs are preparing to meet similar challenges, though they are in locations that are not yet facing the level of threat that Louisiana is.

At the Louisiana center, Ms. Conover sees educational value in their problems. Along with its mission as a scientific research facility, it is also a center for environmental education with visits from some 5,000 students each year. “If our parking lot is flooding when a group is here, we definitely talk about why we’re flooding on that given day, when five years ago we wouldn’t, given the same conditions.” That example, she said, “gives the perspective of what our coastal communities are dealing with.”

“Global sea-level rise is one of the greatest challenges facing society in the 21st century, and understanding how this phenomenon impacts coastal systems, infrastructure and the people who use them requires a regular coastal presence.”

Einstein turned this insight into an equation that described the jittering mathematically. His Brownian motion paper is widely recognized as the first incontrovertible proof that atoms and molecules really exist—and it still serves as the basis for some stock market forecasts.

He was trying to explain an odd fact that was first noticed by English botanist Robert Brown in 1827. Brown looked through his microscope and saw that the dust grains in a droplet of water were jittering around aimlessly. This Brownian motion, as it was first dubbed, had nothing to do with the grains being alive, so what kept them moving?

If you’ve been to a conference or played with a cat, chances are you’ve seen a laser pointer in action. In the nearly six decades since physicists demonstrated the first laboratory prototype of a laser in 1960, the devices have come to occupy almost every niche imaginable, from barcode readers to systems for hair removal.

So Einstein made an inspired guess: Maybe photons like to march in step, so that the presence of a bunch of them going in the same direction will increase the probability of a high-energy atom emitting another photon in that direction. He called this process stimulated emission, and when he included it in his equations, his calculations fit the observations perfectly

A laser is just a gadget for harnessing this phenomenon

"We eventually want to build a map of all of the planets orbiting the nearest stars to our own solar system, especially those that are potentially habitable," said Jeffrey Crane, study co-author and astronomer at the Carnegie Institution for Science.

Irrational stockpiling can also lead to price gouging, says Steven Taylor, a professor and clinical psychologist at the University of British Columbia, and the author of The Psychology of Pandemics. “If the price of a roll of toilet paper is tripled, that’s seen as a scarcer commodity to acquire, which can lead to anxiety,” he says.

Panic buying, Taylor says, is fuelled by anxiety, and a willingness to go to lengths to quell those fears: like queueing for hours or buying way more than you need. We’ve seen this before throughout history. Back in 1962 during the Cuban missile crisis, when nuclear war seemed imminent, American families filled their basements with enough canned goods and bottled water to survive an atomic blast.

“But for many people, hand-washing seems to be too ordinary. This is a dramatic event, therefore a dramatic response is required, so that leads to people throwing money at things in hopes of protecting themselves.”

“Panic is a subjective, emotional state, and mostly what we can observe is the behaviour,” says Oppenheim. “Maybe someone reads articles or a couple of tweets about supply chain disruptions in China and mask shortages in Hong Kong, and then makes a very reasoned decision to stock up on masks just in case. All we can infer from the purchasing is the timing, so it could look panicky even if it's well thought through.”

this distinction between mental and physical is not meaningful. Anxiety does not cause stomach aches; rather, feelings of anxiety and stomach aches are both ways that human brains make sense of physical discomfort

There is no such thing as a purely mental cause, because every mental experience has roots in the physical budgeting of your body. This is one reason physical actions like taking a deep breath, or getting more sleep, can be surprisingly helpful in addressing problems we traditionally view as psychological.

Your burden may feel lighter if you understand your discomfort as something physical. When an unpleasant thought pops into your head, like “I can’t take this craziness anymore,” ask yourself body-budgeting questions. “Did I get enough sleep last night? Am I dehydrated? Should I take a walk? Call a friend? Because I could use a deposit or two in my body budget.”

I’m not saying you can snap your fingers and dissolve deep misery, or sweep away depression with a change of perspective. I’m suggesting that it’s possible to acknowledge what your brain is actually doing and take some comfort from it

Your brain is not for thinking. Everything that it conjures, from thoughts to emotions to dreams, is in the service of body budgeting. This perspective, adopted judiciously, can be a source of resilience in challenging times.

Sleep is tied to many positive health outcomes according to a constant stream of medical research, much of which recommends more than seven hours a night. My goal was to sleep eight hours each night, and for the first two weeks of the month I tried and failed. I didn't manage it once. It started stressing me out.Wake up, people: You're fooling yourself about sleep, study says I did get more sleep than I would have otherwise because I prioritized getting to bed earlier. But between work, training for a marathon, kids' bedtimes and evening plans, my life was not conducive to that schedule. But since I'm making up the rules (and you make up yours) I gave up on sleep.

Research ties nature exposure to both longevity and happiness, so I made it a goal to commune with nature every day. This could include a run through a park, stopping to hug a tree (which I did at least once), or watching a convoy of ants cross a sidewalk.

Another super-habit for mental and physical health, I made an effort to incorporate meditation in some form -- whether it was 10 breaths, 30 minutes, guided, formal, mantra-led, what have you -- every day.

To complement March's switch-up, my plan for June was the same split: 8 hours of sleep at night and active listening with the kids. I didn't think I could pull a straight fortnight of great sleep, so my aim was for 15 nights of sleep and 15 days of not doing something else while listening.

At CNN, I sit near a constant pile of sweets. And that combined with my weakness for them equals a snacking problem. So in July, my goal was to make fresh fruit my standard snack of choice and eat at least one piece or serving a day. And more water -- at least a pint before coffee in the morning.

In August I attempted to not stay seated for more than 30 minutes during waking hours. Recent research has associated a number of poor health conditions with a sedentary lifestyle. And while no one can definitively say how much sitting is bad for us, moving every 30 minutes has emerged as a good guideline.

My commitment in September was 15 minutes of some form of creative writing each day, almost entirely in a writer's notebook that I've had since college. It's full of random dialogue, lists and story plots, and I used to write in it often but not so much in recent years.

Read a novel. That was it. Given that I mainly read non-fiction, this idea seemed rather novel (sorry).

My intention was to make a daily gesture of gratitude -- an emotional state with its own positive health outcomes -- and I quickly fell behind. I decided instead (because, again, I make up the rules) to make the goal a total of 30 thank yous, one for each day of the month, and I managed to cram them all in.

In another attempt to combat unhealthy snacking, my final goal for 2019 was to convert my diet into one filled with non-processed, whole foods. Carrots and peanut butter instead of donuts; almonds instead of old Halloween candy -- you get the idea. I also declared my intention to track my progress and give myself a daily score.

n the past, the pair has sparred in public over everything from the cause of California's wildfires to the state's stringent environmental regulations. Last year, Trump mocked the 52-year-old Newsom as the "do-nothing governor in California"; Newsom, for his part, has insisted his state will stand up to "a bully."

"We are clearly operating under a different set of assumptions," Newsom said when asked about Trump's desires during a recent briefing. He added that in their "many" conversations in recent weeks, it has been clear to him that the President understands the "unique challenges" faced by states like New York, California and Washington state.

As of 2 p.m. Wednesday, California had 3,006 cases of coronavirus and 65 dead. As the state has ramped up its testing capability the number of people who had been tested rose exponentially midweek, to 77,800, with results pending on more than 57,400 tests.

I don’t know if that sounds too complicated. But the point is, it’s not just giving up domination. It’s giving up this sense of separateness in favor of a sense of kinship. And those people who do often wonder how they failed to see how much continuity there is in the more-than-human world with the human world.

to go from terror into being and into that sense that the experiment is sacred, not this one outcome of the experiment, is to immediately transform the way that you think even about very fundamental social and economic and cultural things. If the experiment is sacred, how can we possibly justify our food systems, for instance?

when I first went to the Smokies and hiked up into the old growth in the Southern Appalachians, it was like somebody threw a switch. There was some odd filter that had just been removed, and the world sounded different and smelled different.

richard powersYeah. In human exceptionalism, we may be completely aware of evolutionary continuity. We may understand that we have a literal kinship with the rest of creation, that all life on Earth employs the same genetic code, that there is a very small core of core genes and core proteins that is shared across all the kingdoms and phyla of life. But conceptually, we still have this demented idea that somehow consciousness creates a sanctity and a separation that almost nullifies the continuous elements of evolution and biology that we’ve come to understand.

if we want to begin this process of rehabilitation and transformation of consciousness that we are going to need in order to become part of the living Earth, it is going to be other kinds of minds that give us that clarity and strength and diversity and alternative way of thinking that could free us from this stranglehold of thought that looks only to the maximizing return on investment in very leverageable ways.

richard powersIt amazed me to get to the end of the first draft of “Bewilderment” and to realize how much Buddhism was in the book, from the simplest things.

I think there is nothing more science inflected than being out in the living world and the more-than-human world and trying to understand what’s happening.

And of course, we can combine this with what we were talking about earlier with death. If we see all of evolution as somehow leading up to us, all of human, cultural evolution leading up to neoliberalism and here we are just busily trying to accumulate and make meaning for ourselves, death becomes the enemy.

And you’re making the point in different ways throughout the book that it is the minds we think of as unusual, that we would diagnose as having some kind of problem or dysfunction that are, in some cases, are the only ones responding to the moment in the most common sense way it deserves. It is almost everybody else’s brain that has been broken.

it isn’t surprising. If you think of the characteristics of this dominant culture that we’ve been talking about — the fixation on control, the fixation on mastery, the fixation on management and accumulation and the resistance of decay — it isn’t surprising that that culture is also threatened by difference and divergence. It seeks out old, stable hierarchies — clear hierarchies — of control, and anything that’s not quite exploitable or leverageable in the way that the normal is terrifying and threatening.

And the more I looked for it, the more it pervaded the book.

ezra kleinI’ve heard you say that it has changed the way you measure a good day. Can you tell me about that?richard powersThat’s true.I suppose when I was still enthralled to commodity-mediated individualist market-driven human exceptionalism — we need a single word for this

And since moving to the Smokies and since publishing “The Overstory,” my days have been entirely inverted. I wake up, I go to the window, and I look outside. Or I step out onto the deck — if I haven’t been sleeping on the deck, which I try to do as much as I can in the course of the year — and see what’s in the air, gauge the temperature and the humidity and the wind and see what season it is and ask myself, you know, what’s happening out there now at 1,700 feet or 4,000 feet or 5,000 feet.

let me talk specifically about the work of a scientist who has herself just recently published a book. It’s Dr. Suzanne Simard, and the book is “Finding the Mother Tree.” Simard has been instrumental in a revolution in our way of thinking about what’s happening underground at the root level in a forest.

it was a moving moment for me, as an easterner, to stand up there and to say, this is what an eastern forest looks like. This is what a healthy, fully-functioning forest looks like. And I’m 56 years old, and I’d never seen it.

the other topics of that culture tend to circle back around these sorts of trends, human fascinations, ways of magnifying our throw weight and our ability and removing the last constraints to our desires and, in particular, to eliminate the single greatest enemy of meaning in the culture of the technological sublime that is, itself, such a strong instance of the culture of human separatism and commodity-mediated individualist capitalism— that is to say, the removal of death.

Why is it that we have known about the crisis of species extinction for at least half a century and longer? And I mean the lay public, not just scientists. But why has this been general knowledge for a long time without public will demanding some kind of action or change

And when you make kinship beyond yourself, your sense of meaning gravitates outwards into that reciprocal relationship, into that interdependence. And you know, it’s a little bit like scales falling off your eyes. When you do turn that corner, all of the sources of anxiety that are so present and so deeply internalized become much more identifiable. And my own sense of hope and fear gets a much larger frame of reference to operate in.

I think, for most of my life, until I did kind of wake up to forests and to trees, I shared — without really understanding this as a kind of concession or a kind of subscription — I did share this cultural consensus that meaning is a private thing that we do for ourselves and by ourselves and that our kind of general sense of the discoveries of the 19th and 20th century have left us feeling a bit unsponsored and adrift beyond the accident of human existence.

The largest single influence on any human being’s mode of thought is other human beings. So if you are surrounded by lots of terrified but wishful-thinking people who want to believe that somehow the cavalry is going to come at the last minute and that we don’t really have to look inwards and change our belief in where meaning comes from, that we will somehow be able to get over the finish line with all our stuff and that we’ll avert this disaster, as we have other kinds of disasters in the past.

I think what was happening to me at that time, as I was turning outward and starting to take the non-human world seriously, is my sense of meaning was shifting from something that was entirely about me and authored by me outward into this more collaborative, reciprocal, interdependent, exterior place that involved not just me but all of these other ways of being that I could make kinship with.

And I think I was right along with that sense that somehow we are a thing apart. We can make purpose and make meaning completely arbitrarily. It consists mostly of trying to be more in yourself, of accumulating in one form or another.

I can’t really be out for more than two or three miles before my head just fills with associations and ideas and scenes and character sketches. And I usually have to rush back home to keep it all in my head long enough to get it down on paper.

for my journey, the way to characterize this transition is from being fascinated with technologies of mastery and control and what they’re doing to us as human beings, how they’re changing what the capacities and affordances of humanity are and how we narrate ourselves, to being fascinated with technologies and sciences of interdependence and cooperation, of those sciences that increase our sense of kinship and being one of many, many neighbors.

And that’s an almost impossible persuasion to rouse yourself from if you don’t have allies. And I think the one hopeful thing about the present is the number of people trying to challenge that consensual understanding and break away into a new way of looking at human standing is growing.

And when you do subscribe to a culture like that and you are confronted with the reality of your own mortality, as I was when I was living in Stanford, that sense of stockpiling personal meaning starts to feel a little bit pointless.

And I just head out. I head out based on what the day has to offer. And to have that come first has really changed not only how I write, but what I’ve been writing. And I think it really shows in “Bewilderment.” It’s a totally different kind of book from my previous 12.

the marvelous thing about the work, which continues to get more sophisticated and continues to turn up newer and newer astonishments, is that there was odd kind of reciprocal interdependence and cooperation across the species barrier, that Douglas firs and birches were actually involved in these sharing back and forth of essential nutrients. And that’s a whole new way of looking at forest.

she began to see that the forests were actually wired up in very complex and identifiable ways and that there was an enormous system of resource sharing going on underground, that trees were sharing not only sugars and the hydrocarbons necessary for survival, but also secondary metabolites. And these were being passed back and forth, both symbiotically between the trees and the fungi, but also across the network to other trees so that there were actually trees in wired up, fungally-connected forests where large, dominant, healthy trees were subsidizing, as it were, trees that were injured or not in favorable positions or damaged in some way or just failing to thrive.

so when I was still pretty much a card-carrying member of that culture, I had this sense that to become a better person and to get ahead and to really make more of myself, I had to be as productive as possible. And that meant waking up every morning and getting 1,000 words that I was proud of. And it’s interesting that I would even settle on a quantitative target. That’s very typical for that kind of mindset that I’m talking about — 1,000 words and then you’re free, and then you can do what you want with the day.

there will be a threshold, as there have been for these other great social transformations that we’ve witnessed in the last couple of decades where somehow it goes from an outsider position to absolutely mainstream and common sense.

I am persuaded by those scholars who have showed the degree to which the concept of nature is itself an artificial construction that’s born of cultures of human separatism. I believe that everything that life does is part of the living enterprise, and that includes the construction of cities. And there is no question at all the warning that you just gave about nostalgia creating a false binary between the built world and the true natural world is itself a form of cultural isolation.

Religion is a technology to discipline, to discipline certain parts of the human impulse. A lot of the book revolves around the decoded neurofeedback machine, which is a very real literalization of a technology, of changing the way we think

one of the things I think that we have to take seriously is that we have created technologies to supercharge some parts of our natural impulse, the capitalism I think should be understood as a technology to supercharge the growth impulse, and it creates some wonders out of that and some horrors out of that.

richard powersSure. I base my machine on existing technology. Decoded neurofeedback is a kind of nascent field of exploration. You can read about it; it’s been publishing results for a decade. I first came across it in 2013. It involves using fMRI to record the brain activity of a human being who is learning a process, interacting with an object or engaged in a certain emotional state. That neural activity is recorded and stored as a data structure. A second subsequent human being is then also scanned in real time and fed kinds of feedback based on their own internal neural activity as determined by a kind of software analysis of their fMRI data structures.

And they are queued little by little to approximate, to learn how to approximate, the recorded states of the original subject. When I first read about this, I did get a little bit of a revelation. I did feel my skin pucker and think, if pushed far enough, this would be something like a telepathy conduit. It would be a first big step in answering that age-old question of what does it feel like to be something other than we are

in the book I simply take that basic concept and extend it, juke it up a little bit, blur the line between what the reader might think is possible right now and what they might wonder about, and maybe even introduce possibilities for this empathetic transference

ezra kleinOne thing I loved about the role this played in the book is that it’s highlighting its inverse. So a reader might look at this and say, wow, wouldn’t that be cool if we had a machine that could in real time change how we think and change our neural pathways and change our mental state in a particular direction? But of course, all of society is that machine,

Robin and Theo are in an airport. And you’ve got TVs everywhere playing the news which is to say playing a constant loop of outrage, and disaster, and calamity. And Robbie, who’s going through these neural feedback sessions during this period, turns to his dad and says, “Dad, you know how the training’s rewiring my brain? This is what is rewiring everybody else.”

ezra kleinI think Marshall McLuhan knew it all. I really do. Not exactly what it would look like, but his view and Postman’s view that we are creating a digital global nervous system is a way they put it, it was exactly right. A nervous system, it was such the exact right metaphor.

the great insight of McLuhan, to me, what now gets called the medium is the message is this idea that the way media acts upon us is not in the content it delivers. The point of Twitter is not the link that you click or even the tweet that you read; it is that the nature and structure of the Twitter system itself begins to act on your system, and you become more like it.If you watch a lot of TV, you become more like TV. If you watch a lot of Twitter, you become more like Twitter, Facebook more like Facebook. Your identities become more important to you — that the content is distraction from the medium, and the medium changes you

it is happening to all of us in ways that at least we are not engaging in intentionally, not at that level of how do we want to be transformed.

richard powersI believe that the digital neural system is now so comprehensive that the idea that you could escape it somewhere, certainly not in the Smokies, even more remotely, I think, becomes more and more laughable. Yeah, and to build on this idea of the medium being the message, not the way in which we become more like the forms and affordances of the medium is that we begin to expect that those affordances, the method in which those media are used, the physiological dependencies and castes of behavior and thought that are required to operate them and interact with them are actual — that they’re real somehow, and that we just take them into human nature and say no, this is what we’ve always wanted and we’ve simply been able to become more like our true selves.

Well, the warpage in our sense of time, the warpage in our sense of place, are profound. The ways in which digital feedback and the affordances of social media and all the rest have changed our expectations with regard to what we need to concentrate on, what we need to learn for ourselves, are changing profoundly.

If you look far enough back, you can find Socrates expressing great anxiety and suspicion about the ways in which writing is going to transform the human brain and human expectation. He was worried that somehow it was going to ruin our memories. Well, it did up to a point — nothing like the way the digital technologies have ruined our memories.

my tradition is Jewish, the Sabbath is a technology, is a technology to create a different relationship between the human being, and time, and growth, and productive society than you would have without the Sabbath which is framed in terms of godliness but is also a way of creating separation from the other impulses of the weak.

Governments are a technology, monogamy is a technology, a religiously driven technology, but now one that is culturally driven. And these things do good and they do bad. I’m not making an argument for any one of them in particular. But the idea that we would need to invent something wholly new to come up with a way to change the way human beings act is ridiculous

My view of the story of this era is that capitalism was one of many forces, and it has become, in many societies, functionally the only one that it was in relationship with religion, it was in relationship with more rooted communities.

it has become not just an economic system but a belief system, and it’s a little bit untrammeled. I’m not an anti-capitalist person, but I believe it needs countervailing forces. And my basic view is that it doesn’t have them anymore.

the book does introduce this kind of fable, this kind of thought experiment about the way the affordances that a new and slightly stronger technology of empathy might deflect. First of all, the story of a little boy and then the story of his father who’s scrambling to be a responsible single parent. And then, beyond that, the community of people who hear about this boy and become fascinated with him as a narrative, which again ripples outward through these digital technologies in ways that can’t be controlled or whose consequences can be foreseen.

I’ve talked about it before is something I’ve said is that I think a push against, functionally, materialism and want is an important weight in our society that we need. And when people say it is the way we’ll deal with climate change in the three to five year time frame, I become much more skeptical because to the point of things like the technology you have in the book with neural feedback, I do think one of the questions you have to ask is, socially and culturally, how do you move people’s minds so you can then move their politics?

You’re going to need something, it seems to me, outside of politics, that changes humans’ sense of themselves more fundamentally. And that takes a minute at the scale of billions.

richard powersWell, you are correct. And I don’t think it’s giving away any great reveal in the book to say that a reader who gets far enough into the story probably has this moment of recursive awareness where they, he or she comes to understand that what Robin is doing in this gradual training on the cast of mind of some other person is precisely what they’re doing in the act of reading the novel “Bewilderment” — by living this act of active empathy for these two characters, they are undergoing their own kind of neurofeedback.

The more we understand about the complexities of living systems, of organisms and the evolution of organisms, the more capable it is to feel a kind of spiritual awe. And that certainly makes it easier to have reverence for the experiment beyond me and beyond my species. I don’t think those are incommensurable or incompatible ways of knowing the world. In fact, I think to invoke one last time that Buddhist precept of interbeing, I think there is a kind of interbeing between the desire, the true selfless desire to understand the world out there through presence, care, measurement, attention, reproduction of experiment and the desire to have a spiritual affinity and shared fate with the world out there. They’re really the same project.

richard powersWell, sure. If we turn back to the new forestry again and researchers like Suzanne Simard who were showing the literal interconnectivity across species boundaries and the cooperation of resource sharing between different species in a forest, that is rigorous science, rigorous reproducible science. And it does participate in that central principle of practice, or collection of practices, which always requires the renunciation of personal wish and ego and prior belief in favor of empirical reproduction.

I’ve begun to see people beginning to build out of the humbling sciences a worldview that seems quite spiritual. And as you’re somebody who seems to me to have done that and it has changed your life, would you reflect on that a bit?

So much of the book is about the possibility of life beyond Earth. Tell me a bit about the role that’s playing. Why did you make the possibility of alien life in the way it might look and feel and evolve and act so central in a book about protecting and cherishing life here?

richard powersI’m glad that we’re slipping this in at the end because yes this framing of the book around this question of are we alone or does the universe want life it’s really important. Theo, Robin’s father, is an astrobiologist.

Imagine that everything happens just right so that every square inch of this place is colonized by new forms of experiments, new kinds of life. And the father trying to entertain his son with the story of this remarkable place in the sun just stopping him and saying, Dad, come on, that’s asking too much. Get real, that’s science fiction. That’s the vision that I had when I finished the book, an absolutely limitless sense of just how lucky we’ve had it here.

one thing I kept thinking about that didn’t make it into the final book but exists as a kind of parallel story in my own head is the father and son on some very distant planet in some very distant star, many light years from here, playing that same game. And the father saying, OK, now imagine a world that’s just the right size, and it has plate tectonics, and it has water, and it has a nearby moon to stabilize its rotation, and it has incredible security and safety from asteroids because of other large planets in the solar system.

they make this journey across the universe through all kinds of incubators, all kinds of petri dishes for life and the possibilities of life. And rather than answer the question — so where is everybody? — it keeps deferring the question, it keeps making that question more subtle and stranger

For the purposes of the book, Robin, who desperately believes in the sanctity of life beyond himself, begs his father for these nighttime, bedtime stories, and Theo gives him easy travel to other planets. Father and son going to a new planet based on the kinds of planets that Theo’s science is turning up and asking this question, what would life look like if it was able to get started here?

a new book, The Experience Machine: How Our Minds Predict and Shape Reality, which is remarkable for how it connects the high-level concepts to everyday examples of how our brains make predictions, how that process can lead us astray, and what we can do about it.

being driven to stay within your own viability envelope is crucial to the kind of intelligence that we know about—the kind of intelligence that we are

If you ask what is a predictive brain for, the answer has to be: staying alive. Predictive brains are a way of staying within your viability envelope as an embodied biological organism: getting food when you need it, getting water when you need it.

in predictive processing, perception is structured around prediction. Perception is about the brain having a guess at what’s most likely to be out there and then using sensory information to refine the guess.

artificial curiosity. Predictive-processing systems automatically have that. They’re set up so that they predict the conditions of their own survival, and they’re always trying to get rid of prediction errors. But if they’ve solved all their practical problems and they’ve got nothing else to do, then they’ll just explore. Getting rid of any error is going to be a good thing for them. If you’re a creature like that, you’re going to be a really good learning system. You’re going to love to inhabit the environments that you can learn most from, where the problems are not too simple, not too hard, but just right.

It’s an effect that you also see in Marieke Jepma et al.’s work on pain. They showed that if you predict intense pain, the signal that you get will be interpreted as more painful than it would otherwise be, and vice versa. Then they asked why you don’t correct your misimpression. If it’s my expectation that is making it feel more painful, why don’t I get prediction errors that correct it?

The reason is that there are no errors. You’re expecting a certain level of pain, and your prediction helps bring that level about; there is nothing for you to correct. In fact, you’ve got confirmation of your own prediction. So it can be a vicious circle

Do you think this self-fulfilling loop in psychosis and pain perception helps to account for misinformation in our society’s and people’s susceptibility to certain narratives?Absolutely. We all have these vulnerabilities and self-fulfilling cycles. We look at the places that tend to support the models that we already have, because that’s often how we judge whether the information is good or not

Given that we know we’re vulnerable to self-fulfilling information loops, how can we make sure we don’t get locked into a belief?Unfortunately, it’s really difficult. The most potent intervention is to remind ourselves that we sample the world in ways that are guided by the models that we’ve currently got. The structures of science are there to push back against our natural tendency to cherry-pick.
