Some though do show huge promise, intelligence, and have extremely useful skills, many top scientists and engineers are not Judges. Most of the cities biggest advancements in areas such as food, new materials, non weapon or military technology, medicine and architecture and construction design (including the Halls of Justice) came from ordinary citizens. All the major businesses and entertainment (apart from Justice Department propaganda channels) figures are citizens as are a lot of the city's diplomats, but they always report to a Judge before making any decisions. Not all valued skills are the same as the real world ones, examples of this are human taxidermy and professional gluttony. Most of the highly intelligent citizens end up in crime such as PJ Maybe, and Nero Narcos, as they are very limited in the wealth or power they can attain (the amount of real power a citizen can gain though is very limited) legally.
