The Idea of Best Ideas refers to the concept of reaching the best ideas through constant improvement of an idea, constant scrutiny, and collaboration with multiple minds. It relies on the premise that an idea should be able to stand on its own merit, therefore any proponents of an idea that ask that the idea not be questioned must fear that it cannot stand against scrutiny, thus it must not be the best idea. If the goal is to get to the best idea, or if the goal is to improve an idea, the idea must be secure enough to accept feedback or criticism.
This process is basically the scientific method for ideas. A person who originates an idea without being open to improvements on the idea is doing so not for the sake of the idea, but for the sake of their own ego or they require validation or recognition. Because Loricism espouses the Idea of Best Ideas, it must always remain open to critique and suggestions for improvement.
