Yes, billions of dinosaur bodies died and fell to the Earth here in this span, and trillions more dinosaur footsteps pressed into the Earth, but hardly a trace remains today. A cryptic smattering of lakeside footprints represents their entire contribution to the Triassic period. A few bones and footsteps miraculously preserved in New England and Nova Scotia are all that remains from the entire 27-million-year Early Jurassic epoch. No trace of dinosaurs remains whatsoever from the 18-million-year Late Jurassic. A handful of bones from one layer in Maryland represents the entire 45-million-year Early Cretaceous; the Late Cretaceous gives up a Hadrosaurus in New Jersey, and part of a tyrannosaur in Alabama, but mostly comprises unimpressive fragments of bone and teeth that cover the remaining 34 million years of the Earth’s most storied age, until doomsday

So that’s what 180 million years of complete dominance buys you in the fossil record. What, then, will a few decades of industrial civilization get us? This is the central question of the Anthropocene—an epoch that supposedly started, not tens of millions of years ago, but perhaps during the Truman administration

as the example of the dinosaurs shows, the chance that any city-swallowing delta deposit from a window of time only a few centuries wide would be lucky enough to be not only buried and preserved for safekeeping, but then subsequently not destroyed—in the ravenous maw of a subduction zone, or sinking too close to the cleansing metamorphic forge of Earth’s mantle, or mutilated in some m

there exists a better word in geology than epoch to describe our moment in the sun thus far: event. Indeed, there have been many similarly disruptive, rapid, and unusual episodes scattered throughout Earth history—wild climate fluctuations, dramatic sea-level rises and falls, global ocean-chemistry disasters, and biodiversity catastrophes

nd then, after all that, find itself, at a given point in the far future, fantastically lucky enough to have been serendipitously pushed up just enough so as to be exposed at the surface, but not too high as to have been quickly destroyed by erosion … is virtually ni

What else of us could be sampled from this sliver of deep-sea-muck-turned-rock—these Anthropocene clays and shale layers? Pass it through a mass spectrometer and you would see, encoded in its elements, the story of the entire planet in this strange interval, the Great Derangement of the Earth’s systems by civilization. You would see our lightning-fast injection of hundreds of gigatons of light carbon into the atmosphere written in the strange skew of carbon isotopes in this rock—as you do in rocks from the many previous carbon-cycle disasters of Earth history. The massive global-warming pulse created by this carbon disaster would be written in oxygen isotope

The sulfur, nitrogen, thallium, and uranium isotopes in these rocks (to mention just a few) would whisper to you—again, in squiggles on a graph—that the global ocean lost much of its oxygen during this brief but enigmatic interval. Strontium isotopes would tell you that rock weathering dramatically accelerated worldwide for a few tens of thousands of years as sweltering, violent storms attacked the rocks and wore down the continents during a brief, CO2-driven fever.

The most enduring geological legacy, instead, will be the extinctions we cause. The first wave of human-driven extinctions, and the largest hit to terrestrial megafauna since the extinction of the dinosaurs, began tens of thousands of years ago, as people began to spread out into new continents and islands, wiping out everything we tend to think of as “Ice Age” faun

we’re very likely to return to our regularly scheduled programming and dive back into a punishing Ice Age in the next half-million years. This means that sea level—after shooting up in the coming millennia by our own hand, and potentially burying coastal settlements in sediment (good for fossilization)—will eventually fall hundreds of feet below where it is today, and subject the shallow continental shelves, along with our once submerged cities and magnificent seams of garbage, to the cold winds of erosion (bad for fossilization), where they’ll be mostly reduced to nothing

The first major mass extinction, 445 million years ago, took place in multiple pulses across a million years. An event. The second major mass extinction, 70 million years later, took place over 600,000 years—400,000 years longer than the evolutionary history of Homo sapiens.

The idea of the Anthropocene inflates our own importance by promising eternal geological life to our creations. It is of a thread with our species’ peculiar, self-styled exceptionalism—from the animal kingdom, from nature, from the systems that govern it, and from time itself. This illusion may, in the long run, get us all killed.

There is one case 65 million years ago, at a point in time known as the Cretaceous-Tertiary boundary (K-T boundary), with strong evidence supporting an asteroid impact around the same time the dinosaurs disappeared.

“That one instance really guided everybody’s thinking, and the idea that impacts caused mass extinctions was really, really popular,” said Renne, who wasn’t involved in the Blackburn study.

enne says that even the asteroid impact at the K-T boundary likely only finished the job that major volcanic eruptions in India started. (Related: “What Killed Dinosaurs: New Ideas About the Wipeout.”)

But the situation changed for animals larger than about 2,000 pounds — those dinosaurs moved considerably slower, according to the equations that included their mass compared with those that just included stride length and hip height.

That schism left Dr. Dececchi and his colleagues wondering about the evolutionary advantage of lanky limbs for a massive dinosaur.

“It may have been one of the traits that allowed them to become so successful.”

. A March Gallup poll found that Republicans were much less likely than Democrats or independents to say that they worried about global warming. Only 16 percent of Republicans said that they worried a great deal about it, while 42 percent of Democrats and 31 percent of independents did.

This volcanism-induced warming, far-removed from the extinction, casts blame squarely on the Chicxulub event. “I’m sure the debate will rage on, because there are entrenched voices on either side,” Dr. Brusatte said. “But it’s getting harder and harder to fathom that the asteroid was innocent.”

In the past, when I’ve made the ‘where do you draw the line?’ argument to woke teachers, they dismiss the notion that any child might identify as an animal as a ‘red herring’. But it turns out, if you encourage kids to part company with biological reality, there’s nothing to stop them believing they’re cats or dinosaurs – or, indeed, red herring

Will doctors nod along enthusiastically when a teenage girl insists she’s a grub and then pack her off to surgery to have her arms and legs removed? Will a Labour government pass an act of parliament enabling ‘furries’ to marry cats and dogs?

Within another two million to three million years, Dr. O’Leary said, the first members of modern placental orders appeared in such profusion that researchers have started to refer to the explosive model of mammalian evolution

Although some small primitive mammals had lived in the shadow of the great Cretaceous reptiles, the scientists could not find evidence supporting an earlier hypothesis that up to 39 placental mammalian lineages survived to enter the post-extinction world. Only the stem lineage to Placentalia, they said, appeared to hang on through the catastrophe, generally associated with climate change after an asteroid crashed into Earth.

the “power of 4,500 characters” enabled the scientists to look “at all aspects of mammalian anatomy, from the skull and skeleton, to the teeth, to internal organs, to muscles and even fur patterns” to determine what the common ancestor possibly looked like.

this formidable new systematic data-crunching capability might reshape mammal research but that it would probably not immediately resolve the years of dispute between fossil and genetic partisans over when placental mammals arose. Paleontologists looking for answers in skeletons and anatomy have favored a date just before or a little after the Cretaceous extinction. Those who work with genetic data to tell time by “molecular clocks” have arrived at much earlier origins.

the post-Cretaceous date for the placentals “will surely be controversial, as this is much younger than estimates based on molecular clocks, and implies the compression of very long molecular branches at the base of the tree.”

The United States is one of the rich countries that bucks the trend. About two-thirds of Americans — 65 percent — say religion is important in their daily lives. Among high-income countries, only Italians, Greeks, Singaporeans and residents of the oil-rich Persian Gulf states are more likely to say religion is important.

nearly a third of Americans continue to believe that the Bible “is the actual word of God and is to be taken literally, word for word.”

some Americans seem to live in a world where facts can’t exist.Facts such as the idea that the world is ancient, and that all living things evolved and some — like dinosaurs — became extinct. Facts like the proven warming of the world. Facts like the very real possibility that such warming could cause a catastrophic sea-level rise.

There’s little predictability in how things will play out after this anthropogenic jolt, especially in the living world. [More on the “great acceleration” behind the jolt is here.]

That’s a very different sensation than, say, mourning the end of nature. It’s more a celebration, in a way — a deeper acceptance of our place on the planet, with all of our synthetic trappings, and our faults, as fundamentally natural.

on whether it’s possible to have a “good Anthropocene.” Kolbert’s Twitter post last spring nicely captured their view:

Taking full ownership of the Anthropocene won’t be easy. The necessary feeling is a queasy mix of excitement and unease. I’ve compared it to waking up in the first car on the first run of a new roller coaster that hasn’t been examined fully by engineers.

Once you begin to get the many feedbacks bouncing off each other and bouncing off the Earth system, it’s going to be very hard to follow what’s going to happen, particularly biologically…. One could not imagine, at the very end of the Cretaceous, the beginning of the Tertiary, that the mammals — these itty-bitty little squeaky furry things, would take over – effectively taking the position that the dinosaurs held for so long. All we can say is that, for sure, it will be different. We’re going down a different trouser leg of history.

in the broadest sense we have to embrace the characteristics, good and bad, that make humans such a rare thing — a species that has become a planet-scale force.

“The way I would like to see it is in, say, 100 years in the future the London Geological Society will look back and consider this period…a transition from the lesser Anthropocene to the greater Anthropocene.”

Fully integrating this awareness into our personal choices and societal norms and policies will take time. It is “the great work,” as Thomas Berry put it.

Technology alone will not do the trick. Another keystone to better meshing humanity’s infinite aspirations with life on a finite planet will be slowly shifting value systems from the foundation up

Edward O. Wilson’s “Biophilia” was a powerful look outward at the characteristics of the natural world that we inherently cherish.

Now we need a dose of what I’ve taken to calling anthropophilia, as well.

We have to accept ourselves, flaws and all, in order to move beyond what has been something of an unconscious, species-scale pubescent growth spurt, enabled by fossil fuels in place of testosterone.

We’re stuck with “The World With Us.” It’s time to grasp that uncomfortable, but ultimately hopeful, idea.

But no serious scientist claims “total certainty” about the future of climate, just a range of increasingly alarming probabilities; no one is demanding “abrupt and expensive” changes in public policy, just an intensification of efforts long underway with increasingly reliable and affordable new technologies; and, yes, treating your opponents as evil morons is rarely a good political strategy

The same blather can be found in this week’s column by Jonah Goldberg, lamenting Max Boot’s sudden volte-face on the issue. Jonah has a point about Boot’s somewhat too instant makeover into a resistance icon (I’ve made it myself), but on the substance of climate change, what defense of the American right does Goldberg have? Zippo. He argues that “there are a lot of different views on climate change on the right.” I find that about as convincing as the argument that there are a lot of different views on race among Harvard’s faculty.

More to the point, the hypothesis of carbon-created climate change doesn’t just have “some legitimate science” on its side, as Goldberg puts it, but a completely overwhelming majority of the science

You should, of course, retain some skepticism always. It’s possible, for example, that natural selection may be replaced as the core scientific consensus about how life on Earth evolved. Possible. But do we have to express skepticism every time new science based on that hypothesis emerges

I honestly can’t see how the science of this can be right or left. It’s either our best working hypothesis or not.

Inaction because of uncertainty only makes sense if the threat is distant and not too calamitous. But when there’s a chance of it being truly catastrophic, and the evidence in its favor keeps strengthening, a sane person adjusts

A conservative person — someone attuned to risk — will take out insurance, in case the worst happens.

Why is every other government on Earth committed to tackling this (rhetorically at least) and every other center-right party on Earth taking this very seriously? (Check out this page about environmental policy in the British Conservative party — aimed getting to zero carbon emissions by 2050 — and see if you even recognize the debate on the right in the U.S.)

The kicker, of course, is that the current GOP is not just skeptical of climate science and dragging its feet on doing anything about climate change. It is actively pursuing policies aimed at intensifying environmental devastation. Trump’s EPA is attempting to gut the regulation of carbon; it has tried to sabotage the only most prominent global agreement on the matter; it celebrates carbon-based energy and rhapsodizes about coal; it has slapped a 30 percent tariff on solar panels; its tax reform hurt solar and wind investment

For allegedly intelligent conservatives like Stephens and Goldberg to devote energy toward climate skepticism while turning a blind eye to vigorous Republican climate vandalism is, quite simply contemptible. I am not reading their minds here. I’m reading their columns. On this question — as on fiscal policy — they’re not skeptics or conservatives; they are dogmatists, sophists, and enablers of environmental vandalism. They reveal Republicanism’s calculated assault on the next generations — piling them with unimaginable debt and environmental chaos. This isn’t the cultural conservatism of Burke; it’s the selfish nihilism of Rand.

a quote. It was the first time a major global leader spoke to the U.N. on the question: “It is life itself — human life, the innumerable species of our planet — that we wantonly destroy. It is life itself that we must battle to preserve … The danger of global warming is as yet unseen but real enough for us to make changes and sacrifices so we may not live at the expense of future generations. That prospect is a new factor in human affairs. It is comparable in its implications to the discovery of how to split the atom, indeed its results could be even more far-reaching … We should always remember that free markets are a means to an end. They would defeat their object if by their output they did more damage to the quality of life through pollution than the well-being they achieve by the production of goods and services.”

That leader also made a core moral argument: “No generation has a freehold on this Earth; all we have is a life tenancy with a full repairing lease.

Those words were Margaret Thatcher’s in 1989. She devoted her entire U.N. speech to conservation and climate change. If the subject was real enough in 1989 to make sacrifices and changes, how much more so almost 30 years later?

The difference between Thatcher and today’s Republicans is quite a simple one. She believed in science (indeed was trained as a scientist). She grasped the moral dimensions of the stewardship of the Earth from one generation to another. She did not engage in the cowardice of sophists. And unlike these tools and fools on today’s American right, she was a conservative.

The real question, it seems to me, is therefore an almost philosophical one: Do these exceptions prove or disprove a general rule?

I’d argue that, by and large, they prove it

The number of people with a mismatch between chromosomes and hormones, or with ambiguous genitalia, is surpassingly small. Well under one percent is a useful estimate.

Similarly with a transgender identity: It absolutely exists but is also very rare — some estimates put it at around 0.7 percent of the population

Gay men and lesbians who have unambiguous male and female sex organs and identity but an attraction to their own sex are also pretty rare (whatever we’d like to think). Maybe 2 to 5 percent, with some outliers

Does this mean that general assumptions about most people being either male or female and heterosexual and cisgendered are misplaced or even offensive? Hardly. I’m gay but usually assume that everyone I meet is straight until I know otherwise

And I don’t mind the hetero assumption applying to me either. It’s a reasonable statistical inference, not bigotry. And I can always set them, er, straight.

My preferred adjective for sex and gender is bimodal, rather than binary. What bimodal means is that there are two distinct and primary modes with some variations between them

Think of it as two big mountains representing, in sex matters, well over 95 percent of humans, with a long, low valley between them, representing the remaining percent.

Everyone is equally human. But clearly the human experience of sex is one thing for almost everyone and a different thing for a few.

Do we infer from this that we need to junk the categories of male and female altogether, as many critical gender theorists argue? That seems insane to me

These two modes actually define the entire landscape of sex (the exceptions are incomprehensible without them), and the bimodal distribution is quite obviously a function of reproductive strategy (if we were all gay, or intersex, we’d cease to exist as a species before too long)

Ditto the transgender experience: Does the fact that less than one percent of humans feel psychologically at odds with their biological sex mean that biological sex really doesn’t exist and needs to be defined away entirely? Or does it underline just how deep the connection between sex and gender almost always is?

We are not a threat to straights; we’re a complement. Transgender people do not threaten the categories of male and female; they pay, in some ways, homage to them.

On the left, there’s too much defensiveness about being in a minority

But being in a minority — even a tiny one — need not be demoralizing, if we have self-confidence. I’d argue it can lead, through struggle and challenge, to a more deeply examined self — and to a resilience that can only be earned and is no one else’s to give.

You will, in fact, end up with … an individual human being!

It’s stupid to pretend they are entirely normal, because it gives the concept of normality too much power over us. Their abnormality is a neutral thing, like left-handedness: a fact, not a judgment. And why on earth should we feel defensive about that?

But what surprised me was the positive response to a single, minor point I made about intersectionality.

In some ways, I argued, the intersectional move on the hard left is a good thing — because it complicates things. It’s no longer enough just to consider race, for example, as a signifier of oppression without also considering gender or orientation or gender identity, national origin, immigrant status, etc. When society is made up entirely of various intersecting oppressions, as the social-justice left believes, it’s vital not to leave any potential grievance out.

By the same token, of course, an oppressor can also be identified in multiple, intersectional ways

It can get very complicated very fast.

Let’s push this to its logical conclusion. Let’s pile on identity after identity for any individual person; place her in multiple, overlapping oppression dynamics, victim and victimizer, oppressor and oppressed; map her class, race, region, religion, marital status, politics, nationality, language, disability, attractiveness, body weight, and any other form of identity you can

After a while, with any individual’s multifaceted past, present, and future, you will end up in this multicultural world with countless unique combinations of endless identities in a near-infinite loop of victim and victimizer.

And the fact that this society is run overwhelmingly on heterosexual lines makes sense to me, given their overwhelming majority. As long as the government does not actively persecute or enable the persecution of a minority, who cares

In the end, all totalizing ideologies disappear up their own assholes. With intersectionality, we have now entered the lower colon

It’s been healthy for me, a fair-haired Anglo-Saxon with a Roman numeral in my name (John Austin Murphy III), to be a minority in my workplace, and in some of the neighborhoods where I deliver

During my 33 years at Sports Illustrated, I wrote six books, interviewed five U.S. presidents, and composed thousands of articles for SI and SI.com. Roughly 140 of those stories were for the cover of the magazine, with which I parted ways in May of 2017. Since then, as Jeff Lebowski explains to Maude between hits on a postcoital roach, “my career has slowed down a little bit.

There’s also a bracing feeling of independence that attends piloting my own van, a tingle of anticipation before finding out my route for the day

it’s been illuminating to see exactly how a package makes the final leg of its journey.

Performing my new job, I’m frequently reminded of my old one, whether it’s driving past Memorial Stadium in Berkeley, where I covered countless Pac-12 games, or listening to NFL contests during Sunday deliveries. I’ve talked and laughed with many of the players and coaches and general managers and owners whose names I hear.

Lurching west in stop-and-go traffic on I-80 that morning, bound for Berkeley and a day of delivering in the rain, I had a low moment, dwelling on how far I’d come down in the world. Then I snapped out of it. I haven’t come down in the world. What’s come down in the world is the business model that sustained Time Inc. for decades. I’m pretty much the same writer, the same guy. I haven’t gone anywhere.

It’s worth noting that the original version of the Green New Deal was devised by the left-leaning British National Economic Foundation, as a means for recovery after the 2008 economic collapse

Once Labour’s full, staggeringly bold proposals were unveiled, support for the party soared

Labour climbed a full 20 points in the six weeks of the 2017 campaign, robbing the Tories of a majority in the Parliament

So it seems to me there is a massive opportunity for the left now across the Western world. Look at how popular a 70 percent top rate is … in America! The left is correct to sense a huge opportunity and they are right, I think, to be bold.

I wrote about Jeremy Corbyn’s Labour last year in these pages, and that, under his leadership, “it turned out to be difficult to propel a new movement of left radicalism without simultaneously tapping into a vein of left extremism,” and that seems to me to be precisely the challenge in the U.S. as well

the full package from the contemporary radicalized left in both the U.K. and U.S. brings with it far more troubling ideas

If they insist on calling our multicultural and multiracial democracy a manifestation of “white supremacy,” they will empower real white supremacists.

A passion for social justice curdles into attacks on free speech

Postmodern critical gender theory denies any meaningful natural differences between men and women, and casts an entire sex as inherently problematic

Concern about mass immigration is dismissed as nothing but racism and xenophobia.

so Labour, after so much promise and success, has not been able to get any sustainable polling lead over the most shambolic Tory government in memory.

If the Democrats want to fight the next election on the need for a radical rebalancing of the economy in favor of the middle and working class, for massive investment in new green technology, for higher taxes on the superrich, and for health-care security for all Americans, they can win

If they conflate those goals with extremist rhetoric about abolishing everyone’s current health insurance, and starting from scratch, as the Green New Deal advises, not so much

If they insist that men and women are indistinguishable, that girls can have penises and boys can have periods, as transgender ideology now demands, they’ll seem nuts to most fair-minded people.

Hostility to the policies of the state of Israel — a perfectly legitimate position — morphs swiftly into ugly anti-Semitic tropes

It’s not easy to find any heroes in Washington these days, so allow me to eulogize one. Walter Jones was a longtime Republican congressman from North Carolina, who died earlier this wee

Are they really capable of fucking this up once again? The answer that is emerging in the first months of the new Democratic House is: of course they can.

we may be underestimating what the constant drumbeat of news about the accelerating sixth great extinction has been doing to us psychologically.

I’m haunted all the time by the knowledge of what my lifetime will have witnessed. Humans are committing countless species to death; we are destroying the life of our oceans and skies; we are changing the planet’s ecosystem more quickly than at any time since the asteroids wiped out the dinosaurs. From the perspective of life itself, we are conducting a holocaust of the natural world. How is the knowledge of this not traumatizing?

A new report from the Institute for Public Policy Research notes, according to the BBC, that “since 1950, the number of floods across the world has increased by 15 times, extreme temperature events by 20 times, and wildfires seven-fold.”

Last week, research emerged showing that the insect biomass is declining by 2.5 percent a year, which means that we may wipe out the entire insect population within a century — and lose a quarter of it in the next ten years.

This amounts to what Jill Kieldash describes as the “actual structural and functional collapse of the natural systems which have supported life on Earth for the last 400 million years.”

I don’t know how this paradigm affects you every day, but it is for me the gutting context for everything, a growing nausea laced with guilt and shame.

In a century, we will have destroyed this Earth as we have known it — in absolutely full awareness of what we are doing. It’s the greatest crime humanity has ever committed

One answer could be that they are behaving in a classic way when a catastrophe strikes: They’re traumatized by this knowledge, and they cope with this trauma by a classic form of disassociation. In fact, we are all living through this collective trauma

Once we become aware of its true scope, depth, and accelerating pace, we then begin to view everything else through the traumatic lens of the climate crisis

How could anyone with a reasonably realistic, educated worldview not be haunted by the perpetual specter of Climate Trauma when considering fundamental life and identity choices?

I am not surprised by declining birth rates in the West. Having a child in today’s era means initiating another human being into the end of the world as we have known it

I find my own witnessing of the collapse of liberal democratic values in the West inseparable from the mass extinction of life on Earth our civilization has wrought — and the double depression this creates makes me want to escape

this collective trauma is never-ending. It’s a 9/11 all the time. Woodbury notes the similarity between our knowledge of future planetary collapse and a diagnosis of a terminal disease: “You may put it out of your mind for spells, but the grief associated with prospective loss comes at you in waves.

The challenge is to resist disassociation — which is “the human capacity to mentally escape an insufferable reality.

We are disassociating from America in our current dystopian politics. But we are also, more profoundly, disassociating ourselves from our deepest ecological reality: that we are killing what created us. And we cannot seem to stop.

If they call a border wall an “immorality” and refuse to fund a way to detain and humanely house the huge surge of migrant families and children now overwhelming the southern border (up 290 percent over the same period in 2018, with a record 1,800 apprehensions on Monday of this week alone!), they will rightly be called in favor of open borders

when it became clear that the Iraq War had been based on phony intelligence, he actually changed his mind. More than that: He took moral responsibility for his vote for the war, and rethought a great deal of his previous views. Ashamed of what he had done — and the lives lost because of the war — he went on to write 12,000 letters to family members of service members killed

he tirelessly fought to bring back war-making powers to the Senate, where they belong. He took on his own party leadership in demanding votes before military adventures

He was that very rare creature: a true Republican fiscal conservative

Of course a man of this character was a dogged defender of his own constituents, especially those in the military subjected to unfairness or injustice of any kin

This didn’t make him a liberal. It made him a conservative. And he proved that to be a conservative these days — a humane, decent, honest, principled conservative — you really have no place in the Republican Party

And then there’s another question. Even if we can survive, is that the world you want to live in? Is that the world you want all future generations of humans to live in? That’s a different question. But they’re both extremely serious. I would say they really couldn’t be more serious.

Biodiversity is defined as the variety of living organisms,

In another stark example of the dangers to marine life from human actions, one turtle followed was found dead on a beach in Suriname only 120km (74 miles) from the starting point, drowned after having become enmeshed in a discarded fishing net.

Estimates say more than half of all sea turtles have ingested plastic. The animals also face threats from overfishing, though they are mainly bycatch rather than targets.

“Sea turtles survived the extinction of the dinosaurs, but they might not survive us,” said Will McCallum, a campaigner at Greenpeace. “Human activity has put such severe pressure on sea turtle populations around the world that six out of the seven species are threatened with extinction. Without urgent action the situation will only get worse.”

Among many progressive leaders, though, it’s been received eagerly and gratefully. It “helped to put language to tensions and trends facing our movement organizations,” Christopher Torres, an executive director of the Leadership for Democracy and Social Justice institute, said at a Tuesday webinar devoted to the article.

Mitchell’s piece systematically lays out some of the assertions and assumptions that have paralyzed progressive outfits.

Among them are maximalism, or “considering anything less than the most idealistic position” a betrayal; a refusal to distinguish between discomfort and oppression; and reflexive hostility to hierarchy.

He criticizes the insistence “that change on an interpersonal or organizational level must occur before it is sought or practiced on a larger scale,” an approach that keeps activists turned inward, along with the idea that progressive organizations should be places of therapeutic healing.

All the problems Mitchell elucidates have been endemic to the left for a long time. Destructive left-wing purity spirals are at least as old as the French Revolution.

It’s not surprising that such counterproductive tendencies became particularly acute during the pandemic, when people were terrified, isolated and, crucially, very online

“On balance, I think social media has been bad for democracy,” Mitchell told me.

as Mitchell wrote in his essay, social media platforms reward shallow polemics, “self-aggrandizement, competition and conflict.” These platforms can give power to the powerless, but they also bestow it on the most disruptive and self-interested people in any group, those likely to take their complaints to Twitter rather than to their supervisors or colleagues.

The gamification of discourse through likes and retweets, he said, “flies in the face of building solidarity, of being serious about difference, of engaging in meaningful debate and struggle around complex ideas.”

The publication of “Building Resilient Organizations” and the conversation around it are signs that the fever Mitchell describes is beginning to break.

that doesn’t mean the dysfunctions Mitchell identified will go away on their own once people start spending more time together. He puts much of the onus on leaders to be clear with employees about the missions of their organizations and their decision-making processes and to take emotional maturity into account in hiring decisions.

the ultimate aim of social justice work should not be the refinement of one’s own environment. “Building resilient and strong organizations is not the end goal,” said Mitchell. “It’s a means to building power so we can defeat an authoritarian movement that wants to take away democracy.” Here’s to remembering that in 2023.
