Planet does not have nearly as central a government as most of these alien worlds. They don't even really have countries, exactly. What they do have is a lot of different competing organizations, often doing the same sorts of things as each other with small twists. One of the groups reading through any alien literature that happens to be shared to them is The First-Glance Readers, a well regarded critic service that makes its money with a small government subsidy (that can be taken away if they stop being a public good) and donations from readers, or from whoever will pay to have a work added to the top of the stack (sometimes authors and sometimes fans).
They rate fiction from 0 to 10 along three dimensions. Almost nothing ever scores a zero or a ten, most follow a bell curve. The four ratings allow different readers to look for different things depending on their mood. Sometimes you want a power fantasy, and sometimes you want a more detailed drama. They are shallow-uncomplicated-fun (Flash), Meaningful-thoughtprovoking (Deep), compellingness-to-read (Flow), and verisimilitude-and-technical-detail (Learn).
One of those critics takes themselves to a carefully neutral and bland room without any decoration and a white noise generator, clears their mind, and tries to read each incoming submission as naively as possible so they can provide accurate impressions of it.
