Trust and trustworthiness are commonly mentioned as an element of the relational dimension of social capital. The other dimensions of social capital being the structural and cognitive dimensions. This conceptualisation, distinguishing between structural, relational, and cognitive dimensions, is one of the major approaches to social capital. This approach was systematically explored and elucidated by Nahapiet & Ghoshal (1998) building on Granovetter’s (1992) discussion of structural and relational embeddedness.
Trust is essential for the existence of social capital and most authors agree that trust and trustworthiness are at the core of social capital. Trust is often mentioned specifically in definitions of social capital, for example, “connections among individuals—social networks and the norms of reciprocity and trustworthiness that arise from them”. Some authors even equate trust with social capital, such as Francis Fukuyama. Trust is vital for any form of social interaction or exchange and trustworthiness ‘lubricates social life’.
Social interaction and exchange without trust would be virtually impossible
Effective collective action requires high levels of trust and perceptions of trustworthiness. Trust makes it possible to maintain peaceful and stable social relations that are the basis for collective behaviour and productive cooperation. Social interaction and exchange without trust would be virtually impossible and all economic activity requires at least a minimum level of trust. Without trust actors would not have the confidence that others would uphold their expectations and obligations and would be unwilling to participate with others.
Trust is complex and multifaceted, extensive discussion of trust and social capital is beyond the scope of this article. For detailed discussion see Fukuyama, 1995; Glaeser et al., 2000; Newton, 2001; Nooteboom, 2006; Son & Feng, 2019; Tsai & Ghoshal, 1998.
Trust exists between people who know each other well, and between strangers
Trust can be built within relationships, on a personal basis, but it may also arise outside relationships, more impersonally, on the basis of socialisation and within the context of coordinating institutions. A simplified distinction is trust between people who know each other well, and trust between strangers. The former is based on reputation and experience and is often called “particularised”, “personalised”, “situated”, “relational”, or “thick” trust and the latter is based on beliefs and predispositions and is often called “generalised”, “social”, or “thin” trust.
When talking about the trustworthiness of an individual we are referring to their reputation, their track record of fulfilling on promises and obligations, being fair, and not being exploitive. When talking about trustworthiness of others – not a specific person – we are referring to norms and shared understandings. However, in both cases we cannot discount the influence of the personal experiences of the observer, i.e. their lifeworld.
Depending on the conceptual approach to social capital and the level of interest (micro to macro), one or both types of trust may be relevant. At the micro or meso level when the focus is on individual social capital or it has private good qualities, relational trust is clearly important. Generally, social trust should not be ignored since there is evidence that social trust influences relational trust. At the meso and macro levels where social capital has public good qualities, social trust is most important. Social trust is normative and related to morals and faith in others rather than information and experience with specific individuals. Social trust is also related to the human instinctual disposition to trust and be trustworthy.
Trust could be considered the acceptance of risk and vulnerability
From some theoretical perspectives trust could be considered the acceptance of risk and vulnerability related to the actions of others and an expectation that the other will not exploit this vulnerability. This view is popular in ration-choice approaches that tend to treat trust as a probability and therefore a rational calculation. As stated by Gambetta (1988), “when we say we trust someone or that someone is trustworthy, we implicitly mean that the probability that he will perform an action that is beneficial…is high enough for us to consider in engaging in some form of cooperation with him.” However, rationality is only part of the explanation for trust and trustworthiness since people trust more than is rationally appropriate out of a sense of moral attachment.
Institutions can play an important role in perceptions of trust and trustworthiness. Institutions of all types can facilitate the development of shared norms and shared cognitive understandings that provide the foundation for perceptions of trust and trustworthiness. Institutions can mitigate many perceived vulnerabilities, creating confidence in the degree of trustworthiness. These institutional structures help to create and recreate norms and shared understandings.
Are trust and trustworthiness aspects of the relational or cognitive dimension of social capital?
From the discussion above we could conclude that relational trust is part of the relational since it relates to the specific characteristics of social relationships. However, social trust is cognitive since it relates to more general perceptions and beliefs that do not relate to specific individuals. Trustworthiness relates to reputation in the context of relational trust, and to norms and shared understandings in the context of social trust.
Trust is a calculation and predisposition that is socially and culturally situated, so has an element of intersubjectivity, and is grounded in subjective experience.
