What is the game to build trust?

Tim Ferriss discussed the concept of a "trust menu" as an effective game or strategy to build trust, especially in situations of initial distrust. This involves creating a prearranged set of signals or actions that each party can take, which are small but significant enough to indicate mutual respect and trustworthiness. The process allows each party to take turns in demonstrating trustworthiness through agreed-upon actions, thereby gradually building a foundation of trust. The idea is to start with small, manageable steps that can lead to more substantial trust-building interactions 1.
