Technology and social cohesion

Social cohesion is the trust, shared norms and ties that let people cooperate across differences. Technology can strengthen it by connecting people and improving services, or weaken it through polarisation, surveillance, exclusion and loss of shared information. This page sets out how technology affects trust and participation, how cohesion is measured, and what evidence serves the governments and civil society organizations concerned.

01In brief

The short answer.

Social cohesion is the trust, shared norms and connections that let people cooperate across differences. Technology can strengthen it by connecting people and improving services, or weaken it through sorting into like-minded groups, surveillance and exclusion. Trust in institutions shapes whether people follow guidance in crises.

02Geography

People and exposure in Latin America and the Caribbean.

For technology and social cohesion, in GCRI's spatial-intelligence reading, the map opens on population density, true-colour imagery and night lights with relief in 3D and true colour from NASA GIBS, framed on Latin America and the Caribbean; every other NASA layer, live feed and forecast waits in the layer list.

The interactive map needs JavaScript; the layer list and sources are below.

03The question

Technology and social cohesion: how the risk develops.

Trust, misinformation and public outcomes. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

Mechanism

Networks connect and sort

Digital networks let people find others with shared interests, which can build communities and also sort people into like-minded groups.

Mechanism

Surveillance erodes trust

When people believe they are watched, they may withdraw from public participation, especially groups that have been targeted before.

Mechanism

Exclusion divides

People without access or skills are left out of digital public services and conversations, widening social gaps.

Mechanism

Institutions anchor trust

Trust in institutions shapes whether people follow official guidance in crises and accept collective decisions they disagree with.

04Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
Generalised trustThe belief that most people can be trusted, measured in values surveys.
Affective polarisationDislike and distrust between people who identify with opposing political groups.
Digital exclusionLack of access, skills or confidence to use digital technologies and services.
05Indicators

What is measured, and how well.

Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.

06Canvas

From sources to decisions.

The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

09Core questions

The questions experts ask.

  • How does trust in institutions affect compliance with public health or evacuation advice?
  • How does misinformation spread, and what reduces its effects?
  • Who is excluded by digital-only services, and with what consequences?
  • How do online networks affect polarization and social cohesion?
  • How does automated decision-making affect fairness in public services?
10Mechanisms

Trust, information and exclusion.

Trust shapes behaviour. During epidemics and disasters, people are more likely to follow guidance from sources they trust, and trust is built or lost by how institutions act over time. Misinformation spreads through social networks, often faster than corrections, especially when it is emotionally charged or aligned with existing beliefs. Prebunking, accurate and timely information from trusted messengers and community engagement are among the approaches with supporting evidence.

Digital exclusion follows lines of age, income, disability, gender and geography. When services move online, people without connectivity, devices, skills or digital identity can lose access to benefits and information. Algorithmic systems used in public services can reproduce bias in their training data. Cohesion is also affected by perceived fairness: crises that appear to burden some groups unfairly erode solidarity.

Design choices matter. Services that keep offline and assisted channels, explain automated decisions and allow appeal tend to preserve trust and inclusion, while opaque systems that cannot be challenged erode both, even when they are efficient on average.

11Methods and data

Methods and limits.

Surveys

Trust and attitudes

Surveys track trust, beliefs and behaviour; responses can differ from actions.

Networks

Information diffusion

Analysis of how content spreads on platforms; access to platform data is restricted.

Experiments

Interventions

Field and online experiments test messaging and correction; effects can fade.

Limits: platform data access is uneven and changing, causal effects of exposure to misinformation are hard to isolate, and findings from one country or platform may not transfer.

13Questions

Questions and answers.

What is social cohesion?
The extent of trust, shared values and connections among people and groups in a society, which enables cooperation and peaceful resolution of differences.
Does social media cause polarisation?
Research is mixed. Some studies find effects on attitudes and others find small ones; effects likely vary by platform, country and group.
Why does trust matter in a crisis?
Because people are more likely to follow public guidance and support collective measures when they trust institutions and each other.
Does the platform fact-check content?
No. It studies how information and trust shape public outcomes. Fact-checking and content decisions belong to others.
Is technology good or bad for cohesion?
Evidence shows both effects, depending on design, governance and context.
Does the platform study specific platforms?
Where data access allows, under research ethics and data protection.
