Trust is recognized as an important factor that mediates many aspects of human behavior (Camerer, 2003). Definitions of trust vary but a widely accepted one is that it is a psychological state comprising the intention to accept vulnerability based upon positive expectations of the intentions or behavior of another. Therefore, a person (the trustor) who depends on someone else (the trustee) expects to reduce the likelihood or size of a negative outcome in some situation, such as when that dependence is misplaced, the expected value of the outcome is lower.
