Randomly Selected Representative Committees

Situations where decisions are made by a committee rather than the entire society are quite common in the real world. When selecting a committee that decides for an entire body of members of a society (a court, legislature, etc.) there are two usual methods: random selection and direct selection (whereby the latter method is made by some authority). It is known that both methods have some flaws (Hasday, 2017). We present a new committee selection method that has the core benefits of random selection (equal opportunity, no manipulation) and direct selection (the possibility of representativeness) while avoiding their pitfalls. The new method consists of randomly selecting a committee from a pool of “matching” committees so that all members in the society have equal opportunities of being selected and properties of representativeness and coherence are fulfilled
