He hypothesizes that the process involves one or more molecules released by the nervous system — perhaps small RNAs, perhaps something secreted like a hormone. But somehow those germ cells then influence the behavior of the next generation and seem to circumvent the normal need for rde-4 in the production of the small RNAs for chemotaxis in the progeny.

“I believe that today, there is not a single solid paper showing that only small RNAs are involved in epigenetic inheritance,” said Isabelle Mansuy, a neuroepigenetics researcher at the Swiss Federal Institute of Technology Zurich and the University of Zurich who studies the inheritance of trauma in humans and mice. In the mouse model she works with, she knows that small RNAs are not sufficient because if she injects small RNAs alone into fertilized mouse eggs, the resulting animals do not show the RNA-associated trait.

“If we can ingest a chemical from our environment that changes the epigenomes of the egg or sperm, why couldn’t our brain make a similar molecule that does the same thing?”

Perinatal Depression

Seasonal Affective Disorder (SAD):

Psychotic Depression:

Depression can occur along with other serious illnesses, such as diabetes, cancer, heart disease, and Parkinson’s disease. Depression can make these conditions worse and vice versa.

Depression affects different people in different ways.

Medications called antidepressants can work well to treat depression.

The repercussions of this bias confines us to the same routines, political parties, and economic strategies

our cognitive selective attention processes identify negative news as inherently important or profound

This is the sort of groupthink that convinces religious and political radicals they have greater support

This lack of self-control, where most of us would rather exchange serious pains in the not-to-distant future for menial pleasures in the moment, personifies the impulsive decision-making that has led to the financial meltdown, urban saturation, political corruption, and general slighting of imminent environmental cataclysms.

So while the majority of us may be prone to these errors in rational judgement, we can also be more aware of them. And who knows, if we can manage to re-rationalise how we think, act, and treat one another, perhaps our politics will follow suit.

The Yale-led study investigated the timing of this outgassing by modeling the effects of carbon dioxide and sulfur emissions on global temperatures and comparing them with paleotemperature records spanning the extinction. They found that at least 50% or more of the major outgassing from the Deccan Traps occurred well before the asteroid impact, and only the impact coincided with the mass extinction event.The volcanoes did "cause a warming event," but its effect had gone by the time extinction happened, said Michael Henehan, a former researcher at Yale who is now based at the GFZ German Research Centre for Geosciences.

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.

In 2014, the Pew Research Center asked Americans to rank the “greatest dangers in the world.” A plurality put inequality first, ahead of “religious and ethnic hatred,” nuclear weapons, and environmental degradation. And yet people don’t agree about what, exactly, “equality” means.

One side argues that the city should guarantee procedural equality: it should insure that all students and families are equally informed about and encouraged to study for the entrance exam. The other side argues for a more direct, representation-based form of equality: it would jettison the exam, adopting a new admissions system designed to produce student bodies reflective of the city’s demography

In the past year, for example, New York City residents have found themselves in a debate over the city’s élite public high schools

The complexities of egalitarianism are especially frustrating because inequalities are so easy to grasp. C.E.O.s, on average, make almost three hundred times what their employees make; billionaire donors shape our politics; automation favors owners over workers; urban economies grow while rural areas stagnate; the best health care goes to the richest.

It’s not just about money. Tocqueville, writing in 1835, noted that our “ordinary practices of life” were egalitarian, too: we behaved as if there weren’t many differences among us. Today, there are “premiere” lines for popcorn at the movies and five tiers of Uber;

Inequality is everywhere, and unignorable. We’ve diagnosed the disease. Why can’t we agree on a cure?

In a book based on those lectures, “One Another’s Equals: The Basis of Human Equality,” Waldron points out that people are also marked by differences of skill, experience, creativity, and virtue. Given such consequential differences, he asks, in what sense are people “equal”?

According to the Declaration of Independence, it is “self-evident” that all men are created equal. But, from a certain perspective, it’s our inequality that’s self-evident.

More than twenty per cent of Americans, according to a 2015 poll, agree: they believe that the statement “All men are created equal” is false.

In Waldron’s view, though, it’s not a binary choice; it’s possible to see people as equal and unequal simultaneously. A society can sort its members into various categories—lawful and criminal, brilliant and not—while also allowing some principle of basic equality to circumscribe its judgments and, in some contexts, override them

Egalitarians like Dworkin and Waldron call this principle “deep equality.” It’s because of deep equality that even those people who acquire additional, justified worth through their actions—heroes, senators, pop stars—can still be considered fundamentally no better than anyone else.

In the course of his search, he explores centuries of intellectual history. Many thinkers, from Cicero to Locke, have argued that our ability to reason is what makes us equals.

Other thinkers, including Immanuel Kant, have cited our moral sense.

Some philosophers, such as Jeremy Bentham, have suggested that it’s our capacity to suffer that equalizes us

Waldron finds none of these arguments totally persuasive.

In various religious traditions, he observes, equality flows not just from broad assurances that we are all made in God’s image but from some sense that everyone is the protagonist in a saga of error, realization, and redemption: we’re equal because God cares about how things turn out for each of us.

Waldron himself is taken by Hannah Arendt’s related concept of “natality,” the notion that what each of us share is having been born as a “newcomer,” entering into history with “the capacity of beginning something anew, that is, of acting.”

equality may be not a self-evident fact about human beings but a human-made social construction that we must choose to put into practice.

In the end, Waldron concludes that there is no “small polished unitary soul-like substance” that makes us equal; there’s only a patchwork of arguments for our deep equality, collectively compelling but individually limited.

Equality is a composite idea—a nexus of complementary and competing intuitions.

The blurry nature of equality makes it hard to solve egalitarian dilemmas from first principles. In each situation, we must feel our way forward, reconciling our conflicting intuitions about what “equal” means.

The communities that have the easiest time doing that tend to have some clearly defined, shared purpose. Sprinters competing in a hundred-metre dash have varied endowments and train in different conditions; from a certain perspective, those differences make every race unfair.

By embracing an agreed-upon theory of equality before the race, the sprinters can find collective meaning in the ranked inequalities that emerge when it ends

Perhaps because necessity is so demanding, our egalitarian commitments tend to rest on a different principle: luck.

“Some people are blessed with good luck, some are cursed with bad luck, and it is the responsibility of society—all of us regarded collectively—to alter the distribution of goods and evils that arises from the jumble of lotteries that constitutes human life as we know it.” Anderson, in an influential coinage, calls this outlook “luck egalitarianism.”

This sort of artisanal egalitarianism is comparatively easy to arrange. Mass-producing it is what’s hard. A whole society can’t get together in a room to hash things out. Instead, consensus must coalesce slowly around broad egalitarian principles.

No principle is perfect; each contains hidden dangers that emerge with time. Many people, in contemplating the division of goods, invoke the principle of necessity: the idea that our first priority should be the equal fulfillment of fundamental needs. The hidden danger here becomes apparent once we go past a certain point of subsistence.

a core problem that bedevils egalitarianism—what philosophers call “the problem of expensive tastes.”

The problem—what feels like a necessity to one person seems like a luxury to another—is familiar to anyone who’s argued with a foodie spouse or roommate about the grocery bil

The problem is so insistent that a whole body of political philosophy—“prioritarianism”—is devoted to the challenge of sorting people with needs from people with wants

the line shifts as the years pass. Medical procedures that seem optional today become necessities tomorrow; educational attainments that were once unusual, such as college degrees, become increasingly indispensable with time

Some thinkers try to tame the problem of expensive tastes by asking what a “normal” or “typical” person might find necessary. But it’s easy to define “typical” too narrowly, letting unfair assumptions influence our judgment

an odd feature of our social contract: if you’re fired from your job, unemployment benefits help keep you afloat, while if you stop working to have a child you must deal with the loss of income yourself. This contradiction, she writes, reveals an assumption that “the desire to procreate is just another expensive taste”; it reflects, she argues, the sexist presumption that “atomistic egoism and self-sufficiency” are the human norm. The word “necessity” suggests the idea of a bare minimum. In fact, it sets a high bar. Clearing it may require rethinking how society functions.

In her new book, “Saving Us,” which comes out in September, Hayhoe sets out to answer these questions. Chapter by chapter, she lays out effective strategies for communicating about the urgency of climate change across America’s political divide.

She breaks out categories—originally defined by her colleague Anthony Leiserowitz, at the Yale Program on Climate Change Communication, and other researchers—of attitudes toward global warming: alarmed, concerned, cautious, disengaged, and doubtful. Only the remaining eight per cent of Americans fall into the final category, dismissive.

In the past decade, though, as the scope of the crisis became clear, Democrats began pressing for policies to cut U.S. reliance on fossil fuels, and Republicans were reluctant to commit. Energy companies stepped into the stalemate and began aggressively lobbying politicians, and injecting doubt into the public discourse, to stop such policies from taking effect. “Industry swung into motion to activate the political system in their favor,” Hayhoe said.

“In a study of fifty-six countries, researchers found people’s opinions on climate change to be most strongly correlated not with education and knowledge, but rather with ‘values, ideologies, worldviews and political orientation,’ ”

One salient problem is an aspect of human behavior that researchers have termed “solution aversion.” Solving the climate crisis will require ending our reliance on fossil fuels, which people believe would involve major sacrifice.

“If there’s a problem and we’re not going to fix it, then that makes us bad people,” Hayhoe said. “No one wants to be a bad person.” So instead people are happy to seize on excuses not to take action.

Most are what she calls “science-y sounding objections, and, in the U.S., religious-y sounding objections.”

Hayhoe often hears that the Earth has always heated and cooled according to its own intrinsic cycle, or that God, not humanity, controls the fate of the planet. These objections can then harden into aspects of our political identity.

Hayhoe eschews the term “climate denier,” saying that she has “seen it applied all too often to shut down discussion rather than encourage it.”

So much of this is not about the facts,” Leiserowitz told me later. “It’s about trusting the person the facts come from.”

research has shown her that dismissives are nearly impossible to influence. They are also few enough that it should be possible to build political will around fighting climate change by focussing on others.

“It’s not about the loudest voices,” Hayhoe told me. “It’s about everyone else who doesn’t understand why climate change matters or what they can do about it.”

Leiserowitz told me. His work has revealed, for example, that conversations about the climate tend to be more effective if both speakers share a core value or an aspect of their identity. The most effective climate communicators to conservatives are often people of faith, members of the military, and Republicans who are nevertheless committed to the climate.

“That’s why it’s so important to seek out like-minded groups: winter athletes, parents, fellow birders or Rotarians, or people who share our faith.”

There is a long history within evangelicalism of advocating “creation care,” the belief that God charged humanity with caring for the earth. The Evangelical Environmental Network, which Hayhoe advises, argues that evangelicals should follow a “Biblical mandate to care for creation,”

Hayhoe believes that emphasizing the care of plants and animals is less effective than highlighting the potential dangers for our fellow human beings. “It’s not about saving the planet—it’s about saving us,”

One of her communication strategies is to talk to people about their own observations, which help them connect the realities of their lives to the abstraction of climate change.

With farmers, Hayhoe avoids using the term “climate change,” since the phenomenon is frequently seen as a liberal hoax. “We use the words ‘climate variability’ and ‘long-term trends,’ ” she said.

Scott’s work served another purpose. By showing success with his climate-conscious farming techniques, he might persuade other farmers to join in, potentially becoming the center of what Hayhoe calls a cluster. “I preach to my friends about how well it’s doing,” he said.

I don’t accost people in diners,” she wrote me, later. “I wait until they come to me.”

“As recently as 2008, former speaker of the house Newt Gingrich, a Republican, and current House speaker Nancy Pelosi, a Democrat, cozied up on a love seat in front of the U.S. Capitol to film a commercial about climate change,”

She then directed the conversation to Republican-led free market initiatives to combat climate change by putting a price on carbon emissions. Companies passed their costs onto the rest of us by putting the carbon into the atmosphere, she told Dale, “but what if they had to pay for it? What if, when someone’s house burned down because of a forest fire, the companies making money from selling carbon had to pay a homeowner back?” Dale responded, “Well, I’m in favor of that.”

“It’s so important to educate kids about what’s going on, not to frighten them but to show them they can have a hand in solutions.”

Through the years, she’s developed a system to manage trolls. “It’s been trial and error, error, error,” she said. She now responds once, offering a link to resources.

Most fire back with gendered insults, often plays on her last name, after which she blocks the sender.

ayhoe doesn’t urge guilt on her listeners. She only urges that we change our trajectory. “That’s all repentance means,” she said. “To turn.”

the most important aspect of fighting climate change is pushing for policies that will cut our reliance on fossil fuels. She urges the alarmed to get involved in politics, beginning with lobbying politicians at the local and state level.

she’d come across a book, “Scientists as Prophets: A Rhetorical Genealogy,” that examined the role of prophets in society, beginning with the oracle at Delphi, stretching through the Old Testament, and culminating in the work of modern-day scientists.

Studies show that early adopters help shift the norms of their communities.

Over the next decade, officials managing the main U.S. repositories of climate-related information expect their archives’ total volume to grow from about 83 petabytes today to more than 650 petabytes.

One petabyte of digital memory can hold thousands of feature-length movies, with 650 enough to hold the contents of the Library of Congress 30 times over.

All that information, though, is more than conventional data storage can handle and more than any human mind can readily assimilate,

To accommodate it all, the federal workers tasked with managing the data are moving it into the cloud, which offers almost unlimited memory storage while eliminating the need for scientists to maintain their own on-site archive

archive managers are devising new analytical techniques and adapting a standard format for the data no matter who collected it and who wants to study it.

In essence, they are reinventing climate science from the ground up.

“We are in the midst of a technology evolution,

As of last September, government agencies and private companies had about 900 Earth-orbiting satellites gathering data about our planet, according to the Union of Concerned Scientists. That is almost three times as many as were aloft in 2008. More are being readied for launch.

ASA’s $1 billion Surface Water and Ocean Topography mission will measure Earth’s lakes, rivers and oceans in the first detailed global survey of the planet’s surface water.

That is a drop in the data bucket compared with the space agency’s $1.5 billion Nisar radar imaging satellite, which is scheduled for launch in January 2023. Its sensors will detect movements of the planet’s land, ice sheets and sea ice as small as 0.4 inches, transmitting 80 terabytes of data every day.

With current data handling systems and typical internet connections, it would take a climate researcher about a year to download just four days’ worth of Nisar dat

NASA and NOAA are working with Amazon Web Services, Google Cloud and Microsoft Corp. to move their climate databases into the cloud.

Earlier this year, the United Nations Intergovernmental Panel on Climate Change for the first time used data on past climate behavior to gauge the reliability of climate models for policy makers.

we hope to help people better understand the practices used to reach potential voters on our technologies

In doing so, Mr. Moore and others have pushed climate change from the scientific realm into the political battles already raging over topics like voting rights, abortion and L.G.B.T.Q. issues.

“There is a coordinated effort to chill corporate engagement on these issues,” said Daniella Ballou-Aares

They have worked alongside a nonprofit organization that has run television ads, dispatched roaming billboard trucks and rented out a Times Square billboard criticizing BlackRock for championing what they call woke causes, including environmentalism.

That activism has often put companies at odds with the Republican Party, traditionally the ally of big business.

as pressure has grown from consumers and liberal groups to take action, corporations have warmed to the notion of using capital and markets to create a cleaner economy

When President Trump declared in 2017 that he would pull the United States from the Paris climate accord, more than 2,000 businesses and investors — including Apple, Amazon and Mars — signed a pledge to continue to work toward climate goals.

“Every company and every industry will be transformed by the transition to a net-zero world,” Mr. Fink wrote. “The question is, will you lead, or will you be led?”

And in January, Mr. Moore pulled about $20 million out of a fund managed by BlackRock because the firm has encouraged other companies to reduce emissions. BlackRock still manages several billion for West Virginia’s state retirement system. “We’re divesting from BlackRock because they’re divesting from us,” Mr. Moore said in an interview.

“These big banks are virtue signaling because they are woke,”

Mr. Fink of BlackRock has emerged as a main target of conservatives.

“We are perhaps the world’s largest investor in fossil fuel companies, and, as a long-term investor in these companies, we want to see these companies succeed and prosper,” BlackRock’s head of external affairs, Dalia Blass, wrote in a letter to Texas regulators in January.

“BlackRock is trying to have it all ways, acting like it is trying to please everyone.”

“ESG is a scam,” he said on Twitter on this month. “It has been weaponized by phony social justice warriors.” Shortly after that he shared a meme that declared an ESG score “determines how compliant your business is with the leftist agenda.”

“Climate change is not a financial risk that we need to worry about,” adding, “Who cares if Miami is six meters underwater in 100 years?”

That view is at odds with the findings of the world’s leading climate scientists. A major United Nations report warned last month that the world could reach a threshold by the end of this decade beyond which the dangers of global warming — including worsening floods, droughts and wildfires — will grow considerably. In 2021, there were 20 weather or climate-related disasters in the United States that each cost more than $1 billion in losses, according to the federal government.

“Our ambition is to be the leading bank supporting the global economy in the transition to net zero,” he said.

The law, for instance, establishes a new $20 billion Directorate for Technology, which will specialize in pushing new technologies from the prototype stage into the mass market. It is meant to prevent what happened with the solar industry—where America invented a new technology, only to lose out on commercializing it—from happening again

Within a few years, when the funding has fully ramped up, the government will spend roughly $80 billion a year on accelerating the development and deployment of zero-carbon energy and preparing for the impacts of climate change. That exceeds the GDP of about 120 of the 192 countries that have signed the Paris Agreement on Climate Change

By the end of the decade, the federal government will have spent more than $521 billion

the bill’s programs focus on the bleeding edge of the decarbonization problem, investing money in technology that should lower emissions in the 2030s and beyond.

The International Energy Association has estimated that almost half of global emissions reductions by 2050 will come from technologies that exist only as prototypes or demonstration projects today.

To get those technologies ready in time, we need to deploy those new ideas as fast as we can, then rapidly get them to commercial scale, Carey said. “What used to take two decades now needs to take six to 10 years.” That’s what the CHIPS Act is supposed to do

When viewed with the Inflation Reduction Act, which the House is poised to pass later this week, and last year’s bipartisan infrastructure law, a major shift in congressional climate spending comes into focus. According to the RMI analysis, these three laws are set to more than triple the federal government’s average annual spending on climate and clean energy this decade, compared with the 2010s.

Congress has explicitly tasked the new office with studying “natural and anthropogenic disaster prevention or mitigation” as well as “advanced energy and industrial efficiency technologies,” including next-generation nuclear reactors.

The bill also directs about $12 billion in new research, development, and demonstration funding to the Department of Energy, according to RMI’s estimate. That includes doubling the budget for ARPA-E, the department’s advanced-energy-projects skunk works.

it allocates billions to upgrade facilities at the government’s in-house defense and energy research institutes, including the National Renewable Energy Laboratory, the Princeton Plasma Physics Laboratory, and Berkeley Lab, which conducts environmental-science research.

RMI’s estimate of the climate spending in the CHIPS bill should be understood as just that: an estimate. The bill text rarely specifies how much of its new funding should go to climate issues.

When you add CHIPS, the IRA, and the infrastructure law together, Washington appears to be unifying behind a new industrial policy, focused not only on semiconductors and defense technology but clean energy

The three bills combine to form a “a coordinated, strategic policy for accelerating the transition to the technologies that are going to define the 21st century,”

scholars and experts have speculated about whether industrial policy—the intentional use of law to nurture and grow certain industries—might make a comeback to help fight climate change. Industrial policy was central to some of the Green New Deal’s original pitch, and it has helped China develop a commanding lead in the global solar industry.

“Industrial policy,” he said, “is back.”

Why some people can shake off the impulse to eat, and other people stay mired in thoughts about food, is “the million-dollar question,”

There’s another theoretical framework for why Ozempic might quash food noise: Semaglutide activates receptors for a hormone called GLP-1. Studies in animals have shown those receptors are found in cells in regions of the brain that are particularly important for motivation and reward, pointing to one potential way semaglutide could influence cravings and desires.

Ms. Klemmer said she worried about the potential long-term side effects of a medication she might be on for the rest of her life. But she thinks the trade-off — the end of food noise — is worth it. “It’s worth every bad side effect that I’d have to go through to have what I feel now,” she said: “not caring about food.”

we’re networked organisms who move around in shifting surroundings, environments that have the power to transform our thinking

Annie Murphy Paul’s new book, “The Extended Mind,” which exhorts us to use our entire bodies, our surroundings and our relationships to “think outside the brain.”

In 2011, she published “Origins,” which focused on all the ways we are shaped by the environment, before birth and minute to minute thereafter.

“In the nature-nurture dynamic, nurture begins at the time of conception. The food the mother eats, the air she breathes, the water she drinks, the stress or trauma she experiences — all may affect her child for better or worse, over the decades to come.”

a down-to-earth take on the science of epigenetics — how environmental signals become catalysts for gene expression

the parallel to this latest book is that the boundaries we commonly assume to be fixed are actually squishy. The moment of a child’s birth, her I.Q. scores or fMRI snapshots of what’s going on inside her brain — all are encroached upon and influenced by outside forces.

awareness of our internal signals, such as exactly when our hearts beat, or how cold and clammy our hands are, can boost our performance at the poker table or in the financial markets, and even improve our pillow talk

“Though we typically think of the brain as telling the body what to do, just as much does the body guide the brain with an array of subtle nudges and prods. One psychologist has called this guide our ‘somatic rudder,’

The “body scan” aspect of mindfulness meditation that has been deployed by the behavioral medicine pioneer Jon Kabat-Zinn may help people lower their heart rates and blood pressure,

techniques that help us pinpoint their signals can foster well-being

Tania Singer has shown how the neural circuitry underlying compassion is strengthened by meditation practice

our thoughts “are powerfully shaped by the way we move our bodies.” Gestures help us understand spatial concepts; indeed, “without gesture as an aid, students may fail to understand spatial ideas at all,”

looking out on grassy expanses near loose clumps of trees and a source of water helps us solve problems. “Passive attention,” she writes, is “effortless: diffuse and unfocused, it floats from object to object, topic to topic. This is the kind of attention evoked by nature, with its murmuring sounds and fluid motions; psychologists working in the tradition of James call this state of mind ‘soft fascination.’”

The chapters on the ways natural and built spaces reflect universal preferences and enhance the thinking process felt like a respite

Gelfand and Harrington predicted that “‘tight’ states would exhibit a higher incidence of natural disasters, greater environmental vulnerability, fewer natural resources, greater incidence of disease and higher mortality rates, higher population density, and greater degrees of external threat.”

The South dominated the tight states: Mississippi, Alabama Arkansas, Oklahoma, Tennessee, Texas, Louisiana, Kentucky, South Carolina and North Carolina

states in New England and on the West Coast were the loosest: California, Oregon, Washington, Maine, Massachusetts, Connecticut, New Hampshire and Vermont.

Cultural differences, Gelfand continued, “have a certain logic — a rationale that makes good sense,” noting that “cultures that have threats need rules to coordinate to survive (think about how incredibly coordinated Japan is in response to natural disasters).

“Rule Makers, Rule Breakers: How Tight and Loose Cultures Wire the World” in 2018, in which she described the results of a 2016 pre-election survey she and two colleagues had commissioned

The results were telling: People who felt the country was facing greater threats desired greater tightness. This desire, in turn, correctly predicted their support for Trump. In fact, desired tightness predicted support for Trump far better than other measures. For example, a desire for tightness predicted a vote for Trump with 44 times more accuracy than other popular measures of authoritarianism.

The 2016 election, Gelfand continued, “turned largely on primal cultural reflexes — ones that had been conditioned not only by cultural forces, but by a candidate who was able to exploit them.”

Gelfand said:Some groups have much stronger norms than others; they’re tight. Others have much weaker norms; they’re loose. Of course, all cultures have areas in which they are tight and loose — but cultures vary in the degree to which they emphasize norms and compliance with them.

In both 2016 and 2020, Donald Trump carried all 10 of the top “tight” states; Hillary Clinton and Joe Biden carried all 10 of the top “loose” states.

The tight-loose concept, Gelfand argued,is an important framework to understand the rise of President Donald Trump and other leaders in Poland, Hungary, Italy, and France,

cultures that don’t have a lot of threat can afford to be more permissive and loose.”

The gist is this: when people perceive threat — whether real or imagined, they want strong rules and autocratic leaders to help them survive

My research has found that within minutes of exposing study participants to false information about terrorist incidents, overpopulation, pathogen outbreaks and natural disasters, their minds tightened. They wanted stronger rules and punishments.

Gelfand writes that tightness encourages conscientiousness, social order and self-control on the plus side, along with close-mindedness, conventional thinking and cultural inertia on the minus side.

Looseness, Gelfand posits, fosters tolerance, creativity and adaptability, along with such liabilities as social disorder, a lack of coordination and impulsive behavior.

If liberalism and conservatism have historically played a complementary role, each checking the other to constrain extremism, why are the left and right so destructively hostile to each other now, and why is the contemporary political system so polarized?

Along the same lines, if liberals and conservatives hold differing moral visions, not just about what makes a good government but about what makes a good life, what turned the relationship between left and right from competitive to mutually destructive?

As a set, Niemi wrote, conservative binding values encompassthe values oriented around group preservation, are associated with judgments, decisions, and interpersonal orientations that sacrifice the welfare of individuals

She cited research thatfound 47 percent of the most extreme conservatives strongly endorsed the view that “The world is becoming a more and more dangerous place,” compared to 19 percent of the most extreme liberals

Conservatives and liberals, Niemi continued,see different things as threats — the nature of the threat and how it happens to stir one’s moral values (and their associated emotions) is a better clue to why liberals and conservatives react differently.

Unlike liberals, conservatives strongly endorse the binding moral values aimed at protecting groups and relationships. They judge transgressions involving personal and national betrayal, disobedience to authority, and disgusting or impure acts such as sexually or spiritually unchaste behavior as morally relevant and wrong.

Underlying these differences are competing sets of liberal and conservative moral priorities, with liberals placing more stress than conservatives on caring, kindness, fairness and rights — known among scholars as “individualizing values

conservatives focus more on loyalty, hierarchy, deference to authority, sanctity and a higher standard of disgust, known as “binding values.”

Niemi contended that sensitivity to various types of threat is a key factor in driving differences between the far left and far right.

For example, binding values are associated with Machiavellianism (e.g., status-seeking and lying, getting ahead by any means, 2013); victim derogation, blame, and beliefs that victims were causal contributors for a variety of harmful acts (2016, 2020); and a tendency to excuse transgressions of ingroup members with attributions to the situation rather than the person (2023).

Niemi cited a paper she and Liane Young, a professor of psychology at Boston College, published in 2016, “When and Why We See Victims as Responsible: The Impact of Ideology on Attitudes Toward Victims,” which tested responses of men and women to descriptions of crimes including sexual assaults and robberies.

We measured moral values associated with unconditionally prohibiting harm (“individualizing values”) versus moral values associated with prohibiting behavior that destabilizes groups and relationships (“binding values”: loyalty, obedience to authority, and purity)

Increased endorsement of binding values predicted increased ratings of victims as contaminated, increased blame and responsibility attributed to victims, increased perceptions of victims’ (versus perpetrators’) behaviors as contributing to the outcome, and decreased focus on perpetrators.

A central explanation typically offered for the current situation in American politics is that partisanship and political ideology have developed into strong social identities where the mass public is increasingly sorted — along social, partisan, and ideological lines.

What happened to people ecologically affected social-political developments, including the content of the rules people made and how they enforced them

Just as ecological factors differing from region to region over the globe produced different cultural values, ecological factors differed throughout the U.S. historically and today, producing our regional and state-level dimensions of culture and political patterns.

Joshua Hartshorne, who is also a professor of psychology at Boston College, took issue with the binding versus individualizing values theory as an explanation for the tendency of conservatives to blame victims:

I would guess that the reason conservatives are more likely to blame the victim has less to do with binding values and more to do with the just-world bias (the belief that good things happen to good people and bad things happen to bad people, therefore if a bad thing happened to you, you must be a bad person).

Belief in a just world, Hartshorne argued, is crucial for those seeking to protect the status quo:It seems psychologically necessary for anyone who wants to advocate for keeping things the way they are that the haves should keep on having, and the have-nots have got as much as they deserve. I don’t see how you could advocate for such a position while simultaneously viewing yourself as moral (and almost everyone believes that they themselves are moral) without also believing in the just world

Conversely, if you generally believe the world is not just, and you view yourself as a moral person, then you are likely to feel like you have an obligation to change things.

I asked Lene Aaroe, a political scientist at Aarhus University in Denmark, why the contemporary American political system is as polarized as it is now, given that the liberal-conservative schism is longstanding. What has happened to produce such intense hostility between left and right?

There is variation across countries in hostility between left and right. The United States is a particularly polarized case which calls for a contextual explanatio

I then asked Aaroe why surveys find that conservatives are happier than liberals. “Some research,” she replied, “suggests that experiences of inequality constitute a larger psychological burden to liberals because it is more difficult for liberals to rationalize inequality as a phenomenon with positive consequences.”

Numerous factors potentially influence the evolution of liberalism and conservatism and other social-cultural differences, including geography, topography, catastrophic events, and subsistence styles

Steven Pinker, a professor of psychology at Harvard, elaborated in an email on the link between conservatism and happiness:

t’s a combination of factors. Conservatives are likelier to be married, patriotic, and religious, all of which make people happier

They may be less aggrieved by the status quo, whereas liberals take on society’s problems as part of their own personal burdens. Liberals also place politics closer to their identity and striving for meaning and purpose, which is a recipe for frustration.

Some features of the woke faction of liberalism may make people unhappier: as Jon Haidt and Greg Lukianoff have suggested, wokeism is Cognitive Behavioral Therapy in reverse, urging upon people maladaptive mental habits such as catastrophizing, feeling like a victim of forces beyond one’s control, prioritizing emotions of hurt and anger over rational analysis, and dividing the world into allies and villains.

Why, I asked Pinker, would liberals and conservatives react differently — often very differently — to messages that highlight threat?

It may be liberals (or at least the social-justice wing) who are more sensitive to threats, such as white supremacy, climate change, and patriarchy; who may be likelier to moralize, seeing racism and transphobia in messages that others perceive as neutral; and being likelier to surrender to emotions like “harm” and “hurt.”

While liberals and conservatives, guided by different sets of moral values, may make agreement on specific policies difficult, that does not necessarily preclude consensus.

there are ways to persuade conservatives to support liberal initiatives and to persuade liberals to back conservative proposals:

While liberals tend to be more concerned with protecting vulnerable groups from harm and more concerned with equality and social justice than conservatives, conservatives tend to be more concerned with moral issues like group loyalty, respect for authority, purity and religious sanctity than liberals are. Because of these different moral commitments, we find that liberals and conservatives can be persuaded by quite different moral arguments

For example, we find that conservatives are more persuaded by a same-sex marriage appeal articulated in terms of group loyalty and patriotism, rather than equality and social justice.

Liberals who read the fairness argument were substantially more supportive of military spending than those who read the loyalty and authority argument.

We find support for these claims across six studies involving diverse political issues, including same-sex marriage, universal health care, military spending, and adopting English as the nation’s official language.”

In one test of persuadability on the right, Feinberg and Willer assigned some conservatives to read an editorial supporting universal health care as a matter of “fairness (health coverage is a basic human right)” or to read an editorial supporting health care as a matter of “purity (uninsured people means more unclean, infected, and diseased Americans).”

Conservatives who read the purity argument were much more supportive of health care than those who read the fairness case.

“political arguments reframed to appeal to the moral values of those holding the opposing political position are typically more effective

In “Conservative and Liberal Attitudes Drive Polarized Neural Responses to Political Content,” Willer, Yuan Chang Leong of the University of Chicago, Janice Chen of Johns Hopkins and Jamil Zaki of Stanford address the question of how partisan biases are encoded in the brain:

society. How do such biases arise in the brain? We measured the neural activity of participants watching videos related to immigration policy. Despite watching the same videos, conservative and liberal participants exhibited divergent neural responses. This “neural polarization” between groups occurred in a brain area associated with the interpretation of narrative content and intensified in response to language associated with risk, emotion, and morality. Furthermore, polarized neural responses predicted attitude change in response to the videos.

The four authors argue that their “findings suggest that biased processing in the brain drives divergent interpretations of political information and subsequent attitude polarization.” These results, they continue, “shed light on the psychological and neural underpinnings of how identical information is interpreted differently by conservatives and liberals.”

The authors used neural imaging to follow changes in the dorsomedial prefrontal cortex (known as DMPFC) as conservatives and liberals watched videos presenting strong positions, left and right, on immigration.

or each video,” they write,participants with DMPFC activity time courses more similar to that of conservative-leaning participants became more likely to support the conservative positio

Conversely, those with DMPFC activity time courses more similar to that of liberal-leaning participants became more likely to support the liberal position. These results suggest that divergent interpretations of the same information are associated with increased attitude polarizatio

Together, our findings describe a neural basis for partisan biases in processing political information and their effects on attitude change.

Describing their neuroimaging method, the authors point out that theysearched for evidence of “neural polarization” activity in the brain that diverges between people who hold liberal versus conservative political attitudes. Neural polarization was observed in the dorsomedial prefrontal cortex (DMPFC), a brain region associated with the interpretation of narrative content.

The question is whether the political polarization that we are witnessing now proves to be a core, encoded aspect of the human mind, difficult to overcome — as Leong, Chen, Zaki and Willer sugges

— or whether, with our increased knowledge of the neural basis of partisan and other biases, we will find more effective ways to manage these most dangerous of human predispositions.
