Generalized Trust Scale
Also known as: GTS, Trust in Strangers
The Generalized Trust Scale measures an individual's propensity to trust people in general, particularly strangers with whom they have no direct relationship. Originally developed by Morris Rosenberg in 1956 and later refined by Toshio Yamagishi and colleagues, it has become foundational in research on social capital, civic participation, and intergroup relations.
Key highlights
- Extensively validated across 50+ countries with strong psychometric properties
- Strongly associated with civic participation, volunteering, and institutional trust—robust criterion validity
- Brief and low-burden administration; easily embedded in multi-item surveys
- Theoretically grounded in social capital and reciprocal altruism literature
- Sensitive to historical and institutional context, useful for before–after policy or conflict research

When to use it
Generalized trust is measured in cross-national surveys, civic engagement studies, social capital research, and investigations of intergroup prejudice. It is particularly valuable in comparative political sociology, post-conflict reconciliation research, and studies linking social attitudes to institutional participation. Appropriate for adult populations; adapted versions exist for adolescents.
Strengths & limitations
- Extensively validated across 50+ countries with strong psychometric properties
- Strongly associated with civic participation, volunteering, and institutional trust—robust criterion validity
- Brief and low-burden administration; easily embedded in multi-item surveys
- Theoretically grounded in social capital and reciprocal altruism literature
- Sensitive to historical and institutional context, useful for before–after policy or conflict research
- Unidimensional; does not distinguish between optimistic (benevolence) and prudent (competence) bases of trust
- Subject to cultural and linguistic interpretation of 'most people' and 'trust'
- Lacks specificity regarding institutional trust versus interpersonal trust
- Susceptible to social desirability bias in face-to-face administration

Frequently asked
Is generalized trust the same as institutional trust?
No. Generalized trust refers to trust in people generally (horizontal, interpersonal). Institutional trust refers to confidence in formal organizations (vertical). Both are important; they are correlated but distinct. A person may distrust government institutions while maintaining high generalized trust in neighbors.
What is a typical score, and how do I interpret individual variation?
In most Western democracies, mean scores on a 5-point scale range 2.8–3.8, with standard deviation approximately 0.9–1.1. Scores 1.0–2.4 suggest low trust; 2.5–3.4 moderate; 3.5–5.0 high. Compare individual scores to the sample or population mean rather than absolute thresholds.
Does generalized trust measure optimism or realistic assessment?
Both. Research shows that generalized trust is neither blind optimism nor cynical realism but rather an adaptive heuristic. High-trust individuals cooperate more, which in well-functioning societies generates returns. In dysfunctional environments, high trust may reflect naiveté. Context matters.
Can generalized trust be increased or is it stable?
Empirically, it is relatively stable within individuals over years but responsive to significant events (conflict, economic crisis, institutional breakdown). At the societal level, recovery of trust after crises typically requires years or decades. Targeted contact and cooperative institution-building show modest effects on increasing trust.
