The oldest and most-quoted answer is that being American has nothing to do with ancestry, race, or birthplace, and everything to do with believing in a set of ideas: liberty, equality, self-government, and the consent of the governed. On this view, America is the one nation on earth founded not around a shared bloodline or a shared church, but around a shared sentence — "all men are created equal" — that anyone, anywhere, can affirm and join.
The case for it: It's radically inclusive. A refugee sworn in yesterday has, in principle, exactly as much claim to being American as someone whose ancestors arrived on the Mayflower. Identity becomes a choice, not an accident of birth.
The case against it: Critics ask whether a nation can really hold together on abstractions alone. Ideas are thin glue compared to language, land, or shared ancestry — and a country that defines itself only by a creed can fracture the moment people disagree about what the creed actually requires (which, in America, is constantly).
A close cousin of the creed: being American means belonging to a nation built by people who left somewhere else — often at great risk — to come here. On this telling, the defining American trait isn't a belief system but an act: the decision to leave the known for the unknown in search of something better.
The case for it: It captures something real about national temperament — restlessness, risk tolerance, reinvention. Immigrants self-select for ambition, and each new wave has re-energized the country economically and culturally.
The case against it: It quietly writes two large groups out of the story. Indigenous peoples were here before there was an "elsewhere" to leave. And millions of Black Americans arrived not by choice but in chains — their American story beginning in violence, not aspiration. "Nation of immigrants" is true, but it isn't the whole nation.
Military service, jury duty, voting, paying taxes, running for the school board — on this view, being American isn't a feeling or a belief, but a set of obligations fulfilled. Citizenship is a contract, and the "American" part is holding up your end.
The case for it: It ties rights to responsibilities and gives citizens tangible stakes in a shared project, rather than treating national belonging as a passive inheritance.
The case against it: Defining American-ness by service risks quietly demoting those who, for reasons of disability, age, or circumstance, cannot serve in the same visible ways — implying a hierarchy of "real" versus lesser citizens that the country's founding documents never actually endorse.
Popularized most notably by political scientist Samuel Huntington, this view holds that America has a specific cultural core — the English language, English common law, Protestant work ethic, and dissenting religious tradition — into which later arrivals assimilate. On this account, America isn't culturally neutral; it has a distinct inherited character that immigrants join rather than replace.
The case for it: It offers a concrete explanation for why American institutions — courts, contracts, town meetings, a free press — look the way they do, and why they've proven durable across two and a half centuries.
The case against it: Taken too far, it slides into a gatekeeping nativism that treats later, non-Protestant, non-English-speaking arrivals as guests rather than owners. It also understates how much the "core" itself has already been remade by Catholic, Jewish, Muslim, and secular Americans who are unmistakably part of the culture now, not merely absorbed into someone else's.
Self-reliance, personal responsibility, a suspicion of dependency on others or on government — the frontier homesteader and the garage-startup founder are cut from the same cultural cloth. On this view, being American means believing that you, and largely you alone, are responsible for your own fate.
The case for it: It's a genuine engine of innovation and resilience. A culture that rewards risk-taking and self-invention produces disproportionate entrepreneurship, mobility, and grit.
The case against it: No one is actually self-made. Roads, schools, courts, the electrical grid, publicly funded research — the "self-reliant" success story usually rests on a mountain of collective investment its beneficiaries rarely acknowledge. Taken to an extreme, individualism can become a justification for abandoning the sick, the poor, and the unlucky.
The promise that anyone, regardless of where they started, can rise as far as their talent and effort will carry them. It's the most exported American idea in the world — the belief that origin is not destiny.
The case for it: It's a genuinely unifying aspiration across an otherwise divided country, and there is real evidence of mobility: waves of immigrants and their children have climbed economically within a generation or two.
The case against it: Economic mobility in America has stagnated for decades, and research consistently shows a child's zip code and parents' income still predict their outcomes more than the myth admits. Worse, the Dream can function as an alibi — implying that anyone who doesn't rise simply didn't try hard enough, obscuring the structural barriers in the way.
Two competing metaphors for the same question: does becoming American mean blending into one shared culture, or does America mean many distinct cultures coexisting, unmelted, side by side?
The case for the melting pot: A common culture, language, and set of civic habits create social trust and cohesion — the glue that lets strangers from wildly different backgrounds function as one nation.
The case for the salad bowl: Pluralism preserves what makes each community's heritage valuable rather than erasing it. A Chinatown, a Little Havana, a Cajun parish — these aren't failures to assimilate; they're part of what makes American culture richer than any single ingredient.
The tension: Forced assimilation has an ugly history — boarding schools that stripped Native children of language and culture, immigrants pressured to Anglicize their names. But pure, unmelted pluralism risks a country of parallel communities with no shared floor to stand on.
On this view, what makes someone American isn't culture, ancestry, or even belief — it's living under, and being accountable to, a shared constitutional order. The Constitution, not any people or culture, is the actual unifying object.
The case for it: It offers real, durable protection against tyranny and mob rule, and it means the nation can absorb enormous cultural change without its fundamental structure breaking — the same document has weathered a civil war, mass immigration, and civil rights revolutions.
The case against it: Law is not automatically justice. For most of American history, the "rule of law" was the law that upheld slavery, then Jim Crow, then Japanese internment. Pointing to the Constitution as the unifying American identity says nothing about whether the law being followed at any given moment is actually good.
Sociologists have long noted that America has something like a secular faith — reverence for the flag, the founding documents, Lincoln's memorial, the National Anthem before every ballgame — that functions the way shared religion does in other nations.
The case for it: It gives a religiously and ethnically fragmented population shared rituals and symbols to rally around — something to be reverent about together, even amid deep disagreement.
The case against it: Civil religion can calcify into empty nationalism — reverence for symbols standing in for actual engagement with what those symbols are supposed to represent.
Restlessness, expansion, the pull toward the unmapped horizon — historian Frederick Jackson Turner argued that the frontier shaped the American character: practical, improvisational, always pushing west.
The case for it: It's a plausible account of a genuinely distinct national temperament — optimistic, self-reinventing, comfortable with risk and reinvention in a way older, more settled cultures often aren't.
The case against it: The frontier wasn't empty. "Expansion" meant the displacement, and often the deliberate destruction, of Native nations who were already there. A romantic story about taming the wilderness is, from another vantage point, a story about conquest — and any account of the American character has to hold both at once.
The belief, dating to the Puritans' "city on a hill" and running through Cold War rhetoric to today, that the United States has a unique moral role in the world — not just a country among countries, but a model, or even a mission.
The case for it: It has genuinely inspired sacrifice — from Lend-Lease to the Marshall Plan to decades of alliance-building — and it gives Americans a demanding standard to be held to, not just a flattering one.
The case against it: "We're the good guys" reasoning has also been used to excuse a great deal — interventions, coups, and double standards that a less self-mythologizing country might have scrutinized more closely. Exceptionalism cuts both ways: it can be a call to live up to ideals, or a license to assume you already have.
From the Boston Tea Party to the civil rights marches to protests on courthouse steps today, a persistent American tradition holds that the truest patriots are often the loudest critics — that a country founded by revolutionaries has no business treating criticism of its government as disloyalty.
The case for it: It's baked into the founding logic itself — the Revolution was an act of dissent — and it gives the country a self-correcting mechanism that more rigid nations lack. The right to protest is a release valve, not a threat, to a healthy republic.
The case against it: "Dissent is patriotic" can become a rhetorical blank check, deployed to justify nearly any behavior, from peaceful protest to political violence, under the same banner. If the label stretches to cover everything, it risks meaning nothing.
For much of the 20th century, especially, "American" and "capitalist" were spoken almost as synonyms — private property, competition, and entrepreneurship framed not just as an economic system but as a national value in itself.
The case for it: It's hard to argue with the results: American markets have produced extraordinary innovation, wealth, and living standards, and economic freedom has often traveled hand in hand with personal freedom.
The case against it: This conflates a specific, contested economic policy with national character, as though skepticism of unregulated markets were somehow un-American. Plenty of the country's founders, and plenty of citizens since, have argued for a much more regulated, mixed economy — and they were no less American for it.
Rather than one national culture, this view holds that America is really fifty (plus) separate experiments in self-government, each free to reflect very different values — identity rooted less in "America" as a monolith than in one's state, county, or town.
The case for it: It allows enormous internal diversity of governance to coexist without constant, exhausting national conflict over every issue — Vermont and Texas don't have to agree on everything to both be fully American.
The case against it: Federalism can entrench real inequality — meaning your rights, protections, or opportunities depend heavily on which state line you happen to live behind, a version of "American-ness" that varies by zip code more than most people are comfortable admitting.
Under the Fourteenth Amendment, anyone born on American soil is a citizen, full stop — regardless of their parents' immigration status, nationality, or how long the family has been here. It's one of the most literal, legally mechanical definitions of American-ness on this list: not a belief, not a culture, not an act of will, just a fact of geography at the moment of birth.
The case for it: It's clean and radically inclusive, avoiding the creation of a multi-generational underclass of people born in the country but permanently excluded from full membership in it — a problem several other nations with ancestry-based citizenship (jus sanguinis) still wrestle with. It also reflects a distinctly American discomfort with hereditary distinctions of any kind, born from a founding generation that rejected inherited titles and status.
The case against it: It's currently one of the most contested provisions in American law and politics, with critics arguing that citizenship should be tied more to parental allegiance or legal status than to the accident of where a birth happens to occur. Others counter that this is precisely the kind of blood-and-soil thinking the amendment was written to foreclose. Unlike most items on this list, this isn't just a philosophical disagreement — it's an active legal and political fight over what the text actually requires.
To much of the world, "American" isn't primarily a legal status or a philosophical creed — it's blue jeans, Hollywood, hip-hop, fast food, Silicon Valley apps, and the English of the internet. On this view, American identity is best measured not by what the Constitution says but by what the rest of the planet actually consumes, imitates, and recognizes instantly, from Lagos to Seoul.
The case for it: It's real, lived influence, not just rhetoric — American culture has shaped global tastes, aspirations, and even slang more thoroughly than any empire managed through force. It's also oddly democratic: you don't need to immigrate, take an oath, or study the Federalist Papers to have a relationship with American identity — you can just watch the movie or stream the song.
The case against it: This reduces a two-and-a-half-century political project to a set of consumer products. Conflating "what sells globally" with "what America actually values" flattens the argument-and-ideals version of American identity into something closer to a brand — and brands, unlike constitutions, don't require anyone to live up to anything.
Perhaps the most demanding answer: that being American means living inside the permanent, unresolved gap between the country's stated ideals — "all men are created equal" — and its actual historical practice — slavery, segregation, the denial of the vote to women and Black Americans, the removal of Native nations. On this view, American identity isn't the ideals or the failures alone, but the ongoing struggle to close the distance between them.
The case for it: It's honest, and it's actually optimistic in a hard-won way — it frames abolition, suffrage, and civil rights not as betrayals of the founding but as fulfillments of it, evidence that the country can be pried open toward its own stated promises.
The case against it: Some feel this framing is too critical for a celebration — that a 250th birthday should emphasize achievement, not unfinished business. Others argue the opposite: that ignoring the gap, especially on an anniversary, is its own kind of dishonesty, and that the closing of that gap is the actual achievement worth celebrating.
