Folkskolereformen (English: The public school reform) is a decision available to 
Sweden, which improves Sweden monthly research points by 1%.
The only requirement is to have researched Ideological thought, which can be researched in the beginning of the game. It is generally wise to get this decision as early as possible so the positive effect lasts as long as possible.
The ingame text says:
Folkskolereformen', The 'People School' Reform, was a law passed in Sweden in 1842 that introduced compulsory schooling for all Swedish children in a number of basic subjects, provided for by the state.' Folkskolan' would remain the basis of Sweden's educational system up until the early 1970's, when it was sadly phased out in favor of ignorance and poor grammar.
The in-game text is obviously a political comment by Swedish Paradox.
