Los Horcones does not use the Planner-Manager governance system described in "Walden Two." They refer to their governance system as a "personocracy". This system has been "developed through ongoing experimentation". In contrast to Twin Oaks, Los Horcones "has remained strongly committed to an experimental science of human behavior and has described itself as the only true Walden Two community in existence." In 1989, B. F. Skinner said that Los Horcones "comes closest to the idea of the 'engineered utopia' that he put forth in "Walden Two"".
