The E–I–σ Framework
A Diagnostic Model for Understanding the Social Mechanics of
Immigration
R.M. Westerink; August 2026
Immigration Concern Is Not a Diagnosis
Suppose a government learns that a majority
of voters think immigration is too high.
What has it actually learned?
Less than it may appear.
Some people may be worried about housing.
Others may be worried about pressure on schools or healthcare.
Some may think government has lost control of immigration.
Others may be uncomfortable with unfamiliar customs or rapid cultural change.
Some may fear crime or insecurity.
Some may hold strongly negative views of foreigners.
And others may like the immigrants they know perfectly well while still
believing that the country is adding population too quickly.
Politically, all these reactions can
accumulate into the same headline: “Concern about immigration is rising.”
Socially, they are not the same problem.
E–I–σ helps us find out
what the immigration problem actually is.
Because different
immigration problems require different responses.
A housing shortage is not solved by telling
people to be more tolerant.
Intergroup unfamiliarity is not solved by building more houses.
Better communication cannot compensate indefinitely for an immigration system
that is visibly overloaded.
And reducing immigration numbers does not necessarily remove established
hostility toward foreigners.
Before choosing a remedy, we therefore need
to know what is producing the concern.
This is the purpose of the E–I–σ ("Eee Eye Ess") Framework.
Three Elements to Look At
E–I–σ
begins with three simple questions.
|
E
— Existing society
|
What kind of society is receiving the
change?
|
|
I
— Incoming group
|
What is changing —
who is arriving, how many, how quickly, and where?
|
|
σ
— Circumstances
|
What else is happening —
housing, jobs, services, politics, media, security, trust in government?
|
None of this is difficult to recognize. The
added value comes from looking at the three together.
The mechanisms themselves are familiar to
social science: research on intergroup anxiety, social identity, perceived
threat, intergroup contact and group competition has examined different parts
of them for decades. E–I–σ brings
these strands together as a diagnostic model of immigration-related social
change.
Imagine:
A country with a long
immigration history and generally positive attitudes toward immigrants.
Housing, however, has become seriously scarce. At the same time, Immigration rises
rapidly while public confidence in government's ability to manage population
growth falls.
An opinion poll may
record the result simply as greater opposition to immigration.
E–I–σ
opens that result up. The existing society is
relatively familiar with immigration. The incoming change is unusually rapid.
The surrounding circumstances include housing scarcity and declining confidence
in management. The concern that emerges may therefore be less “we dislike
immigrants” than “we are adding people faster than we can house them.”
That is a different diagnosis — and it
points toward different questions and different policy options.
The E–I–σ model does not re-interpret the facts.
It makes their relationships — and therefore the diagnosis — visible.
A First Distinction: Unfamiliarity Is Not Xenophobia
Some immigration-related reactions begin at
a much more personal level.
Most people find interaction easier when
they understand the unwritten rules. We know what counts as polite, understand
the language, recognize humor and can roughly predict how another person will
respond.
When those rules are unfamiliar, some
uncertainty or discomfort can arise. Social psychology calls this intergroup
anxiety (see also Stephan & Stephan).
It can occur on either side of an
encounter. A recently arrived refugee entering an unfamiliar European workplace
can experience it. So can an established resident meeting his neighbors whose
language and customs are unfamiliar.
Often intergroup anxiety diminishes
over time. People learn how to communicate, become colleagues, become club members,
become involved in a large variety of social contacts. What was unfamiliar
becomes ordinary.
This matters because intergroup anxiety
is not the same as xenophobia.
|
A
person says…
|
The
first diagnostic question is…
|
|
“I don't know how to communicate with
these people.”
|
Is unfamiliarity producing intergroup
anxiety?
|
|
“There aren't enough houses for this
population growth.”
|
Is there a capacity problem, and how much
is immigration contributing?
|
|
“Government has lost control.”
|
Are scale, speed or administrative
performance producing a control problem?
|
|
“Foreigners don't belong here.”
|
Has concern become generalized exclusion
or xenophobia?
|
Real life is less tidy than this table.
Several mechanisms can operate at once. Housing pressure can make immigration
more politically visible. Political rhetoric can turn uncertainty into
suspicion. A serious security incident can change perceptions of a much larger
group. Positive everyday contact can move in the opposite direction.
But keeping the mechanisms separate, instead
of examining them together, leads into one of the most common errors in
immigration politics: assuming that every expression of concern has the same
cause: Prejudice
Not every anxiety is
prejudice. Not every immigration concern is xenophobia.
But neither does a genuine concern make every explanation attached to it true.
If housing is scarce, the shortage is real.
Whether immigration is an important cause is a question of evidence.
If people feel unsafe, the feeling is real. Whether newcomers actually made
them less safe is another question.
Diagnosis means taking the concern
seriously without automatically accepting — or rejecting — the explanation
attached to it.
A Second Distinction: Immigration Never Starts From Zero
The E in E–I–σ adds another simple but important discipline: always look at
the society into which immigration is occurring.
Consider two towns receiving the same
number of newcomers.
One has experienced immigration for generations. Different languages are
routinely heard in its schools and shops, and local institutions know how to
help newcomers settle.
The other has experienced little immigration and has little institutional
experience with it.
Now suppose the first town has available
housing and needs workers, while the second already has a housing shortage and
overstretched schools.
The number arriving may be identical. The
social event clearly is not.
Every society already contains its own
mixture of groups, expectations, previous immigration, institutions, tensions
and ways of living together. Yesterday's immigrants may now be established
residents. What was once unfamiliar may have become normal. Old problems may
have been resolved, while others remain.
Every new immigration
episode starts from where society has already arrived.
This means that asking only “How many
immigrants?” starts too late.
We also need to ask what kind of society is
receiving them (E), what exactly is changing (I), and under what circumstances
(σ).
Those three questions — on E, I
and σ — allow us to move from the political symptom, “immigration
concern is rising,” toward a more useful question:
What is producing the
concern in this case?
The next step is to see how the nature and
speed of incoming change, together with housing, institutions, politics and
other surrounding conditions, can turn similar immigration numbers into very
different social outcomes.
What Improves the Diagnosis? - I and σ
To understand what is producing immigration
concerns – and why - in a particular case, we need already to look beyond the
number of people arriving.
Suppose 100,000 newcomers arrive in a
country. That figure tells us something, but not enough.
Did they arrive gradually or within a few months? Are they spread across the
country or concentrated in a handful of cities? Are they filling jobs for which
employers cannot find workers? How much housing needed immediately? How many
are expected to stay? Can they communicate easily with the people around them?
These differences are part of I, the
incoming change.
Now add the circumstances.
Are homes plentiful or scarce? Are schools coping? Is unemployment high or low?
Does government appear to know how many people are arriving and where they will
live? Is immigration receiving occasional attention or dominating the political
news?
These are part of σ.
The same number of
newcomers can therefore produce a very different problem depending on the speed
and character of the change and the circumstances surrounding it.
That sounds obvious. Its diagnostic value
becomes clearer when several conditions combine.
When Housing Becomes an Immigration Issue
Take a country with a serious housing
shortage.
The shortage began years earlier: too little construction, planning
constraints, rising prices and changing household demand have already made
homes scarce.
And now also Immigration increases rapidly.
The newcomers did not create the original
shortage. But they also need somewhere to live. Additional population now adds
demand to a market that was already under pressure.
A new political concern can emerge:
“We are bringing in people
faster than we can house them.”
This is more than a housing problem sitting
next to an immigration problem. The two have become connected in people's
understanding of what is happening.
E–I–σ
tells us what to investigate.
How much of the housing pressure existed
before immigration increased? How much additional demand is population growth
creating? Can housing supply respond quickly enough? Is the pressure national
or concentrated in particular places? Are other causes more important?
The result may be that immigration is an
important part of the problem, or a modest part, or being blamed for a shortage
caused mainly elsewhere.
The concern can be real
while the explanation attached to it can still be right, partly right, or
wrong.
This is one of the central uses of E–I–σ. It separates the concern from
the explanation and then tests how the pieces fit together.
The same logic applies elsewhere. A labor
shortage can make immigration economically useful while a housing shortage
makes the same immigration socially difficult. A shortage of school places may
be local rather than national. A slow asylum procedure can create a visible
impression of disorder even when total immigration is not exceptionally high.
Again: What appears politically as one
issue — immigration — may therefore contain several different problems.
Speed Can Matter as Much as Size
Societies can adjust, but adjustment takes
time.
Homes can be built. Schools can add
classrooms. Government agencies can hire staff. Employers can train workers.
Newcomers can learn a language. Neighbors can become familiar with one another.
That is why the speed of immigration
matters.
A society may accommodate a large change
over twenty years without much difficulty and struggle with a smaller change
compressed into two years. The problem is not necessarily that the final
population is too large. The problem may be that the change is moving faster
than housing, institutions or social adaptation can follow.
A useful immigration
number is therefore never just a number.
It is a number over time, entering a society with a particular capacity to adjust.
This brings us to one of the most useful
concepts that emerged from applying E–I–σ
to real cases: Absorptive Capacity.
Capacity Is More Than Housing
A society needs several kinds of capacity
when population changes.
It needs material capacity: homes,
transport, schools and healthcare.
It needs economic capacity: jobs and a labor market able to use incoming
skills.
It needs administrative capacity: immigration services, municipalities
and other institutions able to process and manage change.
And it needs social capacity: language learning, community
organizations, workplaces and ordinary opportunities for newcomers and
established residents to connect.
A country can be strong in one and weak in
another.
It may desperately need workers but have
too few homes. A town may have available housing but little experience settling
refugees. A government may have a sensible integration program that works well
for 20,000 people but cannot deliver the same quality when asked to serve
100,000.
The practical question is whether
the scale and speed of incoming change are aligned with the capacities
available at its time.
And Capacity is not a fixed national
ceiling. It can be built, eroded or temporarily overwhelmed.
E–I–σ
names that relationship capacity alignment.
Insufficient capacity alignment also
explains why a society can remain broadly positive toward immigrants and still
become concerned about immigration levels. Cultural familiarity does not create
houses. Tolerance does not add school places. A successful multicultural
history does not guarantee that administrative systems can expand indefinitely
at short notice.
At the same time, reducing immigration may
ease one capacity problem while creating another. Employers may lose workers,
universities students, or regions population they need.
So even here the question remains: which
problem, for whom?
Another Distinction: The People We Meet and the
Immigration We Hear About
There is another distinction that
repeatedly matters in practice.
A person may say:
“The immigrants I know are
good neighbors, but I still think immigration is too high.”
That is not necessarily inconsistent.
The first judgment is about people
encountered directly. The second may be about national population growth,
housing, border control, government competence or what the person sees in the
news.
Direct experience and the national
immigration picture are different sources of information.
Personal contact can make unfamiliar people
familiar. Research on intergroup contact broadly supports the idea that
constructive contact often reduces intergroup anxiety and prejudice.
But knowing an immigrant family personally cannot tell someone whether national
housing construction is keeping pace with population growth.
The reverse is also possible. Someone with
little direct contact with immigrants may nevertheless experience immigration
as a major issue because it dominates political debate and media coverage.
We can know immigrants
through experience while knowing immigration mainly through information.
E–I–σ
therefore asks which of the two is driving the
reaction.
If local experience is positive but
national anxiety is high, the explanation may lie less in everyday intergroup
contact and more in numbers, institutions, political framing or expectations
about the future.
That distinction becomes particularly
important when immigration is highly visible.
Why Some Problems Suddenly Become Bigger
Not every problem receives attention in
proportion to its size.
A housing shortage may exist for years
before immigration becomes linked to it.
A violent incident involving a newcomer can receive national attention while
thousands of uneventful encounters remain invisible.
An election campaign can turn immigration management into a test of whether
government is in control.
E–I–σ
uses the term salience for this: how
prominent an issue becomes in people's attention.
Salience does not tell us whether the
underlying concern is true or false. It tells us why it has become difficult to
ignore.
What becomes politically
prominent is not necessarily what is socially most consequential.
Diagnosis therefore has to
distinguish salience from substance.
Salience can amplify stress. Repetition, political conflict or dramatic incidents can make a
problem appear larger and more general than people's own experience suggests.
But visibility can also help. A
municipality that notices growing pressure on schools or neighborhood relations
early can act before the problem becomes politically explosive.
What matters is not only
what is happening, but also what people are seeing, hearing and connecting to
it.
What E–I–σ Now Lets Us Do
We can now return to the original political
symptom: “immigration concern is rising.”
Instead of treating that as the diagnosis, E–I–σ starts separating possible
causes.
|
What
appears to be the problem
|
What
E–I–σ asks us to check
|
|
“There are too many immigrants.”
|
Is the concern about people, or about the
scale and speed of population change relative to capacity?
|
|
“Housing is impossible because of
immigration.”
|
How much pressure predates immigration,
how much does immigration add, and can supply respond?
|
|
“Government has lost control.”
|
Are numbers changing rapidly,
administration failing, or political and media signals creating that
perception?
|
|
“They don't fit in.”
|
Is the problem unfamiliarity, language,
conflicting norms, weak integration, or generalized exclusion?
|
|
“My immigrant neighbours are fine, but
national immigration is too high.”
|
Are direct experience and system-level
concerns pointing to different mechanisms?
|
This is where E, I and σ
become more than labels.
They give us a disciplined way to move from
a broad political reaction to the mechanisms underneath it. The diagnosis may
point toward housing, immigration numbers, administrative competence,
integration, security, public information, prejudice — or several at once.
And that matters because the remedies are
not interchangeable.
Before deciding what to do
about immigration concern, find out what is causing it.
The next question is equally important:
causing stress for whom?
Immigration can reduce pressure for one group while increasing it for another.
To understand that, E–I–σ has to
move beyond the idea that a country has one single level of “immigration
stress”
Stress for Whom?
It is tempting to speak about “public
stress” as though a country experiences immigration collectively. In practice,
immigration can relieve pressure for one group while increasing it for another.
Imagine rapid immigration into a city with
a severe housing shortage but also a shortage of nurses, builders and
engineers.
A young renter may experience more
competition for housing. A hospital may experience relief because vacancies can
finally be filled. An employer may gain workers. A recently arrived family may
struggle to find a home. A homeowner may benefit from rising property values. A
municipality may face higher immediate costs for schools and services while
expecting a larger tax base later.
All of these effects can occur at the same
time.
There is no single
immigration experience because multiple groups experience immigration.
This is why E–I–σ asks a simple question whenever someone says that immigration
is causing stress: stress for whom?
The question is not intended to deny a
national problem. It prevents us from averaging away the people and mechanisms
that actually make up that problem.
One Policy Can Reduce Stress and Create It Elsewhere
Suppose government reduces immigration
sharply to relieve pressure on housing. Young renters may benefit if population
growth slows. But an employer dependent on foreign workers may experience a new
labor shortage. A hospital may find recruitment more difficult. A university
may lose international students and income. Families waiting for reunification
may face longer separation.
The policy may still be justified. Applying
E–I–σ does not suggest what to decide.
It simply makes the distribution of consequences harder to ignore.
Likewise, increasing immigration to solve a
labor shortage may be economically useful while adding pressure to housing or
local services.
Expanding refugee settlement may fulfil humanitarian obligations while creating
concentrated short-term demands on particular municipalities. Stronger
enforcement may increase one group's sense that government is in control while
increasing insecurity among newcomers or established migrant communities.
A policy that solves one
immigration-related problem can intensify another.
This is particularly important in political
debate because the group whose stress is most visible is not necessarily the
group experiencing the largest effect.
Employers may organize effectively around labor
shortages. Homeowners and renters experience housing very differently. A small
municipality receiving many newcomers can experience pressure that is almost
invisible in national averages. Newcomers themselves may have little political
voice while experiencing substantial insecurity or exclusion.
Good diagnosis therefore requires two
questions rather than one: what is the mechanism, and who is affected
by it?
Concerns Can Change Form
Social reactions also develop over time.
Consider an established resident who
initially feels uncertain around newcomers because communication is difficult.
That discomfort may fade as contact becomes routine. But it can also become
connected to other concerns.
As we have seen: If housing is scarce,
government appears unable to manage arrivals and political messages repeatedly
present newcomers as the cause, a personal uncertainty can become part of a
broader judgment: “immigration is changing the country too quickly and nobody
is in control.”
The reverse can happen as well. Better
communication, ordinary contact, functioning services and visible
administrative competence can reduce uncertainty and make change feel
manageable.
Social stress can grow,
change direction, attach itself to other problems — or diminish as people and
institutions adapt.
Some concerns arise without personal
unfamiliarity at all. Someone who has lived comfortably in a diverse neighborhood
for decades can still become worried about housing, school capacity or the
speed of national population growth. Conversely, someone can hold xenophobic
attitudes even where there is little direct immigration.
When Concerns Becomes a Judgment About People
This brings us to “xenophobia”.
E–I–σ
treats xenophobia differently from intergroup
anxiety or a practical concern about immigration levels. It involves a
generalized negative orientation toward people because they are perceived as
foreign or outsiders.
That distinction matters in both
directions.
Calling every housing or control concern
xenophobic prevents us from diagnosing a potentially real problem. But
presenting hostility toward foreigners as though it were merely a neutral
capacity concern makes the opposite error.
A useful test is to ask what happens to the
concern when the practical problem changes.
If more housing, better administration or
lower immigration substantially addresses the concern, the underlying mechanism
may indeed have been largely practical.
If the objection remains that particular people do not belong regardless of available
housing, employment, behavior or legal status, we are dealing with something
different.
E–I–σ takes concerns
seriously without assuming that all concerns are equally justified — or that
all have the same object.
Evidence remains necessary. A perceived
security threat may correspond to a real increase in risk, or an exaggerated
interpretation of isolated events, or a stereotype with little factual basis.
The model helps identify the question; it does not replace the evidence needed
to answer it.
Society Changes Too
Immigration does not end when newcomers
arrive.
People find jobs, learn languages, move neighborhoods,
make friends, form families, start businesses and participate in institutions.
Established residents acquire experience with them. Schools, employers and
municipalities learn what works and what does not. Political attitudes may
change.
In other words, the society receiving
immigration is itself changed by the experience.
This is easy to see historically. Groups
once regarded as newcomers become established parts of society. Their children
may no longer experience themselves as incoming at all. Food, language,
workplaces, neighborhoods and political representation change with them.
But adaptation is not automatic. Poor
settlement, discrimination, persistent unemployment, residential segregation or
repeated political conflict can leave problems in place or create new ones.
Today's immigration
changes the society that will receive tomorrow's immigration.
This feedback is important without needing
to make it complicated. A society that has successfully absorbed previous
immigration may be better prepared for later arrivals. A society that has
experienced institutional failure or prolonged conflict may approach the next
episode with less trust and greater sensitivity.
The circumstances can change as well. A
government may build more housing, improve processing, expand language programs
or restore confidence in border management. Alternatively, political
polarization or institutional failure may make the next phase harder.
E–I–σ
therefore treats immigration as a process, not a
one-time event.
From Problem to Direction
At this point the diagnostic logic becomes
practical.
When immigration concern rises, E–I–σ does not begin by asking whether
government should increase or reduce immigration. It first asks what kind of
problem is present.
|
If
the main problem is…
|
The
first direction to examine is…
|
|
Intergroup unfamiliarity
|
Language, contact, orientation and
opportunities for ordinary interaction
|
|
Housing or service overload
|
Capacity, geographic distribution,
population growth and the speed of I
|
|
Administrative loss of control
|
Processing, enforcement, coordination,
implementation and credible management
|
|
Labor shortage
|
Whether immigration can relieve the
shortage and whether supporting capacity can keep pace
|
|
Misinformation or distorted attribution
|
Evidence, communication and the
information environment
|
|
Xenophobic mobilization
|
Discrimination, political and social
norms, enforcement of rights, and the sources of generalized hostility
|
These are directions, not automatic
prescriptions. A real case may contain several problems, and policy choices
still involve costs, rights, obligations and political priorities.
But the table shows why diagnosis matters.
If the problem has been misidentified, even a forceful policy can miss its
target.
The purpose of E–I–σ is
not to tell policymakers what to think about immigration. It is to help them
see what they are dealing with before they decide what to do.
We can now examine whether this diagnostic
logic remains useful across very different real-world settings.
Germany, Australia, New Zealand and Canada
provide four very different immigration settings.
The challenge now is whether E–I–σ helps
us understand all four without forcing them into the same explanation.
Four Countries, Four Different Diagnoses
A diagnostic model becomes useful when it
helps us see real cases more clearly.
Germany, Australia, New Zealand and Canada
are useful precisely because they are not four versions of the same immigration
story.
Germany experienced an exceptional refugee and asylum shock.
Australia combines deep multicultural familiarity with growing concern about
immigration levels. New Zealand has deliberately built settlement policy around
both newcomers and receiving communities.
And Canada moved rapidly from broad confidence in immigration toward concern
about housing, services and management.
If we describe all four simply as countries
debating immigration, we lose much of what matters.
E–I–σ asks and explores what is
different underneath.
Germany: When Rapid Change Becomes a Question of Control
Germany's 2015 refugee crisis is the
clearest of the four cases in which speed and visibility changed the social
situation quickly.
Around 890,000 asylum seekers arrived during the year according to the later
corrected official estimate. Institutions had to register, accommodate and
process large numbers of people while political and public attention was
intense.
The incoming change was therefore not
simply “more immigration.” It was rapid, highly visible and associated with
refugees whose legal and settlement trajectories were often uncertain.
But Germany itself was not uniform.
Previous experience with immigration, direct contact with newcomers and
political attitudes differed substantially between regions. Research after 2015
found a strong increase in immigration concern, particularly in eastern
Germany. At the same time, other research found that greater local exposure to
refugees could reduce concern where contact was not dominated by large,
centralized reception facilities.
That apparent contradiction is
diagnostically useful.
People can become more
worried about immigration as a national event while becoming less worried about
immigrants they encounter locally.
The national picture was shaped by numbers,
political conflict, media attention and questions about whether government
remained in control.
Local experience could provide a different kind of information: actual people,
repeated contact and visible settlement.
This does not mean that all German concern
was merely a media effect. Accommodation, administration, language provision
and integration had to expand quickly. Nor does it mean that every fear was
supported by evidence. For example, later research found no evidence that
Chancellor Angela Merkel's 2015 “Wir schaffen das” decision itself created a
sustained “pull effect” increasing subsequent migration.
E–I–σ
therefore gives Germany a more precise diagnosis
than either “Germany became xenophobic” or “Germany simply received too many
refugees.”
Rapid incoming change met uneven local experience, institutional strain and
an exceptionally salient national debate. From that combination emerged a
wider concern about control.
Germany shows why
experienced immigration and nationally perceived immigration can move in
different directions.
Australia: Liking Immigration's Results While Questioning
Its Pace
Australia presents almost the opposite
starting point.
Immigration and multiculturalism are deeply
embedded in Australian society.
Recent social-cohesion surveys continue to find strong support for
multiculturalism and positive views of immigrants' economic and social
contribution. Everyday contact across cultural backgrounds is common.
Yet concern that immigration is too high
has risen.
If unfamiliarity with immigrants were our
main explanation, this would be difficult to understand. And E–I–σ points elsewhere.
Housing affordability and wider economic
pressure have become increasingly important in Australian public concern. Among
people saying immigration is too high, many nevertheless continue to say
multiculturalism is good and immigrants make positive contributions.
“Immigration is too high”
and “immigrants are good for Australia” can be held by the same person.
The distinction is crucial. At least part
of the concern is not a rejection of immigrants as people. It is a judgment
about the relationship between population growth and the country's capacity to
accommodate it.
Australia therefore demonstrates a limit to
what social familiarity can achieve. A society may be highly accustomed to
immigration and still experience pressure if housing, infrastructure or
services do not expand at the same pace.
At the same time, familiarity remains
important. It may help explain why concern about numbers can rise without
producing an equivalent collapse in support for multicultural society itself.
Australia shows that
social acceptance and absorptive capacity are different things.
New Zealand: Treating Settlement as a Two-Sided Process
New Zealand is useful for another reason.
It allows us to look at E–I–σ before
a major political crisis develops.
Its Migrant Settlement and Integration
Strategy does not treat successful immigration as something newcomers must
achieve alone.
Immigrants’ employment, housing, education, English, health, participation and
belonging are monitored as settlement outcomes. The Welcoming
Communities program adds the receiving side: local leadership,
communication, access to services, community connection, civic participation
and the ability of communities to welcome newcomers.
This amounts to a practical recognition
that immigration changes an existing social setting and that both sides of the
encounter matter.
The approach is not proof that New Zealand
has solved immigration stress. Evaluations still identify racism,
discrimination and uneven outcomes, and material problems such as housing and
employment remain real for some newcomers.
Its importance for E–I–σ lies elsewhere: the system looks for pressures before
they have to appear as a national political backlash.
New Zealand treats social
adaptation as something that can be observed, supported and adjusted — not
simply hoped for.
If language is a barrier, that can be
addressed. If newcomers lack social connections, local programs can help. If
housing remains difficult, welcoming rhetoric is not mistaken for a housing
policy. If some communities are not benefiting, monitoring can reveal it.
This is E–I–σ used preventively: pay attention to the incoming group, the
receiving community and the circumstances in which settlement is taking place,
then adjust when the combination is producing difficulty.
New Zealand shows that
immigration policy can include the society receiving immigration, not only the
people entering it.
Canada: When a Pro-Immigration Society Reaches a Capacity
Question
Canada provides perhaps the clearest
demonstration of why the E–I–σ distinctions
matter.
For decades, immigration has been closely
associated with Canada's national self-image. The country has extensive
immigration experience, large established immigrant communities and strong
multicultural norms.
Yet public opinion changed sharply. Federal
public-opinion tracking shows the share saying Canada accepts too many
immigrants rising from 22 percent in March 2023 to 54 percent in November 2024,
before easing to 47 percent in November 2025. Over roughly the same period,
concern about immigration's effect on housing and public services increased
substantially.
The obvious interpretation might be that
Canadians had become much more anti-immigrant.
But the surrounding evidence points to a
more complicated diagnosis.
Housing affordability was already a major
national problem. Population growth was rapid. Permanent immigration was
accompanied by substantial temporary migration. Confidence in government's
management of the immigration system was low. Surveys found housing, jobs,
economic capacity, services and government management among the main reasons
people gave for wanting lower immigration.
A society can remain
immigration-experienced and still conclude that immigration has become
misaligned with its capacity.
Canada consequently began reducing planned
immigration levels and, for the first time, explicitly incorporating temporary
residents into population planning. The policy itself acknowledged the
relationship between immigration, housing, services and infrastructure.
Public concern eased somewhat after its
2024 peak, but that does not establish that the policy change caused the shift.
What the case demonstrates is the diagnostic sequence: favorable attitudes
toward immigrants did not prevent concern when the scale and speed of
population growth became associated with housing pressure and weak confidence
in management.
Canada therefore warns against two opposite
mistakes.
One is to dismiss concern as xenophobia because it arises in an immigration
debate.
The other is to assume that every claimed effect of immigration is therefore
factually correct.
Take the concern
seriously; then test the explanation.

E–I–σ captures alle cases. The

E–I–σ helps explain why
similar immigration debates can arise from very different combinations of
social conditions.
That makes the final question less about
immigration itself and more about political judgment: once the diagnosis is
clearer, what can government reasonably change — and what choices remain
political rather than diagnostic?
From Diagnosis to Political
Choice
E–I–σ can improve the
diagnosis. It does not replace political judgment.
The model cannot decide how many immigrants
a country should admit, which obligations should take priority, or how costs
and benefits should be distributed. Those remain political choices involving
economic needs, humanitarian obligations, rights, national priorities and
democratic preferences.
But political choices improve when
governments understand which problem they are trying to solve. If the pressure
is housing, the relevant questions concern housing supply, population growth
and capacity alignment.
If the problem is administrative control, the focus shifts to processing,
enforcement, coordination and the scale or speed of incoming change.
If unfamiliarity is driving anxiety, language, integration and ordinary contact
matter.
If claims about immigration are unsupported by evidence, the attribution itself
must be tested.
If xenophobia is the problem, calling it a capacity concern will not make it
disappear.
Immigration policy
therefore cannot be separated completely from housing policy, labor policy,
education, public administration, integration, security or political
communication. Immigration policy is also social policy.
The contribution of E–I–σ is consequently
modest but consequential:
Before deciding what to
do about immigration, determine what immigration is actually doing in this
society, under these circumstances, and to whom.
For readers who want the analytical
machinery behind that proposition, the appendix sets out the model, its
principal concepts and a procedure for applying it to a case.
Appendix — How the E–I–σ Model
Works
Technical companion to The E–I–σ Framework
The main article introduces E–I–σ through the problems it helps
diagnose.
This appendix sets out the model itself more systematically: its
components, the mechanisms connecting them, and a practical procedure for
applying it to a case.
E–I–σ
is a diagnostic synthesis. It brings together
established insights about intergroup relations, perceived threat, contact and
adaptation with material, institutional and political conditions surrounding
immigration. Its purpose is to organize those mechanisms into one usable
structure.
A.1 The Basic Model
Social outcomes associated
with immigration arise from the interaction of E, I and σ.
|
Component
|
Meaning
|
Central
question
|
|
E
|
Existing Social Configuration
|
What society is receiving the change?
|
|
I
|
Incoming Group Configuration
|
What population change is entering it?
|
|
σ
|
Contextual Sensitivities
|
Under what circumstances are E and I
meeting?
|
E, I
and σ are not three independent causes whose effects can simply be added
together. Their diagnostic significance lies in their interaction.
The model therefore asks
not only what conditions are present, but what their combination is producing.
A.2 E — Existing Social Configuration
E describes
the society as it exists when the immigration change being examined occurs.
Immigration never enters an empty social space.
Relevant dimensions may include:
·
existing groups and demographic
composition;
·
previous immigration experience
and accumulated familiarity with diversity;
·
relations among established
groups, including cohesion, polarization and prior conflict;
·
institutional trust and
experience in managing migration and settlement;
·
existing attitudes toward
outsiders and established social norms;
·
economic and social
inequalities; and
·
previous successful or
unsuccessful experiences of integration.
These are dimensions to inspect, not
variables that must all be scored. Their relevance depends on the case.
E is accumulated social
history. Previous immigration can become part of the society that receives the
next immigration.
This is why E changes over time.
Newcomers find work, establish families and organizations, participate in
institutions and become neighbours and citizens. What was once incoming change
can become part of the existing configuration against which later change is
experienced.
A.3 I — Incoming Group Configuration
I describes
the socially consequential incoming population change. Numbers matter, but they
are only one characteristic.
Relevant dimensions may include:
·
scale — how many people are
arriving;
·
velocity — how quickly the
change occurs;
·
composition — for example
workers, refugees, students or family migrants;
·
expected duration — temporary,
uncertain or long-term settlement;
·
geographic concentration and
settlement pattern;
·
economic role, skills and
labour-market position;
·
language, cultural practices
and the degree of familiarity to established groups;
·
legal status and uncertainty
surrounding status; and
·
visibility in everyday life and
public debate.
For diagnostic purposes, I should follow
the social effect rather than only the administrative category. Permanent
immigrants, temporary workers and international students may be governed
through different programmes, but if all contribute to housing demand, a
housing analysis may need to consider their combined effect.
The relevant I is the
incoming change that matters to the mechanism being examined.
A.4 σ — Contextual Sensitivities
σ describes
the surrounding conditions that can amplify, dampen or redirect what happens
when E encounters I.
|
Domain
|
Examples
|
|
Material
|
Housing, jobs, wages, schools,
healthcare, transport and infrastructure
|
|
Institutional
|
Administrative capacity, implementation
quality, migration management, legal frameworks and institutional trust
|
|
Political
|
Government credibility, party
competition, rhetoric, polarization and perceived control
|
|
Information
|
Media and social media narratives,
misinformation, prominent incidents and public salience
|
|
Social / historical
|
Previous migration experience, historical
memory, civil society, community relations and existing tensions
|
|
Security
|
Actual or perceived security risks,
enforcement and the interpretation of incidents
|
σ is
dynamic. Economic conditions change, governments gain or lose trust, political
rhetoric shifts, institutions learn, and particular events can suddenly make
immigration more prominent.
The same E meeting a
similar I can therefore produce different outcomes under different σ
conditions.
A.5 How E, I and σ Produce => Outcomes
Three pathways are particularly useful for
diagnosis. They can operate separately or simultaneously.
Pathway 1 — Personal Encounter
Encounters with unfamiliar out-group
members can produce uncertainty, discomfort or vigilance. Social psychology
commonly describes this as intergroup anxiety (see also Stephan & Stephan).
Language barriers, uncertainty about social expectations and limited prior
contact can contribute.
Repeated benign contact, greater
familiarity and successful communication can reduce this anxiety. Negative
encounters, stereotypes or threatening interpretations can reinforce it.
Unfamiliarity can produce
anxiety without implying xenophobia.
Pathway 2 — Structural or Situational Pressure
Immigration-related concern does not
require interpersonal anxiety. Material or institutional conditions can
generate pressure independently.
Rapid population growth may increase demand
for scarce housing. A municipality may face additional school costs. An
employer may benefit from additional labour. An asylum system may become
overloaded. These effects can be experienced by people who are entirely
comfortable with immigrants as neighbours or colleagues.
A structural immigration
concern can exist without a negative judgment about immigrants as people.
Pathway 3 — Combination and Emergence
Conditions can also combine into a
higher-level concern or adaptive outcome that is not adequately represented by
any component separately.
For example:
Rapid immigration +
housing scarcity + visible administrative difficulty + intense political
attention → “The country has lost control.”
The same logic can work positively:
Language acquisition +
employment + constructive local contact + competent settlement institutions →
greater familiarity, participation and belonging.
E–I–σ
uses emergence to describe these combination
effects. It is not restricted to negative outcomes.
A.6 Four Concepts That Modify the Interaction
Intergroup Anxiety
Personal anxiety, discomfort, uncertainty
or vigilance that may arise in encounters with unfamiliar out-group members,
behaviours or expectations. It is a response, not a synonym for prejudice or
xenophobia.
Salience
The degree to which an E–I–σ condition becomes prominent in public or institutional
attention. Salience can be increased by political conflict, repeated media
attention, dramatic incidents or association with another major problem such as
housing. Institutional salience can also be useful when it makes emerging
problems visible early enough for preventive action.
Absorptive Capacity
The ability of an existing social
configuration, under prevailing contextual conditions, to incorporate a given
scale and velocity of incoming change without producing avoidable material,
administrative or social-system overload.
Capacity can be considered in several
forms:
- material capacity — housing,
schools, healthcare and infrastructure;
- administrative capacity —
processing, coordination and service delivery;
- economic capacity — employment
and the ability to use incoming labour and skills; and
- social-integration capacity —
language provision, local institutions, community organizations and
opportunities for social connection.
Capacity Alignment
Capacity alignment asks whether the actual
scale and speed of I are reasonably matched by the relevant capacities of E
under prevailing σ conditions.
Capacity is not fixed: it can be expanded,
weakened or temporarily exceeded as material, administrative, economic and
social-integration conditions change.
Absorptive capacity asks
what the society can accommodate. Capacity alignment asks whether the
immigration actually taking place is aligned with that capacity.
A favourable attitude toward immigration
can increase social resilience, but it cannot substitute for material or
administrative capacity. Conversely, high capacity in one domain does not
guarantee high capacity in another.
A.7 Group-Specific Outcomes and Feedback
The model does not assume that a society
has one single level of immigration stress. Different groups can experience the
same immigration episode differently.
For formal analysis, this can be
represented as Sᵍ: the immigration-related social stress experienced by group g.
E + I + σ → different
outcomes, including different Sᵍ,
for different groups.
A renter, employer, homeowner, newcomer,
established minority, municipality and national government may therefore
experience different costs, benefits, anxieties and opportunities.
Outcomes also feed back into the system.
Successful settlement can increase familiarity and institutional competence.
Poor implementation can reduce trust. Political mobilization can change
attitudes. Xenophobia can generate discrimination and avoidance, thereby
increasing stress among newcomers and altering the social environment for later
immigration.
Today's I can become part
of tomorrow's E, while today's outcomes can change tomorrow's σ.
A more formal representation is:
E₀ + I + σ₀ → appraisal
and experience → group-specific outcomes (Sᵍ) → behaviour, adaptation and policy → E₁ + σ₁
The subscripts simply indicate change over
time: the society and circumstances after an immigration episode need not be
the same as those that existed before it.
A.8 Applying E–I–σ to a Case
A full E–I–σ
analysis can be organized around the following sequence:
|
1.
Map E
|
What society existed when the incoming
change occurred? Which characteristics are relevant to this case?
|
|
2.
Profile I
|
What changed, how much, how quickly,
through which migration streams, and where?
|
|
3.
Assess σ
|
What material, institutional, political,
informational, social/historical and security conditions surrounded the
change?
|
|
4.
Identify the mechanism
|
Is the observed concern driven mainly by
personal unfamiliarity, structural pressure, an emergent combination, or
several mechanisms?
|
|
5.
Ask “for whom?”
|
Which groups experience stress, benefit,
adaptation or displacement of pressure?
|
|
6.
Compare experience and system-level perception
|
What is being learned through direct
contact, and what is being understood mainly through statistics, politics,
media or national debate?
|
|
7.
Check capacity and alignment
|
Which capacities are adequate, strained
or mismatched with the scale and velocity of I?
|
|
8.
Trace feedback
|
How are behaviour, experience, political
reaction and policy changing the receiving society or surrounding
circumstances?
|
|
9.
Identify policy leverage
|
Which diagnosed mechanisms can government
or other institutions realistically influence?
|

The diagram summarizes the complete logic. E
and I meet under prevailing σ conditions; the interaction can
operate through personal encounter, structural pressure and combination
effects; outcomes differ across groups; and behaviour, adaptation and policy
feed into the society and circumstances that shape the next immigration episode.
Salience, direct versus system-level
experience, absorptive capacity and capacity alignment help explain why
particular mechanisms become more or less important in a given case.
The diagnostic purpose remains simple:
