🪧 Same Game: Proving What Cannot Be Seen

One structure, five settings: how a claim becomes believable when the other side cannot check it.

A used car, a loan book, a central bank, a nuclear deterrent, and a player threatening to sit out share a structure. One side holds information the other cannot verify, and words alone move nothing, because a statement that costs a liar nothing tells a listener nothing.

What separates types is expense. A signal works when it costs more for the party who would be lying, and screening works when the uninformed side offers a menu that different types accept differently. Once you can spot that requirement, the same test applies everywhere: what would it cost this actor to be faking, and who would find out?
