Quotes

The primary property of trust that is used in our work is transitivity. Trust is not perfectly transitive in the mathematical sense; that is, if Alice highly trusts Bob, and Bob highly trusts Chuck, it does not always and exactly follow that Alice will highly trust Chuck. There is, however, a notion that trust can be passed between people. When we ask a trusted friend for an opinion about a plumber, we are taking the friend's opinion and incorporating that to help form a preliminary opinion of the plumber. In application, the transitivity of trust can work in two ways. First, a person can maintain two types of trust in another person: trust in the person, and trust in the person's recommendations of other people. Alice may trust Bob about movies, but not trust him at all to recommend other people whose opinion about movies is worth considering.
