The Cost of Assimilation: Why Diversity Matters

by Brett Hayhoe | May 2026

Introduction

There is a story many nations tell themselves about how to build a cohesive society. It goes like this: if everyone looks the same, speaks the same language, shares the same customs, and forgets where they came from, then unity will follow naturally. It is a tidy story. It is also, the evidence increasingly suggests, wrong.

The demand for assimilation — that newcomers and minorities erase their distinctiveness in order to belong — has been tried repeatedly across the world, in colonial settlements, in post-war immigration programs, in Indigenous policy, and in nationalist movements of every political stripe. The results have not been unity. They have been resentment, cultural grief, social fracture, and — at the extremes — violence. True cohesion, it turns out, is not built by flattening difference. It is built by honouring it, within a framework of shared values that nobody had to give up their identity to join.

The Difference Between Unity and Uniformity

Unity and uniformity are not the same thing, though they are constantly confused. Uniformity demands sameness. Unity requires only that people are willing to share a common life — to live under the same laws, to care about one another’s wellbeing, to show up for each other when it matters. One of these things is achievable in diverse societies. The other is not, and the attempt to impose it causes enormous harm along the way.

The philosopher Charles Taylor called this the “politics of recognition” — the idea that human dignity is partly constituted by having one’s identity acknowledged rather than suppressed. When a society tells a person: you are welcome here, but only if you stop being who you are — it does not create belonging. It creates a choice between survival and self-erasure. Many people choose survival. But the cost is carried quietly for generations, in lost languages, broken family bonds, severed cultural memory, and a persistent sense of not quite fitting anywhere.

Australia knows this story with particular intimacy. The Stolen Generations policy — which removed Aboriginal and Torres Strait Islander children from their families in an explicit attempt to assimilate them into white society — did not produce unity. It produced trauma so deep it still shapes health outcomes, incarceration rates, and family structures today. The lesson could not be starker: assimilation enforced at the cost of community does not build nations. It wounds them.

What Community Actually Does

Community is not sentiment. It is infrastructure. Tight-knit communities — whether defined by ethnicity, religion, neighbourhood, or shared experience — perform functions that governments cannot easily replicate. They provide mutual aid in hard times. They transmit values and cultural knowledge across generations. They offer identity anchors that allow individuals to engage with a broader society from a position of security rather than anxiety.

Research in social psychology consistently finds that people with strong community belonging are more likely — not less — to engage positively with people outside their group. The mechanism is counterintuitive to assimilationist thinking but makes psychological sense: security enables openness. When people feel their identity is safe, they are less defensive, less tribal, less threatened by difference. It is insecurity — the experience of being constantly asked to prove you belong, of having your culture treated as an embarrassment — that breeds the inward-looking tribalism that critics of multiculturalism most fear.

This is why the most successful multicultural societies are not those that demanded cultural surrender, but those that created conditions in which different communities could thrive alongside each other — connected by shared civic values, equal rights, and genuine mutual respect.

Solidarity Is Not Sameness

The progressive tradition has long understood solidarity as a force that crosses difference rather than erases it. Trade union movements brought together workers of wildly different backgrounds — Irish and Italian immigrants, Indigenous workers, women entering the workforce — not by making them identical, but by giving them a common cause and a shared stake in each other’s outcomes. The most durable solidarity movements in history have been pluralist at their core.

The contemporary challenge is to extend this logic beyond the workplace. Solidarity in a diverse society means that the wellbeing of a Somali refugee family in suburban Melbourne is understood as connected to the wellbeing of a fourth-generation Anglo-Australian farmer in regional Queensland — not because they are the same, but because they share a common life and a common future. That connection cannot be mandated. It has to be cultivated, through institutions, through storytelling, through the slow work of actually knowing each other.

This is the work that assimilationist thinking short-circuits. If the price of belonging is invisibility, many communities will — quite rationally — withdraw from the broader society rather than pay it. The result is not the integration that assimilationists claim to want. It is parallel lives, mutual suspicion, and the very fragmentation they feared.

When the Pressure to Assimilate Is Personal: LGBTIQA+ Communities

Nowhere is the violence of assimilationist thinking more viscerally clear than in the lives of LGBTIQA+ people around the world. The demand placed on queer and gender-diverse people has historically not been “fit in differently” — it has been “disappear entirely.” Conversion practices, criminalisation of same-sex relationships, the enforced performance of heterosexuality in family and workplace settings, the erasure of transgender identities from law and medicine: these are assimilation demands in their most intimate and devastating form. They do not ask people to set aside a cultural practice or adopt a new language. They ask people to deny the most fundamental aspects of who they are.

The consequences are well documented. LGBTIQA+ people who lack access to affirming community — who are isolated from others who share their experience, who have no safe spaces in which their identity is treated as ordinary and worthy — face dramatically elevated rates of depression, anxiety, suicidality, and social disconnection. The research is unambiguous on this point: LGBTIQA+ community belonging is not a luxury or a lifestyle preference. It is a protective health factor. Queer spaces — the community centre, the social group, the affirming congregation, the online forum for a young person in a rural town — perform exactly the function that all communities perform: they provide the security from which a person can engage with the broader world on their own terms, rather than on terms that require their self-erasure.

This matters globally because the pressure to assimilate — to simply “not make it an issue,” to be quietly tolerated rather than genuinely included — remains intense across most of the world, and is actively intensifying in some places. In over sixty countries, same-sex relationships remain criminalised. In many others, legal recognition exists on paper while social and family pressure to conform operates at full force beneath it. Even in relatively progressive societies, LGBTIQA+ people — particularly those who are also racialised minorities, disabled, or from conservative religious backgrounds — often face a double bind: assimilate into the mainstream, or assimilate into a queer community that may not fully reflect their whole identity either. The answer, in both cases, is the same: more community, not less. More spaces of genuine recognition. More solidarity that holds difference without demanding its resolution.

Summary

The choice societies face is not between unity and diversity. It is between two different theories of how unity is achieved. One theory demands conformity — strip away difference, demand a single identity, and hope the friction disappears. History has tested this theory exhaustively, and the verdict is in: it doesn’t work. It produces not unity but rupture, not belonging but exile, not solidarity but the long, slow burn of communal grief.

The other theory is harder and more honest. It says: equality does not require sameness. Solidarity does not require uniformity. Community — real community, grounded in place and culture and mutual recognition — is not a threat to a cohesive society. It is the very foundation one is built on. When people are secure in who they are, they can afford to be generous with who you are. That generosity is what a good society is made of.

The lucky societies will be those that learn this in time — that resist the seductive simplicity of “just assimilate” and do the harder, richer, more rewarding work of building unity across genuine difference.

❓ Frequently Asked Questions

Q: What is the difference between integration and assimilation?
A: Integration means joining a broader society while retaining your cultural identity — adopting shared civic values and participating in public life without erasing who you are. Assimilation typically demands that newcomers or minorities abandon their distinct culture, language, or practices in order to be accepted. Integration tends to produce healthier social outcomes than assimilation.

Q: Doesn’t a common language and culture help societies function better together?
A: Shared civic tools — a common language for public life, shared legal norms, mutual civic duties — are genuinely valuable and compatible with cultural diversity. The problem arises when “common culture” is used to mean that minority cultures must disappear entirely. Bilingualism, for example, is not a barrier to social cohesion; research consistently shows it is an asset.

Q: Isn’t there a risk that strong ethnic communities become isolated and insular?
A: This is a legitimate concern, but the evidence suggests that insularity is more often a response to exclusion than a product of cultural pride. Communities that feel their identity is respected and their members treated as equal citizens tend to be more outward-looking, not less. The solution to insularity is inclusion, not forced erasure.

Q: What does this mean for immigration policy?
A: It suggests that successful immigration policy focuses on equality of rights, access to language learning and economic opportunity, anti-discrimination enforcement, and civic participation — not on demanding cultural surrender as the price of belonging. Countries like Canada and New Zealand have tested multicultural frameworks with broadly positive results.

Q: How does this apply to Australia’s First Nations communities?
A: Perhaps more urgently than anywhere else. Decades of assimilationist policy — including the Stolen Generations — caused profound, multigenerational harm. Genuine reconciliation requires recognising First Nations cultures as living, legitimate, and deserving of support — not as remnants to be absorbed into mainstream Australia. Self-determination, not assimilation, is the framework most consistently supported by First Nations peoples themselves.

Q: Can equality and community coexist? Don’t group identities create hierarchies?
A: Equality means equal dignity and rights for all individuals — it does not require that all cultural expressions be identical. A commitment to equality actually demands that we protect the conditions in which diverse communities can flourish, because suppressing cultural identity is itself a form of inequality. Solidarity is what ties individual equality to collective wellbeing.

Q: What is the “politics of recognition” and why does it matter?
A: The term, developed by philosopher Charles Taylor, refers to the idea that human identity is partly formed through recognition by others. When societies refuse to recognise — or actively suppress — a person’s cultural identity, they do a form of harm that goes beyond material disadvantage. It matters because no amount of economic inclusion fully compensates for the experience of being asked to be ashamed of who you are.

Q: Why is community belonging particularly important for LGBTIQA+ people?
A: Because the alternative — isolation from affirming community — carries serious, measurable health consequences. Research consistently shows that LGBTIQA+ people with access to community support have significantly better mental health outcomes than those without it. Queer community is not a social extra; it is a survival structure for many people, particularly young people, those in conservative family environments, and those in countries where their identity is criminalised or stigmatised.

Q: Doesn’t encouraging distinct LGBTIQA+ community spaces create more division, not less?
A: No — and this is a crucial misunderstanding. Safe, affirming community spaces allow LGBTIQA+ people to develop a secure sense of identity from which they can participate fully in broader society. The evidence shows that people who feel secure in their identity are more — not less — able to build relationships across difference. Demanding that queer people simply “blend in” doesn’t produce integration; it produces hiding, and hiding is not the same as belonging.
