Scale of Cultural Development

Dr. Roeland Richter first published the Richter Scale of Cultures in 2203. Since then it has become the Federation's most important tool for determining at which point in a civilization's development the Prime Directive no longer need apply. Most first contacts missions take place when a society reaches a classification of G. Exceptions include planets that do not wish contact, planets that were already contacted by non-federation agencies, and planets that were contacted before the Richter Scale of Cultures was devised. The classifications in the Richter Scale of Cultures is not necessarily an in-order listing of power per say, although that usually is the case. Attributes like planetary government and non-aggressiveness are factored in. Ratings higher than our own (N) are extremely speculative since more advanced beings and races are not always forthcoming about themselves and usually have no way of covertly or openly studying them.
