 abstract={A golden ratio has been applied since ancient times in many areas, starting with architecture and art, and nowadays in modern financial markets and contemporary physics. This paper defines a golden rule in a set of preferences, generalizing the problem of group choice and the 2/3 rule of Łyko by means of a golden number corresponding to the ratio of lengths of sides in a golden rectangle},
