Trust is the willingness of one party (the trustor) to become vulnerable to another party (the trustee) on the presumption that the trustee will act in ways that benefit the trustor. In addition, the trustor does not have control over the actions of the trustee. Scholars distinguish between generalized trust (also known as social trust), which is the extension of trust to a relatively large circle of unfamiliar others, and particularized trust, which is contingent on a specific situation or a specific relationship. As the trustor is uncertain about the outcome of the trustee's actions, the trustor can only develop and evaluate expectations. Such expectations are formed with a view to the motivations of the trustee, dependent on their characteristics, the situation, and their interaction. The uncertainty stems from the risk of failure or harm to the trustor if the trustee does not behave as desired. In the social sciences, the subtleties of trust are a subject of ongoing research. In sociology and psychology, the degree to which one party trusts another is a measure of belief in the honesty, fairness, or benevolence of another party. The term "confidence" is more appropriate for a belief in the competence of the other party. A failure in trust may be forgiven more easily if it is interpreted as a failure of competence rather than a lack of benevolence or honesty. In economics, trust is often conceptualized as reliability in transactions. In all cases, trust is a heuristic decision rule, allowing the human to deal with complexities that would require unrealistic effort in rational reasoning. Sociology Sociology claims trust is one of several social constructs; an element of the social reality. Other constructs frequently discussed together with trust include control, confidence, risk, meaning and power. Trust is naturally attributable to relationships between social actors, both individuals and groups (social systems). Sociology is concerned with the position and role of trust in social systems. Interest in trust has grown significantly since the early eighties, from the early works of Luhmann, Barber and Giddens (see for a more detailed overview). This growth of interest in trust has been stimulated by ongoing changes in society, specifically known as late modernity and post-modernity. Sviatoslav contended that society needs trust because it increasingly finds itself operating at the edge between confidence in what is known from everyday experience and contingency of new possibilities. Without trust, one should always
