There is a remarkably reliable finding in psychology that almost everyone has encountered in some form: people get used to good things. Lottery winners return to baseline happiness within months. Homeowners stop noticing the view. The promotion, the car, the relationship — the initial surge of pleasure fades and what remains is a new normal, invisible precisely because it has become ordinary. This is hedonic adaptation, one of the most replicated phenomena in behavioural science, and it has been confirmed across hundreds of studies, tens of thousands of participants, and nearly every domain of positive human experience.

Patriotism should follow this curve. If what patriots feel is appreciation — love of country, gratitude for home — then the prediction is straightforward. An immigrant arrives and feels a rush of relief and belonging. Five years in, it has become comfortable. By year thirty, it is wallpaper. Native-born citizens, who have never known anything else, should feel even less. The country is their baseline. There is nothing to contrast it with.

This is not what happens. The most fervent patriots are often lifelong residents who have never left. Their intensity does not fade with exposure — it deepens. They perform constantly: flags on porches, hands on hearts, arguments online about national greatness that grow sharper with age, not softer. Year thirty-five looks nothing like habituation. It looks like escalation.

That pattern does not match appreciation. It matches something else entirely.

The curve that doesn’t fit

Brickman and Campbell’s foundational work on the hedonic treadmill, refined by Diener, Lucas, and Scollon in 2006 and confirmed by Luhmann’s 2012 meta-analysis of 188 publications, establishes a clear architecture: people adapt to positive changes and return toward baseline. Marriage produces an initial boost that declines. Childbirth follows the same curve. Income gains lose their hedonic impact — after four years, only about 42 percent of the original effect remains. The machinery is consistent. Good things become normal things. Normal things stop registering.

Negative stimuli follow a different curve. Unemployment has persistent effects that resist adaptation even years later. Disability produces drops in happiness from which recovery is partial at best. Fear conditioning, as Sotres-Bayon and Quirk documented, creates associations that are learned fast and persist — while safety learning is slow and fragile. Extinguished fear returns spontaneously with time, reappears when the context shifts, and reinstates at the slightest provocation. The asymmetry is structural: the brain is built to let go of pleasure and hold onto threat.

The question, then, is which curve patriotism follows. If it is love, it should habituate. If it is fear, it should persist and intensify. The behavioural evidence is not ambiguous.

Patriotism tracks threat, not enjoyment

Gallup has measured American pride continuously since 2001. The data tell a specific story. In 2001, before September 11th, 55 percent of Americans described themselves as “extremely proud” to be American. By 2003, at the launch of the Iraq War, this figure hit 70 percent — the all-time peak. It has declined almost continuously since, reaching 38 percent in 2022 during a period of relative peace and economic stability, and 41 percent in 2025.

The pattern is precise. Pride surges during wars and crises. It recedes during calm. The late 2010s saw record-low unemployment and strong GDP growth — and record-low patriotism. The post-9/11 period saw economic uncertainty and existential fear — and the highest patriotic intensity ever measured. George W. Bush’s approval rating jumped 39 points in a single week after September 11th. Carter gained 23 points when the hostages were taken in Iran. Putin gained 14 points after annexing Crimea.

No comparable surge has ever followed a national achievement. Not the moon landing, not an economic boom, not a major piece of legislation. The rally-around-the-flag effect is among the most documented phenomena in political science, and it activates exclusively through threat. The flag becomes more important precisely when things feel endangered. That is not how people respond to something they appreciate. It is how they respond to something they are afraid of losing.

The neurology of not letting go

The biological architecture beneath this is well-mapped. Baumeister’s landmark 2001 review — over ten thousand citations — established that bad is stronger than good across virtually every psychological domain. Bad emotions form faster. Bad impressions resist disconfirmation more stubbornly. Bad feedback is processed more thoroughly. The self is more motivated to avoid negative definitions than to pursue positive ones. The asymmetry is not cultural. It is architectural.

The amygdala processes threat through a subcortical fast-path that operates before conscious awareness — LeDoux’s “low road.” Fear associations form in a single trial. Extinction requires extensive retraining and produces a fragile memory that competes with the original fear rather than erasing it. Nesse’s smoke detector principle explains why: if a false alarm costs 100 calories but a missed predator costs 100,000, then a system calibrated to over-respond is the one natural selection keeps. Nine hundred and ninety-nine false alarms out of a thousand is not a malfunction. It is the optimal design for an organism whose survival depends on never missing a threat.

Patriotic behaviour fits this architecture with uncomfortable precision. The flag displays, the anthem reverence, the online vigilance about who is and is not showing sufficient respect — these are not the behaviours of someone enjoying something. They are the behaviours of someone guarding something. Enjoyment is passive. It habituates. It does not need to be performed. Vigilance is active, persistent, and escalates under stress. The distinction is not subtle.

What the immigration data reveal

The Cato Institute’s 2019 analysis of General Social Survey data found that naturalised immigrants report higher pride in America than native-born citizens — 75 percent “very proud” compared to 69 percent. They express greater confidence in all three branches of government. They are less likely to report shame about their country.

The hedonic adaptation model predicts this cleanly. Immigrants have a contrast point. They arrived from somewhere worse, experienced the difference viscerally, and the contrast has not fully faded. Native-born citizens have no contrast. They habituated before they had language to describe the process.

But notice who gets called patriotic. An immigrant who says “yeah, it’s nice here, the hospitals work” — casual, habituated, the authentic sound of someone who has settled into appreciation — is rarely described as a patriot. An immigrant who declares “this is the GREATEST country on EARTH” with visible intensity is. The social category rewards the anxious performance and ignores the calm contentment. The label itself is diagnostic. It selects for fear-coded behaviour and filters out appreciation-coded behaviour, which tells you what the category is actually tracking.

The concession that strengthens the case

There is a genuine counterargument here, and it deserves precise engagement. Schatz, Staub, and Lavine’s 1999 work on blind versus constructive patriotism identified two empirically separable forms of national attachment. Constructive patriotism — critical, engaged, tolerant of dissent — correlates with political knowledge, efficacy, and openness. Blind patriotism — unquestioning, performative, intolerant of criticism — correlates with perceptions of foreign threat, nationalism, and political disengagement. Orwell drew a similar line in 1945: patriotism as quiet love of place, nationalism as power-hunger tempered by self-deception.

This distinction is real and the data supporting it are robust. Livi’s 2018 latent profile analysis of nearly 14,000 New Zealanders found a “pure patriot” group — high attachment, low nationalism — that showed the most positive attitudes toward immigrants of any group in the study. These people exist. Their attachment to their country does not appear to operate through fear.

The concession does not rescue patriotism as a category. It refines the diagnosis. What Schatz calls constructive patriotism looks, behaviourally, exactly like habituated appreciation — calm, non-performative, comfortable with criticism because the attachment is secure enough not to require defence. It follows the hedonic curve. It is also, notably, not what anyone means when they talk about patriotism in the political arena. No politician has ever rallied a crowd by saying “I appreciate this country at a moderate, habituated level and I am comfortable with its imperfections.” The patriotism that moves elections, fills stadiums, starts wars, and sells bumper stickers is the other kind. The loud kind. The kind that does not habituate.

Loss aversion in a flag

Kahneman and Tversky’s prospect theory provides the final structural piece. Losses are felt approximately twice as intensely as equivalent gains — a ratio confirmed across 607 empirical estimates in Brown’s 2024 meta-analysis. The brain regions activated by losses overlap significantly with the amygdala and posterior insula — threat-processing architecture, not reward architecture. Loss aversion is not a cognitive bias in the trivial sense. It is a deep feature of how the nervous system weights experience.

Nationalist rhetoric operates almost exclusively in the loss frame. “Make America Great Again” is a loss-aversion statement — the greatness existed, it was taken, it must be recovered. “Take Back Control.” “Our culture is being destroyed.” “We’re losing our way of life.” Elgenius and Rydgren’s 2022 analysis found that the hallmark of nationalist nostalgia is the conviction that the past was superior to the present — a framing that converts the current moment into a continuous loss, experienced with the amplified intensity that prospect theory predicts. The emotional engine is not positive valuation of what exists. It is aversion to its disappearance.

Cohen’s 2004 study found that reminding people of their own mortality produced an 800 percent increase in support for charismatic leaders. Burke’s 2013 meta-analysis found a large overall effect (r = .50) of mortality salience on political conservatism and worldview defence. When people are reminded they will die, they grip harder on their cultural identity, their national symbols, their in-group. This is not appreciation deepening. It is fear radiating outward into whatever structures promise permanence.

The tell

Pew’s 2026 cross-national survey found that levels of national pride are higher in countries whose citizens are worse off. The correlation runs the wrong direction for appreciation and the right direction for anxiety. People in precarious circumstances grip harder on identity constructs — not because those constructs have become more enjoyable, but because the need for psychological security has intensified.

Generational data show the same gradient from a different angle. Gallup’s 2021-2025 averages: the Silent Generation reports 83 percent extreme or very proud. Baby Boomers, 75 percent. Gen X, 71. Millennials, 58. Gen Z, 41. The standard interpretation is that younger generations are less patriotic. The adaptation-asymmetry interpretation is different: older generations have accumulated more to lose. Their identity architecture is more invested in the national construct. The threat of its dissolution is more personally destabilising. Their patriotism has not deepened through appreciation. It has calcified through loss aversion.

The people who genuinely enjoy where they live — the food, the landscape, the neighbours, the particular quality of light in the evening — tend to express it the way people express any habituated pleasure. Casually. Without performance. Without needing anyone else to affirm it. They do not argue about it online. They do not feel threatened when someone criticises their country. They have adapted, as the model predicts, and what remains is the comfortable background contentment of someone who has settled into something good.

The people who cannot stop performing their love of country, who escalate rather than habituate, who respond to criticism as though it were an attack — they are not appreciating more intensely. They are defending more desperately. The behaviour is identical to every other threat response the psychological literature has mapped: persistent, resistant to extinction, amplified by mortality salience, and activated not by the presence of something good but by the possibility of its loss.

If your patriotism is calm and you have never felt the need to announce it, this essay is not about you. You have habituated. You are enjoying your country the way people enjoy anything they have lived with long enough — quietly, securely, without performance.

If your patriotism is loud, and getting louder — the hedonic treadmill has a diagnosis for you, and it is not love.
