Anarchists have many ideas about how decisions would be made in a truly voluntary and cooperative society. Most anarchists believe that such a society must be based on local communities small enough for people know each other, or people at least would share ties of family, friendship, opinions or interests with almost everybody else. And because this is a local community, people also share common knowledge of their community and its environment. They know that they will have to live with the consequences of their decisions. Unlike politicians or bureaucrats, who decide for other people.
