«Economists have only partly captured what is meant by trust or belief. Their view suggests that confidence is rational: people use the information at hand to make rational predictions; they then make a rational decision based on those rational predictions. Certainly people often do make deciosions, confidently, in this way. But there is more to the notion of confidence. The very meaning of trust is that we go beyond the rational. Indeed the truly trusting person often discards or discounts certain information. She may not even process the information that is available to her rationally; even if she has processed it rationally, she still may not act on it rationally. She acts according to what she trusts to be true.»
