Most are poorly educated and many can barely read or write, some sectors are said to be entirely illiterate, but Judges aren't that concerned, as it makes it easier for them to control and they can weed out the more intelligent simply when major crimes occur. Those that can read though are not much better, for example, when a book that detailed how to commit suicide was released, thousands of previously non suicidal citizens (including the book's author) killed themselves since they had read how to do it in the book. At one point in some of the more dangerous blocks, the Judges took to putting sedative drugs into the air systems to help keep the citizens more docile and easier to control.
