On Loyal Liars, Fact-Checkers, and Why We’re Bumping into Things
Both truth and lies serve overarching social purposes. The better we understand those purposes and the choices entailed in pursuing them, the better we’ll understand ourselves, each other, and the society around us.
Apr 11, 2026
Sorting fact from fiction in statements by President Donald Trump and members of his administration can be demoralizing and cringe inducing. The ratio of untruths to truths is astonishing—and many of the lies seem almost pointlessly cruel.
Trump lies at a pace that’s puzzling. What conceivable purpose could this behavior serve? And why are his most transparent lies so enthusiastically parroted by his underlings?
My aim in this article is not to engage in partisan lie shaming, but rather to better understand human nature. Why do people—and especially large groups of people—spew and cling to falsehoods?
As we’ll see, the distinction between truth and untruth is fuzzy at the edges, and discussions about the nature of truth can quickly spiral into rarefied philosophizing. In this article, we’ll entertain the centuries-old philosophical question, “What is truth?” only to the degree that’s useful in helping clarify my main thesis—which is that both truth and lies serve overarching social purposes. The better we understand those purposes and the choices entailed in pursuing them, the better we’ll understand ourselves, each other, and the society around us—and the better we will navigate the Great Unraveling which lies before us.
The Social Usefulness of Lies
Lies told by individuals typically serve some immediate need—often to avoid blame or to improve one’s status in the eyes of others. However, lies also serve a larger social function arising from human social evolution.
Kaivan Shroff hinted at that function in a recent article about Department of Homeland Security spokesperson Tricia McLaughlin, whose untruthful statements to the press are widely documented. What’s interesting is Shroff’s speculation on why McLaughlin lies so much:
The reason McLaughlin and other people who speak on behalf of the administration say things on television that are demonstrably false is not to try to convince ambivalent people of the merits of Trump’s policy decisions. Persuasion is not their objective. Their objective is instead to offer a demonstration of loyalty to the president and his political project—costly loyalty: The price is their own credibility. The more indefensible a claim, the clearer the signal.
Shroff is saying that, for McLaughlin, status within her social group—i.e., the Trump administration—outweighs accuracy or veracity.
Shroff’s explanation dovetails nicely with the discussion of social evolution in my book Power: Limits and Prospects for Human Survival. As humans developed prodigious linguistic ability, we evolved to become an ultra-social species. There are many other social species (ants, bees, chimps, chickens, crows, and more), but symbolic language greatly amplifies sociality, heightening both its advantages and costs.
Lacking language, many other species still engage in deception (like the mimic octopus, which impersonates toxic sea creatures to discourage its potential predators). But language opens the door to fiction, exaggeration, and just plain fibbing on a scale that no other creature can begin to match. Also, our main targets for deception aren’t other species, but members of our own kind who use the same language.
The biggest advantage of sociality is that greater cohesion among individuals makes any given group more powerful vis-à-vis other groups of similar size. While increased cohesion yields a payoff for the group, there is also a payoff for individual members: Acceptance by a cohort confers a sense of security. Alone, life is dangerous and hard. But if you’re with a tribe, there’s the sense that others have your back. Indeed, we all tend to feel strong psychological pressures to align with any social group in which we want to maintain membership.
Lying is not the only possible demonstration of group loyalty. In “big god” religions, tithing, self-flagellation, and long pilgrimages emerged long ago as signs of sincere dedication to the faith. The key factor in such signs was their costliness: The more costly the demonstration, the greater the payoff in proof of group loyalty and therefore status in the group.
A price of entry for at least for some religious and political groups is belief in absurdities. Examples range from Christianity’s doctrine of the virgin birth to Stalin’s requirement that his followers give credence to his personal infallibility (George Orwell famously satirized such political gullibility mandates in his 1948 novel, 1984, wherein the sole function of the government’s “Ministry of Truth” was to create false historical records and news to align with the Party’s ever-changing narrative).
Absurdities are an affront to common sense, so believers must expend constant effort to justify them. This need for justification creates an employment niche for apologists. Theologians’ justifications for absurdities and contradictions in sacred texts have ranged from simple literalism (“the Bible tells me so”) to earnest hunts for allegorical and metaphorical meaning. For example, Episcopal Bishop John Shelby Spong says the virgin birth isn’t so much a fact as a teaching story meant to symbolize a new beginning for humanity. Such metaphorical interpretations relieve the anxiety that results from too much effort spent justifying an absurdity; in effect, they offer membership in the group at a discounted rate. Nevertheless, the absurdity still stands as a gateway test of group membership.
The Usefulness of Fact-Checking
The problem with lies is that, if you believe them, you can bump into things. If you believe a lie that there is no wall in front of you when there is in fact a wall, a few forward steps can induce severe cognitive dissonance. And if the collision occurs at a brisk gait, you might get a bloody nose or worse.
Here’s a familiar real-world example. In 2002 and 2003, members of the George W. Bush administration repeatedly made the case that Iraq was developing weapons of mass destruction and that the United States must therefore attack the country and overthrow its government. Bombers flew, troops invaded, hundreds of thousands died, and Saddam Hussein’s regime fell. But the war is now generally regarded as having been a grave mistake and a strategic failure due to the ensuing destabilization of the region. The supposed Iraqi weapons of mass destruction were never found, and Americans’ trust in government never recovered.
Individually and collectively, we need an accurate understanding of reality if we are to survive and thrive. Sometimes that’s easy: Facts can be plain to see and agreed upon by nearly everyone. Other times they can require hard work, math, and instrumentation to ascertain—and they may still remain controversial.
While factual truths are fragile and evolving, they are essential to a free society, serving as a necessary anchor for public opinion.
As important as microscopes, telescopes, and other sensory augmentations of the modern era are to grasping reality, certain mental habits and methodologies are even more essential. Those habits and methodologies have a history. Indigenous peoples used logic routinely, and the basic functions of reason have been observed in many nonhuman species. Aristotle (4th century BCE) has long been credited with the invention of formal (i.e., written) logic, but thinkers in India and China made independent similar contributions that were arguably as early. Later, Middle Eastern philosophers added mathematical rigor to the process of disciplined thinking. In the 17th and 18th centuries, the founders of modern science applied logic to the assessment of evidence from the natural world using a method that rigorously tests hypotheses—the scientific method. This method differs profoundly from the usual procedure of political or legal debaters, who gather and present evidence that supports their thesis. Scientists instead continually look for evidence to disprove their hypotheses, so they can improve or replace them.
Science has produced immense amounts of reliable information about the world and about us. However, scientists are still human and still susceptible to political and social influences. As Thomas Kuhn explained in his groundbreaking book The Structure of Scientific Revolutions (1962), major breakthroughs in science occur as the result of a long accumulation of anomalies that cannot be explained by existing theories. However, despite the existence of these anomalies, until a clearly better theory comes along scientists often tend to close ranks around the existing theory.
This happened, for example, in the field of geology, which in the 19th century was confronted by evidence of vast changes to rocks and ecosystems throughout hundreds of millions of years of Earth history. Wishing to distance themselves from theologians who saw such evidence as confirming the biblical story of Noah’s Flood, geologists developed the doctrine of uniformitarianism, which held that all geological evidence should be explained by slow processes (mostly erosion and deposition) that can be observed at work today. A few geologists protested, saying that the evidence also suggested occasional catastrophic events of which there are no ongoing examples, but until the 1970s these catastrophists were largely prevented from publishing prominently. Anomalies kept accumulating until it became clear that events like mass extinctions could only be explained in catastrophist terms. Today it’s fair to say that all geologists are part-time catastrophists.
French philosopher-anthropologist Bruno Latour (1947-2022) argued that all scientific knowledge is socially constructed. In his book Laboratory Life: The Social Construction of Scientific Facts (1979), he described facts not as objective truths waiting to be discovered, but as descriptions of the world that are generated within social networks of scientists. The exact extent to which commercial and social interests shape science is a question that echoes through today’s vaccine controversies.
Science is always changing. One year, drinking red wine is proclaimed to be good for you. A couple of years later, the same authorities say drinking any alcohol is bad. Science’s tendency to evolve is its virtue, but also its vulnerability: Many people assume that, because scientific understandings change, scientists are therefore often wrong and really don’t know much. Why bother learning what scientists think now when the consensus is bound to shift later? Hence the persistence of flat Earth believers.
Further, there are important questions science can’t answer. What existed before the Big Bang? Is there a creative principle behind the universe that could be equated with God? What is a good life? Methodically probing physical evidence won’t tell you.
Nevertheless, science has proven to be a useful tool in clarifying most day-to-day issues. If you’re a bridge builder and you want to know the tensile strength of a particular kind of steel, you can consult the outcomes of repeated experiments and have confidence in the numbers. Even though scientists can sometimes be swayed by social motives, that’s not a reason for abandoning science altogether, just for doing it better.
“Facts” are simply the current numbers, descriptions, and interpretations agreed upon by experts, based on the best current evidence. Yes, facts can be socially influenced and can change as new data emerges. But fact-checkers still have value. They’re usually right. They’re good at exposing lies. And, as we’ve seen, lies have consequences.
Foucault and Arendt
Social evolution theory isn’t the final word on why groups of people create false representations of reality. Two 20th century thinkers had some relevant insights on knowledge, truth, and lies that I need to touch upon here before we proceed.
French historian Michel Foucault (1926-1984) claimed that knowledge is constructed through systems of power and discourse. His concept of “power-knowledge” (pouvoir-savoir) asserts that power and knowledge are inextricable, and fundamental to the organization of societies. While power can operate through simple coercion, it also achieves its ends through discourse, defining “truths” that categorize, regulate, and control individual actions, making knowledge a force that shapes reality.
Foucault argued that knowledge is never neutral; it is always linked to power. Conversely, power is exercised through the creation and application of knowledge. Power isn’t merely repressive (saying “no”) but also productive, as it generates knowledge, discourse, and new ways of understanding the self and the world. Institutions (like medicine, psychiatry, and prisons) produce “truths” that determine what is “normal” or “abnormal.” These, in turn, regulate behavior and justify power structures.
Hannah Arendt (1906-1975) was a historian and philosopher who lived through the rise of Nazism in Germany before emigrating to the US. She argued that authoritarian power thrives not just by forcing people to believe lies, but by destroying their capacity to distinguish truth from falsehood, thereby inducing cynicism. By constantly changing fabricated narratives, totalitarian regimes destroy the factual basis of society, leaving citizens unable to think, judge, or act. The aim is to create a world where nothing is believed, resulting in a population that can no longer distinguish right from wrong, truth from lies. When people stop believing anything, they become “ideal subjects” for totalitarian rule because they stop caring about what’s true.
Arendt noted that totalitarian leaders try to replace factual truth with a fabricated, consistent narrative that feels more appealing than reality. While factual truths are fragile and evolving, they are essential to a free society, serving as a necessary anchor for public opinion.
Where We Are Now: Nothing Is True, Nothing Matters, and We’re Bumping into Bigger and Bigger Things
There’s a significant difference between a social reality in which experts and the public alike value truth but are often deceived via the influences of financial and political power (i.e., the situation described by Foucault), and a social reality in which elites pursue power at any cost, routinely asserting patent lies and deliberately undermining society’s commitment to reason as ways to exert and extend their advantages (the situation described by Arendt). Foucault was describing the social production of knowledge in most modern industrial societies; Arendt focused specifically on authoritarian, totalitarian states. With Trump in charge, the US is careening toward the latter condition.
Confirming this, Adam Serwer argues in a recent article that “gullicism” (a portmanteau of “gullibility” and “cynicism”) is the tenor of present-day America:
Gullicists see everyone’s hidden motives—except when they don’t. They are able to reject any claim rooted in actual evidence—whether in science, politics, or history—while embracing the most breathtakingly absurd assertions on the same topics. Indeed, documentation is often taken as further evidence of conspiracy, while assertion (that this or that will "detoxify" your blood or that COVID deaths were exaggerated) is taken as gospel.
Unsurprisingly, as gullicism spreads, we’re increasingly bumping into things, including:
- The disastrous Iran war, which is not simply based on lies (like the Iraq war), but on shifting and conflicting lies;
- A chaotic and short-staffed Justice Department that’s no longer able to investigate real criminals due to the Trump administration’s prosecutions of political enemies, which consume staff time, routinely fall apart due to lack of evidence, and cause mass resignations of career prosecutors (like science, the criminal justice system is ideally a search for truth and relies on evidence); and
- Entirely preventable measles outbreaks resulting from the Department of Health and Human Services’ spreading of scientifically questionable opinions and reversal of longstanding vaccine policies.
In some ways the ascent of Trumpism represents a contest between followers of the 18th century European Enlightenment, who still value reason and democracy, and those who say the Enlightenment was a mistake. In place of reason and democracy, Peter Thiel and other MAGA intellectual leaders promote an authoritarian “dark enlightenment.” But it’s a simple truism: In the dark, you’re more likely to bump into things.
If we don’t want to bump into more things, we must hold to logic and evidence. But we can’t do so in isolation. We’re all consumers of information, and now more than ever it’s essential to make a habit of evaluating our information sources for trustworthiness—based not on what “feels right” or what our social group thinks, but on a demonstrated consistency in testing statements.
Because we’re an ultra-social species with language, the tendency toward loyal lying will always be with us. We’ll never eliminate all lies, either personal or collective. But at this moment in history, as we face climate change and a Great Unraveling, we have a rough ride ahead of us one way or another, and the last thing we need is a sudden proliferation of fake road maps.

As Trump Pushes 'Polluters First Agenda,' 2027 Budget Blasted as 'Bloody New Deal'
"This proposed budget is exactly what America does NOT need when facing rising energy bills, more frequent extreme weather, and rising insurance rates," said one climate campaigner.
Apr 03, 2026
US President Donald Trump continued his "war on science" on Friday with his budget request for the 2027 fiscal year, which critics have denounced as "grossly irresponsible" for its proposed $1.5 trillion in military spending and "a moral obscenity" because of its cuts to social and scientific programs.
In the lead-up to Trump's request to the Republican-controlled Congress, as he and Israel waged war on Iran, Sean Manning, a Herbert Scoville Jr. Peace Fellow in the Union of Concerned Scientists' Global Security Program, wrote that "if this Bloody New Deal actually passes, it could give unparalleled increases in financial power to defense contractors and support for the political work they already do to influence Congress."
"Sane voices need to act now, building opposition to this unprecedented plan," Manning argued. "Progressives should be unflinching in defining this proposal as a blank check for the same contractors who cannot deliver ships on time, munitions at scale, or clean audits. Pouring funds into a defense sector that has repeatedly failed basic tests of accountability will not miraculously produce innovation."
In addition to railing against the budget for the Pentagon—the world's largest institutional climate polluter—after it was officially released on Friday, progressive voices directed attention to some particular proposed cuts and their consequences.
To fund the Pentagon's massive war-making budget, "the Trump administration is requesting the cancellation of billions of dollars in funds for renewable energy, environmental justice, carbon removal, space science, and climate change education," Emily Gardner reported Friday for Eos, the American Geophysical Union's news magazine.
As Katherine Tsantiris, Ocean Conservancy's director of government relations, pointed out, among the targeted federal agencies is the National Oceanic and Atmospheric Administration (NOAA). The proposed cuts, she said, "fly directly in the face of the clear bipartisan support Congress showed earlier this year by protecting funding for this critical agency."
"Slashing NOAA's budget would weaken weather forecasting, disrupt fisheries management, and stall ocean research—putting American lives, livelihoods, and global scientific leadership at risk," Tsantiris continued. "Congress should once again reject these cuts to ensure NOAA has the resources it needs to support our economy, protect our ocean, and keep Americans safe."
Quentin Scott, federal policy director at the Chesapeake Climate Action Network Action Fund, argued that "this proposed budget is exactly what America does NOT need when facing rising energy bills, more frequent extreme weather, and rising insurance rates."
"By gutting funds for climate science and innovation, the budget jeopardizes our ability to understand and respond to the accelerating climate crisis," Scott said. "Defunding climate research at NOAA doesn't make the problem go away—it makes those hazards more dangerous and more expensive. Families across the country are already paying the price through higher utility bills, flooding, and storm damage. This budget would only make those burdens worse."
Big Oil-backed Trump's budget proposal came on the heels of devastating flooding in Hawaii and as high temperatures hit the Western United States. It also followed an annual World Meteorological Organization report on the fossil fuel-driven climate emergency, which last month led UN Secretary-General António Guterres to declare that "every key climate indicator is flashing red."
Devastating.

Trump also proposed slashing the Environmental Protection Agency's budget—amid calls to oust Administrator Lee Zeldin for "so brazenly" betraying the EPA's core mission to "protect human health and the environment." Trump also proposed cutting the agency's budget. Noting that attack, Climate Action Campaign director Margie Alt described the president's plan as "anything but a serious" one and "a declaration of who this administration is willing to let suffer."
In a nod to some of the rich executives whose campaign cash helped Trump return to power after promising to scrap his predecessor's climate policies and to enact a "drill, baby, drill" agenda, Alt also called it "a reiteration of this president's devotion to fossil fuel interests."
"This budget would slash the EPA budget by 52%, gutting the agency's ability to protect the air our children breathe, the water our families drink, and the communities that already bear the worst of extreme weather and climate change," she said. "It is a deliberately callous choice to remove the protections that keep families safe, healthy, and shielded from the impacts of pollution and climate change."
According to Alt:
This is not just a continuation of last year's rollbacks. It is an escalation of the Trump administration's Polluters First Agenda and their assault on public health safeguards. Since January 2025, among other abuses, this administration has fired 600 National Weather Service staff, proposed eliminating critical climate research institutions, waived mercury pollution standards for 60 dirty power plants, and gutted the Clean Air Act. This budget is the Trump administration's payback for their big oil, coal, and gas friends and contributors. It slashes resources for clean energy, it zeroes out environmental justice, and pushes oil, gas, and coal, at a time when prices for these energy sources are skyrocketing.
Never before have we had an administration that so blatantly treats American lives as expendable, as proven by this budget. Congress must reject this inhumane budget in full. The American people deserve a federal government that protects them, not one that trades their health, their safety, and their futures for big oil, coal, and gas profits.
As Gardner reported, Trump's budget also "proposes consolidating the Endangered Species Act and Marine Mammal Protection Act, but did not provide details outside noting the program would be housed at the Department of the Interior," among other changes and cuts.
Chris Westfall, senior government relations legislative counsel at Defenders of Wildlife, said that "the administration is yet again demanding that an overworked and grossly understaffed federal workforce do more with less. The proposed budget recklessly consolidates US Fish and Wildlife Service and National Marine Fisheries without the needed resources to preserve scientific expertise, opens our lands and waters to extractive industries, and hollows out the already strained workforce that provides crucial conservation work."
"This proposed budget pushes us further in the wrong direction—potentially triggering even more staff layoffs and providing less resources for wildlife conservation, which are pivotal to recovering America's imperiled species," Westfall warned. "Our nation's lands and the wildlife that depend on them for habitat deserve better than to be ignored by agencies that are shells of their former selves."
The president's proposed attack on endangered species came just days after the administration's so-called "God Squad" voted unanimously for an exemption allowing fossil fuel operations in the Gulf of Mexico to ignore policies intended to protect them. In response, Andrew Bowman, president and CEO of Defenders of Wildlife, said that "I cannot stress enough how unprecedented and unlawful this action is."

Robert F. Kennedy Jr. Is Making America Sick Again
Three recent stories about measles have implications that are far more consequential for the fate of humanity than Trump’s racist memes or his destabilizing antics on the world stage.
Feb 19, 2026
Not until President Donald Trump is long gone will Americans feel the full impact of his most destructive policies and his administration’s incompetence. Today’s topic: Measles.
“For children, the risks of measles are especially grave. Complications, which occur in 1 in 5 people who have the disease, can include pneumonia, blindness, permanent neurologic injury, and death. These outcomes are well-documented, particularly among young children and those with delayed access to medical care.” (Theresa Cheng, MD, JD, assistant clinical professor in the Department of Emergency Medicine at UCSF-Zuckerberg San Francisco General Hospital and a lawyer.)
Measles is preventable, but community immunity requires a 92-94% vaccination rate. Since the introduction of the measles vaccine in 1963, the incidence of the disease has decreased by over 99%, thanks to the combination of immunity through prior exposure and vaccination rates above the required threshold.
Secretary of Health and Human Services Secretary Robert F. Kennedy Jr. is reversing that remarkable public health achievement.
Someone who does not get vaccinated puts others—mostly children who have no voice in the critical decision to protect or jeopardize their health—at serious risk of injury or death.
Three recent stories about measles have implications that are far more consequential for the fate of humanity than Trump’s racist memes or his destabilizing antics on the world stage.
Story No. 1: Measles Outbreak in South Carolina
Between 1991 and 2024, South Carolina had a total of only 8 measles cases—6 of which occurred within a single household in 2018.
In October 2025, the state reported the first three cases in the current outbreak.
As of February 17, South Carolina had 962 confirmed measles cases; 253 involve children under 5, 615 are ages 5 to 17, 85 are adults, and nine ages are unknown.
Since the outbreak, 20 individuals have been hospitalized with complications related to the disease.
Ninety-five percent of the infected individuals were not vaccinated.
The area of the state experiencing the greatest number of cases (95% of them) also led the state in the decline in vaccination rate: Spartanburg County’s rate dropped from 93.9% in 2021-2022 to 88.9% the current school year—well below the critical threshold required for community immunity.
Story No. 2: Anti-Vaxxers Determine America’s Public Health Policy
Kennedy has gutted the Department of Health and Human Services. He has replaced scientific and medical experts with hacks who adhere here to his willful ignorance.
One of those appointees is the leader of the federal panel that recommends vaccines for Americans, Dr. Kirk Milhorn, chair of the Advisory Committee on Immunization Practices. On January 22, Milhorn said that vaccines protecting children from polio and measles, and perhaps all diseases, should be optional.
“What we are doing is returning individual autonomy to the first order—not public health but individual autonomy to the first order.”
What he and his colleagues are actually doing is killing us. Kennedy has already dropped six vaccines from the childhood immunization schedule.
Story No. 3: States Are the Last Line of Defense
Only individual states, which have ultimate responsibility for vaccine schedules, have saved the country from the full destructive force of Kennedy’s anti-science, anti-vaxxer crusade. But his ascension as head of the nation’s federal public health policy has empowered his allies to target state childhood vaccination mandates.
The Medical Freedom Act Coalition includes the Children’s Health Defense—a nonprofit group that Kennedy co-founded. It is pushing legislation that would end state laws that codify vaccination schedules. Such legislation is pending in several states.
Asked about the effort, Kennedy said he was not involved, but added, “I believe in freedom of choice.”
As the impact of his attack on science intensifies, the overall public health costs will be staggering.
Earlier this month, Chris Anders, a Republican state lawmaker in West Virginia, introduced a bill that would eliminate his state’s school vaccination mandates, including the requirement that county health departments offer free shots to low-income children.
“If people decide not to be vaccinated, that is their choice,” he argued. “Just like if they decide not to wear a seatbelt or a motorcycle helmet or anything else. If they decide that, they suffer the consequences.”
Kennedy, Milhorn, Anders, and their like-minded anti-vaxxers march under the “freedom of choice” banner. It’s a red herring that omits a crucial element of the equation: Someone who does not get vaccinated puts others—mostly children who have no voice in the critical decision to protect or jeopardize their health—at serious risk of injury or death.
For a long time to come, everyone else’s kids will bear those consequences.
Epilogue: Ripple Effects
The measles vaccine is the small tip of an enormous public health iceberg. Kennedy and his anti-vaxxers in charge of public health have “sent a chill through the entire [vaccine] industry,” according to Dr. John Coller of Johns Hopkins University, a member of the executive committee of the Alliance for mRNA Medicines.
As Kennedy creates unwarranted fears about the safety and efficacy of lifesaving vaccines, some Americans will continue to believe him and vaccine sales will suffer. As he cuts research funding for new vaccine development, America will be unprepared for the next pandemic. As the impact of his attack on science intensifies, the overall public health costs will be staggering.
Future historians will scratch their heads in disbelief at what we are doing to ourselves and our children.
