Almost 30 per cent of the 255 399 answers say that ‘most people can be trusted’. The individual country G-trusts are listed in the Appendix to this chapter. Justiﬁed trust reduces transaction and monitoring costs. It saves time and trouble the higher it is in society. It is thus a factor of production – it will be demonstrated that it is not a powerful one. Any country has a level of justiﬁable trust. If you have more trust than that, you are a ‘sucker’ that other people exploit. If you have less trust, you are a ‘cynic’, who creates costs and trouble for other people. Most prefer to deal with reasonable people, who are realistic by being close to the justiﬁable level. By the law of large numbers we get: Thesis The Rationality Theorem of Trust: trust is rational for society at large. We may measure it poorly and individuals deviate to both sides, but the G-trust is rational and an important characteristic of a society. The G-trusts of the 188 polls are depicted on Figure 21.1, which shows that they have a...
