The Trust Deficit: How Social Cohesion Is Unraveling

← Back to All Articles

Social trust — the degree to which people trust strangers, neighbors, and fellow citizens they have never met — is one of the most powerful predictors of a society’s health. High-trust societies have stronger economies, lower crime rates, more effective governments, and higher levels of individual wellbeing. America’s social trust has been declining for decades. Today, only about 30% of Americans say that most people can be trusted. The consequences are everywhere, and they compound.

What Social Trust Is and Why It Matters

When sociologists measure social trust, they typically use a simple question: “Generally speaking, would you say that most people can be trusted, or that you can’t be too careful in dealing with people?” The answers, aggregated across large representative samples over time, tell us something important about how a society functions. In high-trust societies — Scandinavia, the Netherlands, Canada — the answer “most people can be trusted” is the majority response. In low-trust societies, it is the minority.

Social trust enables cooperation without requiring constant verification, contracts, or surveillance. It makes economic transactions lower-cost. It makes civic cooperation easier. It makes communities more capable of collective action. Robert Putnam’s decades of research established that high social capital — the network of relationships and the trust that underlies them — is one of the strongest predictors of everything from educational achievement to child welfare to economic growth.

America’s Declining Trust

In the late 1960s, approximately 55 to 60% of Americans reported trusting most people. That number has fallen consistently since. By the early 1990s it had dropped to around 45%. By 2010 it was near 40%. Today it hovers around 30%, with significant variation by age group: younger Americans report strikingly lower levels of trust than older generations at the same age. The decline is not simply a matter of people getting older and more cynical — it represents a genuine generational shift in baseline social trust.

The geographic and demographic breakdowns reveal additional fault lines. Trust varies significantly by income, education, race, and community type. Wealthier, more educated, and more homogeneous communities tend to maintain higher trust. Communities experiencing rapid demographic change, economic distress, or high crime tend toward lower trust. These patterns create feedback loops: lower trust makes collective problems harder to solve, which makes conditions worse, which lowers trust further.

“Trust is the invisible infrastructure of a functioning society. When it is abundant, everything works more easily. When it erodes, every institution, every transaction, every community relationship becomes more difficult and more costly.”

What Is Destroying Trust

Multiple forces are operating simultaneously. Income inequality — at levels not seen since the Gilded Age — creates a society in which people’s experiences and interests diverge so sharply that they find it difficult to believe others share their concerns. Political polarization has transformed civic life into a zero-sum contest between teams who regard each other not as fellow citizens but as enemies. The decline of institutions that once built cross-cutting relationships — religious congregations, civic organizations, unions, neighborhood associations — has removed the social infrastructure through which trust between strangers was once built and maintained.

Social media has accelerated all of these trends. Platforms optimized for engagement systematically surface content that divides rather than unites, that confirms existing beliefs rather than challenging them, and that portrays the other side as not just wrong but threatening. The daily diet of outrage and tribalism that most Americans now consume through their phones is actively corrosive to the social trust that makes civil society possible.

What This Means for the Index

The Moral Decay Index places social trust at the center of its framework because it is foundational to everything else the index tracks. A society with high social trust can solve problems collectively, maintain civic institutions, and recover from shocks. A society with declining trust becomes progressively less capable of all of these things. The 30% figure is not just a data point. It is a measure of how much social cohesion America has already lost — and a warning about the accelerating cost of losing more.
